ART. 7 EEVISION OF COCCOPHAGUS COMPERE 29 



Scutelliim slightly wider than long (6:5) and about as long as 

 the mesoscutum. Abdomen short, about as wide as long. As seen 

 through the abdominal' walls in balsam-mounted specimens, the 

 ovipositor arises near the middle, not exserted. 



Basitarsus of middle legs about as long as the four succeeding 

 joints united; tibial spur shorter than the basitarsus. Hind tibial 

 spurs unequal. 



Mesoscutum densely setose. Scutellum usually with two or three 

 small setae, similar in size to those of mesoscutum, scattered near 

 the anterior pair of bristles. Each parapsis with four or five setae. 



Measurements in mm. : Length of head and body, 1.0. Scape, 0.1488 

 long by 0.0360 wide. Pedicel, 0.0640 long by 0.0384 wide. First 

 funicle joint, 0.0760 long by 0.0496 wide; second, 0.0656 long by 0.0560 

 wide ; third, 0.0624 long by 0.0640 wide. First club joint, 0.0640 long 

 by 0.0688 wide ; second, 0.0576 long by 0.0664 wide ; third, 0.0616 long 

 by 0.0432 wide. Marginal vein, 0.25 long ; submarginal, 0.31 long. 



Type.— Cat No. 42093, U.S.N.M. 



Described from 14 females (holotype and paratypes) from collec- 

 tion of P. H. Timberlake with the following data on labels : " Bred 

 from Pulvinaria higeloviae CklL, collected at Murray Utah, June 7, 

 1914, by Timberlake; U. S. D. A. No. 14709E."

 pp. 2-A. 



A single male designated allotype taken in association with the 

 series of type females, led to the recognition of this form as a species 

 distinct from C. anthracinus Compere, for the males associated with 

 the latter were quite different. It is now thought that the males 

 associated with C. anthracinus belong to another species although 

 they were paired with females. It is believed, however, that 

 C. atratus is a distinct species even though the males of the two 

 forms are not greatly unlike as first supposed. 



In addition to the characters given in the original description that 

 supposedly separated the females of C. atratus from G. anthracinus 

 attention is called to the difference in venation as shown in the figures 

 of the stigmal and postmarginal veins (fig. 104). Also, in this spe- 

 cies the sixth tergite in proximity to the abdominal spiracles and a 

 more extensive area on the fifth tergite is marked as shown in Figure 

 166. In C. anthracinus and C. timberlakei these peculiar marks are 

 not evident.
