TAXONOMY OF MUSCOIDEAN FLIES — TOWNSRND 65 



CEDEMAPEZA, gen. nov. 

 Type, Atroph. townsendi Williston. 



CATEMOPHRYS, gen. nov. 

 Type, Vanderwulpia sequens Townsend. 



BRAUERIMYIA, nom. gen. nov. 



Type, Wulpia Brauer and von Bergenstamm (1892), preocc. by 

 Bigot in Dipt. (1886). The genus is a valid one. The new name 

 is proposed as a tribute to the memory of Friedrich Brauer, the 

 one student who has most advanced our knowledge of the Mus- 

 coidean flies. 



Below is a table of these and certain allied genera. All of them 

 except Vanderwulpia, Brauerimyia, and Catemophrys have the para- 

 facial bristles continuous with frontal row. This character, how- 

 ever, does not seem to indicate close relationship in all cases, as it is 

 probable that Ceratomyiella, Metachceta, Dichocera, and Atrppho- 

 palpus, all here included, belong in other subfamilies from the rest. 

 Hypertrophocera and certain other genera not included in the table 

 possess this character. 



Frontal bristles stopping short at insertion of antennae, apical cell end- 

 ing well before wing-tip, stump of vein at bend of fourth, hind cross- 

 vein nearer bend of fourth, cheeks about one-third eye height, eyes 

 bare, arista pubescent basally, abdomen slender and rather conical, 

 macrochsetse only marginal 2 



Frontal bristles descending to middle of second antennal joint, apical 

 cell ending well before wing-tip closed or extremely short petiolate, 

 a black wrinkle but no stump at bend of fourth, hind crossvein nearer 

 to bend, cheeks about one-half eye height, eves bare, arista pubescent 

 basally. abdomen elongate, macrochsetse only marginal. 



Type, Vander. sequens Catemophrys, gen. nov. 



Frontal bristles descending on parafacials to lower border of eyes 3 



2. No costal spine, apical cell long petiolate, parafacials bare. 



Type, atrophopodoides I ' dhderwulpia 



A costal spine present, apical cell narrowly open or closed in margin, 

 parafacials distinctly very short pilose. 



Type, Wulpia aperta Brauerimyia 



3. Palpi atrophied, minute, apical cell closed in border at wing-tip, hind 



crossvein nearer bend, eyes almost bare. 



Type, angusticornis Atrophopalpus 



Palpi normal '. 4 



4. Eyes bare, a costal spine, cheeks not over one-fourth eye height; apical 



cell ending well before wing-tip, long petiolate: claws of both sexes 

 atrophied and tarsal joints compressed and swollen, arista pubescent
