APPENDIX.

 (Plate XI.) 



Since I handed over a collection of Gomphines to Mr. Laidlaw 

 in 1920 I have come into the possession of a further lot collected 

 partly by myself and partly by friends who have kindly placed 

 them at my disposal. 



Some of these have already been described, viz. Stylogomphus 

 inglisi, nearly related to Heliogomphus, Onychogomphus sp., and 

 females of two distinct species of Heterogomphus, which will 

 appear shortly in the Memoirs of the Department of Agriculture 

 in India, Entomological Series. The remainder, some no species 

 are now before me and provide new material and add new light 

 to what has already been given above by Mr. Laidlaw. Dr. 

 Annandale has kindly given me this opportunity of adding to the 

 most important paper which has appeared on the Indian Gom- 

 phinae since Williamson's paper was published in 1907. 



Some of the present genera will have to be further split up, 

 I refer especially to the genus Onychogomphus, the larvae of two 

 species of which, 0. biforceps and 0. linealus, are contrasted below. 

 The body of the former is broad and greatly depressed and its 

 antennae broad, flat, triangular plates, the body of the latter is 

 narrow and cylindrical, whilst its antennae conform to such as 

 prevail amongst the majority of known Gomphine larvae (see 

 text-fig., p. 426). With such wide variations in structure, it is 

 impossible to believe that the two insects fall into the same 

 genus. 



With a long and wide experience of these insects in their 

 natural habitat, I am able to say that few species occur commonly ; 

 a few such as Cyclogomphus and Anormogomphus are locally 

 common, only two are widely spread, the remainder are come 

 upon at odd intervals and in unexpected places and then only as 

 solitary individuals. 



With the exception of 0. lineatus and Ictinus rapax they are 

 single brooded, a few species emerge in swarms, generally after 

 heavy rain and their appearance is of remarkably short duration, 

 two to three weeks being the extent of their life on the wing. 



The types of new species described below will eventually be 

 deposited in the national collection in the British Museum, at 

 present they remain in my own collection. I hope to place para- 

 types in the Indian Museum, at least as far as the Nilgiri species 

 are concerned.
