The precedingpart under this general title was publishedin the Transactions of
the ShikokuEntomologicalSociety,Vol. 10, No.2, March 1969. In the presentpaper
I am consideringspeciesof Tipulidae that were collectedin Honshuby Dr. Kintaro
Baba and Mr. Toshio Mishima, to both of whom I expressmy deepest thanks forcooperationin making known the Japanesecrane flies. In addition to the novelties
here describedI am discussingthree further speciesthat involve new synonymiesand
distributional records.

There are several related regional members of the punctulata group, the mostsimilar being Limonia (.Dicranomyia)f oti Alexander, of easternAsia. This has celllst Mz closed and with the gonapophysesof the hypcpygium bidentate. The present
fly is unique in this group of species in the open cell Mz of the wings, as described.
The condition is identical in both wings of the type and is presumeCto represent a
normal condition.

The spe:ies is dedicateCto Mr. Toshio Mishima who has addeCmaterially to ourknowledge of the Japanesecrane flies. It is quite distinct from other regional species
and possessesseveral plzzling features. The broad light silvery anterior vertex
suggests the condition found in the subgenus Melanolimonia Alexander, while thetwo-segmented palpi are much as in the otherwise entirely distinct Limonia (Dicranontyia) uentralis (Schummel) of northern Europe and Asia (synonym, perserotina
Alexander, from Ompo, North Korea ; Trans. r. Ent. Soc. London, 95 : 24O- 24L; 7945).
The long slender rostral prolongation of the ventral dististyle of the hypopygium ismuch as in Z. (D.) gracilirostris Alexander, of western China which is entirely
distinct in all other regards.

dististyle with two long spines.
A.- Length about 5.5 mm ; wing 6.5 mm.
Rostrum and palpi dark brown. Antennae brown; proximal flagellar segments
short-oval to subglobular (outer segments broken). Head brown.

yellow. Mesonotal praescutum obscure yellow with three vaguely darker stripes,
central one obsolete on posterior half ; posterior sclerites of notum brownish gray.
Pleura brownish Br?y, propleura and dorsopleural region more yellowed. I{altereswith stem yellow, knob dark brown. Legs with fore coxae and trochanters brownish
yellow, remaining coxae dark brown, trochanters yellowed; remainder of legs
yellowed, femora with a very vague scarcely evident pale brown subterininal ring,70

The closest relative of the present fly is Limonia (Dicranomyia) handlirschi(Lackschewilz), described from Bohemia, Czechoslovakia, now known also from
northern Europe. Other less similar speciesinclude L. (D.) nielseniana Alexander, ofwestern North America and various others in the Himalayas. This species differsfrom handlirschi in coloration of the body, legs anC wings but the hypopygial
structure is very sirnilar in the two flies.

The Japanesemembers of the subgenus include four species where the darkened
wing pattern is restricted to the vicinity of the veins, these including Lintncphila(Eloeophila) kintaro Alexander and L. (8.) mishimai Alexander which are distinct
in the wing pattern and in having macrotrichia in the outer raCial wing cells. The
remaining species,L. (8.) subaprilina Alexander and L.(,8.)ussurica Alexander, aremore distinct in the wing pattern, the former having two darkeneC areas in the Analcells, the subterminal one being larger than the spot at enC of vein 2nC,4. The latter
specieshas the wings very weakly patterned and with the hypopygial structure quitedistinct, being very close to the western Palaearctic L. (E.) trimaculata (Zetterstedt)with which it may prove to be identical.

Only a few of the rather numerous species of. Prionolabis in Japan have theantennae l3-segmented and with cell Mr of the wings present, these including
Limnophila (Prionolabis) imanishii Alexander and Z. (P.) luteibasalis Alexander,
and, in some cases, L. (P.) yamamotana Alexander, where the number of flagellar
segments appears to vary becauseof the partial fusion of certain segments, in cases
to as low as 13. Of the above, both species are subapterous in the female sex and it ispossible that this condition likewise exists in the present fly; luteibasalis in themale
sex has the tergal lobe of the hypopygium with three lobules, and with the dististyles
and gonapophysis distinct. The male sex of imanishii remains unknown to me; thetype female was found by K. Imanishi at Bogoya, in Toyama, Honshu, walking onsnow on August 4, L92Band sent to me for determination by Dr. Tokunaga.

The most similar Japanesespeciesis Ormosia (Sclero|rocta)cinctifer Alexander,
which while generally similar, differs in important features, the most important
being the phallosomeof the male hypopygium. The trichiation of the wing cells in
cinctifer is similar, these being restricted to the outer cells but more numerousand
more widely distributed. Other specieswith the dististyle generally as in thesetwo
speciesinclude, in Europe, the subgenotype,danica Nielsen, and also sororcula(Zetterstedt), and in eastern North America, apicalis (Alexander) and innocens(Osten Sacken). A secondgroup of speciesthat apparently are referrable to thissubgenusinclude Ormosia fascibennis (Zetterstedt), O. hallahani Alexander, theJapaneseO. cata Alexander, O. depraua Alexandar, and O. praua Alexander,and
someothers. Where the immature stagesare known all of these have the somewhat

This specimen is smaler than the type (Length about 5.5 mm i wing 6 rnm) but
from the very distinctive male hypopygium is identical. The specilesis very isolated
and the subgenericposition cannot be affirmed at this time.
