SYNONYMICAL AND DESCRIPTIVE NOTES ON NORTH 

 AMERICAN ORTHOPTERA. 



BY SAMUEL H. SCUDDER, CAMBRIDGE, MASS. 



In a review of N. A. Decticin?e (Can. Ent., XXVI.), I referred 

 (p. 180) an undescribed Pacific Coast species provisionally to Drymadusa, 

 an Old World genus of which I had not then seen specimens. Direct 

 comparison shows that it differs from that genus in the lack of a humeral 

 sinus on the posterior border of the lateral lobes of the pronotum and in 

 the great posterior extension of the pronotum. I propose for it the 

 generic name Apote (u-, -oT>y). The species, which may be called A. 

 notabilis, is testaceous, tinged on the pronotum with olive-green, the 

 abdomen fusco-testaceous, much and minutely marked with black and 

 light testaceous, the tegmina abbreviate but attingent, testaceous with 

 black veins. The length of the body is 37 mm.; of the ovipositor, 28 

 mm. Oregon. 



We have, however, another genus of Decticina^ not given in my table, 

 consisting of long-winged species still more nearly allied to Drymadusa, 

 but separable from it by the slender form, much narrower head and 

 fastigium, narrower tegmina and the less incrassate base of the hind 

 femora, and by the presence of spines on both sides of the under surface 

 of the fore femora, though these are inconspicuous on the outer side of 

 one species. It may be called Capnobotes {KUTrvoftoTr)^) in allusion to 

 the smoky aspect of the insects. 



To this belong two species described by Thomas and referred to 

 Locusta, and which I had not determined when I published my former 

 paper. Prof. L. Bruner has kindly sent them to me, as well as two other 

 species, one of them from Lower California. The three United States 

 species may be separated by the following table : — 



a.' Outer margin of fore femora distinctly spined beneath; melazona con- 

 siderably elevated above the pro/ona, so that the pronotum is subsel- 

 liform.
