ROLAND HAYVVARD. 47 



ti sliglit distance in front of the base and the hind angles are sub- 

 rectangular. Its size is the same as longula (.27-.34 inch ; 6.75- 

 8-5 mm.). 



It occurs along the Pacific Coast from British Columbia to San 

 Diego, California, extending eastward probably nearly to the Rocky 

 Mountains, specimens being known to me from Idaho and Utah. 



32. A. belfragei Horn. — Oval. Piceous, surface slightly bronzed, shining. 

 Antenn;e rufotestacet)ns. Prothorax half wider than long, impuuctate, arcuately 

 narrowed to the front. Elytra finely striate, more deeply at apex ; sixth and 

 seventh lateral strife almost obliterated. Body beneath piceous, smooth, shining, 

 slightly metallic; epipleurie slightly paler. Legs rufotestaceous. Length .32- 

 ..■)4 inch ; 8-8.5 mm. 



Separable from the other species of Triceua by the characters 

 given in the table. 



It occurs at Waco, Texas. 



33. A. aroveolata n. sp. — Elongate-oval, slightly convex ; form nearly as 

 in longula. Black, scarcely metallic, shining. Head as wide as the thorax at 

 apex; frontal grooves distinct; antennae shorter than the head and thorax, 

 piceous, the first three joints and the fourth at base rufotestaceous; palpi 

 piceous. Prothorax scarcely one-half wider than long, impunctate, very feebly 

 emarginate at apex, narrowed from about the middle to apex ; sides with the 

 margin narrowly reflexed, arcuate in front, subparallel behind, the posterior 

 setigerous puncture in the hind angle, equidistant from basal and lateral mar- 

 gins; transverse impressions obsolete; median line very fine, abbreviated in 

 front; basal impressions distinct, the inner fovea longer than the outer; base 

 very feebly bisinuate ; hind angles rectangular, not carinate. Elytra scarcely 

 wider than the thorax, finely striate; strite entire, very finely punctulate to 

 behind the middle, the scutellar stria without ocellate puncture at base, the 

 eighth with the row of ocellate punctures interrupted at middle. Body beneath 

 black, slightly seneous, impunctate. Legs piceorufous; apical spur of anteiior 

 tibite with the inner lobe acute. Length .29-. 32 inch ; 7.25-3 mm. 



Differs from all our other species of Tricena by the absence of the 

 ocellate puncture at the base of the scutellar stria of the elytra. 

 From longula, which it most nearly resembles in form, it differs also 

 by the impunctate under side of the body, while another character 

 for its separation from scitula is afforded by the color of the legs. 

 The thorax is also of slightly different form from that of the last 

 named species. 



Described from one nuile and two females in the LeConte collec- 

 tion. Of these, two are from Vancouver Island and one from 

 California.
