resemblance in colour, size, and amount of infuscation of the wing 

 tip between this species and the Tipulid Pselliophora compedita, W. 

 seems more than coincidental. Possibly one is distasteful to the 

 birds and the mimicry of the other is protective. 



Eudmeta marginata, F. 

 Five cf cf from Darjiling, 1000 — 3000 ft., June, 1912. 



Ampsalis longispinus, mihi, sp. nov. (PI. xiv, figs. 2, 4, 16). 

 cf 2 Darjiling, 1000 — 3000 ft. Long. 10 — 13 mm. 



Head twice as broad as long. Eyes in cf contiguous for the 

 greater part of the distance from vertex to antennae ; frons shining 

 black in cf , in 9 from one-fourth to one-fifth the width of the 

 head, less shining, bare. Ocelli on a distinct prominence, yellow- 

 ish. Antennae black, ist and 2nd joints subequal, cylindrical, 

 barely broader at the narrowly brown tips, minutely spinose; 3rd 

 joint cylindrical, almost filiform, pointed, with 8 annulations, 

 Occiput black, minutely pubescent. 



Thorax dull black, with microscopic pubescence which in 

 perfect examples is probably blackish or dark grey. Traces of a 

 little brownish-yellow colour behind the wings, and the hind 

 corners of the dorsum distinctly so coloured. Scutellum conspi-

 some soft (? pale) hairs, and two apical very long and powerful 

 reddish-brown spines, half as long as the abdomen, diverging and 

 directed slightly upwards. 



Abdomen brownish-yellow ; ist and 2nd segments mainly black, 

 hind border of latter brownish-yellow, 3rd and 4th each with a 

 rounded or subquadrate blackish spot of considerable size towards 

 each side of the dorsum, but clear of the margins. In the ?

 segments. The 5th and 6th segments in both sexes mainly black, 

 but sides and hind margins brownish-yellow. Belly with ist, 2nd, 

 4th and 5th segments mainly black, remainder brownish-yellow. 

 In the $ the black colour is a little more extended ; in both cf

 drical tube, with a pair of rather long brownish-yellow hairy 

 filamentous appendages.
