I'NDESCRIBED SPECIES IN THE OSTEN SACKENCOLLECTION OF NEW ZEALAND
CRANE-FLIES(Diptcra,Tipulide)
Bv CHARLES P. ALEXANDER
Subsequent to his return to Europe and the selection of his
final abode in Heidelberg in 1877, Baron Osten Sacken
amassed a very considerable collection of the crane-flies of
New Zealand, chiefly through the efforts of Prof. George V.
Hudson. From these rich collections only a very few of thenelv specieswere described by Osten Sacken, but in the intervening period additional collections by Hudson have been carefully studied and reported upon by Captain Hutton, so thatmost of the species have now been diagnosed.
A proportion of this crane-fly material ultimately'came into
the possessionof the German Bntomological Museum at BerlinDahlem, and through the kindness of the Director, Dr. Walther
Horn, the writer has been able to examine some of the doubtful speciesin this collection, and the new speciesresulting fromthis study are discussedin this paper. The types of the novelties are preserved in the collection of the German Entomological Museum, and paratypes of certain of the speciesin thecollection of the writer.
I wish to express my sincere thanks to Dr. Horn for theprivilege of examining this historical collection of crane-flies.

The specific name, bona, applied to this species is a manuscript name of Osten Sacken's, appearing on some of the pins.
The fly is remarkably distinct from other New Zealand species,
the long, narrow wings suggesting the early stages of wing-

atrophy. This may be the speciesmentioned by Osten Sacken(Berl. Ent. Zeitsch., vol. 31, pt. 2, p. 211, 188?) as having
rudimentary wings in both sexes.
Gynoplistia sackeni, new species.

segment reddish brown; flagellum dark brown; antenna with
1? segments, the first to thirteenth flagellar segments withlong, flabellate branches, the longest exceeding in length thebasal f our flagellar segments taken together; terminal twosegmentssimple; the pectinations are provided with long, erectpubescence,each tipped with one or two bristlelike verticils;
the pectination of the first flagellar segment is about threetimes the length of the segment that bears it, that of thethirteenth segment about as long as the segment that bears it.
Head dull gray; a large blackish spot behind each antennal
base; occiput reddish.
Mesonotum light gray, the praescutum with three reddish
brown stripes, the median stripe broadly divided by a grayline; remainder of the mesonotum brown, heavily gray pruinose. Pleura reddish, heavily light gray pruinose. Haltereslight brownish yellow, the knobs darker brown. Legs with thecoxre light gray pruinose; trochanters light yellow ; femora

suddenly constricted at about three-fifths the length, the apex

Holotype, 6, Wellington, June, 1895 (G. V. Hudson).
Gynoplistia sackeni, is presumably the species mentioned by
Hutton (Trans. New Zealand Inst., vol. 32, p. 46, 1900) as avariety of. G. wakefieldi Westwood in which the flagellar pecti
nations are unusually elongate; the antenne are but 17 segmented, however, and this latter may pertain to still anotherspecies. It is clear that several speciesare confused under thenames of. G. swbfasciatoWalker and G. zuakefiieldiWestwood,the number and degree of pectination of the flagellar segments
being far too great to fall within the definitions of the above
species.
