Genus 49. RHYZOPHAGUS. 
Herbst, Kaf. v. 18. tab. i. f. 7-9 [script. Ryzophagus | (1793). 
This common European genus being an addition to the Madeiran 
fauna since the publication of the Jnsecta Maderensia, we may just 
state that it differs from the typical Mitidulide in its antenne being 
only 10-articulate, and in the tarsi of its male sex being hetero- 
merous ; its labrum moreover is concealed. The species of which it 
is composed are narrow, linear, and free from pubescence ; and their 
elytra are truncate at their apex. At first sight it somewhat ap- 
proaches the Madeiran Hurops (of the Colydiade); but the many 
and important characters which distinguish it therefrom may be at 
once gathered by a reference to the observations under that genus.
