9 Onycliobaris aildax n. sp. — Oblong, strongly convex, shining, tlie 

 elytra feebly alataceous, brownish rufous throughout, the elytra blackish, 

 setse very small, distant and forming even single lines on the elytra. Head 

 toward apex and beak finely but densely punctate, the latter moderately 

 slender, evenly, somewhat strongly arcuate and rather longer than the pro- 

 thorax ; antennje slender, second funicular joint but little longer than the 

 third. Prothorax about one-fourth wider than long, the sides straight and 

 somewliat divergent from the base to apical fourth, then strongly rounded and 

 subprominent, thence very strongly convergent to the apex which is minutely 

 and visibly constricted ; base transverse, the median lobe rather narrow but 

 prominent, rounded, constituting less than one- third of the width ; disk with 

 but the feeblest traces of a short median line, the punctures very deep, mode- 

 rately small, one-third as wide as the scutellum, very dense, almost in mutual 

 contact but circular and not polygonally crowded. Scutellum moderate, trans- 

 verse. Elytra about one-fifth longer than wide, two-thirds longer than the 

 prothorax, and, at the small feebly tumid humeri, but just visibly wider 

 than tiie disk of the latter ; sides for a short distance behind the humeri 

 parallel, then elliptically rounded through the apex ; disk with rather nar- 

 row, deep and finely, remotely but distinctly punctate grooves, the intervals 

 flat, subequal, about twice as wide as tlie goooves, each with a single series of 

 somewhat small, feeble, rather remote and subtransverse punctures, slightly 

 confused toward base especially on the fifth. Abdomen rather finely, not densely 

 punctured. Length 3.0 mm. ; width 1.4 mm. 



California (southern). 



A small and easily recognizable species, having the prothorax 

 rather wider at apical fourth than at base, and with the sides straight. 

 It is also somewhat aberrant in coloration. 



10 Onycliolbaris Stictica n. sp. — Oblong, not very robust, strongly 

 convex, black, the head and beak feebly rufescent, the legs paler, rufous : 

 integuments polished, moderately densely sculptured. Head finely, sparsely 

 punctured, the punctuation obsolete toward base, the feeble transverse im- 

 pression broadly impunctate and polished ; beak moderately stout, rather 

 feebly, evenly arcuate, fully as long as the prothorax, strongly, densely punc- 

 tate, with a narrow impunctate and subcarinate median line ; antennse normal, 

 the second funicular joint slightly longer than the third. Prothorax: rather 

 elongate, scarcely one-fourth wider than long, the sides parallel and nearly 

 straight to apical fourth, then broadly, evenly rounded and strongly conver- 

 gent to the apex, which is quite distinctly constricted ; base transverse, the 

 median lobe very broad, distinct ; disk without distinct trace of median line ; 

 punctures rather small, circular, deep, dense but not quite in actual contact 

 and scarcely one-fourth as wide as the scutellum. Scutellum well developed, 

 transverse. Elytra one-fifth longer than wide, one-half longer than the pro- 

 thorax, at the feebly tumid humeri but just visibly wider than the latter, the 

 sides thence feebly convergent and nearly straight to the apex, the latter semi- 

 circularly rounded ; disk with rather coarse abrupt and moderately deep
