impressed at middle on the first three segments; posterior tibiae more 

 or less feebly arcuate. 



Measurements. — Males: Length, 20-27 mm.; width, 7-10 mm. 

 Females: Unknown. 



Genital characters., male. — Edeagophore comparatively large, ob- 

 long-ovate, very elongate and slightly arched. 



Basale elongate oblong, evenly convex from side to side, moder- 

 ately strongly convex antero-jiosteriorly, with a moderate longitudi- 

 nal impression at middle in ajiical moiety; sides subparallel ; surface 

 glabrous and shining, sparsely punctate apically at the sides; apex 

 with a rounded emargination at middle. 



Apicale triangular. Surface convex laterally, with a depressed 

 oval chitino-membranous area at the middle, thence to apex broadly 

 and not deeply grooved; apex recurved and quite broadly rounded; 

 sides quite straight, although feebly but broadly sinuate at apex; 

 base with a well-marked, rounded lobe at middle and quite strongly 

 sinuate lateral!}-. 



Stei'nite subparabolic in outline and slightly transverse. Each 

 lobe with the external border quite evenly and broadly arcuate from 

 base to apex, the latter narrowly rounded; internal border short and 

 arcuate; surface quite convex, glabrous in basal half, thence to apex 

 strongly punctate, the punctures increasing in density, each with a 

 rather long seta, the latter dense in apical third. Sinus broad and 

 more or less oblong-oval, the inner and contiguous surface of the 

 lobes inwardly and gradually declivous. Membrane not setose and 

 irregularly rugose. 



Habitat. — California. The exact locality is not indicated on the 

 specimens at hand. LeConte's cotype before me bears a green 

 " Calif." label, but in his description of the species he gives San 

 Diego, California. 



All the specimens that T have seen and which were referred to 

 f/entil/s by Doctor Horn have thus far turned out to be something 

 else, and I am not sure that he had typical specimens in any of these 

 instances. 



(roitilix^ no doubt, occurs in Central and Lower California, as well 

 as in the southern part of the State. 



Tjower California specimens" referred to f/entilis by Horn were 

 hisi/hu'ls or some variation of omissa. Colonel Casey failed com- 

 pletely to recognize gentilis^ and considered the race described in this 

 paper as pygmwa as that species, saying that it is abundant at San 

 Diego.'' I have a specimen which he identified as gcntilis. It is 

 simply a pygmcea with a very quadrate prothorax. 



Pijgma'a is abundant at San Diego, but gent 11 is seems to be very 

 rare, for I have not seen any recently collected specimens. During
