There is likely to be difficulty with this genus Halpe beoause of the 

 diverse forms contained in it. In that case, recourse must be had to 

 the venation and the other key. Of course any species of the genus 

 can at once be distinguished from the genus Coladenia by the fact that 

 (only honor ei can be confused with that genus in this key) all mem- 

 bers of Coladenia rest with the wings horizontal while Halpe keeps 

 them closed over the back ; also from all the orange marked (again it 

 it is only honorei that comes into question) butterflies : Telicota, Pa- 

 dmona, Ampittia, by the fact that none of these ha\ e a yellow patch 

 on the upperside of the hind wing and none have black spots on the 

 underside (honorei has). Finally astigmata can be differentiated from 

 any Baoris by the pure-white, silvery spots on the rufous ground of 

 the underside of the hind wing and hyrtacus by the white patch in the 

 same place. 



No notice has been taken, in this las t key, of the horizontal and 

 erect positions of the wings because, after a butterfly has been 

 captured, the fact whether it rests with the wings open and spread -or 

 closed is not ascertainable. The same is the case with papered speci- 

 mens generally. Marginal figures have been added showing the 

 different shapes of wings, the style of marking of the under sides of 

 the hind wings and the size and arrangements of the diaphanous spots 

 on the fore wings upon which differences are based. 



The key to the 62 spficies, finally, will be as given below. All detail 

 has been avoided as full descriptions are given under the life-histories 

 oi the different insects which will form the bulk of the letter-press 

 dealing with the Hesperiidw. 



Genus 1. Celcenorrhinus. 



A. — Fore wing: upperside i with a row of indis- 

 tinct, ochreous spots just inside outer mar- 

 gin. Expanse : 50-56mm. . . . . . . ambareesa {!). 



(PI. N., figs. 85, 85a). 



B.-^Fore wing: upperside : no such spots. 



a. Hind wing: upperside : with medial, and 

 discal series of orange spots, sometimes 

 some of them obscure. Expanse : 



50mm. . . . . . . . . . . leucocera (S). 



b. Hind wing : upperside : no such orange » 

 spots . . . . . , . . . . area (3). 



Genus 2. Satarupa (Daimio). 



One species. Expanse 24mm.. . . . . . milliana (4). 



Genus 3. Tagiades. 



A. — Hind wing : upperside t whole outer half 



white (black spots). Expanse 40-45mm. . . litigiosa (6). 



B. — Hind wing: upperside i outer half at most 

 suffused with white in varying degree, the 

 white greyish or bluish, never quite pure. 

 Expanse : 50mm. . . . . . . . . obscurus (5).
