N.B. — This species differs from all other Eastern ones by the 

 brilliant blue colour, its yellowish shoulder spots, and rather 

 smaller size. It is near, but quite distinct from, the European 

 O. antJirax. 



Limnophora kempi, mihi, sp. nov. 



o* Assam. Long. 3 mm. 



Head. — Eye margins narrowly pale yellowish grey, the width 

 not uniform but continued with extreme narrowness to between 

 the points of greatest contiguity of the eyes. The whole of the 

 remainder of the front part of the head very pale grey-dusted with 

 a slight bluish tinge. Two or three short bristles on upper part of 

 eye margin, alongside of the dull-reddish brown frontal triangle. 

 Vertical triangle dark grey, a few short bristly hairs, the three 

 ocelli very small, brilliantly shining ruby-red, placed on extreme 

 angles of the triangle. A longer pair of bristles just behind the 

 vertex, convergent, placed one behind each corner of the ocellar 

 triangle. Antennae black, arista microscopically pubescent only. 

 A pair of strong oral vibrissae. Back and underside of head 

 dark grey with short stiff black hairs. Proboscis black ; palpi 

 black, slender, rather long, slightly enlarged at tips. 



Thorax — Pale cinereous grey (centre part damaged by pin), 

 with at least four rows of bristles of various sizes. There are 

 three stronger ones in the humeral region, four more or less in a 

 row from below the humerus to the wing root, three or four above 

 and in front of the wing. Scutellum concolorous, with three pairs 

 of bristles, one post basal, near the sides, a smaller pair near the 

 middle of the dorsum, and a long apical pair. 



Abdomen . — Dark grey, the dorsum of the segments appearing 

 more or less darker according to the angle at which they are 

 viewed. Surface of abdomen covered with soft black hairs and a 

 row of stronger bristly hairs near posterior border of each

Legs. - Dark brownish black, shortly pubescent; femora and 

 tibiae with numerous spines and bristles : all tibiae with a circlet 

 of spines near tip.

Described from one cf from Sadiya, 25-xi-ii. 



Lispa ? pallitarsis, Stein. 



Two specimens from Dibrugarh, 17 — 19-xi-ii, agree so closely 

 with the description of this species that it seems likely they are 

 identical, although disagreeing in one or two points. They agree 

 in the shining black unmarked thorax, in the absence of strong 

 bristles in this part except towards the sides, in the black face and 

 antennae, in the oblong or sub-cylindrical abdomen with a 

 narrow whitish mark on the anterior margin towards each side of 

 the 2nd to the 4th segments. This character alone is quite
