260 NATHAN BANKS. 



Mountains, Rio Riiidoso, 6,500 ft., July 30th ; Santa Fe, July, and 

 Magdalena, all New Mexico; a female from Vancouver Island, 

 British Columbia. 



Differs from M. iimovata in marks on vertex, and more black 

 cross-veins, in shape of the horn, and especially in the long and 

 swollen third antennal joint. Some of these specimens were form- 

 erly referred to 31. innovata, but with more material the}' appear 

 distinct, and I do not know that M. innovata occurs north of 

 Mexico. 



IVIeleoinsi pallida n. sp. — Head pale yellowish (green in life ?,),no marks 

 under eyes, palpi pale, unmarked; antennae very wide apait at base; tbe horn 

 short and broad, divided by a furrow in the middle, slightly concave in front ; 

 basal joint of antennae very long, swollen near tip, third not elongate nor swol- 

 len ; vertex and thoiax unmarked. Wings hyaline, venation green, many cross- 

 veins black in part, the gradate series brown, but the branches of anal are mostly 

 pale; stigma indistinct in both pairs. Expanse 37 mm. 



From Huachuca Mountains, Arizona, August 20, 1905, 8,000 ft.,

 both pairs. Forewings rather broad, costal region broad near base, three radial 

 sectors, and the first not connected to radius, the third connected to radius once ; 

 the last veinlet of the inner gradate series slightly before or at the preceding 

 veinlet; in the hind wings the fork of radial sector is even with the fork of the 

 median vein. The male appendages are similar to those of B. coloradcnuis. but 

 (seen from the side) are much narrower at tip. Expanse 15 mm.
