XXIV. New Phalaenoid Moths 



BY LEO]Sr F. HARVEY, A. M., M. D. 



[Read before this Society, January 2, 1874.] 



The collection of this Society contains specimens of the follow- 

 ing Moths, which, among others, have been handed to me for study 

 and identification by Mr. Grote. One genus and three species, 

 described in the present paper, belong to the Bombyces (Phalaenae 

 Hiibn., Bomhycidae Auct.), and three species to the (jJ-eometrae 

 {Geometridae Auct.), 



BOMBYCES. 



Heteropaclia, n. g. 



This generic term is proposed for a form allied to Gasteropaclia and our 

 American genera Tolype and Artace, while in its colors it recalls the dusky 

 olivaceous species of Heterocampa. The eyes are hairy ; the ocelli probably 

 wanting ; the antennae {$) short, with double, lengthy, converging pectinations 

 which shorten over apical two-thirds ; the body parts are shaggily haired. The 

 fore wings are narrow, widening externally, thinly scaled, entire ; hind wings 

 ovate, with costal shoulder ; primaries 10-veined, cell open ; 2 from the me- 

 dian vein near the base, 3 half way between 2 and 4 and thrown off at about 

 the center of the wing, 5 the termination of the nervure ; subcostal nervure a 

 little bent ; 6 and 7 on to external margin, a short furcation ; 8 a little below 

 apex, 9 to costa ; hind wings 9-veined, cell opened ; 9 a short bent veiulet on 

 the costal shoulder, 6, 7 and 8 arising near together at basal third, 6 thrown 

 off below — a long vein to apex, 7 to costal margin within the apex, 8 a short 

 vein to costa at about the middle of the wing. The abdomen is as long as the 

 hind wings and the thoracic disc is destitute of the metallic scales of Tolype. 



Heteropaclia Rileyana, Earvey, Plate 11, fig. 1. 



$ . — Dark grayish fuscous ; primaries with two irregular, light gray, con- 

 tinuous bands, the first at base, short, the second, fainter, at apical third, 

 followed by a series of subterminal dots on the veins ; external margin with 

 indistinct gray dots ; veins marked ; the denuded integument shows an irides-
