NO. 1208. NEW SPECIES OF TINEID MOTHS— BUSCK. 247 



externalh'. Cilia light golden yellow. Hindwings dsirk silvery gray, 

 cilia a shade lighter. Abdomen above, dark gray; underside silvery 

 and golden yellow. Legs silvery with broad black annulations. 



Alar expanse, 6.4 nun. 



Described from a single specimen, bred from Yerheslna virglnica, 

 collected at Palm Beach, Florida, bv Dr. Dvar. 



Type.—^o. 4957, U.S.N.M. 



The larva makes a roomy tent-shaped mine on the under side with 

 the lower epidermis much wrinkled longitudinally, and pupates in an 

 elongate white cocoon suspended at both ends like a hammock hiside 

 the mine. Larva belongs to the cylindrical group. 



I made no further notes on the larva, and even omitted to write Dr. 

 Dyar for more material to breed from, because I was convinced that 

 it was the mine and larva of Lithocolletk elephantopodella^ Yx^y and 

 Boll, which I have bred commonly from exactly similar mines on Ver- 

 besina at Washington, D. C. The moth, however, while belonging 

 in the same group with elephanUqjodeUa and arnhrosieUa^ is decidedlj^ 

 different, notably in the more angulated -and darker margined first 

 fascia and the complete, angulated second fascia instead of the costal 

 and dorsal streak of elepliaHtopodella.

 CORISCIUM RANDIELLA, new species. 



Antenna? longer than forewing, grey, each joint tipped with black. 

 Lal^ial palpi long, curved, second joint strongly tufted beneath, espe-

 line with the tops of the three undulations touching the fold and the 

 three bases of these undulations on the dorsal edge. The ]>lack mar- 

 gin of the last undulation and that of the last costal streak unite in a 

 small longitudinal spot. Cilia white with a short black dash on the
