368 THE CANADIAN ENTOMOLOGIST, 



in from apex, to anal angle, these markings are enclosed with a deep rosy 

 pink, cut with short white strigse. From hase below costa to this curved 

 line, golden-orange as above, without other markings. Secondaries deep 

 rose-pink. Some irregular costal blotches, and the veins, are a rich 

 creamy-brown, the whole surface irregularly strigate with black and white, 

 the latter forming a patch at costa near apex, and a large irregular discal 

 dot. Fringes as above, but less pink, and more heavily cut with brown 

 and white. Body and abdomen beneath whitish, decked with creamy- 

 brown and deep rose-pink. Legs whitish, barred terminally with 

 creamy-brown, and washed basally with rose-pink. 



Types : Two males taken at Palmerlee, Cochise Co., Arizona, in 

 July, by Messis. Doll and Schaffer. One of these is in the Brooklyn Inst. 

 Museum, the other was kindly donated to the author, and is in his 

 collection. 



Morrisata, Hulst, is a Petrophora, and a synonym of volucer, Hulst 

 (vide Grossbeck, Trans. Am. Ent. Soc). My paper does not definitely 

 dispose of all the species listed as Coetwcalpe, and in that respect is 

 unsatisfactory to me, but it has required two years of effort to -advance 

 thus far, and I feel that some portion of them would better occupy a fixed 

 position, leaving the future to determine for the rest. 



The American Drapetisca. — Drapetisca was erected for the species 

 socialis, Sund., which has remained its sole known representative. A 

 form found in the United States has always been regarded heretofore as 

 belonging to this European species ; but a careful comparison with speci- 

 mens from Europe shows it to be different. It may be designated as 

 Drapetisca alteranda. 



The two species may be separated clearly through structural 

 differences, both in the epigyna of the females and in the palpi of the 

 males. Among these differences may be mentioned that the distal 

 portion of the epigynal plate in alteranda is subcordiform, whereas in 

 socialis it is quadrangular, with the angles not much rounded ; and that 

 in the palpus of the first form the apophysis of the bulb is larger and 

 decidedly more acute apically than in the European species.
