Subfamily I. GERYDIN^. 



Egg. " Less than one-third high as wide, delicately and some- 

 what obsolescently reticulate, so'.netimes carinate, flat above and 

 below.'' (Dolierty.) 



Larva and Pupa. So far as I know no description of these has yet 

 been published. 



Imago. Wings elongate, delicate and generally of a dull, sober 

 coloration. Fore wing with eleven veins, vein 9 absent. Hind 

 wing: all the veins present. Termen in both wings sometimes 

 uneven and dentate. Antennae moderate, about half length of 

 fore wing ; club gradual ; palpi rather long, with the third joint 

 markedly so and slender. Body slender, abdomen proportionately 

 rather long. Legs remarkablv abnormal ; the first joint of the 

 tarsi elongate, in one genus flattened also ; another genus has the 

 tibiae incrassate. The genitalia of the d 1 in the Grerydince, 

 according to Doherty, are peculiar, distinguished by the " long thin 

 plate-like prehensores resembling the valves of the Papiliouidae."

The habits of the members of this subfamily are alike. The 

 females (at any rate of Gerydus and Allotinus, which I have closely 

 observed in life) flutter about among low bushes and the under- 

 growth at the edges of the forest. The males, on the contrary, 

 sit erect on the upperside of the leaves at the extremity of some 

 branch of a tree at no great height above the ground, and from 

 these points of vantage make short, sharp, circling flights, 

 returning to the same or neighbouring leaf and invariably sitting 

 with their heads turned towards the open and not towards the 

 tree. A remarkable habit in one member of this subfamily, viz. 

 Allotinus horsfieldi *, has been communicated to me by Colonel H.
