254 Mr. C. O. Waterliouse on Coleoptera 



has the second costa furcate at the apex, but this is probably 

 an individual character.]. The abdomen is moderately 

 strongly punctured, the punctures not crowded; seneous, 

 with coppery shade, the extreme margins of the segments 

 steel-blue. The femora are dark bluish green; the tibiae 

 violet. 



Long, 21 lin. 



Hab. Samburu, Brit. E. Africa (C. Steuart Betton). 



POLYCESTA. 



By the kindness of M. Oberthiir I have been able to 

 examine all the types of Gory, Thomson, &c. in his collection. 

 Ifnfortunately some of the labels had manifestly been put 

 on the wrong specimens before they came into M. Oberthiir's 

 possession. I hope the following notes will be useful in 

 elucidating the synonymy, but until more specimens from 

 exact localities are available much doubt must still attach to 

 the names of several species. 



Polycesta cyanipes, Fabr. 



The type of this species is in the Hunterian Collection in 

 the University of Glasgow. It is P. resplendens, Th., from 

 Jamaica. Specimens labelled cyanipes, ¥., from Capt. 

 Kerremans' collection are the true depressa, Linn. 



Polycesta costata, Sol. 



Polycesta costata^ Sol., Gay's Hist. Chile, iv. p. 491 (1854). 



Mr. Saunders, in his Catalogue, places this next to carnifex. 

 Capt. Kerremans does not mention it. From description it 

 appears to me to be an unspotted variety of carnifex. If 

 this surmise is correct the name costata will have priority. 



Polycesta porcata, Fabr. 



The species for which this name is being retained in the 

 Museum is one of the broadest species of the genus, brownish 

 coppery, with dark green tint on the costae, with most 

 coarsely pitted elytra. Apparently common in St. Domingo. 



Polycesta thomce, Chevr. 



The type of this species is in the Museum. It resembles the 

 preceding, but the punctures or pits on the elytra are rather 

 smaller, rather more regular^ and consequently the costse 

 are more evident. 



It is not the same as P. Goryi, Saund.j as given by 

 Ciipt. Kerremans in Wytsman's 'Genera.^
