PHALACRID/E 63 



of five or six very thick and rather long setae; metasternal process 

 rather wide. Length 1.3-1.45 mm.; width 0.8-0.9 mm. Cali- 

 fornia (Sta. Cruz to San Diego). Six specimens. [Olibrus obtusus 

 Lee.] obtusus Lee. 



Form oblong-oval, nearly as in obtusus, rather more elongate, deeper 

 black in color, very shining, the elytra just visibly picescent; head 

 still larger, much more than half as wide as the prothorax, smooth, 

 the eyes very moderate; antennae slender, the third joint almost as 

 long as the next two, the club evidently shorter than the funicle; 

 prothorax short, much more than twice as wide as long and less than 

 two-fifths as long as the elytra, the very moderately converging sides 

 strongly arcuate; surface obsoletely micro-substrigilate; base feebly 

 margined; scutellum slightly wider than long, ogival; elytra distinctly 

 elongate, almost semicircularly rounded in nearly apical half, the 

 fine strigilato-reticulate sculpture and minute feeble punctures 

 almost as in obtusus; a number of longitudinal impressed lines are 

 evident; prosternal process rather wide, the dilated apex bearing 

 four regularly spaced, long and very stiff setae; mesosternum well 

 developed before the metasternal process; post-mesocoxal plaque 

 large, triangular, its outer oblique line straight, the inner sinuous, 

 the two not meeting behind, leaving the narrow space between them 

 undefined; hind tarsi moderate. Length 1.55 mm.; width 0.85 mm. 

 California (southern more definite locality unrecorded). A single 

 example apertus n. sp. 



18 Body minute, strongly convex, somewhat attenuate behind though 

 rather obtuse at apex; under surface testaceous, the post-sterna 

 and femora piceous; head more than half as wide as the prothorax; 

 antennae slender; prothorax more than twice as wide as long, the 

 converging sides rather strongly arcuate, the base finely margined 

 medially; scutellum reticulate, unusually transverse, nearly twice 

 as wide as long, ogival; elytra slightly longer than wide, evenly 

 parabolic in outline, bright rufous in color, sometimes clouded 

 posteriorly and, in one example, blackish-piceous throughout, prob- 

 ably because of accidental discoloration; micro-reticulation feeble, 

 rather coarse, obsolescent basally; punctures of the series very 

 minute and feeble, the stria not very coarse but impressed; prosternal 

 process with four or five very long setae. Length 0.95-1.1 mm.; 

 width 0.55-0.65 mm. California (Los Angeles Co.). Ten ex- 

 amples apparently all females. [Eustilbus notabilis Fall]. 



notabilis Fall 



19 Body broadly, evenly elliptic, very convex and shining, clear tes- 

 taceous throughout; head rather more than half as wide as the 

 prothorax, the minute hairs borne by the remote punctules evident; 

 antennae rather stout, the first joint of the club not as long as wide, 

 the second transverse; prothorax scarcely -twice as wide as long, 

 minutely margined at base medially, smooth and not at all reticulate, 

 the punctures very minute; scutellum triangular, wider than long; 

 elytra as long as wide, rounded broadly, the sides becoming parallel 

 only near the base, the stria rather fine but distinct; surface with 

 moderately fine reticulation in transverse wavy series, obsolete
