We here select as type locality of ftiscus, Santa Fe, New Mexico. 

 The types have been destroyed, but before us are series from both 

 Albuquerque and Jemez Hot Springs, New Mexico, nearby localities 

 which safely prove the identity of Haldeman's species. 



Though Walker's description of cephalotes is virtually worthless, 

 Kirby has, through study of that type, placed Scudder's oculatus and 

 Brunner's hydrocephalus under that name. That these names are 

 absolute synonyms of fuscus (Scudder himself stated that his oculatus 

 might not be distinct from fasciatus of Thomas, which is unquestion- 

 ably synonymous with fuscus) we are convinced from study of the 

 type of oculatus, the description of hydrocephalus and the series of 

 undoubted fuscus before us. 



Thomas' fasciatus we find, from the remaining specimens of his 

 type series which are now before us, to be a synonym of fuscus. 



Saussure and Pictet have described comanchus from specimens 

 of the present species showing only minor differences in the spines of 

 the caudal tibiae. 



The present insect is the only species of the genus found in the 

 United States from the eastern edge of the great plain to the Sierras. 

 Adults are normally large, though not averaging as large as 5". longi- 

 spina. As we have remarked on page — , material in the instars pre- 

 ceding maturity shows the genitalia in both sexes in no way different 

 from the adult condition ; such material is here recorded as " nearly 

 adult." As we have already stated, some of these examples are re- 

 markably small and appear to indicate considerable size variation in
