136 AMERICAN HYMENOPTERA. 



contrasting spot. Orbicular large, irregular, outlined by black scales. Reiiiform 

 large, upright, a little constricted, outwardly margined with yellow scales and a 

 line of yellow scales centrally. Secondaries blackish. Beneath: dark smoky, 

 with a purplish wash, paler on secondaries on which is also a discal spot. 

 Expands 1.65 inches = 41 mm. 



Hab. — Corvallis, Oregon, March 11th (Cordley) ; Wellington,

Two good females, associated with carbonaria, but abundantly 

 distinct by the characters just pointed out. Carbonaria is locally 

 rather common, and I have had a great many examples under ex- 

 amination, so that I am familiar with its range ; but I never had 

 specimens like these taken with that species. 



Aleptina luteomedia n. sp. 



G-eneral ground color ashen-gray, ornamented and washed with luteous and 

 deep brown or black. Head usually, and often the collar also, luteous, with a 

 reddish tinge. Thoracic disc leaden-gray or darker, this shade sometimes involv- 

 ing the collar and in one example the head as well. Primaries ashen-gray, with 

 a luteous shading, which starts from costa at base, curves through the middle of 

 the wing without quite reaching the inner margin and terminates on the outer 

 margin below the apex. Inferiorly this shading is quite well limited ; but supe- 

 riorly it merges gradually into the gray which extends to costa. The usual me- 

 dian lines are much obscured and barely traceable. At base a deep brown shade 

 limited by a black line, extends obliquely outward to the inner margin, limiting 

 the luteous shade inferiorly, and a brownish or blackish powdering extends along 

 the inner margin to the point where it meets a curved blackish-brown shade 

 which forms an inner shading to a white line which extends from the middle of 

 the outer margin, with an incurve to the inner margin well within the anal an- 

 gle. Thi.s line is a little irregular and has a distinct tooth on vein 1. From the 

 apex a narrow blackish shade band extends obliquely inward to the lower angle 

 of the cell, forming here an inner margin to the luteous shading. On the costa 

 there is a dusky shade before and after the orbicular. The orbicular is small, 

 round, concolorous, clearly defined by a narrow black ring and with a black cen- 

 tral dot. The reniform is vaguely indicated at the end of the cell. The clavi- 

 form has in one example, an outline of rusty brown scales. There is a series of 

 leaden-gray or black terminal dots or spots, beyond which the fringes are cut 

 with the same color. Secondaries white, with a series of black terminal spots, a 

 variably evident broken extra-median shade line, and a small black discal spot. 

 Beneath : primaries powdery, smoky along the costal region, very pale yellowish 

 toward the margins, orbicular faintly reproduced, reniform marked .by blackish 

 scales and more evident than above. Secondaries white, with a distinct lunate 

 black discal mark, a series of black terminal lunules, and a more or less evident 

 extra-median line marked on the veins only. 



Expands .85-1.10 inches = 21-27 mm.
