Key to the Species of Mumetopia. 



Front tibiae and first three joints of front tarsi black; face less than one 

 fourth as broad as the front at its middle. 1.2 mm. (Porto Rico.) 

 (Anthomysa.) nigrimana Coquillett. 



Legs yellow, at most the last tarsal joint black; face about one half as broad 

 as the front at its middle 2. 



2. Occiput with a white-pruinose spot above the neck ; sides of mesonotum 



thinly white pruinose; pleurae largely yellow; last tarsal joint not 

 black; face white; mouth-parts yellow. 1.75 mm. (Ga.,* La.,* Tex.*) 



occipitalis new species. 



Occiput, notum, pleurae and abdomen entirely polished black ; last tarsal 



joint black, contrasting with the remainder of the legs 3. 



3. Clypeus, palpi and base of proboscis black ; center of face dusky ; third 



antennal joint infuscated above. 2.5 mm. ( Mass. *).ni7^w.x new species. 



Mouth-parts entirely yellow ; face white ; third antennal joint white. 2 



mm. (N. H.) (Anthomysa.) terminalis Loew. 



Mumetopia occipitalis new species. 



Length 1.75 mm. Front black, next to the antennse yellowish, which be- 

 comes whitish pollinose and broader on the orbits ; face and cheeks white ; 

 occiput black except along the oral margin, marked with a silvery white prui- 

 nose spot just above the neck. Antennae yellow, the third joint mostly white 

 and white-hairy, infuscated only at the insertion of the long-pubescent black 

 arista. Mouth-parts, including the small clypeus, yellow. Width of face one 

 half the width of the front at its middle. A single pronounced fronto-orbital 

 located beyond the middle of the front, with sometimes a minute bristle imme- 

 diately before it. Mesonotum and abdomen shining, though very little dusted, 

 black, the sides of the mesonotum yellowish overlaid with white pruinosity ; 

 pleurae yellow, but with a horizontal blackish line just below the notopleural 

 suture; two dorsocentrals, acrostichals almost entirely wanting. Halteres and 

 legs light yellow. Wings narrow, hyaline, the veins yellow. 



Seven specimens: Austin, Texas (February to November), and 

 Opelousas, Louisiana (March). Those from the latter place w^ere 

 received from Dr. Hough determined as terminalis Loew. 



Mumetopia nitens new species. 



Length 2.5 mm. Shining black, the front above the antennae, facial orbits, 

 labella, halteres, and the legs, except the last tarsal joint, light yellow. The 

 narrow buccae continuing as the facialia nearly to the antennae black ; the cen- 

 ter of the face dusky ; the large clypeus and the palpi black. Antennae yellow, 

 the third joint dusky above; the black arista with rather long pubescence. 

 The width of the face at its middle somewhat more than one half the width 

 of the middle of the front. Near the middle of the front is a stout fronto- 

 orbital, and towards the level of the antennae is another, about one half the 

 length of the former. Two dorsocentrals and four rows of fine but distinct
