somewhat grooved lines are deepest behind, and are punctured ; 

 the under side and legs are metallic green.

ZOPHEROSIS GEORGII. (PL LIX. fig. 6.) 



Z. subparallelus elongatus, carbonaceo-niger, subnitidulus ; ely- 

 tris ruffosissime tuberculatis, dorso generali elytrorum deplanato, 

 lateribus tubercidatis, ad sutiiram tuberculis minoribus, apice 

 elytrorum subdeclivi, tuberculis ante apicem maximis ; thoracis 

 lateribus rectiuscidis, paulo curvatis, antice posticeque extensis, 

 superficie dorsali valde irregularis medio postice sulco profundo 

 impresso, medio antice Icevi, parte Icevi postice sulcis angustis 

 profundis sinuatis marginata. 



Long. lin. 14 ; lat. max. elytror. pone medium lin. A\.

In general appearance this remarkable insect closely resembles the 

 species of the genus Nosodendron, particularly the N. morbillosum 

 from Chili ; but it evidently (as Mr. Waterhouse, who kindly exa- 

 mined it, and after whose Christian name its specific name is derived, 

 remarks) is closely allied to Zopherus, G. E. Gray. Like that genus, 

 it has the deep groove on the under side of the thorax, for the re- 

 ception of the antennae. This groove is widest at the end, and must 

 effectually screen these organs from injury. The antemise have the 

 first eight joints with the inner edge straight, and forming a con- 

 tinuous line, while the outer edges of each of these joints are some- 

 what rounded, and give a moniliform appearance to the outer edge ; 

 the second joint is the smallest, it is very short, and widish compared 

 with its length ; the third joint is considerably longer than the joints 

 from the fourth to the eighth ; the three terminal joints form a short 

 club, the sides of which have two notches, caused by the middle part 

 of each joint across being the widest and the sides tapering to this 

 point. The thorax and elytra are very like those of some species of 

 Nosodendron ; the tarsi, on the under side, have a widish groove, 

 each of the sides of which have a keel ; the prothorax below has a 

 deep curved sulcus close to the margin, and two faint grooves behind 

 it, and the sternal plate between the fore legs, which plate has on 

 each side of the trochanter a curved groove, neatly impinged on the 

 outer side. 



The species of Zopherus are all from the New World ; and as 

 there are several species which agree together, others from Australia 

 may be found agreeing with this : it may be called Zopherosis. The 

 last segment of the abdomen has on each side a deep transverse bi- 

 sinuated groove. This may possibly be sexual ; but as the Museum 

 only possesses a single specimen, I cannot tell. 



DiSTICHOCERA. 



In the Proceedings of this Society, Mr. Newman, two or three 

 years ago, described the species of this genus. I here add the de- 

 scription of a new species.
