46 Captain T. Hutton's Notes on Indian Lepidoptera. 



positively known how such escape is made. Look to Saturnia 

 for instance, or at least to some of the genus, which are described 

 as having " no mouth and as taking no nourishment in the imago 

 slate f how does such a moth effect its escape? It cannot be by 

 ejecting a fluid from the mouth to dissolve the threads, because 

 the mouth is wanting ; it must therefore be done by some such 

 instrument as that already pointed out, or by a fluid from the 

 anus. In regard to the common Tusseh moth of India, which is 

 said to possess no mouth, the escape from the cocoon, which is 

 very hard indeed, is effected by a liquid and not by cutting ; this 

 I have frequently watched ; the liquid must surely be from the 

 anus, since the mouth is wanting ; the new mulberry moth which 

 you have kindly noticed (Bombyx Huttoni, Westw. Cab. Or. Ent. 

 pi. 13, f. 4,) likewise effects its escape, as does B. mori, by moisture, 

 but whether from mouth or anus is, I suspect, not precisely deter- 

 mined. 



In the 112th number of the Annals of Natural History I see 

 Captain Boys remarks that he had never observed any Lucani 

 in the plains of India, although very common in the Himalayas : 

 Lucrmus Girafa of Olivier has nevertheless been captured at 

 Saugor in central India by Mr, Benson, and I took it abun- 

 dantly last year at the foot of the hills in the Deyrah Dhoon ; 

 that valley however, at the place where the insect was taken, has 

 an elevation of about .3500 feet above the sea. I likewise last 

 year obtained a very curious and interesting beetle at Mussooree, 

 elevation about 0500 feet ; it was cut out of the trunk of an oak tree 

 vvhich was being broken up for fire wood ; it is allied to Scarabceus 

 longimanus, and belongs, I suspect, to the genus Eucheinis. I shall 

 send it home shortly, and beg of you to present it to the Ento- 

 mological Society of London, with my best respects. Mr. Benson 

 obtained the thorax of another specimen from a similar situation, 

 and a lad at this place possesses a perfect inale likewise, but will 

 not part with it. 1845 was the first year in which any of us sus- 

 pected the existence of such an insect up here, and yet we have in 

 some instances collected for the last ten years. By the bye, I 

 observed in a former number of the Annals and Mag. Nat. His- 

 tory, that you had read before the Entomological Society an 

 extract of a letter from Colonel Hearsey, in vvhich he states that 

 he had seen Papilio Pammon and P. Po/ijles in coitu ; this appears 

 to induce, or rather to confirm, an opinion which had previously 

 been entertained, namely, that the insects were identical, being 

 the two sexes of the same species. This opinion I am convinced 

 is wrong, and the insects totally distinct as species, and my reasons 

 are these; viz. 1st, I possess specimens of males and females of
