68 JOHN B. SMITH. 



Oiicociieinis extranea u. sp. (PI. i, secoud row, fi^. 4)— Gray, with a 

 fuscous admixture. Head brown. Collar with a black line at base, and a more 

 brownish one near tip. Primaries powdered with fuscons, this powdering be- 

 coming more dense outwardly, until in the terminal region the wing is dark 

 fuscous; this dark space crossed by black interspaceal marks. The median lines 

 are very vaguely traceable, but scarcely describable. A dark, slender, terminal 

 line. Fringes pale, cut with fuscous. A black dash at base in the submedian 

 interspace, at the end of which is the concolorous claviform, outlined in fuscous 

 and with a fuscous centre. The ordinary spots are fused into a slender, elongate 

 macula, somewhat enlarged outwardly and black filled. Secondaries fuscous, 

 much paler basal ly and with whitish fringes. There is an evident discal dot. 

 and the darker outer region is fairly defined. Beneath, whitish powdery, with 

 a rather broad dusky outer margin and a distinct discal dot on all wings. Ex- 

 pands 31 mm. ; 1.25 inches. 



Hub. — Colorado, Bruce. 



A single good male specimen is before me. The species belongs 

 to the atricollaris group, and resembles somewhat the preceding at 

 first sight, differing markedly, however, on a more careful examina- 

 tion. The dusky secondaries will separate the present form at a 

 glance. It has a casual resemblance to Carneades hoUemani- 



CEROPODA n. gen. 



Eyes naked, hemispherical, large. Palpi rather small, scarcely 

 exceeding the front. Tongue long and strong. Vestiture of front 

 rather even, forming an obtusely truncated tuft between the antennae. 

 The latter in the female arc simple, in the male have the joints mo- 

 niliform or somewhat bead-like, laterally furnished with tufts of 

 rather stiff hair. Front smooth. Thorax moderate, convex, vesti- 

 ture mixed hair and scales, forming a very feeble anterior crest and 

 a very little better marked posterior tuft. Legs moderate, clothed 

 with long and rather thin vestiture. Tibiie not spinulated, the an- 

 terior furnished at tip with an outwardly curved, divergent spine or 

 claw ; the first tarsal joint has one such claw at middle, and another 

 at tip; the second tarsal joint has one such at tip, and the third and 

 fourth joints have each a smaller, straight divergent spine at tip. 

 Wings rather large, primaries widening rather regularly from base, 

 apex pointed, outer margin quite oblique. Secondaries proportionate; 

 vein 5 weaker than the others and from the cross- vein. Abdomen 

 untufted, in the 9 obtusely terminated. 



The genus resembles Oncocnemis in some respects, and particu- 

 larly the whitish forms like cibalis and gracUlima. It differs from 

 all the naked eyed genera known to me in the peculiar armature of 

 the fore legs, in which it resembles Trichoclea in some respects.
