268 MR. It. E. TURNER ON THE [Feb. 15, 



broad again as long, slightly rounded at the posterior angles, 

 shining, with large scattered punctures, the clypeus with a 

 carina. Thorax and median segment shining, very sparsely 

 punctured ; the pronotum narrower than the head, half as broad 

 again on the anterior margin as long, narrowed posteriorly, 

 no broader on the posterior margin than long ; scutellum short, 

 much broader than long. Median segment as long as two-thirds 

 of the pronotum, slightly broadened posteriorly and sharply 

 truncate. Abdomen broader than the thorax, sparsely punc- 

 tured, very finely at the base of the segments, more coarseiy 

 at the apex ; the first segment vertically truncate at the base, 

 the dorsal surface finely longitudinally striated between deep 

 scattered punctures ; the second segment finely and closely 

 longitudinally striated, the apical margin feebly raised, with a 

 narrow groove before it. Pygidium broad, not truncate or com- 

 pressed, longitudinally striated, broadly rounded at the apex, the 

 dorsal plate narrowed at the extreme apex. Ventral surface 

 shallowly but coarsely punctured, most finely on the fifth segment. 

 A minute spine on the mesopleura? close to the base of the inter- 

 mediate coxa?. Tarsal ungues bidentate. 



Fusco-ferruginous ; the head (except the mandibles and antenna?), 

 the scutellum, median segment, and stains near the apex of the 

 third, fourth, and fifth dorsal abdominal segments black. 



Length 13 mm.

Tachynomyia auricomata, sp. n. 



6 . Head punctured-rugose, clothed with long golden pubes- 

 cence, thin on the vertex, close on the clypeus, and forming the 

 usual fringe of long curved hairs on the cheeks ; the clypeus 

 slightly convex and more broadly truncate at the apex than 

 in most of the allied species. Antenna? as long as the thorax 

 and median segment combined, the apical joints feebly arcuate, 

 inserted nearer to each other than to the eyes ; the interantennal 

 prominence bilobed. Pronotum very shallowly punctured, the 

 remainder of the thorax and the pleura? more closely and deeply 

 punctured; the anterior margin of the pronotum raised, much 

 narrower than the head ; thorax with sparse golden, pleura? 

 with white pubescence. Median segment punctured-rugulose. 

 Abdomen shining, fusiform, very shallowly punctured, segments 

 2-4 with a faintly raised curved mark on each side near the apex ; 

 the first segment narrowed at the base, with a longitudinal sulcus 

 from the base to the middle, the second segment depressed at the 

 base. Hypopygium with the sides parallel close to the base, then 

 triangular, with a short apical spine. 



Black ; the apex of the mandibles, the femora, tibia?, and 

 tarsi ferruginous. Wings hyaline, nervures fuscous, the stigma 

 ferruginous. 



Length 10 mm.
