third of eye-height, and the apical cell ends almost in wing-tip. The 

 macrochaetae of abdomen are only marginal in both genera. 

 Reproductive habit unknown. 



Type: Acemyia tibialis Coq., Rev. Tach., p. 116. 



Acemyia acuticornis Meig. had been reared in Europe 

 from Acridium, Acemyia dentata Coq., which is not at all 

 typical of the genus, having the apical cell closed and ending 

 well before wing-tip, and the eyes in female descending almost 

 to the level of the vibrissae, has been reared in North America 

 from Melanoplus and Chortophaga. 



Doryphorophaga, gen. nov. 



Erected for Lydella doryphorcs Riley. It belongs with the compsi- 

 lurine flies, and bears a strong general resemblance to Compsilura con- 

 cinnata. The eyes are thickly hairy, the facialia are ciliate on about 

 lower two-thirds, the bend of fourth vein is without stump or wrinkle, the 

 intermediate abdominal segments bear discal bristles, and the ventral 

 carina and curved spine-like piercer, both of ordinary character, are present 

 in the female. It differs from Compsilura principally in having the second 

 antennal joint noticeably elongate, and the parafacials widened. Differs 

 from Lydella and De.rodes in the thickly hairy eyes, ciliate facialia, and 

 frontal bristles not descending low; from Incamyia in the last character 

 and the ordinary ventral carina; and from Eucelatoria in the hairy eyes 

 and the elongate second antennal joint. 



Reproductive habit, subcutaneous larviposition in host. The uterus 

 is long, slender, and coiled, and develops white maggots in single file to 

 the number of about 150. The maggot has well-developed rows of micro- 

 scopic spines, of which the first three rows and the last row encircle the body, 

 the intermediate six rows being on ventral surface and about half encircling 

 the body. (TD370, coll. by D. H. demons, Aug. 17, 1908, Melrose 'High-

Type: Lydella doryphora Riley, First Report, Insects of 

 Missouri, p. 111. 



The type species has been repeatedly reared from the larvae 

 of Leptinotarsa (Doryphoni) decemlineata in the northern and 

 eastern United States as far west as Missouri. 



Neadmontia, gen. nov. 



Erected for Adtnontia limata Coq. Whole body strongly bristly. The 

 true frontal bristles are numerous, strong and stop at base of antennae; 

 a row of closely placed weak bristles runs diagonally down the parafacials 

 below end of frontal row, but is not a true continuation of the latter. Facilia 

 not ciliate. Arista very delicately pubescent. Third antenna! joint a
