IphimcisfulvicoUis, sp. n. 



Below black, the head, basal joints of the antennas and the thorax 

 fulvous, the latter very minutely punctui'ed : elytra finely semi- 

 pvinctate-striate, dark violaceous Ijlue.

Fern. Broadly ovate, the head with a few extremely minute 

 punctures, reddish fulvous, the middle witli a short longitudinal 

 depression, epistome triangular, its anterior edge but slightly concave, 

 the surface very finely punctured, labrum broad, fulvous, antenna?

 longer than the second joint but shorter than the fourth, terminal 

 joints slightly thickened ; thorax twice as bread as long, narrowed 

 anteriorly, the sides rounded ; the angles acute, anterior margin 

 concave, posterior one rounded, the surface sparingly and scarcely 

 perceptibly punctured, scutellum dark fulvous ; elytra not wider

I only know a single specimen of tliis species, distinct 

 from any of its allies by the colour of the head, thorax

 easily mistaken. 



This group contains at present nearl}^ thirty genera, and
