ART. 4 NEW PARASITIC HYMENOPTERA GAHAN 25 



To the list of synonyms of C. lecanii (Fitch) given by the writer'"' 

 should be added C. coccidis Girauit and C. cov.^peri Girault. The 

 types of coccidis which were reared from Coccus Tiesyeriduw. (Linnaeus) 

 at New Orleans, Louisiana, are merely slightly discolored specimens 

 of lecanii, the discoloration probably due to abnormal conditions in 

 the breeding cages in which they were reared. 



The types of cowperi which were reared from Stictococcus gowdeyi 

 Newstead, September 20, 1915, Nagunga, Uganda, Africa, by C. C. 

 Gowdey, difTer from typical lecanii only in that the wings appear to 

 be veiy slightly more densely ciliated and very faintly dusky, while 

 the fore and median femora are paler than in lecanii although slightly 

 washed with fuscous. In the National collection are three specimens, 

 agreeing in every way with the types of cowperi, reared from Saissetia 

 oleae (Bernard) at Capetown, South Africa, in May, 1910. Harold 

 Compere, of the California Citrus Experiment Station, recently sent 

 to the writer several specimens reared December 1, 1925, from 

 Saissetia oleae taken at Capetown by E. W. Rust. The latter speci- 

 mens agree with the types of cowperi in every way except that the 

 legs are colored as in typical lecanii. 



There seems to be no doubt that Girault's types and all of this 

 material from Saissetia oleae are the same species and the differences 

 between the wings of this African form and American representatives 

 of lecanii are so slight that it is believed the African specimens rep- 

 resent merely a variation or at most a geographical race of C lecanii 

 (Fitch). 



PHYSCUS DIASPIDIS (Howard) 



Encarsia diaspidis Howard, U. S. Dept. Agr. Bur. Ent. Tech. P-uU. 12, pt. 4, 



1907, p. 77.

1912, p. 155. 



As indicated by Doctor Howard in his original description, this 

 species is not an Encarsia. The writer is of the opinion, after exam- 

 ining the type, that it belongs in the genus Physcus where it differs 

 from all of the other species known to the writer by having the first 

 funicle joint in the female fully twice as long as pedicel and distinctly 

 the longest of the funicle joints. The mesoscutum is closely set with 

 rather coarse hairs and has a single pair of coarse setae at the pos- 

 terior margin. On each half of the scutellum are from seven to ten 

 stiff setae, its surface otherwise bare. 



While the antennae of the female are 7-jointed, those of the male 

 are 8-jointed. The male scape is rather short and distinctly expanded 

 beneath, about two and one-half times as long as broad; pedicel 

 about as long as broad ; first funicle joint distinctly thicker than the 

 pedicel, about three times as long as thick and one and one-half times 

 as long as the second; second and following joints to apex subequal
