DESCRIPTION OF NEW SPECIES 163 



strongly arcuate in posterior half, thence rather straight and somewhat 

 strongly convergent to apex as viewed from above, serrules small and 

 subacute, fimbriae cinereous and moderate in length; apical angles 

 obtusely rounded; base broadly arcuate, feebly sinuate laterally; basal 

 angles represented by a denticle, otherwise rounded; disk evenly and 

 moderately convex posteriorly, arcuately and strongly declivous antero- 

 laterally ; punctures in the central area moderate in size and separated by 

 a distance equal to about one or two times their diameter, intervals slightly 

 rugulose, or very obsoletely indentate, laterally not very coarsely 

 reticulato-punctate. 



Elytra oblong, about twice as long as wide, rather evenly convex 

 from side to side ; disk moderately closely punctate, punctures not strongly 

 outlined, separated by a distance equal to one or two times their diameter, 

 surface somewhat feebly transversely rugose; punctures finer and more 

 widely spaced toward apex, the latter evenly rounded. 



Abdomen finely and densely punctured ; fifth ventral segment modified 

 on the disk in the male. 



Legs moderate in length and stoutness ; metafemora somewhat con- 

 stricted at base. 



Male. Parallel, slightly elongate. Fifth ventral distinctly sinuate, 

 slightly blackened on the impressed area, hairs pale and normal elsewhere. 



Female unknown. 



Measurements. Length, 2.6 mm. ; width, .9 mm. 



Holotype, male, in my own collection. 



Type locality. San Diego, California, without other data. Collected 

 by Mr. O. N. Sanford. 



Occident is quite distinct in its feebly marked elytral maculation, 

 rufous antennae, tibiae and tarsi, modified fifth ventral segment of the 

 abdomen, ashy pubescence and several other minor differences. 



Listrus angulatus, new species. Form oblong-ovate, about three 

 times as long as wide and moderately convex. Color black, feebly 

 shining, with a very slight aeneous lustre anteriorly ; tarsi and distal part 

 of the tibiae dark rufo-piceous ; antennae nigro-piceous throughout. 



Pubescence abundant, conspicuous, moderate in length and coarse- 

 ness, recumbent, longer on the under surface of the body, plumbeo- 

 cinereous in color and somewhat silvery on oblique inspection. The dark 

 brownish hairs are arranged in more or less discrete maculae as follows : 

 Basal maculae obsolete, or a small humeral and a parascutellar which in 

 some instances coalesce on each elytron remaining rather widely inter- 

 rupted at the scutellum ; post-basal macula variable in size at middle of 

 each elytron ; a submedian fascia which is very narrow and zig-zag, or
