California (Ojai). Mr. H. C. Fall. 



Although to be placed near puberulus for the present, this 

 species bears but little resemblance, differing completely in the 

 form of the prothorax. The anterior trochanters of the male type 

 before me are acutely spiculate posteriorly near the base, but there 

 are no pronounced sexual characters at the ventral apex, the last 

 segment being truncate at tip and having a very small median 

 sinus limited by rather pronounced and somewhat prominent ob- 

 tuse angles. 



Ctenistini. 



PILOPIUS n. gen. 



Ctenistes Lee. nee Eeich. ; Sognorus Csy. nee Reitter. 



The American species formerly placed in Ctenistes by LeConte, 

 and later in Sognorus by the writer (Col. Not. y,p. 501), must in 

 reality form a new genus distinct from either. Sognorus was 

 founded by Reitter upon three species of very small size, Ctenistes 

 oherthuri and calcaratus of Europe and Syria and simonis of 

 West Africa, the latter of which I now have before me. It differs 

 from Ctenistes, not only in the minute size of the body and cer- 

 tain small divergencies in antennal and abdominal structure, but 

 also in the rudimentary and not well developed appendage of the 

 second palpal joint. Pilopius differs from Sognorus in having the 

 second palpal joint extremely bent and clavate, with a well-de- 

 veloped lateral appendage and the third transversely sublunate, 

 the second and third ventrals not much longer than the fourth and 

 the first four visible dorsals equal in length, also in the much 

 larger size of the body and in having the male antennas very dif- 

 ferent in structure, the funicular joints being longer and the club 

 3-jointed. From the genus Ctenisodes, recently published by 

 Raffray (Ann. Soc. Fr., LXY, p. 2H), it differs in having no 

 distinct trace of an angulation or spiniform appendage at the apex 

 of the fourth palpal joint. 



In Sognorus the second palpal joint is much less bent and more 

 gradually enlarged distally, the third forming a very acute scalene 

 triangle, and the second and third ventrals, or first and second 

 apparent dorsals, axe much longer than the remainder; the an- 

 tennae of the male have the joints three to seven very small and 

 moniliform, and the last four very much developed as in Ctenistes 

 and Ctenisis. Sognorus seems to be merely a subgenus of Ctenis-
