added much to the labors of the journey does not detract from Mr. 

 Hutson's merit. No one sends better specimens than he does ! 



This species also has the cylindrical frontal process and will be 

 associated with catalina, I believe. 

 Thalpochares catalina, new species. 



Head, thorax and abdomen white, slightly lustrous. Primaries white, with a 

 slight creamy tinge ; immaculate to the middle, and nowhere with contrasting macu- 

 lation. Beyond the middle of costa a vaguely luteous band bends outwardly through 

 the cell, there forms an obtuse angle inward, becomes better marked and broader, 

 reaching the inner margin a little beyond the middle. This band varies in width and 

 in distinctness. At the outer border is a broad margin of faint bluish gray, through 

 which the white, slightly sinuous s. t. line is traceable. A series of black terminal 

 dots is obvious in one specimen. Fringes white. Beneath ; primaries blackish, 

 fringes white ; secondaries white. 



Expands. — .80 inch = 20 mm. 



Habitat. — Yuma Co., Ariz., April 19, Hutson ; Babaquivera 

 Mts., Pima Co., Ariz., July 16-23, Dr. Barnes; Tuscon, Ariz., May 

 13-14 and Catalina Springs, Ariz., July 5, Mr E. A. Schwarz. 



Three males and three females, half of them in rather ragged con- 

 dition, yet all characteristic. Seems to be rather widely distributed, 

 yet obviously not over-common. 



It is probable that this species will have to be removed from Thal- 

 pochares eventually, because like so many of our desert forms, this has 

 a frontal protuberance, cylindrical and truncate, covered by the vesti- 

 ture in good examples but readily exposed. I do not propose a new 

 generic term here, because the species of this and allied genera are 

 not well represented in collections and the limits of the genera already 

 named are by no means accurately defined. 



Bomolocha lutalba, new species. 



Ground color a dirty luteous gray ; head and thorax immaculate, abdomen paler, 

 with narrow whitish segmental rings. Primaries more or less shaded with smoky, with 

 a conspicuous rigid narrow yellowish s. t. line, more or less defined by a dusky preced- 

 ing shade, more distinct in the male than in the female. T. a. line single, smoky, 

 rather broad, somewhat diffuse, with small outcurves between the veins and as a 

 whole a little outcurved. T. p. line narrow, smoky, not well defined, irregular yet 

 scarcely crenulate, well curved over the cell and as deeply drawn in below. There is 

 a broken, scarcely lunate terminal line. Reniform an obscurely defined dusky blotch 

 of moderate size. Secondaries whitish ; there is an outer, rigid yellowish line abruptly 

 bent near anal angle, preceded by a dark shading, which seems like a continuation 

 of the s. t. line of primaries ; toward the base there is a less distinct continuation of 

 the t. a. line of primaries. Beneath, both wings with a slight reddish tinge, powdery, 

 with smoky median and extra-median lines and a dusky discal spot.
