defined, apex rather acutely rounded. Black; palpi tegulae, and 

 calaria testaceous ; tarsi and tibiae somewhat piceous ; densely clothed 

 with silvery pile, that of the thorax slightly yellowish ; pygidium with 

 silvery hair. Wings hyaline, iridescent, faintly yellowish; venation 

 testaceous. 



Male. — Length 9 mm. Clypeus rounded, without teeth; third 

 antennal joint shorter than the fourth; anterior coxae without spines; 

 pygidium truncate; last ventral plate deeply, broadly, arcuately 

 emarginate, lobes narrow rounded at apex. Otherwise very like the 

 female. 



Deesa, India. Described from a stylopized male and female, col- 

 lected June, 1898, by Lieut. Col. C. G. Nurse. 



Type.— Cat. No. 13763, "U.S.N.M. 



This may only be a stylopized aberration of Tachytes vicinus 

 Cameron, but at present it is impossible to prove such to be the case. 



Genus LARROPSIS Patton. 



Type. — Larrada tenuicomis Smith (original designation). 



Patton in describing 1 the genus Larropsis designated as the type 

 Larrada tenuicomis Smith. His description of the genus does not 

 apply to this species which led Kohl and Fox to treat it as an unknown 

 genus. The type-species is, however, a vv ell-known species and is 

 congeneric with Larrada disiincta Smith, the chosen type of Anci- 

 stromma Fox. Fox's genus being described a year later must rank 

 as a synonym of Patton's.

LARROPSIS FILICORNIS, new species. 



Female. — Length about 11 mm; antennae about 7 mm. Slender; 

 the shape of the head recalls that of the genus Lyroda. Anterior 

 margin of the clypeus rounded out, not distinctly dentate, but later- 

 ally there are faint indications of teeth; anterior part of the clypeus 

 is coarsely, irregularly punctured, the basal part is like the front; 

 eyes not nearly as strongly converging as usual, the distance between 

 them at the vertex a little greater than the length of antennal joints 

 two to four; front with an indistinct impressed line; depression 

 behind the lateral ocelli not strong; front and vertex rather closely 

 punctured. Antennae long and slender; the third joint a little shorter 

 than the fourth; apical joint equal in length with the preceding; 

 mesonotum, scutellum, and mesopleurae punctured similar to the 

 front, scutellum not impressed; dorsal aspect of propodeum rather 

 finely reticulato-granular, at some angles appearing finely obliquely 

 striated from the median furrow; a deep, longitudinal, foveolated
