Akticle VII. — Firxf Supplement to the Check-List of the 

 Coceidce. By T. I), A. Cockerell, New Mexico Acjricnl- 

 tural Kxper'nnciit Sini'ion. 



Since the publication of the Check-List* in 1896 no less 

 than three hundred and twenty-two species have been added. 

 A few of these are old species Avhich had been accidentally 

 omitted or improperly reduced to synonyms, but the number 

 of actually new species is very great, and bears witness to 

 the activity of coccidologists. Forty species, given as valid 

 in the Check-List, are here reduced to varieties or synonyms. 

 As before, I have included a number of names of species 

 (mostly by Green) which I know to be either in press or 

 awaiting very early pul)lication. 



The group IdiocorciUfC has l)een abandoned and merged 

 into Cocci lue. The Cocciiuc could very well be divided into 

 two subfamilies and perhaps four tribes, as follows : 

 (A.) Cocciiue. Xewdy hatched larva with rows of dorsal spines, 

 and the last antennal joint usually short. 

 (1.) Coccini. Anal ring hairless. {Coccn><, etc.) 

 (2.) Er'wcoccin'i. Anal ring hairy, hairs normally 8. 

 {Ei-iococciia, etc.) 

 (B.) Ddctijlopiime. Newly hatched larva without dorsal 

 spines, last antennal joint usually long. 

 (1.) Sphd'vococc'nii . Anal ring hairless. [Spherococcm^.) 

 (2.) Dacti/lopiini. Anal ring hairy, hairs normally G. 

 (Thictylopuix, etc.) 



Species which were in the original list, here repeated to 

 indicate varieties, synonyms, etc., have the original numbers. 



Since the Check-List was written, the following new writers 

 have described and named Coccuhe. To facilitate corre- 

 spondence I give their addresses : 



Bogue, E. E., Stillwater, Oklahoma. 



Cooley, E. A., Agricultural College, Amherst, Mass.
