colour of the derm is tawny-rufous, and this is covered 

 by a fine and close tawny pubescence^ which is of a silky 

 golden-yellow hue in fresh specimens. On the head and 

 thorax this pubescence is tomentose, but on the elytra 

 and the under-surface of the body, it consists of very 

 fine short hairs. There are no long erect bristles, as in 

 many other species, but the antennae have the usual 

 fringe underneath the basal joints. The narrow black 

 lateral margin to the elytra occupies the groove formed 

 by the upturned lateral edge. It exists also in E. octo- 

 guttata, but is here rendered more conspicuous by the 

 light tawny-reddish hue of the surface.

Genus Eburodaceys.

Distinguished from Ehuria by the more abruptly cla- 

 vate form of the anterior femora, and especially by the 

 grooved third and fourth joints of the antennse. The 

 middle and hind femora are more elongate and slender, 

 and always terminated by a single elongate spine.* 



* Lacordaire gives the glabrous surface of the body as one of the 

 distinguishiug characters of Ebii/rodacrys, but E. sexm.aculata, E. citreo- 

 gidtata (Thorns.), E. longijnlis and others here described, are clothed 

 above with veiy long hairs. The foUowing fine large species also is thickly 

 clothed with long erect hairs.
