Abdomen. — Blackish grey, with a brownish cinereous dust; a 

 few pale hairs at the sides ; genital organs in & large, robust, con- 

 spicuous, consisting of an upper and lower thick cup-shaped piece, 

 the former ending in two narrow blunted hairy points, the latter 

 ending in two short obtuse bare points, the two pieces together 

 enclosing a large ventral chamber in which are some smaller 

 intermediate processes of a yellow colour, the whole of the genita- 

 lia, otherwise, being black, with stiff black hairs on the outside. 

 In the 9 the organs are small, pale and inconspicuous.

 twenty small teeth on under side, each bearing a short spine. In 

 addition, a row of long stiff bristles. Anterior tibiae with at least 

 two long bristles on inner and two on outer side of each. Tarsi 

 black, with pale hair on under side, that on under side of hind 

 pair golden yellow, and there is a little such golden yellow hair at 

 the tips of the hind tibiae on the under side.

Described from a type & from the Botanical Gardens, Darjiling, 

 i2-viii-09 {Paiva], and at3'pe 9 from Kurseong, y-ix-og [Annandale], 

 both specimens in the Indian Museum. 



Hybos gagatinus, Big. 



The type of this species is in the Indian Museum collection, 

 and I therefore add a few details to Bigot's very short description. 

 The specimen is in fairly good condition except that the head is a 

 little crushed, and the antennae gone. A pre-alar bristle is 

 evident, two on the scutellum, nearly erect, and one or two on the 

 sides of the thorax. The under side of the thorax is dark bluish 

 grey. The legs are best described as moderately dark shining 

 brown. The anterior tibiae, the hind knees, broadly, and all the 

 tarsi, light brownish yellow. Legs pubescent, with two long 

 bristles on upper part of outer side of middle tibiae, and two 

 similar apical ones. The hind femora have a row of about 10 long 

 but not ver}^ strong spines on the under side. The wings are 

 quite clear, very iridescent, 6th vein somewhat faint; halteres 

 yellowish. 



Long. 4 (not 5) mm. Moreover the locality (Margherita) is in 

 Assam, not in India proper.
