North American Coleophora. 441 



along the whole length of the fold, beyond the middle of 

 which are sometimes two or three black scales ; above 

 the fold, from beyond the middle of the cell to the dorsal 

 margin below the apex, is another short white streak, 

 containing two distinct black dots or spots ; the extreme 

 apex is black, with black spots at the base of the cilia, 

 on the costal and dorsal margins above and below it. 

 Cilia white, pale grey above the anal angle. Hind wings 

 and cilia pale grey. Third pair of legs tinged with 

 ochreous. Expanse, 10 mm. 



A single specimen in my collection, received some 

 years ago from Texas (Belfrage). 



CoUophora castipenndla , n. s. (PL XVII., figs. 16, 16«). 



Palpi somewhat thickly clothed, white, the apical 

 joint brown above. Antennae white, distinctly annulated 

 with brownish ochreous, having a very long and con- 

 spicuous white tuft on the basal joint. Fore wings 

 white, without any sprinkling of dark scales. Cilia pale 

 greyish ochreous. Hind wings grey, with pale greyish 

 ochreous cilia. Abdomen greyish. Legs white, the 

 tarsal joints touched with pale greyish fuscous. Expanse, 

 14 — 17 mm. 



The larval case is pistol-shaped, without projecting 

 flaps at the sides, pale brownish ; sometimes blackish 

 above and beneath, but not entirely black, as that of 

 Colcopliora anatrpennella, Hub., from which it differs in 

 being "somewhat thickened laterally about the middle, 

 where there is a curved transverse mark on its upper 

 side, giving it the appearance of being constructed in 

 two separate stages. There is a slight projection also 

 on the under side, in the position which might be 

 occupied by the trigger-guard of the pistol. The mouth 

 of the case is oblique, causing it to incline at about the 

 half of a right angle from the surface of the leaf on 

 which it rests. Length of case, 8 mm. 



Two specimens found feeding on a species of Salix in 

 Lake County, California, June '26, 1871 ; others taken 

 near Pit Eiver in the middle of July.
