minutely tumid at apex, the ligula obsolete, being represented only 

 by a feebly arcuate part of the margin. The chief peculiarity of 

 the species resides in the unusually long, nearly straight and slender 

 beak of the female, that of the male normally thick though rather 

 longer than the head and prothorax, densely squamulose and 

 angularly gibbous above at base. The following is another species 

 of the soror section, being smaller and much narrower, with finer 

 and much less dense vestiture above: 



*Trichobaris pueblana n. sp. — Oblong, rathei convex, black, clothed 

 above with slender reddish-gray decumbent scales, by no means so close- 

 set as in soror, the abdominal concavity of the male with scales nearly 

 as dense as those at the sides but of narrower form; beak (cf ) nearly as 

 in soror but shorter and slightly less thick, or ( 9 ) also as in that species 

 but still straighter and less thickened toward base; prothorax nearly 

 similar, small, a fourth wider than long, the sides strongly converging, 

 rounding and oblique in apical third, the sculpture apparently coarser 

 and in the form of long sinuous rugulse; elytra one-half (cf) to two- 

 thirds ( 9 ) longer than wide, parallel, rapidly very obtuse at apex, a 

 third (cf) to a fourth (9) wider than the prothorax, the striae coarse 

 and deep, indicated by feeble partings of the vestiture when normally 

 clothed, the intervals confusedly punctato-rugose; abdomen nearly as in 

 soror, the fifth segment narrower and more rounded at apex. Length 

 (cf 9) 4-6-5.0 mm.; width 1.8-2. 15 mm. Mexico (Puebla). Com- 

 municated by the Mexican National Museum. Three examples. 



The much narrower outline, smaller size and finer, less dense 

 vestiture of the upper surface, will readily distinguish this species 

 from the rather closely related soror. The male is relatively broader 

 than the female, a feature not observable in soror. 



A small section, represented by texana, cylindrica and insolita, 

 differs from any of the preceding, excepting the trinotata section, 

 in the narrower and more cylindric form of the body, and from all 

 others it differs in having no small denuded spots at the base of the 

 pronotum. The scales of the upper surface are usually more oval 

 and denser, but in specimens collected by Wickham at Puente de 

 Ixtla, they, though rather dense, become much more lineate in 

 form. Mr. Champion unites pellicea Boh., with texana Lee, but 

 if these Ixtla specimens represent the former — and from this locality 

 cited for it also in the "Biologia," they would seem to be so 

 considered by Mr. Champion — it is quite impossible for me to agree; 

 the prothorax in pellicea has a peculiarly transverse, subquadrate- 

 oval form, with parallel and arcuate sides, notably different from
