 ' Monograph of the larger African Species of Nocturnal Lepidoptera, belonging or 

 allied to the Genus Saturnia,' with four plates ; by J. O. Westwood, Esq., the author. 



The following gentlemen were balloted for and elected Corresponding Members 

 of the Society : Herr M. Bach, Boppard, on the Rhine ; H. G. Dalton, Esq., George 

 Town, Demerara. 



Mr. Westwood exhibited a specimen and drawing of Cholovocera Maderae, a new 

 Coleopterous insect, remarkable for having the facetted eyes at the posterior angles of 

 the head, replaced on each side by six small, semiglobose, pellucid ocelli, precisely si- 

 milar to the ocelli at the sides of the head of many larva), being the only species 

 throughout the whole of the metamorphotic winged insects in which this peculiarity 

 had been observed to exist. 



Mr. Westwood exhibited two insects mounted on gelatine, which he considered 

 was preferable to talc, as it was more transparent, and the insects were more firmly 

 secured, for the gum by which they were fastened was not so liable to scale off. 



Mr. Westwood also stated that the pupa-cases exhibited at the last meeting by 

 Mr. Bond, and then supposed to be those of a species of Galeruca, belonged to a spe- 

 cies of Chilocoris, and had been noticed by De Geer. 



Mr. Stainton exhibited a British species of Micropteryx which he had previously 

 overlooked, though it was described by Mr. Stephens under the name of concinnella. 

 It appeared that this species was the true Aruncella of Scopoli, and that the insect 

 described under that name by Mr. Stainton, in his monograph of the genus, must now 

 resume the name of Seppella, Fab. The females of both species, being destitute of 

 markings, would probably be very difficult to distinguish from each other. 



Mr. S. Stevens exhibited some beautiful new species of butterflies he had recently 

 received from Mr. Wallace, by whom they were captured, at Santarem, on the Ama- 

 zon river: among them he had been able to identify Callithea Godartii, Feisthamel 

 (male and female), and C. Lepreurii, Feisth. He also read an extract of a letter 

 from Mr. Wallace, stating that the males of C. Godartii frequent the higher parts of 

 trees, and are very difficult to capture. 



Mr. Douglas exhibited an empty pupa, apparently of some Noctua, in a thistle- 

 stem of last year, and some living larva, found the preceding week, at Darenth 

 Wood, on broom. These larvae, which did not seem to be scarce, drew together se- 

 veral of the smaller twigs of the broom, forming a covering, in which they appeared 

 to have hybernated, and in which tbeyfed on the bark: they resembled in appearance 

 and habit the larvae of Depressaria assimilella, as described by Fischer-von-Rosler- 

 stamm. 



Mr. Douglas exhibited a new species of Elachista, which he proposed to name 

 occultella, and of which he read the following description : — 



Family Tineid2E. 

 Elachista occultella. 



Caput fuscum ; antenna? nigrae; thorax niger; alae anticae nigrae griseo irrorats, 

 medio fascia laevi obscura, maculis duabus oppositis griseis, apicibus ratione 

 ciliorum rotundatis. Alae posticae nigrae, ciliis fuscis.
