seen with a little difficulty. As regards the colour, the Indian 
specimens are darker than the Brit. Mus, specimen in the cephalic 
part, the falces and the abdomen. 
Myrmarachne laetus var. flavus, n. var. (@) 
A specimen, collected by Mr. Paiva at Katihar, resembles 
M. laetus very closely, but there are the following differences. The 
fang is devoid of a tooth in the middle which is present in 
M.laetus. As regards the colour, this variety is distinctly pale 
yellow. The falces are pale yellow, with a blackish patch on the 
dorsal surface. The cephalic part is black dorsally, but laterally 
it is light brown like the thoracic part. The abdomen is yellowish 
anteriorly but black in the posterior two-thirds. 
Myrmarachne providens (Peckham). 
Peckham, Ant-like Spiders, 1892. 
One specimen was collected by me at Navankot (Lahore). 
This species is very similar to M. Jaetus but differs in the smaller 
size of the falces, which are more strongly rounded towards their 
exterior margin. 
Myrmarachne himalayensis, sp. nov. 
(Plate xxxti, figs. 5a-c.) 
Two @ specimens of this species were collected by Mr. 
Gravely at Ghumti in the Darjiling district, at a height of about 
4000 ft. Unfortunately the abdomen is separated from the cephalo- 
thorax in both specimens; otherwise, the specimens are quite 
whole and all structures can be made out easily.

Total length 7 mm. 
Cephalothorax: length 3:'2 mm.; width 2 mm.; cephalic

Falces 1°6 mm. 
Legs 1432. 
The cephalothorax is moderately high, the cephalic part being 
a little higher than the thoracic. ‘The constriction between the 
cephalic and thoracic part is not so deep 
as in M. tristis or M. laetus, and it is 5 
only just indicated. The cephalic part 
is a little convex dorsally, almost flat, e182 
but rounded on the sides. The tho- 
racic part begins a little lower than the 
cephalic and slopes gradually to its pos- Text-ric. 2.—Cephalo-
