esting also, because it oilers a transition form to the Odonala. 

 A comparatively slight decree of consolidation of the labial 

 parts here present, and a slightly better development of the I \\ o 

 points ai the tip of the palpus (of which the last joint is homo 

 logons with the movable hook, and the internal prolongation of 

 I lir preceding joint equals the end hook of the Odonata), would 

 give the grasping labiuiu, so characteristic of the nymphs in 

 that order. 



Much has been written concerning the anatomy of this inter- 

 esting species especially the anatomy of the nymph. A full 

 bibliography and a new description with some excellent figures 

 are given in Katon's Monograph, pp.L'1'i; _!".. pl.21 and 4 



Less is known concerning its manner of life. In a general way 

 it may lie said to inhabit the more rapid portions of our larger 

 rivers and to be very local. It is rare in collections.

This is the common Ithaca species, whose nymph is figured on 

 page 87 of Comstock's Mint mil for the Study of Insects. It has 

 been referred hitherto to C h. s i e c u s Walsh. It differs from 

 Walsh's description of that species in its larger size, later sea- 

 son of appearance, separateness of eyes in male subimago, colora- 

 tion of front tarsi and of forceps and in conspicuous black trans- 

 verse apical lines on abdominal segments. It agrees better 

 with Eaton's description and fairly well with his figure of that 

 species, but I doubt whether Eaton had the species of Walsh. 

 Pending the reidentification of Walsh's species, I think that less 

 confusion will result if this one be kept apart under a new name. 



This species is abundant in all the rapid streams about Ithaca. 

 I have observed the nymph, especially in those places where the 

 creek lied is Hat slu-lving rock over which 1he water streams in a 

 thin sheet. In such places the flat, rocky floor of the stream is 



'Lost it he not dis'-erned. T will state openly Hint the common name 

 "howdy," which I apply to the members of this genus, is a very free trans- 

 lation Into western vernacular of the generic name.
