68 MEMOIRS ON THE COLEOPTERA. 



Tinotus coelebs n. sp. Stout, feebly, the abdomen more evidently, 

 shining, black, the elytra faintly rufescent, the legs pale; sculpture and 

 vestiture nearly as in imbricatus, except that the coarse asperate punc- 

 tures of the elytra become notably finer and closer toward the suture than 

 elsewhere; head nearly similar though somewhat larger, the antennae also 

 nearly similar but with the third joint much more evidently longer than 

 the second, the fourth as long as wide, subparallel, the outer joints three- 

 fourths wider than long; prothorax three-fourths wider than long, the sides 

 strongly rounded, more converging anteriorly, the base rounded, the 

 surface (cf 1 ) with a large and broadly oval impression extending from 

 base to near the apex, the bottom of which is more finely chagrined; 

 elytra moderately short, the suture fully as long as the prothorax, the 

 oblique sides of the apex broadly sinuate, the flanks, as usual, much longer 

 than the suture; abdomen broad, with thick margins, about as wide 

 as the elytra, gradually and very feebly narrowed and with nearly straight 

 sides to the fifth tergite, which is four-fifths as wide as the base and a third 

 longer than the fourth, the sixth ventral plate arcuato-truncate, the 

 truncature having a dense porrect fringe of coarse pale semi-membran- 

 ous hairs. Length 2.4 mm.; width 0.78 mm. Texas (Austin). 



Differs from the two preceding in its much stouter form, rather 

 larger size and in having the elytral punctures more evidently smal- 

 ler and closer toward the suture. The male type differs from that 

 sex of imbricatus, also, in having a relatively more elongate third 

 antennal joint and in the larger and less transverse prothorax. 



Tinotus fusinus n. sp. Rather fusiform, somewhat shining, the ab- 

 domen strongly so, deep black in color, the elytra not evidently at all 

 paler, the legs dark brown; sculpture nearly as in the preceding species 

 but rather finer, the punctures of the abdomen sparser, with the im- 

 bricating lines much feebler; head, eyes and antennae nearly as in im- 

 bricatus; prothorax a little less transverse, evidently less than twice 

 as wide as long, the sides strongly rounded and more converging ante- 

 riorly, becoming parallel basally; elytra short, apparently somewhat 

 wider than the prothorax except at base, the sides slightly arcuate 

 basally, the suture barely as long as the pronotum; abdomen broad, at 

 base subequal in width to the elytra, thence evenly but feebly tapering, 

 with nearly straight sides and somewhat thin margins, to the fifth 

 tergite, which is rather more than three-fourths as wide as the base, 

 the portions behind this tergite broadly subtubulate (cf 1 ), as in the other 

 species. Length 1.6 mm.; width 0.56 mm. Tennessee (Nashville). 



This species, as represented by the single male before me, is allied 

 rather closely to imbricatus, differing apparently in its less transverse 

 and more parallel prothorax, the large oval depression of the male 

 having its pubescence very much coarser and less sericeous, though 

 similarly denser, paler and more conspicuous than that of the
