nised expert oil the Dra<5onflies of this region. Recently a small 

 collection of Dragonflies from the Himalayas was sent to him 

 for determination. These were collected in June, 1918. In the 

 consignment was a single larva, at first sight very much like a 

 Gomphine laiva, which was taken from a rapidly running stream, 

 between Ghum and vSonada, (S. Kemp coll.) at the very high eleva- 

 tion of 7000 feet. The larva, to judge from the length of its wing- 

 sheaths, which reach slightly beyond the end of the second abdominal 

 segment, is in the penultimate instar. The wing-sheaths, of which. 

 a pair were dissected off, show the imaginal venational pattern 

 fairly plainly, though the tracheation, of course, had collapsed 

 through long immersion in alcohol. The result of 'Sir. Laidlaw's 

 study of this interesting larva was to lead him to believe that it 

 belonged to the genus F.fiophlcbia. This result was so startling 

 that he had the larva and its wing-sheaths photographed at the 

 British Museum, where he also consulted Mr. Herbert Campion as 

 to its probable identity As will be seen from the photographs, 

 which are reproduced in plate XIII, it was scarceh- possible to 

 come to a definite conclusion on the matter, though Mr. I.aidlaw 

 felt very strongly that his original determinatioir would pro\"e 

 correct. 



On June ist, 1920, I arrived in London from Sydney to attend 

 the Imperial Conference of Economic Entomologists. Shorth" 

 after, I met Mr Laidlaw and ^Ir. Campion at the British Museum, 

 where the photographs of the larva were submitted to me for my 

 opinion. I must confess that from the photographs alone, I could 

 see little evidence in support of Mr. Laidlaw's opinion. The general 

 appearance of the larva is distinctly that of a Gomphine or Petali- 

 ine, while the photographs of the wing-renation did not seem to 

 me sufficiently definite to go upon one way or another. As the 

 antennae were five jointed, the labial mask Gomphine like and the 

 tarsi of normal form and not formed for burrowing, I was inclined 

 to see in this new form the missing larval type of one of the 

 Chlorogomphinae, and suggested the genus Orogomphits. 



The outcome of the discussions at the British Museum was 

 that Mr. Laidlaw urged me to come down to Devonshire and study 

 the specimen itself, and the slides which he had prepared from it. 

 In July I had to go to Bristol for a few days, and this gave me 

 the necessary opportunity of visiting Mr. Laidlaw for a week-end. 

 I spent the greater part of the time studying this problematical 

 larva, with the result that I came away fully convinced that it 

 l)elonged to a new species of the genus Epiophlebta. I urged Mr. 

 Laidlaw most stronglv to write a paper upon it at once ; but he 

 most generously and insistently urged me, on the other hand, to 

 undertake the work myself, and finally 1 consented to do so. He 

 also lent me his notes and description of the larva, for use in the 

 preparation of this paper. 



I desire here to thank Mr. Laidlaw for his generous help and to 

 state that full credit for the original determination of this larva as 

 belnnging to the genus Epiophlebta is due to him alone. I consider
