COLEOPTERA OF SOUTHERN CALIFORNIA. 225 



In L. texanus, which occurs at Yuma, the sixth ventral 

 has a deeper emargination, which is rounded at bottom 

 and with nearly parallel sides. 



27. Leptorus longipennis, sp. nov. 



Very slender, piceous, head and thorax dark rufous, legs and antennas 

 paler; surface more shining than in L. calif ornicus. Sides of thorax 

 slightly convergent toward the base; elytra fully one-third longer than the 

 thorax. Punctuation much as in L. californicus, that of the head a little 

 coarser above and distinctly so beneath. 



Length, 2.2 mm. 



Described from a single female specimen taken at 

 Pomona. 



This is the first species of the genus known to occur 

 west of the mountains. It is at once separable from 

 any species known to me by the unusual disparity in the 

 length of the thorax and elytra, and by the decidedly 

 stronger punctuation of the lower surface of the head. 



28. Scopseus armiger, sp. nov. 



In most features of size, form, and sculpture, and especially in the male 

 sexual characters, this species is very similar to the eastern S. dentiger.* 

 It is a little more slender, the hind angles of the head less broadly 

 rounded, the prothorax distinctly narrower than the elytra, the latter com- 

 paratively more elongate than in S. dentiger; the legs are brown. The 

 male characters are substantially the same, with the following exceptions: 

 The emargination of the sixth ventral is a little less broadly rounded at 

 its apex, the inner sinuate margin of the posterior femora is a little more 

 strongly serrate, and the hind tibiae are not serrate internally. 



The only specimen seen by me is a male taken at 

 Pomona. 



29. Stilicus occiduus, sp. nov. 



Form and size the same as that of S. angularis, color more nearly pice- 

 ous. Head above rather finely and densely punctate, not rugose; below, 

 rufopiceous, polished, rather sparsely punctate; sides behind the eyes a
