COCCID^ OF THE PHILIPPINE ISLANDS ^ 

 By Elizabeth Robinson 



SIX PLATES 



This paper is intended to bring together all obtainable in- 

 formation concerning the known species and available specimens 

 of Philippine Coccidae. For the advantage of the general ento- 

 mologist and the specialist in Coccidse it was believed advisable 

 to undertake a synoptic treatment of this family of Hemiptera. 

 From the collections of Prof. C. F. Baker, which were sent 

 to Prof. T. D. A. Cockerell, many species have been determined. 

 It is evident that the available specimens represent only a few 

 of the great number of Coccidse to be found in the Philippine 

 Islands. With few exceptions those studied have come from 

 Luzon Island. 



I take this opportunity to express my sincere thanks to those 

 who have aided me — especially to Professor Cockerell, under 

 whose direction the entire study has been made, and to Professor 

 Baker for specimens and for a list of food plants and biblio- 

 graphies of Philippine Coccidse.

' The Tachardiinae, or lac insects, will probably be found to occur in the 

 Philippines. Tachardia aiirantiaca Ckll. occurs in Java on Citrus, Fla- 

 courtia, and Albizzia. — Cockerell.
