Smooth, ccneous-black : antennce clavate ; head and thorax strongly punc- 

 tured, the latter depressed, subquadrate : elytra minutely punctured and 

 exceedingly finely pubescent. 



One from Conception. 



Family. CLERIDyE. 



*54. Necrobia kufipes. Fab. 



A blue variety of this species was common at Gorrite; indeed it seems to 

 be found all over the world. 



I may here observe that I have seen only one species of Corynetes*, which is 

 the violaceus of Fabricius ; it is the type of his genus, and is distinguished by 

 5-jointed tarsi and a linear club of 3 nearly equal joints, whereas *Necrobia 

 rtifipes and its congeners have 4-jointed tarsi and an obovate club of 3 joints, 

 the terminal one being very large, and the palpi are different ; notwithstanding 

 which the Baron Dejean includes them all in one genus under the name of 

 Corynetes.
