lateral fovea. The elytra have the small asperate punctures 

 distinct and moderately close together ; the spots on the alter- 

 nate interstices are very obscure. 



Gymnopleurus signaticollis. 



Obscure fusco-seneus, surdus, brevissime flavo-griseo-pilosus; thorace 

 antice oblique angustato, crebre granulate-, maculis circiter octo 

 nitidis ameis ornate, basi bifoveolato, lateribus baud serrulatis, 

 angulis posticis rotundatis; elytris subtilissime coriaceis, crebre 

 Bubtiliter granulatis, striis vix impressis. 



Long. 12 millim. 



Hob. Nubia. 



This species is very close to G. maculosus, McLeay, but is 

 quite differently coloured and has no spots on the elytra. The 

 head is rather closely punctured. It has four teeth in front 

 (besides the obtuse angle of the lateral lobe) , the outer ones 

 obtuse. The thorax is obliquely narrowed in front, broadest 

 before the hind angles, which are rounded and not so produced 

 as in G. maculosus • the surface is dull, dotted with very 

 small shining granules, which are rather close together; 

 there are two very distinct foveas at the base and the lateral 

 fovea is also very distinct ; there is a small, smooth, shining 

 green spot in the middle and another between this and the 

 base, and on each side of the disk are three very irregular 

 shining spots. The elytra are rather flattened, with very 

 obscure strias, dull, dotted with minute shining granules, 

 which are rather close together. The metasternum is decli- 

 vous, rather closely punctured. 



Gymnopleurus Reichei. 



Fusco-niger, opacus ; capite sat crebre granulato, antice triangu- 

 lariter inciso ; thorace ante medium oblique angustato, postico 

 subparallelo, confertim subtiliter rugoso, antice granulis nitidis 

 asperso, disco ct basi medio impressione notatis ; elytris coriaceis, 

 obsolete striatis, iuterstitiis secundo et quarto parum convexis, 

 granulis minutis aspersis ; metasterno sat crebre punctato, medio 

 paulo inflate. 



Long. 11 millim. 



Hab. Abyssinia. 



This species is allied to G. maculosus, but has much the 

 appearance of G. mopsus, The head as in G. mopsus, but a 

 little narrower and with a more distinct angular emargination 

 in front ; the raised lines are the same ; the granulation is a 

 little more distinct. The thorax is more convex, more finely 

 rugose, more distinctly angular in the middle of the sides,
