lowing synopsis of the genera, in the hopes that it may be of 

 service to others. 



Sapromyzinae. — Small species, seldom more than seven millimeters in 

 length. Head as broad or a little broader than the thorax; front with one 

 or two bristles on each side in front of those at the vertex. Antennae 

 usually short and porrect; sometimes the third joint elongated. Face 

 without vibrissae. Abdomen short-ovate. Legs never elongate; auxiliary 

 vein of the wings present; cross-veins never approximated; basal cells 

 small, but complete. 



I. — All the tibiae with a preapical bristle ; ovipositor flattened, horny; 

 bristles of the front never reaching below the middle .... 2. 

 All the tibiae, or at least the front and middle pairs, with a preapical 

 bristle ; bristles of the front descending below the middle; ovi- 

 positor not horny 3. 



2. — Metallic black species, front narrow Lonchaea, 



Yellow, or yellowish species; front broad Palloptera. 



3. — Arista thickened and with short, dense plumosity . . Pachycerina. 



Arista slender, base, pubescent or plumose 4. 



4. — Face very broad, in profile strongly convex below . . Physogenua. 



Face receding, flattened, or gently arched 5. 



5. — First posterior cell much narrowed in the margin . . Griphoneura. 

 First posterior cell not or but slightly narrowed in the margin . . 6. 

 6. — Shining black species; third joint of antennae more or less elongate. 



Lanxania. 



More or less yellow species, at least the thorax not shining black; 



third joint of the antennae not more than three times as long as 



wide Sapromyza. 



* 

 Sapromyza longipennis, S. hipulina, S. vulgaris and S. com- 



pedita, occur on the Pacific coast, at least all but the first, which 

 I have seen from Kansas. 6". vtilgaris I have also taken from 

 the West Indies. It is identical with kS". ocellaris Towns. , and, 

 notwithstanding the abdominal bands, is doubtfully distinct from 

 6". cinda from Texas and Porto Rico (Roeder). 6*. macula Loevv 

 seems to be the same as ^. odopioicta from the West Indies and 

 South America. 6". plagosa Giglio-Tos. from Mexico, is the 

 same as vS. geminata Wied., which I have from Brazil. Pallop- 

 tera jucunda Loew, from Sitkha, occurs also in Washington and 

 California. Sapromyza urina Giglio-Tos, from Mexico, seems 

 identical with Physogenua ferrugiiiea Schiner, which I have from 

 Brazil. In any event, it is a Physogenua and not a Sapromyza. 

 Pachycerina verticalis Loew apparently extends over the greater 

 part of the United States. I have seen it from Florida, Connec- 

 ticut and Kansas.
