of body li to 2 lines. Velvet black. Head, proboscis and 

 antennae black ; frons dusted with silvery white. Thorax on each 

 side above with a white mark in the shape of a hook, of which the 

 broader and shorter part is situated on the transverse suture, and 

 the longer and thinner part reaches to above the base of the wings. 

 Pleurae dull blackish, with four large shining white spots, of which

cue is placed higher than the others, in front of the base of the 

 wing, the three others being lower, and in a horizontal row. On 

 each abdominal segment is a very large triangular spot reaching 

 nearly to the posterior margin, and of a shining pearl colour, with 

 brilliant shining silvery reflections. Hypopygium velvet black, 

 only the claspers a little paler, the last joint of simple structure. 

 Legs blackish ; femora brownish yellow towards the base. Halteres 

 brownish . yellow with black clubs. Wings hyaline, moderately 

 large, costa very black, the longitudinal veins blackish, the 1st 

 longitudinal thicker, the rest distinctly less strong, the last one 

 not attaining the border of the wing." 



Length 3-4 millim. 



Cetlon. 



Genus APISTOMYIA, Big. 

 Apistomyia, Bigot, Ann. See. Ent. France, (4) ii, p. 109 (1862). 



Genotype, A. elegans, Big., the original and only other species. 



Head very rounded ; eyes pubescent, separated in both sexes by 

 a broad frons, and divided by an unfacetted band, as in Ble2iharo- 

 cera, separating the large upper facets from the small lower ones ; 

 three ocelli. Palpi probably 5-joiiited.* Antennae of nine (?) or ten 

 joints, barely longer than the head, bai-e ; 1st scapal joint short, 

 2nd inuch longer ; tlagellum of seven (?) or eight joints, of which the 

 first is the longest, the last ovate, and the intermediate ones short 



* In his text Bigot says that the palpi are tliree-jointed (adrling that they 

 were not clearly visible), but in his illustration the palpi are five-joiuted and 

 exceedingly long, and Kellogg reproduces this figure. In my new species I 

 can only assume that these organs have been broken off ; otherwise it possesses 

 only one-jointed palpi, a complete anomaly, which would of course necessitate 

 a new genus.
