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 larvae 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 larvae of Eriocera and Hexatoma 

 occur. The larvae 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 larvae of other crane-flies, Rhaphidolahis tenuipes O. S., com- 

 mon; Rhypholophus niihihis O. S., a few; Molophilus hirtipennis O. 

 S., abundant, and other Tipulid larvs; also a few of Dixa modesta 

 Johann. {=clavidus 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 mud from "The Glen," one larva being 

 found. Natural associates at this time were the larvae of the fol- 

 lowing crane-flies: Rhypholophus nuhilus O. S., R. nigripihis O. S.,
