252 Mr. M. Jacoby on 



from the Belgian Museum. The insects may perhaps 

 best be compared to C. laticolle, Lefev., on account of the 

 laterally broadened thorax, but the entire colour is dark 

 bronze or aeneous and the sculpturing of the upper surface 

 is quite different, the same parts are also very shining and 

 not subopaque, the colour of the legs does not differ from 

 that of the body and the anterior femora are armed with 

 a distinct tooth ; the penis of C. laticolle is not produced 

 into a long point but is suddenly constricted at the apex 

 into a short tooth. 



Corynodes auripes, sp. n. 



Greenish-blue, head and thorax minutely punctured, very shining, 

 elytra subopaque, finely punctured in irregular rather distant rows, 

 legs metallic greenish-cupreous, claws appendiculate. 



Length 12 millim. 



Head finely punctured, very convex, the supra ocular sulci very 

 broad and deep, impunctate, clypens separated by deep grooves, 

 wedge-shaped, closely and not very strongly punctured and finely 

 pubescent, labrum greenish, mandibles black, antenna? not extending 

 to the middle of the elytra, the lower five joints cupreous, the rest 

 dark purplish, very broadly dilated, thorax subcylindrical, rather 

 long, the lateral margins straight, the disc very closely and finely 

 punctured intermixed with numerous larger punctures, the surface 

 of a brassy greenish tint, much more shining than the elytra, the 

 latter greenish -blue, with double or treble very irregular rows of fine 

 punctures, the interstices aciculate, the breast and the legs metallic 

 green, the tibiae and tarsi more or less cupreous, abdomen dark blue, 

 closely punctured ; the penis is short End strongly curved, the apex 

 strongly rounded and rather suddenly pointed, the upper cavity 

 short and broad. 



Hob. Bibi, Bahr el Gazal (Coll. Belgian Mus. and my 

 own). 



I know of no African Corynodes of similar coloration in 

 connection with the elytral sculpture. 



Corynodes varicolor, sp. n. 



Obscure cupreous, violaceous or blue, the head sparingly punctured, 

 the thorax elongate, scarcely perceptibly punctured, elytra rather 

 finely, closely and regularly punctured, the punctures more closely 

 and irregularly placed near the apex, claws appendiculate. 



Length 10 millim.
