ventral pair bearing one extremely long hair; sub-caudal arrange- 
ment with the transverse rows of hairs large and comparatively 
few in number. 
The pupa may be distinguished by the blunt breathing horns with 
the enlarged tips, the weak character of the hairs forming the trans- 
verse sub-caudal rows on the abdominal sternites. 
The larva- have been found in several widely separated localities 
and the following general statements seem to apply: It is found 
in rich organic soil, sometimes rather dry, at other times more satur- 
ated; in "The Glen," Ithaca, N. Y., this soil is very dark brown, in 
Simmons' Woods, Gloversville, N. Y., almost black in color. Their 
haunts are almost invariably surrounded by tall shade trees. Small 
streams are always near at hand and the larva may well begin its 
career in the water. This habitat is quite different from the sandy 
or gravelly situations in which the larvse of Eriocera and Hexatoina 
occur. The lar\ae have all of the Hexatomine characters and the 
quick, active movements of their relatives. However, the bright 
yellow coloration of the body is quite distinct from the known larvae 
of the other genera. The record of the occurrence of these larvae 
is as follows: 
March 27, 1914 — Rich organic mud was sifted to-day ("The 
Glen," Ithaca, N. Y.) and one larva was found in association with 
the larv;p of other crane-Hies, Rhaphidolahis tenuipes O. S., com- 
mon; RhypholopJius nubihis O. S., a few; Molophilus hirtipeunis O. 
S., abundant, and other Tipulid larvae; also a few of Dixa modcsta 
Johann. (=cUn'iiliis Will. ( ?) ) • This larva was placed in a vial and 
was seen alive at various dates until June when it was no longer to be 
found. The vial was examined on June 30, but no part of the insect 
could be detected. 
April 10, 1914 — More of the rich organic mud from "The Glen" 
was examined and five larvae found; 2 were placed in vial No. 17, 
1 in vial No. 18. These vials were examined on June 30, vial 17 
was spoiled; vial 18 contained one healthy larva, rather small. 
April 17. 1914 — More nuid from "The Glen," one larva being 
found. Natural associates at this time were the larvcC of the fol- 
lowing crane-flies: Rhypliolophiis nubihis O. S., R. n'ujnpihis O. S.,
