AHT. 7 REVISION OF COCCOPHAGUS — COMPEEE 101 



C . australiensis Girault is undoubtedly a synonym. In the col- 

 lection of the Citrus Experiment Station is a specimen labeled 

 " George Compere, No, 766, Perth, W. Australia, bred from Leca- 

 nium hesperidum."" Girault 's description was based on four females 

 from Perth with George Compere's No, 766, The specimen in our 

 collection is identical with the form known as C. lunulatus Howard 

 and presumably Girault's types are the same. 



C. scuteUaris (Dalman) is a remarkably stable species subject to 

 slight or no variation regardless of its habitat. Specimens in a 

 series from one locality or specimens in a series from Europe, Africa, 

 Australia, and America are remarkably uniform and except for 

 C. ishiii, new species there are no closely related species to cause 

 confusion. With the possible exception of Australia, C. lecanii 

 (Fitch), or one of its allied forms, occurs in company with G. scutel- 

 larls (Dalman) throughout its known range and these two para- 

 sites have in common at least two hosts, notably Coccus hesperi- 

 dum, Linnaeus and Saissetia oleae (Bernard), It is the assump- 

 tion that the world-wide distribution of the coccids was effected 

 through the interchange of nursery stock and that the parasites 

 were transported at the same time as inhabitants of the coccids 

 and were subsequently influenced by the same environmental factors. 

 On the basis of this reasoning, it is inconsistent to treat all the dif- 

 ferent geographical races of one form as a single species and to give 

 specific rank to the various geographical variants of the other form. 

 However, it is reliably established that more than one species is in- 

 volved in the C. lecanii complex and at present there is no way to 

 determine their genetical relationship and refer them to their 

 ancestral stock. 



Female. — Head and body black with the apical portion of scutel- 

 lum more or less extensively yellow or orange. Occasionally im- 

 perfectly colored specimens are encountered, the portions usually 

 black being brown or suffused with brownish. Extreme apex of 

 scutellum not infrequently blotched with black. Legs yellow or 

 orange yellow except middle and hind coxae and hind femora, which 

 are black. 



Scape of usual shape, slightly fusiform, about four times as long 

 as wide. Pedicel a trifle more than one and one-half times as long 

 as wide and about two-thirds as long as first funicle joint. First 

 funicle joint longest, slightly more than twice as long as wide; sec- 

 ond and third each successively slightly shorter and almost imper- 

 ceptibly wider so that the third is slightly less than one and one-half 

 times as long as wide. First club joint slightly the longest and 

 widest; slightly longer than wide and not quite as long as the pre- 

 ceding funicle joint. Second and third club joints each progres- 

 sively shorter and narrower (fig. 67).
