COCCIDiE COLLECTED IN MEXICO BY MESSRS. 
TOWNSEND AND KOEBELE IN 1897. 
By C. H. Tyler Townsend and T. D. A. Cockerell. 
The following are species jointly studied by us (with certain excep- 
ions duly noted) in working over the two lots of coccid material col- 
ected in Mexico by Messrs. Townsend andKoebele during 1897, which 
vere sent to us for determination by the United States Department of 
Agriculture. An author s initials, bracketed at the end of a species, 
nean that the entire text under that species is to be accredited to that 
.uthor alone. The work of mounting the specimens, drawing up the 
lescriptions, and finally of preparing and writing the entire manuscript, 
/as done by Mr. Townsend. Some notes on the forms of leery a pur- 
hasi, based on material not represented in the above two lots, and also 
he description of a Brazilian species of Capulinia , are included in the 
•aper, having developed in connection with the study of the other 
material. 
eery a purchasi Mask. 
Typical form (= crawl Ckll.).—On citrus trees in Magdalena, So- 
ora, Sept., 1894 (Townsend). Thriving colonies of the typical pur- 
hasi were found here, and must have been introduced from California, 
’his, however, is so far the only authentic recorded locality for typical 
urchasi in Mexico. (See remarks under var. maskelli which follows )
