MYLL^ENA. 
M. pal/nensis, sp. nov. (2). Fusca; subtiliter pubescens ; antennarum basi, 
pi'othoi’ace elytris et abdominis segmeutis apicalibus 2 pallidis; prothorace quam 
elytra uullo inodo augustiori, antice leviter aiigustato, lateribus manifeste arcuatis; 
elytris prothoraci longitudine lequalibus; pedibus testaceis. Long. 14 1. 
Coloured differently from any other Mylhena known to me. The head and 
front part of abdomen are blackish fuscous, the prothorax and last two segments 
very pale fuscous (almost whitish); the elytra very little darker. Compared with 
M. intermedia, Er., this species is markedly larger, with the prothorax larger in 
proportion, fully as wide as the elytra, and with its sides distinctly rounded.
