NORTH AMERICAN COLEOPTERA. 98 



tlie body; first joint very moderate, second'smaller, tliird to eightli still smaller 

 and sliglitly elongated, sub-equal ; ninth to eleventh longer and broader, but not 

 appreciably flattened; all densely pubescent. Length 1.4 — 1.7 mm. 



Plate VII, Fig. 7. 



This is also a cosmopolitan species. 



22. li. pilbesceus n. sp. — Form moderately elongated and very depressed ; 

 sides paralk'l. Punctures on head and prothorax rather close and fine; elytra ob- 

 scurely and closely striate ; entire surfiice covered with rather dense pubescence, 

 which is somewhat long and fine, that .on the elytra is arranged in exceedingly 

 approximate rows. Color dark testaceous ; elytra, legs and tips of antennae much 

 paler. Head sub-triangular, rather small; front of epistoma slightly emarginate; 

 sides of same deeply and acutely excavated ; eyes rather large, a little advanced 

 and not prominent; median furrow well developed. Prothorax a little wider than 

 head, broader than long and very slightly narrowed behind; lateral striae well 

 marked ; sides almost straight ; anterior angles rather acute ; posterior angles right. 

 Scutellum small, transverse and evenly rounded behind. Elytra broader than 

 prothorax, nearly twice as long as the head and prothorax together, obtusely 

 rounded behind, and entire ; sides parallel and .almost straight. Abdominal seg- 

 ments sub-equal. Antennae about three-fourths as long as the body ; first joint 

 elongated, second smaller, a little elongated, third to eighth yet narrower, elon- 

 gated and sub-equal, ninth to eleventh longer, but no wider, sub-equal and cylin- 

 drical : all densely pubescent. Length 1.5 — 1.9 mm.

The pubescence of the elytra resembles somewhat that of Horni, but 

 is longer. California. 



23. Ij. trunctttlis n. sp. — Form elongated, moderately depressed ; sides par- 

 allel. Punctures of prothorax coarse and moderately close, those of head rather 

 finer; elytra striate, striae punctate. Pubescence long and plentiful, that on elytra 

 arranged in rows. Head moderate, very declivous in front of the line joining the 

 bases of the antennae; median line visible; eyes very small, advanced and eon- 

 vex. Prothorax as wide as the head ; very slightly broader than long and nar- 

 rowed behind ; lateral striae well developod ; anterior and posterior angles acute. 

 Scutellum small, evenly rounded behind. Elytra one-half as long again as the 

 head and prothorax together, equal in width to the latter; entire and obtusely 

 truncated behind, bordered ; sides parallel, nearly straight. First three abdominal 

 segments equal, last two much shorter and sub-equal. Antennae nearly as long 

 as the entire body, first three joints moderate, slightly elongated, and decreasing 

 in size; joints four to eleven gradually increasing in length and decreasing in 

 width, density of pubescence increasing gradually toward the tip ; basal joints 

 strongly punctate. Length 1.9 mm.

One specimen, Michigan (Schwarz). 



24. Ij. pustillus (Sch(')n.) Male. — Form very moderately elongated, de- 

 pressed. Punctuation rather fine and close on prothorax, coarser on head ; elytra 

 stria^. Surface scarcely shining. Pubescence somewiiat abundant, long and fine 

 on head and prothorax, almost entirely absent on elytra. Color ferruginous, legs
