Rhynchagrotis cupidissi??ta, Grt. 



There is a long series collected by iMr. Buchholz in Yavapai County, 



Arizona, that shows a fine series of variations. As compared with the 

 preceding, this is a slightly larger species, tending to luteous or creamy, 

 a red tinge being exceptional, and usually accompanied by a dark s. t. 

 shade preceding the s. t. line, while the terminal space becomes paler. 

 There is rarely a distinctly darker costal blotch preceding s. t. line, 

 although the s. t. shade is always best marked on the costa. The second- 

 aries are almost blackish in both sexes, and the species is, on the whole, 

 very characteristic. 



The range of distribution is wide, specimens from Chicago matching 

 others from Arizona so closely that no differences are notable, and 

 California examples matching others from New Mexico. The Chicago 

 examples were taken by Mr. Healy in June and August, and while I 

 questioned the accuracy of the records when the specimens were first 

 received, there seems to be no doubt that the specimens were actually 

 taken there. 



Rhynchagrotis trigo?ia, Sm. 



This species differs at once from all the preceding in the shorter, 

 broader, more triangular wings. The primaries are usually of some shade 

 of pale luteous, tending to receive a reddish admixture in one direction 

 and a smoky admixture in another. As a rule, while all the maculation is 

 present in the specimens, it is scarcely relieved and does not disturb the 

 apparent uniformity of the wing. Exceptionally the ordinary spots will 

 become black, contrasting, and the lines, or some of them, may be blackish. 



I have a long series of examples from Colorado Springs in June and 

 July, a very long series taken by Mr. Buchholz in Yavapai Co., Arizona, 

 in July, and a small series from Fort Wingate, New Mexico, in July. 

 Altogether over loo examples, and enough to get a fairly good idea of 

 what the species looks like. 



Rhy?ichagrotis sa7nbo, n. sp. 



Has the trigonate primaries of trigona, but is smaller and the wings 

 are a little longer, not quite so stubby. Maculation also as in trigona, 

 but much better defined, the ordinary spots being usually black or 

 contrastingly darker, while the s. t. line is pale, preceded by a distinct 

 blackish or dusky shading. While there are some almost uniform examples, 

 the tendency is all in the opposite direction, the basal area becoming
