ASYCHNA. 



A. ? pulvella. N. sp. 



This species is placed in this genus provisionally. It is certainly not 

 a true Asychna. Indeed, almost the only character common to all the 

 species which Mr. Stainton places in this genus is their ornamentation, 

 and in this respect Laverna ? gleditschiceella is an Asychna, whilst this 

 species is far from it. This species (pulvella) differs widely enough from 

 all the others in ornamentation ; but structurally it approaches this genus 

 so nearly that rather than construct a new one for it, I place it here pro- 

 visionally. Taking for comparison Mr. Stainton's figures in Ins. Brit., v. 

 3, the wings of pulvella resemble those of A. ceratella more nearly than 

 any of the other species. They are, however, more narrow and elongate; 

 the dorsal margin of the fore wings is nearly straight, while the costal 

 curves down to it nearly as in A. modestella reversed ; that is. the costal 

 of modestella represents the dorsal of pulvella, and the dorsal of modestella 

 is a little more curved than the costal of pulvella. The neuration is 

 exactly as in ceratella, except that the cell is unclosed in the fore wings 

 and in the hind wings pulvella has one more branch of the median vein 

 (placed between the second and third of ceratella), and continued through 

 the cell. The palpi are more like those of A. terminella. The antennae 

 are slender, longer than the body, and shorter than the wings. Its 

 attitude in repose resembles that of Bedellia somnulcutella, to which it 

 bears some resemblance in coloration. 



Head, palpi, antennae, thorax and fore wings whitish, but so densely 

 dusted with ochreous brown as to obscure the ground color ; the antennae 

 are faintly annulate with whitish, with three large white annulations before 

 their tip, which is also white ; the second and third of these annulations 

 are intermediate between the first and the tip. The fore wings have a 

 brown streak along the fold and another further back on the disc, and a 

 small white spot at the end of the cell. The ciliae are grey, those of the 

 apex dusted with ochreous brown. Upper surface of the abdomen of the 

 general hue ; beneath it is paler and the anal tuft is silvery white. Legs 

 of the general hue, the tarsi annulate with white and the first pair brown- 

 ish on their anterior surfaces. Al. ex. 3/% inch. Kentucky in June.
