pale in color; head much wider than long, three-fifths as wide as the 

 prothorax, the eyes rather prominent, at three-fifths their own length 

 from the base, the carinae fine, entire; antennae pale ochreo-flavate 

 throughout, rather short and slender, gradually very feebly incrassate, 

 the first three joints diminishing regularly and moderately in length, 

 the third very evenly obconical and slender, not in the least constricted 

 basally, four to six a little longer than wide, tenth slightly wider than long, 

 the last as long as the two preceding; prothorax widest just behind the 

 middle, fully three-fourths wider than long, the sides strongly and 

 subevenly rounded, somewhat more converging anteriorly than poste- 

 riorly, wholly unimpressed; elytra moderately transverse, with slightly 

 diverging, feebly and evenly arcuate sides, at apex as wide as the pro- 

 thorax, at base slightly narrower, the suture fully a fourth longer, the 

 apices rather deeply sinuate laterally; abdomen at base only very 

 slightly narrower than the elytra, evenly and feebly tapering, with nearly 

 straight sides throughout, the fifth tergite equal in length to the fourth 

 and four-fifths as wide as the first. Length 1.8 mm.; width 0.45 mm.

Differs from cupiens principally in its more parallel and less 

 fusoid form, larger head, much less strongly tapering abdomen and 

 in its paler coloration, with the large and more diffused black cloud 

 of cupiens virtually confined to the fourth tergite. 



Colpodota Rey. 



The following species has an exceptional form among the Cali- 

 fornia species, but may be placed near laxella in the arrangement 

 given in my previous paper: 



Colpodota pupilla n. sp. Rather stout and strongly fusoid, moderately 

 convex, subalutaceous, finely, closely, asperulately punctate, the abdomen 

 more shining and with the fine asperate punctures well spaced through- 

 out; color dark piceous-brown, the elytra but just visibly paler, the legs 

 pale brownish-flavate; pubescence rather short, abundant and distinct; 

 head notably small, three-fifths as wide as the prothorax, a little wider 

 than long, the eyes slightly prominent, at somewhat more than their own 

 length from the base, the tempora slightly fuller than the eyes, broadly 

 rounded, gradually more converging basally, the carinae entire; antennae 

 rather heavy, blackish-piceous throughout, gradually and evidently 

 incrassate, slightly longer than the head and prothorax, the first three 

 joints equal in length, the first stoutest, four to ten of similar length, 

 passing from as long as wide to a third wider than long, the last ogival, 

 as long as the two preceding; prothorax one-half wider than long, widest 

 basally, the sides thence strongly converging and broadly arcuate to the 

 apex, which is two-thirds as wide as the base, the latter rounded, the 

 angles subobliterated, the surface unimpressed; elytra transverse, with 

 very feebly diverging sides, at ba.se not quite as wide as the prothorax, 

 the suture equal in length to the latter; abdomen at base distinctly
