the sides of the true front.* Clypeiis and labrum scarcely distinct, 

 very short and transverse (labium and palpi uncertain). Pronotum 

 short and transverse. Abdomen short and slender. Legs slender ; 

 first tarsal joint equalling all the others united, 5th as long as the 

 2nd to 4th miited. Anterior wings transparent (of the form usual 

 in the Old World species with transparent wmgs), network rather 

 close. Posterior wings very long, narrowly tape-like, not dilated 

 towards the end (but twisted, as is usual), not conspicuously cihated. 



StenotcBTiia Walkeri, n. s.f 



Antennae about 43-jointed, black, the basal two joints yellowish 

 beneath. Head deeply bisinuate posteriorly above ; yellow, a broad 

 transverse blackish brown band above, behmd the antennae, a very 

 broad band of same colom' in which the antennae are inserted 

 (leaving only a narrow yellow line between it and the band on the 

 vertex) ; front yellow ; orbits yellow ; the posterior portion of the 

 top of the head brownish in the sinuations. Pronotum yellow ; at 

 about one-third of its length the posterior portion is strongly 

 separated fr'om the anterior by an elevated ridge, leaving a 

 depressed transverse collar, slightly clouded with brownish ; the 

 posterior portion with a large median, and two smaller lateral, 

 brownish black spots, and the deflexed sides are also broadly of the 

 same colour ; there are also numerous small brown dots, whence 

 arise short black hafrs. Meso- and meta-nota blackish, with short 

 black hairs, but the inner sides of the lateral lobes of the mesonotum 

 and the scutellum of the metauotum (excepting in its centre) are 

 yellow. Breast and sides of thorax yellow, varied with brown. 

 Abdomen ( ^ ) yellow, above with a narrow black longitudinal 

 median line, and a broad lateral black band (leaving only narrow 

 subdorsal yellow lines) ; beneath it is wholly yellow, excepting a 

 narrow lateral blackish line below the lateral sutures, and there are 

 numerous small semituberculate black dots, whence spring black 

 hairs : terminal dorsal segment blackish in the middle, clothed with 

 long black hairs, triangularly excised in its posterior margin; 

 appendages stout, cylindrical, very obtuse, somewhat conical if 

 viewed laterally, shghtly incurved, yellow, with a blackish spot 

 externally, furnished with long black hairs : terminal ventral 

 segment large, yellow, furnished and fringed with long black hairs, 

 its apical margin rounded; it is deeply concave if viewed from 



■■' Savigny's figure indicates precisely analogous foveae as existing 

 in the Egyptian species on which Kambur founded *^ Br achy stoma," 

 and an approach towards a similar structm-e, but much less pro- 

 nounced, occurs in others.
