Yersinia Saussure. 



I know of but a single and undescribed species in the United States, 

 of which I have specimens obtained by Morrison, in Colorado, on the 

 plains at the base of the Rocky Mountains, and by myself at Garland, 

 Costilla Co., Colorado, at a height of about 8,000 feet. Probably it is 

 this species which Bruner found in Western Nebraska and referred 

 (Publ. Nebr. Acad. Sci., 1893, 22) doubtfully to Y. mexicana. The 

 species, which may be called Y. solitaria, is slenderer and slightly 

 smaller than Y. mexicana, and is apterous in both sexes. 



LiTANEUTRiA Saussure. 

 The only species of this genus heretofore known as such was 

 described from Sonora, but we have more than one species in the West. 

 One is L. t?iinor {Stagniatoptera mifior Scudd.), figured by Glover (111. 

 N. A. Ent., Orth., pi. 13, fig. 12), and of which I have seen specimens 

 from Texas, New Mexico, Utah, Colorado, and Nebraska. It was 

 originally described from the ? only. A very small ? , apparently of 

 this species, from Bridger Basin, Wyoming, is in the Museum of Comp. 

 Zoology. Bruner has also sent me specimens from Arizona, California, 

 and Kansas, and it is probably the '■ Ameles sp." mentioned by him (N. 

 A. Fauna, VII., 266) as found in New Mexico, Arizona, California, 

 Southern Idaho, and Middle Nevada. The undescribed " Ameles 

 borealis " of Bruner (Publ. Nebr. Acad. Sci., 1893,22), from Northern 

 and North-western Nebraska, of which he has kindly shown me a pair of 

 9 's, is perhaps distinct from it, with smoother pronotum. Another species, 

 closely allied to this, differing indeed only, so far as I have seen, in the 

 far greater depth of the fuliginous mottling of the wing of the male (both 

 have the same large sub-basal fuligino-fuscous spot, seen also in Z. 

 ocularis Sauss.), is apparently undescribed, and occurs in Arizona, South-
