222 MEMOIRS ON THE COLEOPTERA 



as long as wide, only just visibly narrower than the prothorax, oval, 

 widest before the base, the sides broadly rounded; eyes small, not promi- 

 nent, at twice their length from the base; antenna? notably short, dusky, 

 paler basally, the second joint distinctly shorter and thinner than the 

 first, as long as the next two, the third obconic, but little longer than wide, 

 fourth very transverse, fourth to tip gradually and rather rapidly wider, 

 becoming notably stout at tip, the very transverse outer joints more than 

 twice as wide as long; prothorax nearly as in the preceding but only about 

 a third wider than long; elytra less developed, subparallel, scarcely visibly 

 wider, the suture but little more than a fifth longer, than the prothorax; 

 abdomen barely narrower than the elytra, parallel, the fifth tergite one- 

 half longer than the fourth. Length 0.9 mm.; width 0.18 mm. North 

 Carolina (locality not recorded). 



The single type of this species, the smallest known to me, is a 

 female; it differs from the female of testacea in its more slender 

 parallel form, shorter, more gradually incrassate antennse distally, 

 smaller elytra and in having the broad trapezoidal sixth ventral 

 plate, not broadly and evenly rounded at tip, but broadly and 

 obtusely angulate; the abdomen seems to be a little wider at the 

 apex of the fifth tergite than at base. 



Alisalia delicata n. sp. Very slender, subparallel, shining, testaceous, 

 the head dark, the subapical abdominal cloud small and barely distin- 

 guishable; punctures very fine, not dense; head nearly as long as wide, 

 barely at all narrower than the prothorax, gradually and moderately 

 inflated to the unusually broadly rounded basal angles, the eyes at nearly 

 twice their length from the base; antennae as usual in general structure 

 but with the second joint not quite as long as the next two, third more 

 than one-half longer than wide, subpedunculate at base, fourth and 

 following strongly transverse, fourth to seventh gradually wider, seven, 

 to tip subequal in width and moderately stout, the last obtuse, much 

 longer than the two preceding; prothorax of the usual form, two-fifths 

 wider than long, a little wider before the middle than at base; elytra 

 shorter than wide, a fourth wider and fully two-fifths longer than the 

 prothorax; abdomen slender, much narrower than the elytra, the fifth 

 tergite (cf) not quite one-half longer than the fourth and with scattered 

 asperities. Length 1.5 mm.; width 0.2 mm. Colorado (Canon City), 

 Wickham. 



The single male type has the sixth ventral plate broadly, subevenly 

 arcuate at tip. This species is much more slender than testacea 

 and with relatively less developed head and prothorax. The type 

 is gummed with a very small pale flavate ant. 



Alisalia austiniana n. sp.- Slender, feebly convex, rather shining, pale 

 brownish-testaceous, the abdomen redder, the head but slightly more 

 dusky; punctures very fine, close, sparser on the abdomen; pubescence
