CLASSIFICATION OF THE ASCALAPIIIDJE. 267 



The wings vary much in tinting in different individuals, and cer- 

 tainly independently of species. At present I can separate only 

 three specific forms, as under: — 



1. H. javana, Burmeister. (Ascal. javanus, Burm. Handb. ii. p. 1001.) 

 Pedes nigri. Appendices maris breviores, cylindricae, forcipatae, ad 

 apicem vix incrassatae, nigrae, ad basin piceae, pilis spiniformibus 

 nigris vestitae. 



Hab. Malay archipelago. 



2. H. subjacens, Walker. (Ascal. subjacens, Walk. Cat. Brit. Mus. 

 Neurop. p. 431 ( $ ). — A. remotus, Walk. op. cit. p. 447 ( ? )• — Bubo 

 jayanus, Ramb. Nevrop. p. 355, nec Burm. ?) Major. Pedes rufe- 

 scentes. Appendices maris longiores, cylindricae, robustae, forcipatae, 

 rufescentes, pilis spiniformibus nigris vestitae. 



Hab. China ; Japan ; Formosa. 



Larger than javana and separable especially by its reddish legs 

 and the much longer and stronger appendices of the d . 



Bemota is placed in the HolopJithahni by "Walker; but the 

 type is a much damaged individual (absolutely specifically iden- 

 tical with that of subjacens), in which the eyes are mutilated 

 through one division having been removed ! 



Rambur gives no locality for his javanus. Judging from the 

 colour of the legs and appendices, I consider that his species is 

 probably subjacens. I have seen individuals of the genus Hybris 

 from various islands of the Malay archipelago that I consider to 

 be the true javana, and all have black legs and appendices. 



3. H. angulata, Westwood. (Ascal. (Ogcog.?) angulatus, Westwood, 

 Cab. Or. Ent. — Ascal. accusans, Walk. Cat. Brit. Mus. Neurop. 

 p. 431.) Magnitud. H. subjacentis. Alae latiores. Pedes piceo- 

 nigri. Appendices maris breves, haud forcipatae, intus concavae, rufae, 

 ad apicem spinis brevibus nigris dense instructae. 



Hab. Assam ; Silhet. 



A broader-winged insect with very differently formed appen- 

 dices. The colour of the dorsum of the abdomen is of a much 

 brighter red than in the allied species. 



4. H. (?) cervina, Hagen. (Ascal. cervinus, Hag. Verh. zool.-bot. 

 Gesell. in Wien, 1858, p. 481.) 



Hab. Ceylon. 



Unknown to me. It might be a Glyptobasis, only that Hagen 

 in describing the wings says, " margine anteriorum basali angu- 

 loso," which will scarcely apply to the appendiculate wings of 

 that genus.
