430 Miss G. Ricardo — A Revision of 



collections under B. curiar'ms. After carefully studying his 

 description of his new species I am convinced the above 

 specimens are identical with his species macrostylus and that 

 they do not belong to the genus Blephnrotes, though it is 

 very unlike Loevv to have overlooked the following characters 

 which preclude it from belonging to Blepharote.s , viz. : ovi- 

 positor of female, which is long and compressed at sides ; 

 short style of antennee and short third joint, the absence of 

 thick tuft-like hairs at sides of abdomen, and the very much 

 slighter build of legs; these last three characters were 

 noticed by Loew in his description, but of the ovipositor he 

 makes no mention. The neuration of ivings is very similar. 

 Small males of Blejjharotes flava have a slight general 

 resemblance to this species, but the thick tuft-like hairs at 

 sides of abdomen will at once distinguish them. 



This is a large species : abdomen fulvous with reddish- 

 yellow pubescence and black apex; tl lor ax h\dicY\^\\ ; wings 

 large, hyaline. Legs wholly black. 

 Length 27-35 mm. 



Male. — Face blackish, covered with yellowish tomentum ; 

 the tubercle large, occupying the lower part of face, bearing 

 the moustache composed of long white hairs. Palpi black, 

 with black hairs. Antennce black, the third joint with a long 

 terminal bristle ; the first two joints short, the first the 

 longest, both with black hairs ; the third conical, with a 

 rather long tapering point, the joint a little longer than the 

 first two joints together, the bristle nearly as long as the 

 joint. Forehead brownish black, with white pubescence, 

 white hairs on hind part of head, a few black hairs at vertex. 

 Thorax brownish black, with black pubescence and two long 

 bristles before the suture, two beyond, and several on 

 posterior ])art of thorax ; sides and breast with white pubes- 

 cence. iScutellum same colour, with tlu'ce stout bristles on 

 posterior border. Abdomen flat, rather broad compared with 

 Aailus species, at its widest about 5 mm., becoming narrower 

 at apex ; the first segment black with black pubescence, the 

 others bright reddish yellow with fulvous pubescence; sides 

 with fairly long, fine, yellowish-white hairs, thickest on the 

 second segment, not disposed as tufts ; posterior border of 

 last segment and the genital organs black, the latter large 

 and prominent with black pubescence ; underside black, 

 bare, with black hairs at sides. Legs blackish, all the femora 

 armed with black bristles ; coxse with long white hairs, 

 pubescence elsewhere and all bristles black. Wings hyaline, 

 the posterior branch of fork strongly curved ; the second 

 posterior cell broud at base, bulging into the tirst, the third
