nated in the middle of the internal surface. The four antei-ior 

 tarsi are five jointed, the first three large, more especially in the 

 male, the two last long and slender, the last very long. 



There are several species which will come under this genus, 

 which have been described by the late Rev. Hamlet Clark as 

 Hi/dropoii, such as H. penicillatus, WoUastonii, dispar., Sfc. 



The shape, however, of the anterior legs and the five jointed 

 tarsi, necessitate their removal into another genus. 



168. — Necterosoma vittipbnne. n. sp. 

 Length 2 lines. 

 Ovate, broad, subconvex and of a yellow colour. Head with 

 a shallow slightly elongated fovea on each side in front. Thorax 

 broad, short, and bisinuate at the base, vpith the basal lobe 

 rounded, the posterior angles acute, the anterior angles advanced, 

 the apical border brown, the basal border also bi'own and enlarged 

 into two spots about midway between the centre and the posterior 

 angles, and with a small striola at the base on the outer side of 

 these brown spots, and a series of smaller striola along the whole 

 basal border. Elytra dark brown, with five yellow vittee on 

 each side of the suture, extending from the base to the apex, with 

 large spots of the same colour on the sides, and with one or two 

 oblique striolse on the scutellar region, giving the appearance of 

 a large scutellum. 



169. — Necterosoma flavicolle. n. sp. 

 Length 1| lines. 

 This species differs from the last in having the frontal de- 

 pression more round and very shallow, in having the thorax 

 entirely yellow, with a depression at the base equidistant from the 

 centre and the posterior angles, in which are three or four small 

 but distinct striolae, and in having the elytra without striolse on 

 the scutellum region, and of a yellow colour, with a series of six 

 vittse, and some lateral spots, brown, the second vitta from the 

 suture being abbreviated towards the base and apex. The elytra 

 also are quite acuminated at the apex, much more so than in N. 

 viUipenne.
