EMBIA MAJOE FEOM THE HIMALAYAS. 169 



In July 1909 I bad the good fortune to meet with two large male Ernbiids belonging 

 to the species herein described for the first time. They occurred among herbage 

 growing along the sides of a rivulet, at an altitude of 4600 feet, in the Naini Tal 

 district, in the Himalayan foot-hills of Kumaon. Since that time, I have visited various 

 parts of the same district at different times of the year, and have been successful in also 

 procuring the female, the eggs, and the silken nests of the insect in comparative 

 abundance. I was thus enabled to make a more extended series of observations on the 

 habits and post-embryonic development of a single species of Embiidae, than has fallen 

 to the fortune of previous students of the group. 



2. Description of the Male. 



Deep brown-black, clothed with dark brown or almost black hairs. The antennae 

 20-29-jointed, a little shorter than the combined length of the head and thorax. The 

 head, thorax, and abdomen mutually related in length in the proportion of 3 : 5 : 8. 

 The first joint of the hind tarsi with two arolia. The 10th tergum completely divided 

 into a pair of plates, the right being considerably larger than the left. The left plate 

 produced into a stout curved process ; the process of the right plate only represented by 

 a minute papilla. The process of the 9th sternum large, curved at the apex only. 

 Basal joint of the left cercus much enlarged, conical ; its proximal surface armed with 

 numerous minute scattered denticles. Distal joint of both cerci similar to one another. 

 Upper wing 8 - 5-ll-25 mm. long, 275-3 - 5 mm. broad ; lower wing 8-10 - 5 mm. long, 

 2"5-3"5 mm. broad. 



Length 1275-18 mm. 



The Head. — The head is longer than broad with the posterior margin rounded ; it 

 attains its greatest diameter between the eyes. It is uniformly clothed with longish, 

 almost black hairs. The eyes are only partially visible from above, reniform in shape, 

 and have their concave side closely embracing the basal joint of the antenna. 



The labrum is much broader than long, with its anterior angles prominently rounded 

 (PI. 38. fig. 8). It presents no special features. The epipharynx is represented by a 

 longitudinal row of setse on either side of the pharyngeal surface of the labrum. These 

 setse are most probably sensory in function. The clypeus is larger than the labrum and 

 is divided into a membranous ante-clypeus {a.cl. in fig. 8), and a wider and fully chitinised 

 post-clypeus (p.cl.), which articulates with the epicranium just in front of the bases of 

 the antennae. 



The antennce vary in length from 6-7'5 mm. and are larger than the thorax, but a 

 little shorter than the combined length of the head and thorax. The number of joints 

 varies between 20 and 29, the most usual number being from 23-27. More than half 

 the individuals examined had one or both of their antennae imperfect. The basal joint 

 (PL 38. fig. 2) is the widest, and the third joint the largest ; the succeeding joints differ 

 very little individually among themselves. The combined length of the 4th, 5th, and 

 6th joints exceeds that of the first two joints. 



The mandibles (PL 38. fig. 5) are slender, considerably longer than broad, and much
