65. COCCOPHAGUS ACANTHOSCELES Waterston 



Coccoplwgus acanthoccles Waterston, Bull. Ent. Res., vol. 7, 1916, p. 141, fig. 3. 



Specimens of this species have not been available for stud3^ The 

 original description is very precise and there should be no difficulty 

 in recognizing this species. It differs from all other predominantly 

 blackish species by having the pedicel longer than the first funicle 

 joint (10:7). 



66. COCCOPHAGUS ROBUSTUS. new species 



Plate 5, Figure S; Plate 9, Figure 64; Plate 11, Figure 122; Plate 13, 



Figures 160, 161 



This species is most closely allied to C. modestus Silvestri, C, spec- 

 tahilis, new species and C. speciosus, new species from which it is 

 easily separated by the hyaline wings, different antennal propor- 

 tions, and absence of stiff, coarse, suberect setae on the dorsal margin 

 of the hind tibiae. 



Female. — Frontovertex orange yellow; face and cheeks similarly 

 colored except for more or less fuscous suffusions which are more 

 pronounced on the latter. Antennae yellow with dusky sensoria. 

 Occiput mostly blackish. Thorax and abdomen black except the 

 median piece of the metanotum, which is yellow in sharp contrast. 

 Legs mostly black marked as follows with a variable amount of 

 yellow : apices of fore femora, ends of middle femora, apices of 

 hind femora, fore tibiae more or less generally, middle tibiae nar- 

 rowly at bases. Tarsi pallid with more or less dusky. 



Pedicel almost one and one-half times as long as wide, plainly 

 shorter than the first funicle joint. First funicle joint the longest, 

 about one and one-fourth times as long as wide; second and third 

 successively decreasing in length and increasing in width so that 

 the third is about one and one-half times as wide as long. The 

 thick third funicle joint is a good character for the recognition of 

 this species. First club joint subequal to the two following joints 

 and to the third funicle joint (fig. 64). 



Fore wings hyaline; cilia rather dense and coarse. Marginal 

 vein plainly longer than the submarginal; stigmal as shown in 

 Figure 122. 



Scutellum slightly wider than long and about as long as the 

 jnesoscutum. Abdomen apparently as long and as wide as the 

 thorax, broadly rounded at the apex. General proportions of body 

 as shown in Figure 8. 



Frontovertex with numerous, short, black setae. Setae of thorax 

 and abdomen as shown in Figure 8. Apex of middle tibia with 

 one long, curved black seta (fig. 161). Apex of hind tibia with 

 a pair of subequal strong setae beneath and a pair about one-half as 

 strong on the dorsum (fig. 160).
