20. COCCOPHAGUS SPECIALIS, new species 



Plate 7, Figure 33 



This unusual species has the habitus of Euxaiithellus. Wings, hya- 

 line, the cilia translucent and abnormally long and dense basally. 

 Predominantly yellow. Abdomen on either side with two longi- 

 tudinal rows of brown dots, which on the outer rows coalesce or are 

 contiguous so as to form a more or less continuous stripe. First 

 funicle joint about three times as long as wide. 



Female. — Face and cheeks white, in life probably iridescent pearly 

 white. Frontovertex orange blotched with iridescent pearly white 

 contiguous to the ocelli. Eyes and ocelli reddish. Center of occiput 

 and a transverse band on either side of the foramen blackish. Con- 

 cealed part of pronotum and a spot on either posterior angle blackish. 

 Thorax lemon yellow; propodeum near spiracles iridescent pearly 

 white. Middle of abdomen on dorsum more or less yellowish, the 

 sides widely marked with iridescent pearly white interrupted by 

 elongated brownish spots. Legs pale yellowish; first and second 

 tarsal joints of hind legs fuscous, those of the middle legs slightly 

 fuscous ; remaining tarsi of middle and hind legs yellow to whitish ; 

 first three or four tarsal joints of fore legs more or less faintly 

 fuscous, apical joints pale, claws fuscous. 



The antennae are mounted so that the scape can not be accurately 

 viewed but apparently the scape is longer than usual. Pedicel 

 almost twice as long as wide, plainly shorter than the first funicle 

 joint. First funicle joint plainly the longest, about three times as 

 long as wide; second and third successively decrease in length and 

 slightly increase in width so that the third is about one and one-half 

 times as long as wide. Club large, all joints a trifle longer than 

 wide (fig. 33). 



Fore wings clothed with translucent, " silky " cilia. Marginal 

 vein as long as the submarginal ; postmarginal produced as far distad 

 as the apex of stigmal. Wing veins pale. 



Frontovertex slightly wider than long (8 : 7) and one-half as wide 

 as the head (8 : 16). Head plainly much wider than the mesoscutum 

 (16:11). Mesoscutum moderately long. Scutellum wider than 

 long (8:6) and shorter than the mesoscutum (6:8). Scutellum 

 squarely truncate at apex; somewhat hexagonal. Median piece of 

 metanotum, distinct, well developed appearing like an apical part 

 of scutellum separated by a broad cross suture. Like C. triguttatus 

 Girault, this species presents conspicuous bulged mesopleura that are 

 translucent showing the transverse striae. Abdomen plainly shorter 

 than the thorax, slightly wider than long (32:27), the lateral curva- 

 tures from base to apex almost uniform; as seen through the derm 

 the ovipositor arises under the posterior margin of the third tergite 

 and very slightly projects at the apex.
