I take great pleasurein naming this interestingcrane-fly inhonor of the collector,ffiy f ormer stuclent,Dr. Harry DavisPratt. From the other describeclspeciesof the obscura grolrp,
the present fly is closestto obsruya (Johnson), tri.dentit'ulata
Alexander, ancl f olitu, (Johnson) , especiallythe last. The
shapeof the nrecliarrtergal lol;e is much the same in the twoflies but the other details of structure of the hypopygium ofpolito.are quite distinct, especiallythe more expandedlateral
tergal arms, the bulbousbasalenlargementof the long blackened
outer dististyle,the tuft of lorrger setaeon outer face of theinner dististyle, and the clifferently constructedgonapophyses
with more abundant armature. All of these speciesdiffer
further in the length ancl structure of the antennae.

long as the more clavate upper branch; besidesthis arm, thelobe is produced into an even larger and longer blade that
gradually tlarrows to the pale olrtuse apex. Dorsal dististylea small, sickle-shapedrod. \'errtral dististyle with the main

IJtrlv,Brower, to whom I am very greatly indebted for many interesting Tipulidae from Maine and from interior Gasp6. The
nearest ally is Limonia (Dicranornyio) mognicouda (Lundstrtim) of northern Europe. While both speciesagree in thegreat size of the male hypopygiumand in the generalstructuresof the same,yet all details of the tergite and the various lobesof the basistyleand ventral dististyleare distinct in the twoflies.
Dicranoptycha tennessan. sp.
General coloration brownish gra!, the praescutum with aslightly darker median stripe; antennaewith scape brownish
black; pleura light gray, the anepisternumand ventral sternopleurite darkened; Iegs obscure yellow, the femora with thetips rather narrowly infuscated; wings with costal fringe(male) unusually long and conspicuous;abdominal tergites

Rostrum black, sparselv pruinose; palpi black. Antennae

black setae.
Pronotum brownish gray. Mesonotal praescutumbrownish
gray, with a more or lessdistinct, darker brown, median stripe,
the lateral stripes less evident; posterior scleritesof notum

This interesting fly was incruded in extensive series ofTipulidae from the Great Smoky Mountains,receivedfrom myfrierrd,Dr. Arthttr C. Cole,to whom I am greatly indebtedfor
nranY favors. The speciesis allied to Dicranoptychasobrina
Osten Sackenand ltrobabl-vhas beenconfusedwith this in collections. Both specieshave the costal fringe of the male longand very conspicuous.The presentfly has the darkenedapicesof all femora subequalin amount and has a very difierent malehypopygium, with both the outer dististyle and aedeagusunusually broad and flattened.
