On Diptera from Vera Cruz. 19 
C. nicomache appears to be confined to North-east Conti- 
nental India, and the species here described is its near 
Burmese congener. 
Pomponia cuneata, sp. n. 
Head black, some marginal testaceous streaks to front and 
the same at base; eyes brownish ochraceous; pronotum 
ochraceous, with two central longitudinal fascie and the 
incisures black ; two castaneous spots on outer basal margin ; 
mesonotum ochraceous, with a central fascia, four obconical 
spots—the outermost largest—and a spot in front of each 
anterior angle of the basal cruciform elevation black ;, abdo- 
men above castaneous, the three basal segments posteriorly 
narrowly ochraceous at the lateral margins. Sternum and 
opercula pale ochraceous; face, legs, and abdomen beneath 
brownish ochraceous. 
Tegmina and wings pale hyaline, the venation either 
ochraceous or castaneous, the tegmina with the transverse 
veins at the bases of the second and third apical areas darkly 
infuscated, 
The opercula are somewhat acutely triangular, their 
narrowed apex reaching the second abdominal segment; the 
rostrum just passes the apex of the intermediate coxe. 
Long. excl. tegm. 25 millim.; exp. tegm. 66 millim. 
This species may be placed near P. seitula, Dist. 
Calcagninus marginatus, sp. 1. 
Body and legs ochraceous ; apex of the abdomen black. 
Tegmina pale ochraceous hyaline, the outer margin some- 
what broadly infuscated. Wings paler hyaline, their apical 
margins narrowly and obscurely infuscated. 
Opercula short, subquadrangular ; rostrum about reaching 
the base of the posterior coxe. 
Long. excl. tegm. 15 millim.; exp. tegm. 38 millim.
