208 JOURNAL, BOMBAY NATURAL HISTORY SOCIETY, 1893. 



Bombay Presidency, is a place to which the military members, at 

 any rate of the Society, are at some time or other likely to gravitate, 

 and it is in the hope that these notes may be o£ interest to some 

 members (whether past, present, or future inhabitants of the place), 

 and that they may induce some of them to enter into further inves- 

 tigation of its entomology, that they are written. 



To the Anglo-Indian, Aden is too well known to require any 

 description of its leading characteristics, but few passengers (for 

 the matter of that, no great number of the residents) have any idea 

 of the affect on "the barren rocks of Aden" of a few heavy showers; 

 how almost immediately, as if by magic, vegetation springs up in 

 everv ravine and water-course, accompanied by a tolerably abundant 

 insect fauna. 



Eain may always be expected in January, February, and March, 

 and these months are par excellence the bug-hunter's season. 

 Heavy rain often falls in May, and this sometimes produces some good 

 butterflies towards the end of June ; and early in July, 1883, was such 

 a vear, and I obtained early in July Teracoliis miles and Thanaos 

 c?j«Z(e/cb,-— butterflies never again met with, — besides Ismene anchises 

 and other good insects. July is generally a good month too for moths. 

 Before enumerating the species obtained, it may be worth while 

 to mention the places found most productive. They were — in Aden 

 itself — Gold Mohur Valley and the valleys beyond as far as Round 

 Island, the Maala Plain, and the water-courses on the plateau 

 above the tanks : — outside the barrier — the so-called forest at Shaik 

 Othman, a cocoanut plantation at Huswah, generally round Al 

 Hautah (Lahej), and in the beds of the streams and at the edges of 

 cultivation at Haithalhim. 



My identifications have been taken in great measure from 

 Mr. Butler's account of my Aden collections, P.Z.S., 1884, p. 478. 

 I have added several species omitted by him iu the paper quoted. 

 The species obtained were as follows : — 



RHOPALOCERA. 



Family— Nymphalid^. 

 Subfamily — Banaince.
