COCCID^E 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- 

 tions duly noted) in working over the two lots of coccid material col- 

 lected in Mexico by Messrs. Townsend andKoebele during 1897, which 

 were sent to us for determination by the United States Department of 

 Agriculture. An author's initials, bracketed at the end of a species, 

 mean that the entire text under that species is to be accredited to that 

 author alone. The work of mounting the specimens, drawing up the 

 descriptions, and finally of preparing and writing the entire manuscript, 

 was done by Mr. Townsend. Some notes on the forms of Icerya pur- 

 chasi, based on material not represented in the above two lots, and also 

 the description of a Brazilian species of Capulinia, are included in the 

 paper, having developed in connection with the study of the other 

 material. 



Icerya purchasi Mask. 



Typical form (= crawl Ckll.). — On citrus trees in Magdalena, So- 

 nora, Sept. , 1894 (Townsend). Thriving colonies of the typical pur- 

 chasi were found here, and must have been introduced from California. 

 This, however, is so far the only authentic recorded locality for typical 

 purchasi in Mexico. (See remarks under var. maskelli which follows.)
