22O MEMOIRS ON THE COLEOPTERA 



in this group of genera and nearly flat; the slender tarsi are almost 

 as in the preceding genus, the first joint of the posterior not as long 

 as the next two; the middle coxae are contiguous, separated beneath 

 by a fine sunken lamina, the mesosternal process short, very finely 

 acute at tip and separated by an extended interval from the small 

 but almost equilatero-triangular metasternal projection. In com- 

 mon with the other genera of this group, the hypomera are only 

 moderately inflexed and are wholly visible from the sides. The 

 first species described below has the elytra notably shorter than 

 the others: 



Alisalia brevipennis n. sp. Parallel, rather convex, strongly shining, 

 pale testaceous, the head and an indefinite subapical abdominal cloud 

 dusky; punctures very fine, not close, the pubescence pale, short but 

 inclined, rather coarse and sparse; head subtriangular, with rounded 

 sides, as long as wide, not quite as wide as the prothorax, the eyes small, 

 not prominent, anterior: antennae short, dusky, paler basally, the second 

 joint scarcely shorter and slightly thinner than the first, as long as the 

 next two, third one-half longer than wide, obconic, fourth wider, trans- 

 verse, fifth still wider and more transverse, fifth to tip subequal in width 

 and stout, the tenth more than twice as wide as long, the last obtusely 

 ogival, rather longer than the two preceding; prothorax transverse, two- 

 fifths wider than long, slightly widest before the middle, the sides broadly 

 arcuate, the basal angles very obtuse, rounded, the surface wholly un- 

 impressed; elytra short, transverse, equal in width to the prothorax, the 

 suture barely as long as the latter and decidedly shorter than the elytral 

 flanks; abdomen long, parallel, as wide as the elytra, the fifth tergite 

 about a third longer than the fourth. Length 1.25 mm.; width 0.18 mm.

Sexual characters are not apparent among the numerous ex- 

 amples taken some years ago, probably in fungous earth; the indi- 

 viduals are quite uniform in size. 



Alisalia parallela n. sp. Parallel, compact, moderately convex and 

 shining, testaceous, the head blackish, the abdomen with a large suffused 

 and feebly dusky subapical area, the elytra somewhat dusky though more 

 yellowish; punctures very fine and rather dense, sparser on the abdomen, 

 the reticulation of which is remarkably coarse basally but smaller and 

 stronger apically, where the punctures become sparser though sharply 

 asperulate; pubescence short, coarse, decumbent, pale; head much wider 

 than long, five-sixths as wide as the prothorax, feebly broadening basally, 

 the eyes feebly convex, at one-half more than their own length from the 

 base; antennae nearly as in the preceding but less thick and with the third 

 joint twice as long as wide, the tenth twice as wide as long, the last much 

 longer than the two preceding; prothorax two-fifths wider than long, 

 nearly as in the preceding, the basal angles more distinct, the base sub-
