92 LORD WALSINGHAM ON NEW TINEID.E. [Feb. 17, 



to consist of two elongate triangular spots, one on the costal and one 

 on the dorsal margin, joined on the middle of the wing by a narrow 

 streak running inwards and upwards, and connecting the apex of 

 the dorsal spot with that of the costal; halfway between the 

 fascia and the apex is a small elongate white costal spot ; the cilia 

 are also white, except at the angle, where they are brown. Hind 

 wings greyish cinereous. 

 Expanse 22 millims. 



1 cJ , reared from a larva found boring in the stems of a species 

 of Saxifrage, on rocks near Canyon City, on John Day's River, 

 Oregon, March 30, 1872 ; bred May 22nd. The larva, which 

 I did not describe at the time, has much the habit of that of 

 Lampronia ruliella (Bjerk.), boring in the inside of the stems of its 

 food-plant, the empty pupa-case protruding from the injured 

 shoot. 



Lampronia TRiPUNCTELLA. (Plate XII. fig. 10.) 



Cainte hirsuto flavo ; antennis fusco et alho annulatis ; alls anticis 

 subpurpurescenti-brunneis, fascia basali, maculis (duabus cos- 

 talibus, una dorsali) triangular ibus cum ciliis subflavescenti- 

 albidis, posticis subpurpurascentibus. 



Head rough above, yellow. Antennae faintly annulated with 

 white and fuscous. Fore wings rather purplish brown, with a 

 faintly yellowish white fascia on the basal fourth, somewhat wider 

 towards the dorsal margin, and with two costal and one dorsal spot 

 of the same colour, all somewhat triangular, of which the dorsal 

 (which is beyond the middle) is the largest, and the outer costal is the 

 smallest ; the cilia also faintly yellowish white, except at the anal 

 angle. Hind wings pale purplish, with slightly paler cilia. 



Expanse 14 miUims. 



One specimen, purchased in a miscellaneous collection from North 

 America. No exact locality given. 



The ornamentation of this species reminds one much of Herrich- 

 Schaffer's figure 275 of Tinea vinculella, H. S., which, however, is 

 a much smaller insect and has not white cilia.
