Larvar from Kashmir. 



Along with the specimens of adulter' and 9 collected at Naga- 

 beran, Kashmir, were enclosed nearly 275 specimens of larvae of 

 all sizes. I first thought that they were all of one species, pre- 

 sumably PhilortiS hionis, sp. nov., with the adults of which they 

 were found to occur It was only when I examined the whole 

 collection carefully that I found them to belong to three distinct 

 species and a form which appears to be only a variety of one of 

 them. As none of the larvae agree with any Blepharocerid larvae 

 previously described and figured/ it has become impossible to 

 assign them to any species. I have, therefore, followed the onl}- 

 course open under the circumstances, m, to describe the larvae 

 and figure them without giving an}^ names. 



Larva A. 

 (Plate xvii, figs. 8-10.) 



The fully-grown larvae are from 7 to 8 mm. in length and 

 moderately broad. In the collection before me there are younger 

 specimens of various sizes from 3 mm. onwards. The general 

 appearance agrees with that of typical Blepharocerid larva, being 

 broadest at the head region with the successive segments slightly 

 narrower than those in front of them. The colour of the dorsal 

 surface varies from light cinnamon-brown to deep clove-brown. 

 The difference in shade does not appear to depend on the size of 

 the larva, but to some other cause, such as exposure to light. ^ 



The markings on the head consist of a central rectangular dark 

 area and two triangular ones on its sides, on the most anterior 

 region of the head segment. In the centre of the rectangular patch 

 is a nearly ellipsoidal area separated from the rest by a deep 

 groove which appears as a bright line when viewed by transmitted 

 light. The other markings on the head segnient are two transverse 

 bands, a faint one in the middle and a dark one in the posterior 

 part of the segment. On each of the other segments of the body 

 there is a transverse dark band in the middle. The ventral surface 

 of the body is white with the exception of the suckers, which appear 

 to the naked eye as dark circular rings. The lateral processes 

 are light brown in colour. 



Antennae: two-jointed, the 2nd joint having 4 or 5 small 

 papillose hairs with globular heads at the end. Proximal half 

 of each joint white, distal half black in colour. 



Lateral processes single, with a tuft of long fine hair-like pro- 

 cesses at the end of each. Tracheal gills in groups of 6.^ There 



1 With the possible (but very improbable j exception of the larva of P.yosemite, 

 described by Prof. Kellogg- in Psyche, Vol. X, p. 186, I could not get a copy of 

 this paper in any of the libraries in Calcutta. 



■^ Mr. Bion informs us that all the larvae were much paler in life than the>- 

 are in spirit. 



3 I have found the number of gills in a tuft vary from 5 to 7, but 6 is the 

 most common number.
