 above ; head slightly constricted with a very short neck ; antennae 

 long, intermediate joints of the antennae pubescent, the three basal 

 ones very densely pilose, and also with long bristles, the first one 

 nearly as long as the three following, the others elongate ; prothorax 

 narrowed diagonally laterally from the median part to the base, 

 which is very narrow, disk quite plane ; elytra pedunculate at the 

 base, elongato-ovate, very plane ; legs moderately long ; femora 

 clubbed ; tibiae compressed at the tip, not fossorial ; tarsi pubescent

Siagonn occurs in Europe, Africa, and the Indian Peninsula. It 

 is worthy of notice, as pointed out by De Chaudoir in his ' Mono- 

 graphie des Siagonides,' Bull. d. Mosc, 1876, p. 18, that they are 

 eminently continental insects, having not yet been found in any 

 of the islands round Asia or Africa, and the Oriental continental 

 limit seems to be the river Mekong.
