beneath only in apical third or fourth; hind tarsi about as long as the 

 tibiae. Length (cT) 13.5 mm.; width 6.3 mm. California (Monterey), — ■

This species is very distinct from gentilis in its much smaller 

 size, relatively smaller prothorax, narrower head and coarser elytral 

 punctures and striation; in many respects it closely resembles 

 integer Csy., but the strial punctures are more close-set and the 

 side margins more narrowly reflexed and not at all violaceous, as 

 they are feebly in integer, and the head is relatively a little narrower, 

 with less prominent eyes; the anterior tarsi are of similar structure 

 in these two species and the size of body is notably small. The 

 elytral humeri are more completely obliterated in montereyensis 

 than in either gentilis or integer. 



The following species is related rather closely to lativentris Mots. 

 (ventricosus Csy. nee Dej.), but has a relatively larger and unusually 

 abbreviated prothorax, flatter strial intervals and longer legs, 

 especially observable in the tarsi; it inhabits the Sierras, while 

 lativentris occurs near Sta. Cruz on the coast: 



Brennus brevicollis n. sp. — Rather large in size, very convex, alutaceous 

 anteriorly, the elytra shining but micro-reticulate, the surface nowhere 

 metallic; head rather large, twice as long as wide, a little more than half 

 as wide as the prothorax and somewhat wrinkled transversely anteriad; 

 antennae slender, the fifth joint five times as long as wide; prothorax a 

 sixth wider than long, the sides moderately reflexed, obtusely somewhat 

 prominent at the middle, thence rounded and converging to the rounded 

 apical angles and more converging and nearly straight to the basal sinus, 

 which is in line with the subbasal sulcus, thence parallel to the basal 

 angles, which are rounded; base transverse, more than half the maximum 

 width, the transverse impressions distinct but shallow, the median stria 

 fine but deep; fove« very short and faintly impressed; surface with 

 numerous fine transverse creases; scutellum very short and broadly 

 rounded as usual; elytra three-fifths longer than wide, two and two- 

 fifths times as wide as the prothorax, obliquely acuminate in about'apical 

 third, the arcuate sides more rounded at base, the humeri as in lativentris; 

 striae rather fine, impressed, about eleven of them regular and with 

 moderate, widely spaced punctures, thence more or less confused, coarser 

 and somewhat more coarsely punctate in about outer two-fifths of the 

 width; margins narrowly reflexed, not metallic. Length (9 ) 19.0 mm.; 

 width 9.3 mm. California (Mokelumne Hill, Calaveras Co.),— Blaisdell. 



The epipleura have some sparse moderate punctures, more 

 evident than in lativentris, but the inner submarginal line of punc- 

 tures is much less definite than in that species, where also the 

 sides of the prothorax are more widely reflexed.
