AET. 7 REVISIOISr OF COCCOPHAGUS COMPERE 61 



Middle tibiae entirely yellow. Hind tibiae more or less extensively 

 fuscous at base, the apical half or so yellow, the two colors gradually 

 blending without a sharp line of demarcation. Apical tarsal joints 

 fuscous, the other tarsal joints yellow. 



Usually the flagellura has fewer sensoria than is commonly seen 

 in the related African species. As seen from one side, on each joint 

 of the funicle two sensoria are usually sharply defined in one focal 

 plane; the first and second club joints usually show three sensoria, 

 while the third joint shows one. In the African forms the sensoria 

 are more numerous and closer together so that in one focal plane 

 three and four sensoria can be clearly seen on the funicle joints. 

 The antennal differences are not at all constant and can not be relied 

 upon unless taken in combination with other characters. 



As a rule the fore wings are less densely setose and the setae are 

 finer than in the African forms. As with the antennal differences, 

 the character of the wings is variable. 



Male. — Face, cheeks, frontovertex, antennal scape, and pedicel fus- 

 cous. Flagellum yellow. All coxae black, all trochanters yellowish. 

 All femora mostly black, the ends yellow. Fore and middle tibiae 

 yellow. Hind tibiae suffused at base with more or less blackish, the 

 remainder yellow. Apical tarsal joint fuscous, the other tarsal 

 joints yellow. Entire thorax and abdomen black. 



Goccofhagus californicus Howard is undoubtedly another syn- 

 onym of C. lecanii (Fitch). The type female is mounted in balsam 

 on a slide and crushed. If the under side of the specimen is viewed 

 in a subdued light or against a dark background the coloration ap- 

 pears exactly as described by Howard, namely " mesoscutellum lighter 

 in color than the rest of the thorax, except at immediate base, its 

 posterior edge with a narrow band of bright lemon yellow extending 

 from one lateral angle around the curved border to the opposite 

 lateral angle, of nearly equal width throughout, at its widest portion 

 measuring 0.027 mm." This appearance of distinctive coloration is 

 due to a difference of refraction caused by a deposit of body fluids 

 that accumulated and dried around the apical curvature of the 

 scutellum when the specimen was crushed. So far as can be seen, 

 the type female does not otherwise differ from typical specimens of 

 C. lecanii from California. Actually the apical two-thirds of the 

 scutellum is yellow with the basal third blackish.
