 Euto. Am. iv, 116, 18S8."Exi)iinfls 18 mm. Fore wings broad, arched near base; 

 gray, strongly washed with blackisli brown and reddish, tlie costal half of the 

 basal area white, the rest flesh colored. First line very oblique, reddish, edged 

 with blackish posteriorly, preceded by a straight line of raised blackish scales. 

 .Second line grayish, edged with black, slightly sinuous; discal spots distinct. 



My species, albocapitella, seems to differ materially from this de- 

 .scription, but Mr. Ragonot has seen my type, and pronounces it the 

 same as his palliolella. My original description was as follows : 



Expands 14 mm. Palpi, head and thorax snow-white ; abdomen white, slightly 

 stained with fuscous : fore wings white at base, with a faint reddish fuscous stain 

 along costa and inner margin ; basal line dark brown, rather indistinct; wings 

 beyond fuscous gray, except along ba.sal line on inner margin, which Is whitish : 

 outer* line gray, indistinct, rounded in middle outwardly, edged within with 

 dark brown; veins slightly darker than ground color; hind wings pellucid fus- 

 cous, darker outwardly. 



Canada. 



Mr. Ragonot gives no locality. 



2. A. carya>voreIla Rag., Diag. N. A. Phyc. p. 4, 1887. — Expands 23 mm. 

 Fore wings broad, strong, rounded on costa and hind margin, dark bluish gray, 

 nearly black ; lines dark gray, edged with black, the first straight to median 

 vein, then oblique to costa, preceded by a line of raised scales ; second line sinu- 

 ous, indented on the folds, rounded and dentate in the middle. Discal spots 

 distinct. Hind wings fuscous, head reddish. 



Missouri. 



I do not know this species.

 U. S. Geol. Surv. Terr, vi, 590, 1880; mlnimella Rag., Ento. Am. v, 113, 1889.— 

 Expauds 22 mm. Head and thorax very pale reddish. Basal field limited by the 

 curved anterior line, pale reddish ; a blackish shade before the line, resting on 

 internal margin, and followed by a red shade; median space fuscous. Discal 

 dots separate. Posterior Hue denticulate and exserted over median nervures, 

 indented below costa and on median fold, followed by a reddish shading. Hind 

 wings smoky, subpellucid ; beneath with two thick, black, basal dashes, one on 

 costa the other along median vein ; fore wings fuscous beneath, pale aloug costal 

 region at base. 



New York. 



Mr. Grote further says this species has been bred by Mr. Akhurst, 

 of Brooklyn, from larv?e boring into the leaf stems of the hickory 

 (Carya iip.). Mr. Akhurst has told me the work of the larva^ is 

 very observable in the spring, for every young sprout bored into 

 withers away and dies. Often trees have a dead appearance in view 

 of the ravages of this insect.
