Front distinctly trisulcate, sparsely punctured, shinins; black, with 

 moderately long whitish pile more abundant between the lateral sutures 

 and the eye margin. Occiput opaque, white pubescent, except near the 

 eye margin, where it is shining olivaceous and pilose. Face shining black ; 

 viewed from in front, covered, except broadly on the tubercle, with very 

 fine pubescence (viewed from the side it appears bare); very deeply con- 

 cave below the antennae and indistinctly so below the tubercle, with a few 

 short hairs between the facial sutures and the eyes. Tubercle round, 

 subacute, shining, much more prominent than the antennal elevation, 

 situated below the middle of the face. Epistoma not projecting, in 

 profile obliquely truncate at apex, lower margin straight and horizontal. 

 Cheeks narrow, coloured and provided with pile like the face. Proboscis 

 large, flabellate, dark ferrugineous ; palpi cylindrical. Antennae and 

 narrow margin of the orifices bright reddish-fulvous, first joint slightly 

 darker, second with a few short dark bristles, third joint somewhat longer 

 than broad and a little flattened above and below, large and nearly oval. 

 Arista basal, black, micro-pubescent, not incrassate. Humeral callosities 

 ferrugineous, inwardly silvery poUinose. Dorsum slightly metallic, 

 sparsely punctured, more coarsely so posteriorly, with sparse erect light 

 yellow pile. Pleura shining olivaceous, with very sparse whitish pile. 

 Scutellum coarsely punctured, black, rather long pilose and with slightly 

 stronger hairs on the border. Abdomen robust, distinctly expanded on 

 segments two and three, sparsely but distinctly punctured, with short 

 sparse yellowish pile, everywhere shining except a broad median stripe 

 on the second segment. This stripe has a small shining area in its middle 

 anteriorly. There is a general, almost indiscexnable, purplish cast to the 

 abdomen. Venter shining, polished anteriorly, light yellowish pilose, the 

 apical margins of the segments reddish. Legs light fulvous, with moder- 

 ately long whitish-yellow pile ; middle and posterior coxa? black ; the 

 apical joint of all the tarsi, and a large spot on the outside of the posterior 

 tibiae, brownish. Claws black, pulvilli whitish. Wings hyaline, veins 

 testaceous, apical cross-vein parallel to the margin of wing, meeting 

 the third vein at an acute angle. Teguls and narrow base of the wing 

 distinctly yellowish. Long. Corp., ii mm.; L. alae., 8.5 mm.
