632 William T. M. Forbes 



Larva feeding on soft scales ( Pulvinaria) on Negundo and other trees, spinning 

 a light silken tube not unlike that of Feniseca. 



1. L. coccidivora Comstock. Light gray, heavily shaded with white on costa 

 and outer margin; antemedial line white, narrow, erect, and a little excurved 

 with a fine gray line before and a heavy shade behind it; postmedial line a little 

 waved, fine toward costa, heavily denned with blackish, becoming broader and 

 defined with broader shades of light fuscous toward inner margin. Discal dots 

 often fused, black; terminal dots black. 15-18 mm. 



General southward. New York: Albany. 



2. L. myersella Dyar. Similar to L. coccidivora, but without gray suffusion on 

 the inner half of the fore wing, the white reaching the inner margin. Lines 

 clean-cut and heavily gray-edged, the antemedial more waved than in L. coccidivora. 



September. 



Southern Pines, North Carolina. 



L. fiskella Dyar, from Pennsylvania and North Carolina, is unknown to me. 



98. CANARSIA Hulst 



Tongue strong; palpi with second joint reaching vertex and third slender; 

 maxillary palpi normal; front tufted; male antennae compressed, with sinus 

 and strong scale tuft at base of shaft. Fore wing (fig. 385) normal; Cu x from 

 angle of cell, M 2 and M 3 stalked; hind wings with Cu 2 a little before angle of 

 cell; discocellular as in Laetilia; Sc anastomosing with R. 



1. C. ulmiarrosorella Clemens. Fuscous gray, more or less dusted with white, 

 especially on the disc and outer margin. Lines double, darker gray, filled with 

 whitish; antemedial lines well out, wavy, postmedial line somewhat wavy and 

 irregular; the outer line of the antemedial often blackish, clean-cut and contrasting; 

 a whitish patch or shade beyond it on inner margin. Fine separate terminal dots; 

 discal bar high and narrow. 13-16 mm. (pneumatella Hulst, ulmella Ragonot, 

 fuscatella Hulst). 



End of June to August. Larva green with paler dorsal and stigmatal lines; 

 several segments with brown subdorsal dots; head pale brown with darker stains; 

 found on elm and, rarely, on hickory in a silk nest between leaves, in August. 



Canada to Texas. New York: Peru, North Creek, Otto, Ithaca, New Windsor. 



2. C. gracilella Hulst. Similar to C. ulmiarrosorella; paler, the markings 

 slightly more obscure. 



The types from northern New Jersey, appear to be merely somewhat pale and 

 rubbed specimens of C. ulmiarrosorella. 



99. PSOROSINA Dyar 



Fore wing with M 2 and M 3 separate; hind wing with Cu 2 at angle of cell, 

 M 2 and CUj stalked. Male antennae bent, with a tuft in the bend as in the last 

 genus; tongue moderate; palpi upturned to vertex; maxillary palpi filiform. 



1. P. hammondi Riley. Wings very broad, brown -black with some white scales, 

 the two usual lines nearly erect, fairly even and of white powdering, the post- 

 medial fading out at the costa, where there is a powdery white patch before it. 

 12 mm. (Canarsia auct.) 



Larva dull green or brown, with black tubercles; head pale with greenish face, 

 cervical shield black; feeding on pear, and also bred by Miss Murtfeldt from an 

 acorn. 



2. P. angulella Dyar is unknown to me. It is described as practically like 

 P. hammondi, but with an angulate antemedial line. 



Iowa.
