Described from eight specimens bred from larvae boring the 

 tender terminal twigs of Buckeye and of Maple in Missouri. 



The indentation in the posterior border at the apex of vein 4 is 

 often difficult to detect on the upper surface because of the heavy 

 fringe, but on the lower surface it is always distinct. Vein 4 

 comes very close to vein 5 at the apex, 



MELISSOPUS,* Nov. Gen. 



Primaries twice as long as wide, the costa gently and evenly arched, 

 posterior margin scarcely indented below the apex; no costal fold : vena- 

 tion as in Carpocapsa pomondla : the wing banded with coppery. Second- 

 aries slightly indented below the apex : venation differing from that of 

 C. pomonella in vein 2 springing from the basal third of the discal cell : 

 behind and parallel to the base of the median vein and vein 2 a pencil of 

 hairs concealed in a much deeper pocket than that of Carpocapsa, the 

 pocket forming a conspicuous process on the lower surface of the wing : 

 a dense cluster of peculiar hair-like scales, with broadly spatulate tips, 

 along the inner border. Posterior tibice dilated and compressed, clothed 

 with long scales forming a large brush resembling a miniature and flat- 

 tened " feather duster": the posterior tarsi also with long scales, particu- 

 larly on the basal joint which is also dilated. 



This genus resembles Ecdytolopha Zeller (Beitriige z. Kennt. 

 nordam. Nachtfalter iii. p. 60 [266]) in some respects, but may 

 easily be distinguished by the absence of the stout scutellar tuft 

 which belongs to that genus ; by the singular mat of spatulate 

 hairs on the anal margin of secondaries, and by the peculiarly 

 broad and brushy hind tibiae and tarsi. 



Melissopus LATiFERREANA (Wlsm.)— c?- Expanse 17-18 mm. Gene- 

 ral color reddish-brown, with metallic reflections on the primaries. Head 

 grayish- brown ; palpi white, exteriorly towards tip fuscous. Thorax 

 above speckled with gray and brown : primaries reddish-brown, speck- 

 led with gray, especially at base ; a rather narrow coppery median 

 fascia, almost straight, constricted at middle and widest on the inner 

 margin; a second more arcuated fascia of the same color, broadest 

 along the ocellated spot and broken just above it, and a third, narrower 

 and more broken, fascia extending from outer fifth of costa and curving 

 near posterior margin to anal angle; ocellated spot merely indicated by 

 a series of interrupted, black longitudinal lines and a few black specks 

 along inside of the posterior metallic fascia; a few metallic costal streaks 

 and an apical spot of same color; fringes gray, preceded by a dark red ter- 

 minal line: secondaries fuscous, paler toward the base, fringes whitish;
