 Africa. By Dr. J. VILLENEUVE. 



GEN. STOMOXYS, Geoff r. 



STOMOXYS TRANSVITTATA, u. sp. 



Sat laete ciuerea ; fronte quam oculo latiore ; thoracis dorso maculis 

 duabus, et, pone suturam, vitta transversa lata atque postice deutata, 

 atris ; abdomiue vitta medio-dorsali limboque segmentorum apicali 

 iiigris. Palpis flavis pedibusque brunueis, tarsis uigris, tibiis basi 

 plus minusve testaceis. Loug. 6| mm. 



Frons with parallel sides, its width hardly equals that of the eye 

 seen from above. Median band wide, very dark black, showing in 

 front of the ocellary ground a narrow but somewhat deep emargination 

 continued in a fine ashy line. Orbital part narrow, not shiny, ashy 

 white, genae similar and with a whitish sheen ; epistome with a dark 

 sheen ; peristome linear. Antennae black, moderately white, 3rd joint 

 nearly four times as long as the 2nd, which is very short, arista dark. 

 Palpi cylindrical, yellow ; reaching the anterior edge of the mouth, 

 pipette shiny black. Thorax light cinereous, with intense black 

 markings, resembling in this respect certain species of Limnophora ; in . 

 front are two spots in the shape of an upturned axe ; behind the suture 

 and connected with it is a wide transverse band reaching the base of 

 both wings, the anterior edge is straight, the posterior twice emargin- 

 ate, a fine ashy line intersects this baud in the centre. Scutellum 

 blackish, with an ashy spot on each side of the apex. Abdomen ashy 

 on the first segment which is edged with black behind and on the 

 sides, and with a median black line ; the other segments are grey ; 

 segments 2 and 3 bear a medio-dorsal baud and a wide posterior baud 

 narrowed in the centre, these bands are black ; segment 4 shows to the 

 right and left of the median part a longitudinal dark reflection. 

 Wings hyaline, halteres pale yellow. Legs brown, tarsi black, tibiae 

 testaceous in the proximal third part of the length ; this colour often 

 stretches along the external border.
