LAMB—DIPTERA: HETERONEURIDA, ORTALIDA, TRYPETIDA, SEPSIDA, ETC. 325 
Drosophilide. 
DrosopHita Fallen, Dipt. Suec., Geomyz., 4 (1823). 
Many species of this genus were collected, only two of which can be referred to known 
species from published descriptions. 
The genus is represented by a large variety of forms, some of which might well be 
considered subgenera or even genera, but as these are represented by single species it is 
thought best to merely indicate such possible divisions. 
For convenience of reference to what follows the species may be grouped as follows :— 
I. Species with costa to third vein (Leucophenga Mik.). 
sericea, p. 326. 
grossipalpis, p. 328. : 
II. Species with remarkably constricted waist and short wings. 
*notabilis, p. 329. 
*III. Species with a remarkable slit to the costa, the end provided with spines and 
bristles. 
fracticosta, p. 329. 
mgerrima, p. 331. 
nigrobrunnea, p. 332. 
IV. Species like Chymomyza : 
*punctiscutellata, p. 333. 
V. Species with remarkable transverse eyes : 
*aberrans, p. 334. 
VI. Species with remarkable spines on front tarsus : 
*spinipes, p. 336. 
VII. Species with curious curled hairs on front legs : 
*hirtipes, p. 337. 
VIII. Species with marmorated thorax. 
punctulata Loew, p. 339. 
jucunda, p. 339. 
*TX. Species with a distinct shining vertical triangle. 
Jimtima, p. 340. 
caliginosa, p. 341. 
pallipes, p. 342. 
triangulifer, p. 343. 
rufuloventer, p. 344. 
X. Species of ordinary pale form recalling melanogaster. 
nasuta, p. 346. 
melanogaster Mg., p. 347. 
similis, p. 347. 
It is highly probable that the species and groups marked thus * should be raised to 
generic or at least subgeneric rank, but as so few specimens are available, this course is 
not adopted.
