Plate II., Fig. 5. 



Head, legs, and lateral lobes of pronotum resembling cris- 

 tatus. Pronotum anteriorly angulate produced, posteriorly 

 subulate, rugose, between the shoulders transversely strongly 

 tectiform; pronotal process extended backward beyond the 

 knee of posterior femora; median carina of pronotum a little 

 compressed, longitudinally slightly convex, a little higher over 

 the shoulders, posteriorly gently concave. Wings explicate, 

 extended a little beyond the process. 



Length of body, $, g.2 mm.; pronot., 11.8 mm.; post, 

 fem., 5.3 mm. 



Morse gives the following measurements: $, 11-11.5 mm.; 

 pronot., g. 5-10.7 mm.; j, 11-12.5 mm.; pronot., 9.8-11.5 

 mm.; posterior femora breadth contained 2.5 times in the 

 length; pronotum extending beyond the posterior femora; $, 

 2-3 mm.; $, 1-2.8 mm.; wing extension beyond pronotum, 

 $, .4-. 8 mm.; $, .3-1 mm.

Morse maintains that carinatus is a reversion to the earlier 

 long-winged type of female cristatus, consequently a variety 

 of that species. 



The proportion of the former to the latter individuals, as 

 determined locall)', is one or two to the hundred in Massa- 

 chusetts, where observations were made. It is found associ- 

 ated with cristatus.
