COLEOPTERA OF SOUTHERN CALIFORNIA. 219 



i6. Agathidium virile, sp, nov. 



Moderately contractile, piceous black, ajjex of elj^tra and margins of 

 thorax a little paler, legs brown. Head finely, sparsely punctate. Pro- 

 thorax less than twice as wide as long, hind angles broadly rounded, front 

 angles less broadly rounded, surface still more finely, obsoletely punctu- 

 late. Elytra longer than wide, distinctly but rather sjiarsely punctate, 

 sutural stria deeplj' impressed except toward the base; side margin when 

 viewed in i^rofile subaugularly rounded near the base. Metasternum 

 alutaceous, obsoletely punctulate, without oblique elevated ridge. Meso- 

 sternum continuous with the metasternum, carinate in front. There is 

 the usual difference in the tarsi of the sexes, and in addition the posterior 

 femora are broader and obtusely augulate near the apex in the males, and 

 in the same sex there is near the middle of the front margin of the meta- 

 sternum a transversely oval fovea bearing a tuft of erect hairs. 



Length (extended), 3 mm. 



Riverside, Pomona and Pasadena. 



This species may at once be known by the sexual 

 characters of the male. It should be placed between 

 A. calif ornicus and A. revolvens in Horn's table. 



17. Lomechusa angusta, sp. nov. 



Red-brown, parallel, much smaller and narrower than either L. cava or 

 L. montana. Upper surface, except the abdomen, minutely reticulate and 

 sparsely, finely punctate, the head and prothorax somewhat dull, the 

 elytra more shining; abdomen both above and beneath polished and 

 nearly impunctate. Pubescence very fine, short and sparse; represented 

 on the abdomen by longer erect setas, which on the dorsal surface are 

 arranged in a more or less regular transverse line on each segment, but 

 are longer and more numerous beneath. Front concave; eyes situated at 

 more than their own length from the hind margin of the head. Antennae 

 a little longer than half the body, the intermediate joints about twice as 

 long as wide; terminal joint just visibly longer than the two preceding 

 united. Prothorax nearly twice as wide as long, broadly emarginate in 

 front throughout the width of the head, the front angles broadly rounding 

 into the sides, which are feebly sinuate behind the middle, and thence 

 slightly divergent to the hind angles, the latter nearly right and very 

 narrowly rounded; base rather strongly arcuate at middle, sinuate later- 

 ally, side margins broadly reflexed. Elytra slightly wider than the pro- 

 thorax, proportioned as in our other species. Abdomen and legs also as 

 usual in the genus. 



Length, 3.25 mm. 



Pasadena and Redondo.
