Agromyza fumicosta n. sp. 



This species is very similar to longispinosa, differing only in being 

 slightly smaller, in having the antennae slightly larger, the bristles on 

 the mesonotum weaker ; the wings more obtuse, the second vein undu- 

 lated, the last section of fourth vein less than six times as long as the 

 penultimate section (7-1 in longispinosa) and the costa with a distinct 

 infuscation, which disappears before the lower margin of marginal 

 cell is reached. In all other respects, coloration and chaetotaxy, iden- 

 tical with longispinosa.

Agromyza felti new species. 



Male: Pale yellow, shining, ocellar spot and back of head black; 

 orbits slightly browned posteriorly ; arista brown or black ; other parts, 

 of head clear yellow. Mesonotum with a large black spot on disc which 

 is most intense on the area covered by the discal mark in melampyga 

 Loew ; the quadrate area between the posterior lobes is filled with a 

 less intense black color which extends almost to the scutellum and is 

 centrally dentate ; pleurae unspotted, or with a reddish triangular - 

 mark between fore and mid coxae, postnotum glossy black ; scutellum 

 with a small spot at base on each side. Abdomen with a brownish- 

 black fascia on each segment, the posterior margin yellow ; sixth seg- 

 ment elongated ; hypopygium normal in shape, blackened laterally. Legs 

 yellow, wings clear, veins distinct. Halteres yellow. 



Frontal orbits distinct; four pairs of orbital bristles present, the 

 lower pair rather weak, incurved; antennae as in melampyga; arista 

 closely covered with pubescence, giving it a rather thickened appearance, 

 its length not equal to that of frons; cheek about one-fifth as high 

 as eyes ; vibrissa weak. Four pairs of dorso-centrals on mesonotum, 

 which decrease in strength towards anterior margin; discal hairs 

 distinct. Abdomen as in melampyga. Legs of the normal shape; 

 mid-tibia without any posterior bristles. Wings almost identical in
