feebly biimpressed at the middle; surface deeply, transversely impressed be- 

 hind the buccal opening; mentum rather large, flat, quadrate, the apex arcu- 

 ate; ligula small, the labial palpi small, -with the first joint subcylindric and 

 longer than wide, the second smaller, oboval, slightly narrowed at base, with 

 an axial apical setigerous puncture, the seta long and arcuate; the third joint 

 projects as a minute slender cylinder forward from the apex of the third at 

 nearly right angles; maxillary cardo large, triangular, somewhat exserted, the 

 lobe small, setose; maxillary palpi large and well developed, the first joint 

 small, second obconic, twice as long as wide, third fully as long as wide, 

 slightly wider than the second, somewhat narrowed at base, fourth large, 

 oval, as long as the preceding three, fully twice as wide as the third, narrow 

 at base, compressed and more pubescent toward tip. Antennpe nearly % as 

 long as the body, the basal joint thicker, cylindric, J^ longer than wide ; sec- 

 ond narrower, oval, longer than wide; third minute, globular ; four to eight 

 equal, nearly as thick as the second, subglobular, moniliform; ninth and tenth 

 transverse; nine to eleven wider, forming a distinct club; eleventh but little 

 longer than wide, much shorter than the two preceding. Proihorax slightly 

 wider than long, widest and strongly rounded near the middle, the sides 

 strongly and subequally Convergent to apex and base, feebly sinuate toward 

 base ; apex scarcely % as wide as the base ; disk moderately convex, with a 

 large, deep and transverse foveiform impression at basal third which is 

 narrowly produced anteriorly for some distance, and a smaller pit at each side 

 near basal fourth, continued posteriorly to the base ; there is also a smaller 

 isolated nude fovea near the basal margin at lateral fourth. Elytra short and 

 transverse, only very slightly longer than the prothorax and about }4 wider, 

 the sides divergent and feebly arcuate from the just visibly exposed and ob- 

 tuse humeri ; disk completely devoid of hiimeral plica or basal impression, 

 flat, with two longitudinal impressions on each from behind the base to or 

 behind the middle, the outer near the flank and short, the other near the mid- 

 dle and becoming deep basally ; sutural stria deep, with an external fovea at 

 base. Abdomen much more than twice as long as the elytra, and, toward tip 

 very much wider, the sides nearly straight and continuing the divergence of 

 the elytral flanks, the border very wide, strongly inclined; apex abruptly nar- 

 rowed. Legs moderate in length, the femora feebly fusiform; third joint of 

 the hind tarsi twice as loug as the two basal joints combined; claws well de- 

 veloped; middle coxae separated by a narrow lamina. Length 2.65 mm.; 

 width 0.8 mm. 



Oregon (Portland). Hubbard and Schwarz. 



The type is a male, the sixth ventral segment being ainaate at 

 tip, the surface feebly impressed toward the middle, the impres- 

 sion smooth, polished and limited laterallj^ by small erect and 

 sublaminiform tubercles near the apex ; the seventh is in the form 

 of an elongate-oval, strongly convex pygidium with its posterior 

 extremity minutely foveate. I cannot perceive that the male 

 modifications in this species are at all asymmetric. This is by
