Tlie single European species at present contcained in this tribe very 

 much rcseniblesabioadandrolmst I\Iy]lse.ia; tlie tribe is eliaracterized l^y 

 having all tlio tarsi three-jointed ; it has already been discussed in connec- 

 tion with Myllmia and Gymnum.

In general appearance, as above stated, the species belonging to this 

 genus bear a strong resemblance to 3It//hena, but besides the difference 

 in the number of joints in the tarsi, the labial palpi are much shorter 

 and consist of three joints; the form, moreover, is broader, and is inter' 

 mediate between Myllcena and Gymnusa, from which latter ^enus 

 iJemopsis IS distmguished by the shorter, three-jointed, tarsi, the\ead 

 much less narrowed m front, the penultimate joint of the maxillary pnli.i 

 being more plainly thickened, the broader and more compressed tibiae 

 much shoiter tarsi, &c. ; the genus at present contains twelve species' 

 four from South America, two from Central America, two from North 

 America, and one each from Australia, Japan, Ceylon, and Europe.

 elytra; elytra a little longer than thorax, very finely and thickly 

 punctured ; hmd body comparatively short, rather strongly and o-radually 

 narrowed behind, very finely shagreened; legs dark With the taisi
