eleven joints, the fifth to the tenth produced at the apex on one 

 side ; prothorax smooth, very narrow in front, dilated behind ; 

 elytra narrow, gradually diminishing from the base ; legs long, 

 the posterior compressed. 



Nearly allied to Strangalia, but the antennae will at once dis- 

 tinguish it. 



Ocalemia vigilans. (PI. XXVI. fig. 3.) 



O.atra.nitida, prothorace iridescente; elytris subtiliter punctatis, 

 singulis maculis tribus flavis basi longitudinaliter dispositis.

 known Chinese traveller, to whom we are indebted for this and 

 many other novelties.
