244 Records of the Indian Museum. [Vol. VI, 



shining light brown stripes, tapering in width behind, the ist 

 central and attaining the anterior margin, the stripe on each side 

 reaching the shoulders and terminating above the mesopleurae. 

 Behind the middle transverse suture the dorsum widens out until 

 the posterior corners form sharp angles. This posterior portion of 

 the thoracic dorsum bears a wide brown stripe on each side, 

 divided by a small longitudinal suture ; the stripes beginning 

 behind the ends of the two dorsal side stripes which are in front, 

 and extendnig backwards to the small scutellum which is all 

 yellow. Metanotum of moderate size, all yellow. Sides of thorax 

 yellow, with a shining, very dark brown triangle just below the 

 root of the wing, and a downward brown streak behind and rather 

 above it. Under side of thorax dark brown ; a prominent, small, 

 circular, pale yellow callosity in front of the hind coxae. 



Abdomen concolorous with irregularly scattered hairs. Bases 

 of all the segments brown, this colour apparently varying in 

 breadth ; 2nd segment much contracted ; 3rd and 4th suddenly 

 widened; the rest tapering to a point. Ovipositor short, reddish 

 brown, shining. Belly yellowish, with traces of some transverse 

 bands, corresponding to those on the upper side. 



Legs yellowish tawn}^ ; coxae brownish yellow, tarsi blackish, 

 bare of long hairs or spines, with microscopically yellow pubescence 

 on the femora, which is much mixed with black pubescence on the 

 tibiae. 



Wings yellowish, unmarked, stigma yellowish, indistinct, 

 small ; veins and halteres brown. 



Described from one 5 from Sylhet in the Indian Museum 

 collection in perfect condition. 



Pselliophora terminalis, mihi, sp. nov. 



9 . Tonkin. Long. 30 mm. -\- ovipositor 3-4 mm. 



Head bright chrome-yellow, vertex dark brown, the colour 

 extending forward in the centre almost to the root of the 

 antennae. Proboscis a little brown on upper side, labella dark 

 brown, nearly black ; palpi brownish yellow, black towards tips. 

 Antennae bright yellow, scape normally shaped, ist joint large, 

 wider at tip, 2nd joint small, subannular : ist flagellar joint i|- 

 times the length of the next joint, deeply cut away below in the 

 middle, as are the rest of the flagellar joints, but in the ist joint 

 the basal and apical halves are about equally deep, whereas in the 

 remaining joints (except the apical one) the basal part is much 

 deeper than the apical : apical joint elongate, narrow, constricted 

 in middle below. 



Thorax bright chrome-yellow. Dorsum with three rather 

 dark brown stripes, the median one of which reaches the anterior 

 border, being divided for the greater part of its length : the outer 

 stripes foreshortened, barely interrupted at suture, behind which 

 they take the form of a circular and an oval spot. On the rest 

 of the thorax there are slight brownish traces here and there.
