XIV. NOTES ON THE TRICHOPTERA 



IN THE COLLECTION OF THE 



INDIAN MUSEUM. 



By C. Betten. 



This collection includes thirty species of Trichoptera of which 

 eleven are described below as new. Among these thirty species 

 there were some which are listed in this paper, the specimens of 

 which were not in condition to admit of specific descr'ption. There 

 were in addition a couple of species of Limnophilidse and a 

 Rhyacophila unfortunately so much damaged that they cannot be 

 dealt with at all prope \y. In the case of most of the already 

 described species referred to, notes and drawings are here added in 

 the hope of improving our knowledge of these forms. The nomen- 

 clature of the wing veins adopted is not that commonly used in 

 this order. I have therefore labelled veins only in those cases in 

 which it was necessar}* to make the references in the text intelli- 

 gible. In studying this collection it has been very convenient to 

 have for reference Ulmer's list of Indian TrichopLera.^

Numerous specimens of both sexes from Sikkim, Kulu (W. 

 Himalayas) and Kurseong, Darjiling district (alt. 5,000 ft.). At 

 the last place I found the species common in the last week in 

 May, in 1906. 



Unfortunately Dr. Betten's MS. has been damaged in transit, 

 and the page containing his notes on this species is missing. The
