of the male are usually shorter, being no longer than broad (fig. 10). 

 The anterior tibiw are armed above on the outer margin with two 

 spines and on the inner margin with one apical spine. The color of 

 the male is a light yellowish brown, the sides of the pronotumand por- 

 tions of the posterior femora more or less infuscated and all the legs 

 rather obscurely banded as in the t3"pical form. The female has the 

 disk of the pronotum a uniformly yellowish 

 brown, the lateral lobes black with the lower 

 and hinder margins narrowly emarginate with 

 yellowish brown. The abdomen is colored as 

 in typical carinata and the antennae of both 

 sexes are banded as describe dunder that form.

Specimeni< examined. — One male, Mount Shasta, California (Behrens, 

 collector), and one male, one female, Napa County, California (Edwards, 

 collector). 



This variety, of which the pair from Napa County, California, were 

 loaned me for study by William BeutenmiiUer, of the American jNluseum 

 of Natural History, of New York, is quite distinctive in general appear- 

 ance. I have hesitated to call it a distinct species, though it may 

 eventually prove to be such. 



NEDUBA MORSEI, new species. 



Dese7'ij)tio/). — In general appearance, both as to form and color, this 

 species is very similar to carinata. The pronotum is somewhat mot- 

 tled, as in carinata ■picturata^ and the lateral carina? are slightly 

 bowed outward behind the point of greatest constriction. ,The most 

 important characters, however, that serve to separate it from its ally, 

 carinata., lie in the male abdominal characters. Here the last abdom- 

 inal segment is apically rounded, instead of truncatel}" sinuate as in 

 carinata., and the infracercal plates are long, slender, and internall}^ 

 armed near the tip with a short spine or tootli; that part of the infra- 

 cercal plate projecting ])eyond the last abdominal segment is three 

 times as long as broad, instead of scarcely longer, as in the other forms 

 (fig. 11). The cerci are about two times as long as the basal width, 

 instead of three or four times as long. The anterior tibiae are armed 

 above on the outer margin with three spines.
