Ahir crpa/i-se. — 15 to l(> iiii)\. 



Hahitaf. — Colorado, Florida. South Oirolina. 



Type.—^o. 6374, U.S.N.M. 



This .species is very close to the foregoing- three species, especially 

 to ai'izonelld Rusck, ))ut at once distinguished from this l^y its pure 

 white face and hhick head, b}- its light palpi and white l)arred legs, as 

 well as by the slight diti'erence in wing ornamentation. 



The name of the species is a misnomer because while the typ<\s of 

 the species came from Colorado I have subsequently identified it from 

 Florida and South Carolina.

Types of both species with Chambers' labels on the pins are found 

 in the Museum of Comparative Zoology in Cambridge, and prove, 

 as the descriptions would indicate, that it is only one species twice 

 described. 



A large bred series, showing considerable variation in the white 

 markings, is found in U. S. National Museum, determined by Lord 

 Walsingham as ejjlgseeUa. 



Food plant — Vacciniani staimneiim. — The following are the notes 

 on this series in the U. S. Department of Agriculture, given under 

 No. 2788: 



An apparently very numerous larva of a skeletonizer on Vaccininm stamineum was 

 found in Virjifinia (presumably by Mr. Then. Pergande and near Washington City) 

 on July 16. The larva fastens together two or more leaves and feeds between them 

 on the epidennis, forming from its frass a tube, which is open at both ends. The 

 larva is about 8 mm. long, pale dirty yellowish or greenish yellow, with six darker 

 yellow stripes, head and cer\ical shield dark yellow; moths issued from July 26 to 

 August 17. 



Chambers' type was bred from the nearly related Ejyigsea repens 

 In U. S. National Museum is another series of apparently this samel 

 species bred from sweet fern, Comptonia aspleni folia, and also identi- 

 fied by Lord Walsingham as epigaedla Chambers. This would be anj 

 unusually diverse food plant for a Gelechiid, and I was suspicious that 

 the latter series would prove another species, as it eventually may. 

 But the rather ample material can not be separated at present except 

 by the labels, and the notes on the larvje are so similar that for the j 

 time being at least I must assume all to be one species. 11 



Should it ultimately prove to be two species by more accurate ol)ser- 

 vations on the larvffi, the species on Comptonia might property be
