The President exhibited Micropus sabuleti, Fallen, an hemipterous insect new to 

 the British list, although taken several years since by Mr. WoUaston in Dorsetshire ; 

 it was also captured by Dr. Power, at Merton, in 1859, and by Mr. G. Lewis, near 

 Folkestone, in 1860. About one insect in twenty only has wings, a peculiarity noticed 

 by Fallen. 



Mr. F. Smith exhibited a living example of Aspidomorpha Sta. Crucis, a splendid 

 Cassida from India, lately received at the British Museum, and the only one of a 

 number sent which reached this country alive. 



Sir J. Hearsey observed that he bad frequently noticed this beautiful species in 

 India, and that when his family visited the sobterranean temples of Salselte they found 

 it in some abundance on the island. 



Mr. Waterhouse exhibited a series of specimens of Ceuthorhyncus sulcicoUis, GylL, 

 and a series of another species very much resemblint^ the C. sulcicoUis, but diflFering so 

 as to lead him to regard it as a distinct species. The first mentioned insect is common 

 in the London district, and is found on the Erysimum officinale and perhaps some 

 other plants ; the second insect Mr. Waterhouse had met with at Highgate, in the 

 neighbourhood of Box Hill, Surrey, and at Northfleet in Kent, always on the Ery- 

 simum AUiaria, and always unaccompanied by the C. sulcicoUis. Its most obvious 

 points of distinction consist in the constantly pitchy red colour of the tarsi, and the 

 under parts of the body and the sides of the chest being very sparingly clothed with 

 minute gray-white scales. In C. sulcicoUis the under parts are pretty densely clothed 

 with pale scales, and the little triangular plate on the side of the chest, which partially 

 separates the thorax from the elytra, is so completely covered with white or pale bufF- 

 coloured scales as to form a conspicuous pale spot at that part. These differences Mr. 

 Waterhouse had formerly noticed when comparing a certain Ceuthorhynchus, presented 

 to the British Museum by Mr. Walton, with the C. sulcicoUis, but at that time he 

 imagined Mr. Walton's insect (which was regarded by him as the C. tarsalis of Schon- 

 herr *) was a mere variety of the C. sulcicoUis ; he now finds, however, that the difi'er- 

 ences noticed are accompanied by others ; the red-fooled insect differs from C. sulci- 

 coUis in having the antennae longer, the thorax more coarsely punctured, the pointed 

 tul)ercles at the apex of the elytra less distinct, and the interstices of the striae sub- 

 granular. The tarsi, moreover, are shorter and stouter, and the femora are more 

 strongly toothed. The dark colour of the under parts, owing to the scarcity of scales, 

 forms a marked difference when the under side of this insect is compared with that of 

 C. sulcicoUis, and when the male sex of each species is compared more important 

 difierences are seen. In the male C. sulcicoUis the penultimate abdominal segment 

 has two approximated small tubercles, and the last segment is concave in the middle 

 third, the concavity being bounded on each side by a slightly raised ridge ; the chest, 

 moreover, is slightly concave ; in the other Ceuthorhynchus the chest is strongly con- 

 cave in the middle ; the penultimate abdominal segment is simple, and the concavity 

 on the last segment is bounded on either side by a well-marked conical tubercle ; the 

 under parts are likewise less thickly punctured. The C. picitarsis of Schonherr is 

 compared by its describer to the C. sulcicoUis, from which it differs in having the 

 tarsi pale ferruginous, and in having the under parts of the body very sparingly scaled, 

 and so far agrees with the insect to which attention is directed ; but C. picitarsis is 



* On a former occasion Mr. Waterhouse called the attention of the Society to what 

 he believed to be the true C. tarsalis.
