A slight difference in the shape of the valves of the male genitalia ; 

 less triangularly scaled palpi ; coupled with more elongate scales on 

 the primaries; lead the authors to consider this species distinct from 

 plagiata Wlk. (^=pinicola Dyar). 



Olene bonnivvelli sp. nov. 



Palpi triangularly scaled, brownish marked with black. Head and collar 

 brownish, intermixed with black. Thorax black mixed with brownish. Pri- 

 maries ; ground color pale grey, tinged with brownish, and heavily powdered 

 with black ; basal line black, outwardly oblique from costa to inner margin ; 

 a black basal dash below the cell extending nearly to the t. a. line ; t. a. line 

 broad, black, somewhat waved, but without prominent angles, slightly oblique, 

 outwardly, from costa to inner margin ; reniform large, outlined by black, with 

 a brownish center, the whole more or less surrounded by a patch of pale grey; 

 t. p. line strongly excurved from costa around cell, thence strongly incurved 

 in submedian fold, nearly forming the letter S on the left side, reversed on 

 the right, only slightly waved, without inward angle on vein 1 ; a large black 

 spot in the submedian fold bordered distally by whitish ; s. t. line a diffuse shade, 

 more or less obsolescent, outwardly oblique from costa to below vein 7, thence 

 inwardly oblique, waved, irregular, in all specimens before the authors obso- 

 lescent below vein 3; a black terminal line interrupted by the veins; fringe 

 brownish-grey slightly checkered by paler grey. Secondaries: nearh' uniform 

 dark-brown, with a large but obsolescent discal spot ; fringe concolorous, slightly 

 checkered by paler brown. Beneath : dull brown, powdered with black, costal 

 areas of all wings and inner area of primaries paler; primaries with the cell 

 more or less filled with fuscous, t. p. line and reniform showing : secondaries 

 with a diffuse fuscous median shade, and discal spot with a bar of scales in 

 the cell. 



Expanse: 39-40 mm. 



The series before the authors shows very little variation. 



The present species is allied to grisefacta and plagiata (^=pini- 

 cola), the scales on the primaries similar to those of grisefacta but 

 the coloration darker, the palpi more triangularly scaled, and numer- 

 ous small differences in the various lines and spots; palpi, maculation 

 and color somewhat similar to plagiata but lacking the usual whitish 

 shade following the s. t. line, while the scales on the primaries are 

 much narrower and more elongate. 



While the genitalia of the various species of Olenc do not present 

 strikingly different characters, the valves of the present species appear 

 different from those of its allies, while lol>ate being considerably in-
