i 9 and 3 $ specimens, Mendoza and Bahia Blanca, Argen- 

 tina (L. Bruner). Collection University of Nebraska. 



In the coloration and markings of the head and mesothorax 

 this species resembles C. lugubris F. Smith, but differs in hav- 

 ing all the femora entirely black and in its greater size. 



Gaupolicana fulvicollis Spinola. 



The S of this species, besides the usual sexual characters, 

 differs from the 9 in having a white fascia on the fifth dorsal 

 segment, and in having the first four ventral segments clothed 

 with long thin silvery white hairs. In both sexes the pubes- 

 cence on the first dorsal segment varies from pale fulvous to 

 grayish white, and in no case are the tibiae and tarsi clothed with 

 black pubescence as in C. gayi Spinola, but are bright fulvous, 

 the tibiae sometimes with a few white hairs on the inner side. 

 The intermediate and posterior femora are usually white, but 

 the anterior femora are concolorous with the thorax. 



Dr. H. Friese, in his monograph of the genus in 1898, ex- 

 presses some doubt as to whether this form is entitled to 

 specific rank, and thinks that it may be a variety of C. gayi 

 Spinola. The $ was unknown to him, and differs from 

 Friese' s description of the $ of the C. gayi in having a white 

 fascia on the fifth dorsal segment. This, with other minor 

 characters, such as color of pubescence on legs, etc., is suf- 

 ficiently characteristic to make it distinct. 



5$ and 4 9 specimens, Cacaraua, Argentina (L. Bruner). 

 Collection University of Nebraska. 



Caupolicana nigriventris Friese. 



One $ specimen I have identified as this species, but the 

 white fasciae on the third and fourth segments are wanting 

 on the disc, showing only on the posterior corners of the 

 segments. Probably worn off. 



Bahia Blanca, Argentina (L. Bruner). Collection Univer- 

 sity of Nebraska. 



Caupolicana albiventris Friese. 



A single $ specimen which agrees with Dr. Friese 's des- 

 cription in every particular. 



Arequipa, Peru, Oct. 28th, 1898 (A. G. Weeks). Collec-
