232 MEMOIRS ON THE COLEOPTERA 



blackish, pale basally, the seventh joint strongly transverse, the club 

 abrupt, the eighth and ninth joints slightly increasing, unusually short 

 and transverse, of equal length, the tenth somewhat longer than the two 

 preceding; prothorax short, much more than twice as wide as long, with 

 the rounded base closely applied to the elytra throughout the width and 

 with rather feebly converging but strongly arcuate sides; elytra moder- 

 ately transverse, with feebly arcuate sides, posteriorly but just visibly 

 wider, the suture nearly one-half longer, than the prothorax; abdomen 

 only very slightly narrower than the elytra, the sides straight and very 

 nearly parallel, only just visibly converging from base to apex. Length 

 0.75 mm.; width 0.24 mm. Texas (Austin). 



Differs from the preceding in its smaller size, narrower form, 

 more parallel abdomen, shorter antennae, with more transverse 

 two basal joints of the club, and in several other features. 



The two following species are allied more closely to the European 

 pusillima Grav.: 



Oligota parallela n. sp. Rather stout, parallel, shining, deep black 

 throughout, the abdomen pallescent at apex, the legs pale; punctures 

 anteriorly very minute, not close, coarsely but not strongly imbricate 

 on the elytra, the abdomen imbricate as usual ; pubescence long and rather 

 coarse but sparse and decumbent, palish; head rather large, fully two- 

 thirds as wide as the prothorax, the antennae unusually short and thick, 

 black, piceous basally, barely one-half longer than the head, the third 

 joint but little longer than wide, the club somewhat gradual in formation, 

 the seventh joint larger than usual, transverse, the first two joints of 

 the club strongly transverse; prothorax fully twice as wide as long, 

 notably convex, the sides only very feebly convergent and broadly 

 arcuate from base to apex; elytra subparallel, rather transverse, equal 

 in width to the prothorax, the suture about a third longer; abdomen equal 

 in width to the elytra, parallel, only just visibly narrowing at the apex, 

 the sides very feebly arcuate. Length 0.8 mm.; width 0.28 mm. New 

 York (Willets Point, Long Island). 



Very distinct from pusillima and the following species in its 

 stouter form and more developed elytra, but the general parallel 

 linear outline is the same. 



Oligota linearis n. sp. Rather slender, parallel, convex, black, the 

 abdomen pallescent at apex, the legs piceous; punctures very minute, 

 nearly simple, rather close-set, the elytral sculpture imbricate; pubescence 

 rather short, decumbent and finer than usual, only slightly pale, incon- 

 spicuous though not very sparse; head fully two-thirds as wide as the 

 prothorax, the antennae blackish, moderately short, of the usual form, 

 the funicle very slender, the third joint nearly twice as long as wide, 

 seventh transverse though less than twice as thick as the third, three- 

 fifths as wide as the eighth, the club stout, abruptly formed, its two basal 

 joints increasing, both strongly transverse, the last obtusely ovoidal,
