164 MEMOIRS ON THE COLEOPTERA. 



wide as the first and a little shorter than the two preceding combined. Length 

 1.3 mm.; width 0.35 mm. California (Pomona, Los Angeles Co.)/ Fall. 



The rather long antennee, which are slender basally and some- 

 what rapidly incrassate and notably heavy apically, rather large 

 prothorax, evidently narrowing from base to apex and the paler 

 coloration will readily serve to identify this small species. 



Colpodota laxella n. sp. Broad and stout anteriorly, sharply attenuated 

 posteriorly, rather shining, piceous-brown in color, the abdomen but slightly 

 darker, the fine punctures dense and more asperate on the dullish elytra, 

 which are very slightly paler, the legs pale; head moderate, convex, wider 

 than long, parallel at the sides, the eyes at evidently less than their own 

 length from the base; antennae rather long, moderately stout, feebly incras- 

 sate, blackish throughout, the second joint slightly longer than the first but 

 not so thick and barely perceptibly longer than the third, the fourth feebly 

 obtrapezoidal and nearly as long as wide, the outer joints not increasing 

 perceptibly in size, slightly transverse, the last pointed, as long as the two 

 preceding; prothorax large and strongly transverse, much rounded at base, 

 the sides rounded and very strongly converging from the rounded basal angles 

 to the apex, unimpressed, much wider than the head, wider than the base 

 and fully as wide as the apex of the elytra, the latter well developed, with 

 evidently diverging sides, the suture about a third longer than the prothorax; 

 abdomen much narrower than the elytra, rather long, gradually tapering, 

 the fifth tergite three-fifths as wide as the first and not quite as long as the 

 two preceding combined. Length 1.45 mm.; width 0.45 mm. California 

 (Sta. Cruz). 



To be recognized by the rather stout form, slender tapering 

 abdomen and broad prothorax, which is much narrowed from the 

 rather prominent though rounded basal angles to the apex. 



Colpodota fortuita n. sp. Rather stout, unusually convex, subalutaceous, 

 the elytra dull, the punctures minute and asperate, close, fine but unusually 

 and conspicuously dense on the abdomen, which is alutaceous in lustre; color 

 dark rufo-piceous, the head black, the elytra not paler and the abdomen 

 with an indefinite black subapical cloud, the legs pale testaceous; pubescence 

 rather dense and very fine; head rather large, strongly transverse, feebly 

 dilated basally, the eyes at somewhat more than their own length from the 

 base; antenna? rather short, pale piceo-testaceous, somewhat clearer basally, 

 evidently incrassate distally, the second joint longer but thinner than the 

 first and also notably longer than the third, the fourth obtrapezoidal, dis- 

 tinctly wider than long, the outer joints slightly transverse, the last pointed, 

 as long as the two preceding; prothorax rather large, transverse, convex, 

 subparallel and evenly rounded at the sides, rounded at base, much wider 

 than the head, wider than the base and fully as wide as the apex of the elytra, 

 with a rounded and very feeble basal impression; elytra large, moderately 

 abbreviated, with only slightly diverging sides, the apices transverse but 

 deeply and rather narrowly sinuate externally, the suture fully a fourth longer
