c After carefully examining a very large series of specimens of this species from 

 Mexico and Central America, I have concluded that the most logical course is to 

 restrict this form to specimens from the tierra caliente of southwestern Mexico. It 

 is true that some specimens from Yucatan and other parts of southeastern Mexico are 

 very nearly as pale as those from Guerrero, Sinaloa, etc., but they are always appre- 

 ciably different; and considering that from the same localities come specimens that 

 can not be distinguished from typical C. r. rvfipennis, whereas all specimens from the 

 western coast district are extremely uniform in their pale coloration, it seems to me 

 best to revise the respective ranges of these two forms as above. It is a great pleasure 

 to be able to say that this is the only instance in which my studies of the genus lead 

 me to a different conclusion from Mr. Todd s. 



<* Specimens from Putla and Tonala not seen by me, but I think it very likely that 

 the range oiC.r. eluta may extend along the arid Pacific coast district as^ar as Chiapas.
