28 Grote and Robinson's Lepidopterohyicdl 



Eesembles Abbot's figure of 9 Oatocala amaxi'a Smith sp. in the 

 conformation of the t. p. line, but differs in detail. The sexes are simi- 

 lar in C. formula nobis. We have difficulty in believing that the 

 very different male C. canasia, is properly associated with the female 

 figured by Abbot. In this case the male would retain the specific 

 name proposed by Sir. J. E. Smith. 



Catacola scintillans, n. s. (Plate ?>, fig. 6, % .) 



Anterior wings of an even dark brown color, which extends from 

 their base to the subterminal line, obscuring the ordinary lines which 

 are obsolete and faintly indicated by darker costal marks. This dark 

 portion of the wing is overlaid with greenish bronzed metallic scales 

 arranged into transverse narrow stripe, which give the wing, in certain 

 lights, a brilliant reflection. At base, below the internal nervure, the 

 squammation is paler. From the s. t. line to exterDal margin the 

 squammation is grey shaded with pale brown scales following the course 

 of the s. t. line which is regularly dentate, sloping inwardly before costa ; 

 the pallor of this portion of the wing contrasts forcibly with the dark 

 hue of the rest. The nervules, terminally, are covered with mixed 

 pale and dark scales. A continued series of dark brown interspaceal dots; 

 a narrow dark terminal line, than which the fringes are a little paler. 



Secondaries, orange yellow; internal margin clothed with long, very 

 pale brown hairs. Median and terminal bands, brownish-black; the 

 former, slightly irregular and becoming very narrow just before inter- 

 nal margin, the latter, even, with but a single slight distention at a 

 little within its middle. Terminally there are a few narrowly arranged 

 orange yellow scales which, however, do not distend into the usual api- 

 cal mark ; fringes pale. 



Under surface much as in C. innubens Guenee; the secondaries are 

 largely covered with orange colored scales; median band distinct and 

 tapering to internal margin. 



Head and thoracic region above, covered with mixed pale and dark 

 brown scales. Abdomen pale testaceous brown, nearly concolorous with 

 the long hairs which clothe the internal margin of the secondaries. 

 Under surface of body very pale; anterior tarsi brown on their upper 

 surface, sub-annulate. 



Exp. % 2.00 iuches. Length of body 1.25 inch. 



Habitat. — Pennylvania. Coll. Ent. Sec. Phil. 



The peculiar ornamentation of the upper surface of the primaries is 

 very distinctive and curiously reminds us of certain species belonging 

 to the Sphingid genus Erinnyis.
