length; first four roughly twice as long as wide, apical two joints 

 more slender. 



Mesoscutum Avith a reduced number of setae posteriorly, only a 

 single strong pair near the posterior margin and anterior to these 

 another pair not quite so strong. Most species have about five 

 stronger setae in alignment along the parapsidal sutures, but this 

 species has only one seta anteriorly on either side. The anterior two- 

 thirds of the mesoscutum with moderately strong, sparse setae. Each 

 parapsis with three setae. Each axilla with two setae. 



Length about 0.68 mm. 



liedescribed from two females and one male (cotype) U.S.N.M. 

 No. 20002, labeled, " Bred from Lecanium corni, Madison, Wis., June 

 22, 1915, F. A. Fenton." One female is obscured under the excess 

 of balsam squeezed out under the cover glass, the other is crushed. 

 The male specimen is in the best condition but the antennae are 

 partly concealed.

The type female has been crushed beneath the cover glass but the 

 important structural characters are to be seen as shown in Figure 

 136. The species can be recognized by the unusual wings as shown 

 in Figure 76, and by the transverse scutellum. The wings of this spe- 

 cies are unlike those of any other described species of Coccophagus. 



Scape obscured beneath head but apparently about as shown in 

 Figure 47. Pedicel slightly longer than wide and about as long as 

 first funicle joint. Funicle joints ventrally articulated, all slightly 

 longer than wide and about of same size and shape. Club as long 

 as funicle joints combined and about one and one-half times as wide 

 as distal funicle joint. 



The character of the fore wing is best shown by the illustration, 

 Figure 76. The wing from which the drawing was made is twisted 

 at the base. The center of the Aving is occupied by a slightly infus- 

 cated area, which is clothed with blackish cilia. The shape of tins 

 area is shown in the figure. Distad of the infuscated area the cilia 

 are very fine and transparent. Marginal fringe long. Marginal 

 vein as long as submarginal vein; stigmal and postmarginal as 

 shown in Figure 106. 



Thorax about as shov/n in Figure 136. The setae are rather 

 coarse and blackish so as to be easily seen. Mesoscutum with a'X)ut 

 40 setae, of about the same size as those on the axillae and the
