34 AMERICAN LEPIDOPTERA. 



densed into spots and blotches, an elongated patch at basal part of 

 costa, an irregular spot at one-third, a larger one at three-fifths and 

 another smaller one at about three-fourths of costa, from the latter 

 begins a strongly curved or subangulated line in apical part of wing 

 which ends in a spot on the dorsal margin beneath the end of cell ; 

 from the second costal spot starts an irregular angulated line or 

 fascia, which ends in a dorsal spot just before the middle, this line 

 reaches to the very distinct first discal spot above the fold, and also 

 another less distinct spot beneath the fold. Two well marked spots at 

 end of cell ; a row of dark spots along periapical margin which send 

 short streaks into the basal half of the cilia ; there is some condensa- 

 tion of the dusting along the fold, and a more or less distinct blotch 

 on the dorsal margin near the base. Cilia yellowish-gray, with a pale 

 line before the middle and another less distinct before the free margin. 

 Hindwings nearly 1, obtusely pointed, yellowish-gray, dusted with fus- 

 cous and having considerable lustre ; cilia pale grayish-yellow, with 

 pale basal line. Abdomen grayish-fuscous above, grayish-ochreous 

 beneath, especially towards the end, anal bush grayish-ochreous. 

 Legs pale grayish-yellow, dusted and spotted with fuscous, ends of 

 tibiae, an oblique band on posterior tibiae externally and ends of tarsal 

 joints paler. Expansion 14.0-16.0 mm.,. 0.52-0.64 inch. 



Hab. — Atlantic and probably Middle States. 



The two specimens representing the types in the Clemens' 

 collection at the Academy of Nat. History, Philadelphia, and 

 labeled as such by Mr. Busck are not identical, the specimen 

 bearing label 201 is the type and corresponds with the de- 

 scription. The other specimen marked 202 and marked 

 light variety, corresponds rather with modestella Clem. 



I have bred this species in considerable number from the 

 fruit racems of sumach — Rhus typhosa — collected end of July. 

 The imagines appearing from middle to end of the following 

 June. It is my opinion that the larva? is predaceous on other 

 larva?. 



There are several variations from the typical form which 

 require special mention. 



Var. minorella. (Plate II, fig. Vie.) 



A somewhat smaller form, of which six specimens are 

 before me, four in the Nat. Mus. Coll. and two in the collec- 

 tion of Mr. W. D. Kearfott. They all bear the label " Lewis- 

 burg, Pa.," bred from chestnut burrs. Four of the speci- 

 mens have the dark dusting of the forewings much more dif-
