oni'-liuir widiT than Ioiik. one-tliii'd wider at the hasc tliaii at tlie a]K'X. well 

 roundefl on the sides and strongly constricted at the ajiex, ocular lobes broad, not 

 prominent, apical margin not much elevated, lateral tubercles somewhat trans- 

 verse, small, acute, channel linear, interrupted at the middle, superficial, except 

 at the base, disc evenly and rather finely punctured, basal margin nearly straight 

 each side ; scutel scarcely visible. Elytra one-fourth wider at tlie base than the 

 prothorax, longer than wide, feebly rounded on the sides, the latter subparallel 

 for three-fourths their length, then obliquely rounded to the apex, striie fine, 

 punctures not clo.sely approximate, interspaces flattened, rugose, posterior callus 

 with a few very minute, at^ute granules; pygidium closely punctured, underside 

 not densely clothed with small, whitish scales: femora slender, niutic. tibiie sub- 

 parallel, a little wider towards the apex, tarsi rather slender, first two joints a 

 little elongate, third broadly bilobed. lobes long, fourth joint slender, projecting 

 about the length of the preceding joint, claws simple, slender, divergent. Length 

 2.0 mm. ; 0.08 inch. 



H(xb. — District of Coliiiul)i:i. 



A female specinieii in Mr. Ulke's coll., closely related to the next. 

 The in.-^ertiou of the antenuio beyond the middle of the rostrum in 

 the female is worthy of note. 



V, moro^iis n. sj). — Very closely resembles rnfipex, with which it agrees in 

 all particulars, except the following: Black, tibite and tarsi piceous. aiitennic red- 

 dish brown, inserted two-fifths from the base ( 9), joints 1-3 of funicle eloiigate, 

 .slender, 4-fi short : prothorax very densely punctured in its basal half. Elytra 

 shining; tibiie slender, jiarallel, not at all widened to the apex, fourth tjirssil joint 

 shorter, projecting less than the length of the third joint. Length 2.2.^ mm.; 

 0.09 inch. 



Hdh. — Virginia. 



A female specimen in ^Nlr. Bolter's coll. It is with some hesitation 

 that I consider this as distinct from enjtliropus. The single s[)ecimen 

 is very nuich abraded, but what is left of the pubescence would seem 

 to indicate that it is finer than in rvfipes, the hair-like scales are 

 bistriate under high amplication, a character not ob.^erved in nijipes. 

 The difference in the insertion of antennae is very marked, both type 

 specimens being females, likewise the relative length of the fourth 

 tarsal joint. 



C atrioulllS n. sj). — Oblong oval, black, antenna* testaceous, very thinly 

 clothed with a tine, scale-like pubescence, scales a little larger on the undei"side 

 than above. Beak slender, cylindrical, regularly curved, finely striate and punc- 

 tured towards the base, .somewhat shining and more remotely punctulate towards 

 the apex; antennse slender, inserted at the middle, funicle (5-jointed, first joint 

 more robust, second a little longer than the tliird, clava rather large, oval elliptic, 

 dusky. Head rather wider, feebly convex, very closely punctured ; prothorax a 

 little wider than long, broadly rounded on the sides, rather broadly, but not 

 strongly constricted at the apex, a]iical margin somewhat elevated, entire, lateral 

 tubercles small, acute, base Ijiemarginate, dorsal channel obscure, more evident
