narrower at base than apex, usually distinctly punctured at base and apex, rarely 

 feebly so at apex; apex feebly emargrnate, the anterior angles rounded, not 

 prominent; transverse impressions rather feeble; median line abbreviated in 

 front; basal impressions broad, deep, bifoveate, the fovese subeonfluent; base 

 subtrnncate; sides arcuate, sinuate in front of the hind angles, which are rec- 

 tangular and strongly carinate ; margin wider than in hlanchardi and translucent. 

 Elytra together scarcely wider than the thorax and less than twice as long as 

 wide, deeply striate ; strise entire, punctate nearly to apex, less deeply behind 

 the middle, the scutellar stria long, the eighth with the row of ocellate punc- 

 tures rather widely interrupted at middle; intervals feebly convex; humeri 

 feebly subangulate. Body beneath piceous or nearly black ; meso- and meta- 

 sternal episterna and sides of metasternum rather sparsely punctured. Legs 

 dark rufous or rufopiceous, the inner margin of the middle and hind femora 

 with four or five setigerous punctures; tarsi not grooved on the outer side. 

 Length .45-.50 inch ; 11.25-12.5 mm. 



Ill the males the middle tibiae are normally dentate. 



Thi.s species agrees with stupida Lee. in the number of setigerous 

 punctures of the femora, differing from it by the thorax being more 

 narrowed behind and by the presence of an inner fovea in the basal 

 impressions thereof. From b/anchardi, which it closely resembles, 

 it is sufficiently distinct by the characters given in the table. 



It occurs along the Pacific Coast from southern California to 

 Washington. I have seen one specimen from Arizona. 



5. A. Stiipi<lR Lee. — Form slightly elongate, convex, the elytra flattened 

 on the disk. Color piceous, the elytra rufopiceous (in the type) or piceous. 

 Head scarcely narrower than the thorax at apex; frontal grooves short, deep, 

 not extending anteriorly on to the epistoma; antennae slender, shorter than the 

 head and thorax, rufous; palpi rufous. Prothorax nearly twice as wide as long, 

 very sligiUly narrower at base than apex ; apex slightly emarginate, the anterior 

 angles rounded, not prominent; transverse impressions obsolete; median line 

 distinct, abbreviated in front; basal impressions small, the inner fovea obsolete, 

 the outer deep, close to the hind angle; base and apex punctate; base truncate; 

 sides with the margin narrowly reflexed, arcuate, sinuate immediately in front 

 of the hind angles, which are rectangular, slightly prominent and carinate, the 

 carina rather broad. Elytra together scarcely wider than the thorax, more than 

 one-half longer than wide, dee])ly striate; humeri rounded; striae entire, dis- 

 tinctly punctate to behind the middle, the scutellar stria moderate, the eighth 

 with the row of ocellate punctures widely interrupted at mfddle; intervals 

 slightly convex. Body beneath rufopiceous; meso- and metasternal episterna 

 and sides of metasternum and of first two ventral segments sparsely jjunctate. 

 Legs dark rufous; middle and hind femora with four or five setigerous punc- 

 tures along the inner margin; tarsi not grooved externally. Length .48- .50 

 inch ; 12-12.5 mm. 



Most nearly allied to jacobina, from which it difiers by the thorax 



being less narrowed behind and the complete absence of the inner fovea
