in its more finely and closely imbricated elytra, and still larger and 

 longer but more gradually formed antennal club. Two specimens. 



S. OTiforiue n. sp. — Broadly oval, convex, polislied, black, the legs 

 piceo-testaceous ; antennae flavate ; punctures of the head and pronotum fine, 

 moderately close, even ; elytra and abdomen with imbricate sculpture ; pubes- 

 cence moderate in length, fuscous, rather conspicuous. Head vertical, not 

 visible from above, the eyes large, attaining the base ; antennae short, one- 

 half longer than the head, the second joint longer than the iirst and longer 

 than the next two combined, third longer than the fourth and nearly twice 

 as long as wide, three to seven subequal in width, the latter somewhat trans- 

 verse, club abrupt, parallel, loose, the ninth joint one-half wider than long. 

 Prothorax small, about twice as wide as long ; base strongly arcuate ; apical 

 angles deflexed and right, narrowly rounded ; basal almost obliterated ; disk 

 evenly convex. Elytra together broadly emarginate at base and equally 

 broadly, triangularly emarginate at apex, at apical third much wider than the 

 prothorax, one-third longer ; sides strongly arcuate toward base, continuous 

 in curvature with the prothorax. Abdomen, when contracted, a little wider 

 than long, about as long as the elytra, subcontinuous in outline with the 

 latter, conical, the sides nearly straight ; fifth segment as long as the two 

 preceding together. Legs slender, the posterior tarsi much shorter than the 

 tibiae. Length 0.75 mm.; width 0.5 mm. 



California (Los Angeles Co.). 



Differs from the preceding two species in its more evenly elliptical 

 outline, more abruptly formed antennal club and longer fifth ventral 

 segment. 



Note. 



The species described by Say as Aleochara simplicicollis (Trans. Am. Phil. 

 8oc., VI, p. 155), is identical with Microglotta suturalis Sahib. 



OXYTELINI. 



OXYTELIJS Grav. 



Considering the general homogeneity of facies in Oxytelus, there 

 is an unusual amount of variation in the structure of important 

 organs, such as the mentum, and especially a very great amount of 

 diversity in the male sexual modifications ; these may manifest 

 themselves at either end of the body, sometimes virtually at the 

 head only, in other species at the abdominal apex, but occasionally 

 also quite noticeably at both extremities. The females are often 

 very similar among themselves, and it is frequently almost impos-
