LEPIDOPTERA OF NEW YORK AND NEIGHBORING STATES 535 



female pale gray shaded with olivaceous aiid russet; the lines strongly dentate, 

 close together, black when distinct; discal dots strong and black, or lost in 

 blackish shade; hind wing gray in both sexes. 30 mm., the female usually larger. 

 (colonella Linnaeus.) 



Larva in nests of bumblebees and wasps, but not with honey bees; more rarely 

 in dried stores, cotton, books, borings of wood-borers, etc. 



Nova Scotia; Massachusetts; probably generally distributed; introduced from 

 Europe. 



Corcyra cephalonica Stainton (Tineopsis theobromte I3yar) is a common European 

 dried-food pest, to be expected in our territory. 



13. ACHROIA Hiibner 



Easily distinguished by the want of the frontal tuft. Antennae long, with a 

 scale- tooth on scape; palpi minute in male, shorter than eye in female; legs 

 slender. Fore wing of male oval; broadest toward base; 11 veins, one radial lost, 

 all the others free; R t arising opposite Cu 2 , Ciij as near Cu a as M,, M, well sepa- 

 rated. Female with fore wing more evenly elliptical, with M, and M 3 stalked; hind 

 wing with M 2+3 stalked with CUj. 



1. A. grisella Fabricius (The lesser bee moth). Pale gray-brown; the head light 

 yellow, contrasting; immaculate. Hind wings pale, with gray fringe. 17, 

 $ 21 mm. 



Caterpillar with the habits of G. mellonella and associated with it. It will also 

 eat dried apples, raisins, crude sugar, and apparently also dried insects. 



World-wide in distribution. 



Subfamily MACROTHECIN-ffi 



Near the Gallerinse, but slender species with close-scaled bodies. Palpi in male 

 very short, with a heavy tuft oh second segment above and below; third segment 

 very short, naked, and turned inward; palpi in female very long and beak-like; 

 maxillary palpi and tongue absent. Fore wing (fig. 315) narrow and thin, with 

 arched costa and rounded apex and outer margin. Macrotheca has R a shortly 

 stalked with R 3 _ji, I^ and R, the farthest; M x widely separated; M 2 and M 3 stalked; 

 cell about two-thirds length of wing; 1st A not chitinized, but with a wide space 

 in its position; 3d A anastomosing with 2d A but with a strong free tip, reaching 

 margin. Hind wing with cell extremely large, two-thirds length of wing; Sc 

 and R strongly anastomosing; the base of R reduced to a short spur; mdcv, 

 sharply right angled in middle, with a single rudiment of the base of M running 

 to its angle; M 2 lost; M 3 and CUj nearly connate; fringe on Cu obsolete; anal 

 region reduced, especially toward the base, and the veins very weak. 



The only known larva of the group is predacious on scale insects. 



14. MACROTHECA Ragonot 



1. M. unipuncta Dyar. Powdery gray; antemedial line far out, sometimes obso- 

 lete, black and dentate when distinct; postmedial obscure, irregularly sinuous, 

 followed by an imperfect second line. Discal dot a large black irregular spot. 

 Hind wing fuscous in male; female not seen. 



July. 



Western Pennsylvania. Apparently a form of this species occurs in Arkansas, 

 but its discal dot is small. It is not known from the intervening territory.
