NEW SPECIES OF PEMPHUS AND TRAGOSOMA 



i < 'oleoptera). 

 P>Y THOS. L. CASEY. 



The tribe Cyehrini of the Carabidae has ever been a favorite 

 with coleopterists, because of the large size and elegant form 

 of the species, although the colors are usually not so brilliant 

 as in ('ambus in fact throughout the entire genus Brennus, 

 excepting iitnrf/iiuthn and a few allied forms, the species are of 

 an intense black. Pemphus is similar in this respect, the lus- 

 tre however being invariably dark and not shining as in Breu- 

 nns. The genera of the books are, in my opinion, valid and 



not sul )gen era. 



I'KMi'HUS Motsch. 



The following species belongs near lon-yipes, and Mr. Kick- 

 seeker, to whom I am indebted for a fine pair, writes me that 

 the habits are similar to those recorded under my description 

 of the latter (Col. Not., VII, p. 331) ). the motions being rather 

 sluggish and the gait deliberate. 

 Pemphus opacus, u. sp 



Moderately convex, the elytra somewhat ventricose, broadening 

 to about apical third, black throughout and dull in lustre. Head 

 elongate, the eyes small ; vertex feebly convex, very slightly wrin- 

 kled transversely ; antennae long and slender, the basil joint thicker, 

 claviform, 2.7-3.0 mm. in length. Prothorax apparently very 

 slightly longer than wide, dilated and broadly rounded at the sides 

 distinctly before the middle, the sides sinuate toward base; surface 

 very feebly convex, the side margin moderately reflexed . Elytra 

 about a third longer than wide, nearly two and a half times wider 

 than the prothorax; sides broadly arcuate, the hnmeri not well 

 marked; surface finely and irregularly punctate throughout, each 

 elytron with two or three di*:;:il intervals which are nearly regular ; 

 side margins feebly concave, coarsely and unevenly punctate, the 

 reflexed edge smaller than tint of the prothorax. Under surface 

 more shining than the uppyr, the legs long and slender. Length 

 21.5-27.0 mm.; width fl 5-11.4 mm ; length of head and mandibles 

 6.0-G.7 mm.; length of hind (ib'r.i !). 5-11.0 mm. 



California (Sonoma Co. ). 



The male is smaller and Uss ventricose than the female and 

 has the anterior tarsi moderately dilated, with the basal joint 

 densely pubescent beneath in distinctly less than apical half. 



Since completing my revision of Brenuus ( 1. c., p. 305), I 

 have received a pair of B. fuller I Horn, from Mr. Wickham,
