68 MEMOIRS ON THE COLEOPTERA 



ceding, the tarsi notably long and slender, with the joints of the 

 usual proportion, four-fifths as long as the tibiae, coarsely pubescent 

 beneath. Length 1.15-1.3 mm.; width 0.68-0.8 mm. Texas 

 (Austin and from an unrecorded locality). Eight examples. 



modestus Csy. 



Punctures of the same series evident but smaller and less dilated, toward 

 the sides very shallow and scratch-like, as usual in this section. . .28 



28 Body not very narrowly oval, obscure piceo-rufous; head barely at 

 all over half as wide as the prothorax, minutely, indistinctly punctu- 

 late; antennae shorter than usual, the third joint shorter than the 

 next two combined, the fourth shorter than the fifth, the club rather 

 evidently shorter than the funicle, the tenth joint wider than long; 

 prothorax not distinctly more than twice as wide as long, of the usual 

 form, the converging sides arcuate; base finely margined medially; 

 scutellum triangular, but little wider than long; elytra only very 

 little longer than wide, but little more than twice as long as the pro- 

 thorax, broadly rounded at tip, the sides more parallel basally; 

 micro-reticulation rather coarse but very feeble, scarcely disposed in 

 wavy lines; prosternal process with six long stiff subporrect setae; 

 mesosternum rapidly declivous from the tip of the metasternum and 

 with several moderate setae; plaque behind the middle coxae not very 

 sharply defined but apparently angulate, as usual in Stilbus; legs 

 nearly as in the preceding species. Length 1.2-1.25 mm.; width 

 0.65-0.7 mm. District of Columbia. Three examples. [Olibriis 

 pusillus Lee.] pusillus Lee. 



Body more oblong, very convex and polished, brighter rufous; head evi- 

 dently more than half as wide as the prothorax, the punctulation 

 somewhat obvious; antennae rather more slender than in pusillus; 

 prothorax shorter than in the preceding, much more than twice as 

 wide as long and about three-sevenths as long as the elytra, feebly 

 margined medially at base, the converging sides evenly arcuate; 

 scutellum sharply ogival, one-half wider than long; elytra distinctly 

 longer than wide, of peculiar outline, the sides feebly converging and 

 barely at all arcuate for two-thirds, then rather rapidly, very broadly 

 rounded through the apex; micro-reticulation somewhat coarse but 

 very feeble, the wavy lines moderately evident; prosternal process 

 with five long stiff setae; mesosternum not very rapidly declivous, 

 convex; hind tibiae not very stout, the tarsi slender, but, as usual in 

 this group, with the second joint less than twice as long as the first; 

 basal segment of the abdomen equal to the next two, the apex rather 

 acute. Length i.o mm.; width 0.6 mm. Florida (Capron), 

 Schwarz. [S. pusillus Csy. nee Lee., pars, olim]. .abbreviates n. sp. 



Body narrower, more evenly elongate-elliptical, bright brownish-rufous; 

 head fully three-fifths as wide as the prothorax, the punctulation 

 barely evident; antennae with the third joint unusually short, in- 

 flated apically, scarcely more than twice as long as wide and shorter 

 than the next two, the fourth slightly shorter than the fifth; club 

 rather evidently longer than the funicle; prothorax but slightly 

 more than twice as wide as long, the sides unusually feebly 

 converging, moderately arcuate, the basal marginal stria feeble;
