COLEOPTERA OF SOUTHERN CALIFORNIA. 239 



antennae and legs testaceous, the femora sometimes darker. Head rather 

 coarsely punctate; antennae reaching almost to the hind angles of the 

 prothorax. Prothorax about as long as wide, a little narrowed in front, 

 sides moderately rounded just behind the middle, and also slightly so 

 before the hind angles, which are a little acute; surface moderately closely 

 granulate-punctate, disk with two small impressions at the middle of the 

 base, a deeper longitudinal one each side extending to the middle, and an 

 elongate median fovea. The base is slightly longitudinally channeled 

 before the scutellum and between the small basal impressions, the channel 

 is smooth at the bottom posteriorly. There is also in some examples an 

 oblique impression extending from the lateral impressions inward and 

 forward toward the median fovea. Elytra but little wider than the pro- 

 thorax, nearly parallel, sides slightly sinuate; the rows of punctures 

 feebly impressed; intervals nearly flat, the fourth a little prominent at 

 the base, the sixth finely carinate nearly to the tip. Beneath coarsely, 

 rather densely scabrous-punctate, except the abdomen, which is less 

 roughly sculptured, especially posteriorly. 

 Length, 2-2.4 mm. 



Described from nine examples taken in a small 

 mountain stream near Pasadena. 



This is the first species of the genus to be reported 

 from the Pacific Coast; it is not closely related to any 

 of the eastern species. 



51. Eurypogon confusus, sp. nov. 



Broader and more depressed than E. niger, brownish testaceous through- 

 out, shining; pubescence yellowish, inclined backward on the elytra and 

 forward on the thorax. Head sparsely, finely punctate. Antennae slender, 

 reaching slightly beyond the middle of the elytra, second joint a little 

 more than half as long as the third, the latter nearly as long as the 

 fourth; joints four to eleven subequal. Prothorax twice as wide as long, 

 sides nearly parallel for a short distance at base, then rounded and 

 rather strongly convergent to apical angles; punctuation fine, the punc- 

 tures quite uniformly distributed and separated by from two to three 

 times their own diameters; disk with two small impressions, about as 

 distant from each other as from the side margin, and a somewhat vague 

 impression extending from the anterior angles obliquely inward toward 

 the discal impressions. Elytra a little wider than the thorax, sides par- 

 allel in basal three-fifths, surface faintly substriate, intervals confusedly 

 punctate, the punctures scarcely distinguishable from those of the striae.
