176 Records of Ihe Indian Museum. [Voi,, XVI, 



Prothorax. — Dorsal surface black, with a narrow yellow collar 

 anteriorly ; ventral and lateral surfaces yellow. 



Thorax. — Dorsally black, with narrow green-blue antehumeral 

 bands. Sides green-blue with a small black mark at the upper end 

 of the second lateral suture. 



Abdomen. — Segments 1-2 pale blue- green, but 2 changing to 

 orange at its apex. On the dorsum of i is a square bronze-black 

 mark ; on the dorsum of 2 is a bronze-black mark shaped in most 

 of the specimens like a wine-glass with a stout short stem, the 

 "foot" of the glass resting on the apex of the segment, the 

 " brim " on the base. In two of the males however the '' bowl " 

 of the glass is larger and the '' stem " practically absent 



Segments 3-6 are bright orange, each with a fine black ter- 

 minal ring ; 7-10 are jet-black. Apical tubercle of 10 well marked, 

 ending in a pair of small pointed processes directed backwards, 

 and a little downwards. 



Anal appendages yellowish-brown; the upper pair very short, 

 directed downwards and each ending in two minute digitations 

 of which the inner is the larger. Lower pair longer, tipped 

 with black ai their apices, stout at the base, each rapidly tapering 

 to a fine point which is incurved, so that together they resemble 

 the horns of a bullock. 



The appendages bear a very close similarity to those of 

 L. rufostigma, Selys. They differ chiefly in that in the latter 

 species the upper pair are relatively a little larger, the digitations 

 more equal and a little more divaricate, whilst the lower pair 

 are not so sharply incurved. 



Legs yellowish-white, distal ends of femora marked with 

 black; spines and tarsal claws black. 



Female. 



Head much as in the male, but ground colour duller; the 

 post-ocular spots obsolete, at least in the adult; the occiput, over 

 which in the male the black of the vertex extends, is in the female 

 yellowish- brown. 



Prothorax as in the male. 



Thorax, ground colour yellowish-brown ; dorsum with a broad 

 bronze-black, medium band, succeeded by pale whitish-yellow 

 antehumeral bands. These are not enclosed by lateral black 

 bands, as in the male, but lie in contact with an ill-defined 

 red-brown humeral area which fades gradually into the paler 

 brownish-yellow lateral colouring. The humeral suture itself is 

 marked with a very fine black line. 



Abdomen orange-brown; each segment with a broad, dorsal 

 band of bronze-black running longitudinally. 



Legs as in the male. 



It is perhaps more correct to say that the post-ocular spots 

 in the female are not enclosed behind by black colour than to 

 speak of them as obsolete.
