CARABINE 29 



Differs from incipiens in the angulate sides of the prothorax, 

 these being strongly but evenly rounded at the point of greatest 

 width in incipiens, and in the latter the sides toward base are still 

 converging, not subparallel as in congener; the pronotum is more 

 shining and more coarsely rugulose in incipiens. Both of these 

 forms are possibly subspecies of rugiceps. 



Brennus productus n. sp. Elongate, ventricose, only very moder- 

 ately convex, black, alutaceous throughout, the elytra rather more shining; 

 head as in ventricosus but much narrower, the labral lobes similar but 

 less diverging; supra-orbital puncture feeble but evident; prothorax 

 differing greatly, being small and narrow, more nearly as in striatus, 

 fully as long as wide but apparently somewhat elongate, the sides an- 

 teriorly inflated and broadly rounded, thence oblique posteriorly, then 

 sinuate, becoming straight and parallel for an unusually long distance 

 before the base, this being fully a fifth the total length; sides strongly 

 re flexed but not so strongly as in ventricosus; surface nearly as in the 

 latter; base narrower and broadly sinuate as in oreophilus, one-half the 

 maximum width; elytra evenly elliptic, one-half longer than wide, finely 

 but deeply about ij-striate, the striae very regular and with rather small 

 punctures, becoming coarser laterally, the striae outside the thirteenth 

 much confused and barely traceable; intervals convex; margins strongly 

 reflexed, not metallic; anterior tarsi (cf) nearly as in the preceding 

 throughout. Length (cf ) 15.7 mm.; width 7.0 mm. California (exact 

 locality unrecorded but probably coastal). 



The general appearance of this species is unlike any other known 

 to me but seems to approach striatus more closely than ventricosus; 

 the probabilities are that it will prove to be of specific rather than 

 subspecific value and it is therefore so announced. 



Brennus integer n. sp. Body small in size, strongly ventricose, very 

 shining and deep black throughout, the reflexed margins of the elytra 

 violaceous; head moderate, smooth and shining along the middle, with a 

 supra-orbital seta; antennae slender, about as long as the elytra; prothorax 

 relatively small, rather wider than long, the sides inflated and evenly 

 rounded anteriorly, rapidly very oblique posteriorly, abruptly sinuate 

 near the base, the sides thence parallel and straight to the base, which is 

 transverse and distinctly less than half the maximum width; surface 

 shining, finely subrugulose, feebly impressed along the sides, the trans- 

 verse impressions and median stria strong, the margin strongly reflexed; 

 elytra oval, obliquely attenuate and sharply pointed posteriorly, very 

 convex, with fourteen deeply impressed striae, complete and perfectly 

 regular throughout the width, not at all confused laterally, the punctures 

 not large and but slightly crenulating the very convex and perfectly even 

 intervals throughout, the latter very highly polished; male with the 

 anterior tarsi rather feebly dilated; joints two and three and less than 

 apical third of the first densely spongiose beneath. Length (cf) 12.4 

 mm.; width 5.8 mm. California (Sta. Cruz).
