February, '16] COCKERELL: NEW COCCID.E 235 



Unfortunately a more specific determination of the insects found 

 to be carriers of polyhedra cannot be given at this time. The nature 

 of the experiment made it impracticable to determine the specimens 

 until after they had been examined for polyhedra. After examination, 

 many were badly mutilated, and owing to a misunderstanding were 

 discarded. It is to be remembered that the work done was only pre- 

 liminary and was planned to indicate whether insects ever acted as 

 carriers of polyhedra. Now that it has been clearly shown that they 

 commonly do carry polyhedra, it is expected to continue the work 

 another season and among other things to determine more definitely 

 the insects acting in that capacity. 



To sum up, little is known of how the infection causing the wilt 

 disease of the gipsy moth is distributed. It is evidently not pri- 

 marily a wind-borne disease. Certain insects found abundantly in 

 association with the disease, frequent the foHage of trees and are known 

 to carry polyhedra after contact with the wilt, which indicates that 

 they may assist in spreading the infection. 



TWO NEW MONOPHLEBINE COCCIDiE FROM THE 

 PHILIPPINE ISLANDS 



By T. D. A. CocKERELL, Boulder, Colorado. 



The Philippine Islands appear to be quite rich in Monophlebines; 

 in addition to six species already recorded (all but one apparently 

 endemic), the following two, received from Prof. C. F. Baker, must be 



described: 



Llaveia benguetensis n. sp. 



Male. — Length 4.5 mm., exclusive of abdominal processes; wings about 7 mm. 

 long, black, with the usual venation and two hyaline lines; costal field dark reddish- 

 brown; head and thorax black, the mesothorax shining, region just below wings dark 

 red and duU; mesosternum enlarged, convex, polished black; eyes very prominent, 

 constricted at base, placed at lower anterior corners of head; antennae black, with 

 very long black hairs; third joint with three nodes; legs black; abdomen broad, 

 dark red, with the dorsal region strongly suffused with black, apex deeply emarginate; 

 six long slender fleshy abdominal processes, the first pair shorter than the others, 

 which are subequal, and are a Httle longer than the diameter of abdomen. 



Hab. — Baguio, Benguet (Baker 5341). Resembles the Indian L. stebbingi (green), 

 but is not at all dusted with mealy powder, and the distance between the second and 

 third abdominal processes at base is very much greater. L. fabricii (Westwood), 

 from Sumatra, is apparently, as Green remarks, another species of the same general 

 type. 



Drosicha palavanica n. sp. 



Male. — Length about 3.5 mm., exclusive of abdominal processes; wings nearly 

 5 mm. long, black, mth the usual venation and two hyaline lines; costal field dark
