little concave on upper (front) edge, the upper (front) terminal angle more 

 or less produced into a short blunt tooth. Abdomen with discal and mar- 

 ginal macrochaetse. Apical cell closed almost at wing-tip. 

 Reproductive habit unknown, but probably larviposition. 



Type: Admontia liniata Coq., Proc. U. S. Nat. Mus., 

 vol. xxxv, p. 105. 



Coquillett's interpretation of the genus Admontia is a 

 complex. His Ad. dcmylus is evidently one of the compsilurine 

 flies, as indicat"d by the statement in description that the 

 abdomen of female is thickly beset with short spines on under- 

 side of third and fourth segments. It parasitizes Cophyrus 

 larvae. It is possible that his Ad. retinue, described from males 

 only, is an Actia. His Ad. polita probably belongs to the 

 present genus Neadmontia. His Ad. pergandei and degeer- 

 ioides seem to fit the genus Admontia. His Ad. setigera 

 (San Mateo County, California, specimen) is a different genus 

 from all of these. It lacks discal abdominal bristles, and bears 

 on parafacials a true continuation of frontal bristles in a row 

 extending to lower border of eye, all the frontal and parafacial 

 bristles being of equal strength at root. This California 

 specimen is a female and shows no ventral carina. 



Specimens determined by J. A. Hyslop as Admontia per- 

 g-audeiCoq.were reared by him from larva? of Tipula infii scuta, 

 Jackson, Tennessee. Nineteen flies issued from October 7 to 14, 

 1908. A reared female was found by Hyslop to contain 103 

 elongate eggs. The genus is recorded as parasitic in larvae of 

 Tipulidse in Europe. The female probably deposits maggots 

 on the surface of the soil, and these penetrate later in search 

 of the tipulid larvae. 



TD389, collected by D. H. demons, August 21, 1908, 

 North Saugus, Massachusetts, and determined by W. R. 

 Thompson as Admontia degeerioides Coq., showed a slender 

 uterus containing about 55 eggs and maggots similar to those 

 of the compsilurine flies in general appearance. Female 

 without piercer, with discal abdominal bristles, ciliate facialia, 

 long, slender third antennal joint, and apical cell ending near 

 wing-tip. 



Oxexorista, gen. nov. 



Erected for Exorista eudrya Towns. This has the general external 

 characters of Sisyropa. But until the female of Tachina thennophila 

 Wied. of Java (type of Sisyropa)\s dissected, we shall not be able to say 

 what the genus Sisyropa is. Eumasicera coccidella Towns, has apparently 

 the same general external characters as T. therwophi/a\\<\., and the female 

 fly is almost indistinguishable externally from the female of Sisyropa 

 hemerocampa; Towns. Yet the last (TD387, Gip. Moth Lab. 1976) deposits
