Xlii PROCEEDINGS OF THE 



ciated with the type of that genus, Penth. Mono, on account of its 

 transformations, the apterous state of the female, the want of palpi, 

 and peculiar veining of the wings in the male. The latter charac- 

 ter, as well as the almost obsolete, exarticulate antennae of the 

 female, likewise remove it from Psyche fusca, and the genus Fiimea 

 of Haworth. 



Mr. Westwood accordingly proposed for it the generic name of 

 Pachythella, considering it most nearly allied to the O'lketicus 

 MacLeay'il of Guilding. 



Mr. Westwood thought that^ notwithstanding some of the "Sack- 

 trcigers" are evidently related to the Tineidce and Hepiolidce, those 

 under consideration are most allied to some of the Arctiidce. 



Mr. Douglas remarked that Mr. Doubleday had at one time 

 thought it possible that this insect was the Psyche febretla of 

 Duponchel, but that though it evidently belongs to the same 

 group, he now considers it a distinct species.

Exhibitions, Memoirs, &rc. 



Mr. Ingpen exhibited a specimen of Papillo Alochuon, which 

 had been two years in the pupa state. 



Mr. G. F. Angas exhibited two large boxes containing insects 

 of various orders recently collected by himself in the interior of 

 South Africa. Amongst them were two new species of Papilio, 

 two or more new species of Acrcea, two new genera of Nympha- 

 I'ldce, a magnificent new Saturnia of the subgenus Actias, and 

 many other exceedingly rare or entirely new insects. 



Capt. Parry exhibited a box of Coleoptera from Ceylon, con- 

 taining many rare species. 



Mr. W. W. Saunders exhibited a male and female of Cystosoma 

 Saundcrsii from Australia. The female, which was not hitherto 

 known, is remarkable for not having the body inflated as in the 

 male. 



Mr. Newport exhibited a new species of the genus Monodonto- 

 merus, belonging to the family of the Chalcid'idce, reared from 

 larvae which he had found in the nests of Anthophora retusa. Fie 

 proposed for it the name of Monodontomcrus nltldus.
