CIMBOCERA PAUPER Horn. 



Table of varieties. 



1. Abdomen with first suture slightly angulate, but the secona segment not greatly 



longer at the middle than on the sides, second segment laterally subequal to the 

 third and fourth segments together. 

 a'. Nasal plate glabrous broadly rounded behind, slightly emarginate at apex. 



Beak sulcate. Pubescence long var. pauper Horn. 



a^. Nasal plate obsolete; beak smooth, not sulcate. Pubescence long. 



var. sericea, new variety. 



2. Abdomen with first suture more strongly angulate, second segment longer than the 



two following together. Nasal plate obsolete; beak smooth or sulcate. Pu- 

 bescence long var. conspersa Fall. 



Thie characters which separate these geographical varieties or races 

 are entirely too fine for specific characters, and as variations are to be 

 found in the obsoleteness of the nasal plate, the appearance of the 

 seventh funicular joint, the smoothness of the beak, the relative 

 length of the abdominal segments, and the degree of arcuation of the 

 first suture, it is with hesitancy that the writer even ascribes the value 

 of local varieties to them. 



CIMBOCERA PAUPER PAUPER Horn. 



The species was described from "Dacota." A series of seven speci- 

 mens from Cheyenne, Wyoming, answer the description perfectly. 

 This locality belongs to the old Territory of "Dacota." 



CIMBOCERA PAUPER SERICEA, new variety. 



In the material at hand this northern mountain form is much more 

 mottled than the typical variety and has a white median vitta on the 

 prothorax. The tj^pical locahty must be considered as American 

 Fork Canon, Utah, from which 13 specimens are at hand. The mate- 

 rial also includes 1 specimen from Helena, Montana, 10 from Canon 

 City, 2 from Garland, and 1 from Grand Valley, Colorado. The latter 

 was taken by H. F. Collier, April 5, 1911, injuring apple twigs. 



Type.— Cat. No. 14633, U.S.Nat.Mus. 



CIMBOCERA PAUPER CONSPERSA Fall. 



Cimbocera conspersa Fall. 



This form was described from Santa Fe, and San Ildefonso, New 

 Mexico. Material is at hand from Santa Fe, Gallup, Las Vegas, and 

 Albuquerque, New Mexico, and from Winslow, Bright Angel Hotel 

 (run of Colorado Caiion), and Holbrook, Arizona. 



At Bright Angel this form was taken on pinon trees {Pinus edulus). 



Genus MILODERES Casey (1888). 

 Milodores Casey, Ann. New York Acad. Sci., vol. 4, 1888, p. 252. 



The genus was monotypic, based on setosus Casey.
