are 5 pairs of gill-tufts^ one in front of each lateral process, 

 excepting those of the head-segment. Behind the last sucker 

 there are 4 gills much larger than the others. These probably 

 represent another type of tracheal gills. This is the most common 

 larva, over 260 specimens out of a total of over 275 larvae 

 belonging to it. 



Among specimens belonging to this species are some forms 

 (Ivarva A') which are very much broader in proportion to their 

 length than the typical individuals. I have not been able to find 

 any other characters, in which they differ from the type and am 

 not in a position to say whether they really represent the same 

 species. The outline figure (fig. 11) will give a good idea of ths 

 appearance. The larvae appear to be very much like those of the 

 genus Blepharocera as figured by Kellogg and others and it is to be 

 hoped that they represent the larvae of Blepharocera indica, 

 Brun., which has been described from the Western Himalayas {Rec. 

 Ind. Mus. IV, p. 3e6 (rgii) and Fauna Brit. India, Nematocera, 



P 156). 



Types preserved in the Indian Museum. 



Larva B. 

 (Plate xvii, figs. 12-13.) 



Length 6-7 mm. The markings in the dorsum of the head 

 and thoracic segment consist of a single dark patch with an ellip- 

 soidal groove in the middle. In some there is a tendency to have 

 this patch divided into three areas like those of the larva A. 

 Behind there are some darkish markings. The abdominal seg- 

 ments have each a single dark transverse bar. There is a row 

 of 6 spines on each side of the body, one spine being placed a 

 little above the base of anterior lateral process; each of the 

 abdominal segments except the last has 4 spines, a pair in front 

 and a pair behind the transverse dark bar. The head and thoracic 

 segment as well as the last segment have two spines only. 



Lateral processes not very conspicuous, double; the anterior 

 member o. each pair longer and bearing at lip a long spiny hair; 

 lateral processes pale fuscous in colour ; tracheal tufts in groups 

 of 4 each, rather short, 3 of them directed anteriorly and i pos- 

 teriorly; antennae rather short, three-jointed. 



Described from 15 specimens from among those collected by 

 Mr. Bion at Nagaberan in Kashmir. 



Types preserved in the Indian Museum. 



Larva C. 



(Plate xvii, figs. 14-15.) 



Long and broad; length 8-6 mm. The markings on the head 

 and thoracic segment consist of a central rhomboidal area in two 

 sides of which are two nearly triangular patches ; the central
