* Pseudosira indra, sp. n. (PI. YII. fig. 32 ; PI. YIII. figs. 

 37-40.) 



Unguicidus superior tridenticidatus ; denticidi jm-pai^vi, ita 

 collocati ut v,7ms post alterum inserttos sit. Unguicidus inferior 

 lanceolatas, inermis. 2Iucrones breves, falciformes. Tihice pilis 

 davatis sinr/uUs instructce. Artictdo quarto antennartmi longissimo, 

 primum et secitndum longitudine cequante. Long. 1*5 mm. 



Head. — A little longer than the mesothorax ; clothed with 

 scales, among which on the dorsal aspect are long stout setse, 

 ciliated along one side at the apex. The eyes eight in number on 

 each side ; no post-antennal organs (fig. 37). 



Anteniue. — As long as, or, in some examples, a little longer than 

 the furcula. The joints related respectively in length as 

 4 : 7 : 7 or 8 : 1 1 . The first two joints clothed with scales, the 

 third and fourth joints clothed with small hairs. 



Trunk.— Clothed with scales of somewhat variable shape, but 

 for the most part oval or linear-oval. The scales are finely and 

 faintly striated, with a relatively long, and very slender pedicel 

 (fig. 40). Sefce (fig. 39), similar to those found on the head, 

 form a kind of "frill" or " collar " along the anterior edge of 

 the mesothorax ; a few are also scattered over the general surface 

 of the body, and there is a terminal tuft at the extremity of 

 the abdomen. The trunk segments mutually related in length as 

 7 : 5 : 4 : 4 : 6 : 15 : 3 : 1. 



Lerjs. — All the feet similar ; the distal extremity of each tibia 

 provided with a single tenent hair. The superior daivs slender 

 and acuminate, armed with three small teeth along their inner 

 margin. The inferior daws linear and acuminate, acicular, 

 unarmed (fig. 38). 



Hamula. — The corpus with a median stout anterior seta placed 

 in front of the rami. Each ramus quadridentate. 



Furcula. — Slender, reaching to the ventral tube. The vianu- 

 hrium somewhat shorter than the dentes ; scaled. The denies 

 clothed ventrally with scales. The mucrones hook-shaped 

 (fig. 32). 



Coloration. — Greyish white when denuded of the scales ; when 

 the greater number of the scales are pr'esent the ground colour 

 appears markedly brown. The antennte tinged with violet, a slight 

 violet suffusion on the mesothorax, and some small lateral patches 

 of the same colour on either side of the abdomen. The furcula 

 white. The eyes on a black patch on each side of the head. 



Length varies in different examples from 1-25-2 mm. 



Five specimens on the surface of the pool in the " com- 

 pound "' of the Indian Museum, Calcutta {A. D. Imms, December 

 31st, 1909). The specimens were apparently immature.
