The adult flies of the various species of Dicranoptycha are usually 
abundant where they occur. They may be found resting on the upper 
surface of leaves of shrubbery and tall herbage in open woods, often far 
from water, which is not so necessary for development as with most 
species of Tipulidae. 
Subtribe Rhamphidar‘a 
The division Rhamphidaria includes the genus Rhamphidia, with the 
possible addition of a few exotic genera. Rhamphidia is one of the con- 
stituent genera of the former group Antochini, but differs considerably 
from all others whose life histories have been made known. ‘The closest 
relatives of Rhamphidia seem to be the Dicranoptycharia, on the one hand, 
and the lowermost divisions of the Hexatomini, on the other. The 
larvae and the pupae of Rhamphidia present a curious eriopterine appear- 
ance, but their structure indicates only a distant relationship with the 
Eriopterini.

Larva.— Body terete. A transverse welt, covered with microscopic scabrous points, on 
ventral surface of basal annuli of abdominal segments 2 to 7. Spiracular disk surrounded 
by five short lobes which are fringed with abundant, rather long, hairs. Head capsule 
massive, generalized in structure. Mandible short and stout, ending in two subequal blunt 
teeth. Maxilla consisting of two rather short, densely hairy lobes. Antenna short. 
Hypopharynx chitinized, outer margin with about a dozen teeth. Mentum not completely 
divided, with five teeth. Coloration of body dark brown, produced by the dense appressed 
pubescence covering it. 
Pupa.— Cephalic crest double, the anterior part low, the posterior part the larger; lobes 
setiferous, divergent. Two setae on front between eyes. Pronotal breathing horns long 
and slender, slightly curved. Mesonotum convex. Wing sheaths reaching end of second 
abdominal segment. Leg sheaths ending just before posterior margin of fourth abdominal 
segment; all the tarsi about equal in length, or those of fore legs a little longer. Abdominal 
segments with two narrow basal rings and a broader posterior ring having four narrow 
transverse bands of spicules and comparatively few setae. Spiracles rather large on 
pleurites 2 to 7, and a large conspicuous pair on dorsum of segment 8. 
Rhamphidia is a small genus of crane-flies (about thirty-five species), 
widely distributed thruout the temperate and tropical regions of the world. 
The larvae of the European R. longirostris Meig. were found by Gercke
