BIOLOGICAL NOTES ON ORIENTAL DEMIPTERA. 571 



Coletis etrida, Bois. 



Local. Taken ut Serkia, Chandgiuh Reserve, north of the Nerbudda, in 

 November. The oraitge patch at the apex of the forewing serves to distinguish 

 this from the following species. 



Coletia dana', Fabr. 



Fairly common. Burhanpur ; in large numbers. Also Singaji and Khand- 

 wa. September-December. The crimson patch at the apex of the forewing 

 of the male is a distinguishing feature. In the females this patch varies 

 greatly in colour and extent, sometimes it is quite orange and sometimes it is 

 obliterated by black markings. A conspicuous and very pretty insect. 



v.— HESPERIID.E. 



Parnara mathias, Fab. 

 The common brown skipper with white spots. Identified by comparison 

 with specimens in the Bombay Natural History Society collection. 



In addition I have taken one or two other species of Hespeind viz : — 



Parnara bevani, Moore. 



and 

 Coladenia tissa, Moore.

The fourth paper of this series deals with Erthesina fidlo 'Thun- 

 ber'»-), a buo- belonging to the family Cimicidse and the tribe Halyini. 

 It is distributed throughout India, Assam, Burma, Ceylon, the Anda- 

 man Islands, Java, Japan, Formosa, China and Hainan Island. 

 Althouo-h so common and well distributed, there has apparently been 

 nothing recorded of its metamorphoses, and the only note connected 

 with it is by Distant (1879, P. E. S., London, p. Ivii), who states that 

 it is ground up into a kind of paste and eaten by the Nagas in Assam. 



The following brief notes are taken from Chinese individuals, but 

 will apply as well to Indian examples. 



Erthesina fidlo is very common throughout the wet season in 

 Southern China, feeding upon the camphor tree [Stillinyia sehifera 

 Juss. N. 0. Euphorbiaceas), Melia azedarach and several other trees,
