distinct excavation below the apex. In wing form, dark colour and 

 similarity of sexes the relationship is closest to B. toreuta, Grt. 



Hypenula caminalis, n. sp. 



Ground colour smoky-blackish, with all maculation fragmentary and 

 obscure. Head, thorax and abdomen concolorous. Primaries with the 

 median lines denticulate, black, scarcely or not at all relieved from the 

 ground colour. T. a. line irregular, but on the whole nearly upright. T. 

 p. line rather evenly bisinuate. S. t. line very narrow, pale, irregularly 

 dentate. A very narrow pale terminal line and a series of preceding 

 black spots. The reniform is a narrow, upright, yellowish mark, scarcely 

 relieved. Secondaries with a dusky extra-median shade and a paler sub- 

 marginal line. Beneath, paler than above, powdery, more yellowish 

 toward base, a common extra-median shade line and an s. t. line which is 

 pale, broken on the primaries and continuous on the secondaries. 



Expands: 1.12-1.25 inches = 28-31 mm. 



Habitat : Cochise County, Arizona, June and July. 



Two males and seven females ; all in rather poor condition, from 

 Mr. George Franck. The species is obviously allied to acuminalis, but 

 is decidedly blackish instead of brown, and it lacks the white scales 

 characteristic of the Texan form. It seems also, on the whole, a little 

 smaller. The specimens had been papered and are all defective as to 

 legs. 



Renia rigida, n. sp. • 



Ground colour dull reddish-gray with a smoky shading which forms 

 the basis of the maculation. Head and thorax concolorous. From 

 the base to the median shade the primaries are of the reddish-ground and 

 contrast a little against the rest of the wing. The t. a. line is obscurely 

 indicated in the male, as is also the orbicular spot. The median shade is 

 broad, outwardly diffuse, makes the most conspicuous part of the macula- 

 tion and extends rigidly oblique from the basal I of the costa to the same 

 point on the inner margin. T. p. line single, crenulate, somewhat diffuse 

 inwardly and merging into the dark median area, squarely exserted over 

 the cell, then very oblique inwardly to the inner margin. The reniform is 

 upright, narrow, dusky with a vague paler margin. S. t. line is a more or 

 less obvious black shading before a fragmentary pale line which is a little 

 irregular, but on the whole parallel to the outer margin in course. There 

 is a series of black terminal dots on the interspaces, where the margin is a 

 little notched. Secondaries a little more blackish in tint, without obvious
