respects it more nearly resembles the genus SimcBthis, where it may 

 iinally land. 



2. A triangular ochreous area extending from tip along one-third 

 of costa, thence to hind angle ; this is divided by a paler ochreous 

 wedge-shaped streak, widest at costa and pointed at hind angle. 



3. On the costa, enclosed by the pale ochreous streak is a white 

 spot, or triangular dash, base line along costa, lower apex pointing 

 towards hind angle. There are two additional minute white costal 

 spots, at equal distance apart, between this larger spot and base. 



4. In fresh specimens the inner half of primaries are very thickly 

 powdered with cream color scales. 



Choreutis dyarella, sp. nov. 



Dark brown, mixed with whitish scales. Fore wings shaded with bronzy red, 

 most distinct on apical half; a few metallic scales towards base. A straight white 

 shade from costa to inner margin at basal third, forming a distinct spot on costal edge. 

 A similar narrow line at outer third forming a dot on the costa, two at end of cell and 

 one on internal margin. A strongly curved line of metallic scale joins the costal and 

 marginal dots, is twice broken and touches outwardly the third transverse white band, 

 which reaches from costa before apex to anal angle and is nearly continuous, and is 

 broken only at upper third where the metallic scale band touches it. The submar- 

 ginal streak of metallic scales not reaching the apex. Fringe white, black at apex 

 and anal angle with a brown spot in the middle. 



Hind wings blackish, the usual submarginal dash yellowish-white, distinct. 

 Fringe black with basal yellowish-white line ; outer half white except at apex and 

 anal angle. 



Wings below smoky brown. Two obscure white dots on costa and a few scales 

 outwardly on fore wings. Hind wings with outer irregular white curved line with a 

 lunate white discal streak. Tarsi strongly banded with white. Femori blackish, 

 with a median whitish band. Expanse, 12 mm. 



Described from three specimens from Dunsmuir, Cal. (Wickham). 



National Museum type No. 6263, one co-type in my collection. 



I take pleasure in naming this species after Dr. Dyar. 



This is a slightly larger species than inflatella, but it belongs to 

 the same group, with acutely pointed fore wings. 



It can be distinguished from inflatella by : (i) Larger size, (2) 

 no metallic scales on hind wings, and (3) white submarginal band 

 on under side of hind wings, in inflatella this band is reduced to a 

 fine almost obsolete line.
