(Subf. 2. RHYNCOPHORIDES.) 



Genus 113. SITOPHILUS. 



Schonherr, Gen. et Spec. Cure. iv. 967 (1838). 



Corpus parvum, sublineari-oblongum, depressum, sculpturatum : rostro elongato subarcuato sub- 

 deflexo, basi (ad antennarum insertionem) ampliato ; oculis oblongis : prothorace amplissimo, apice 

 coarctato : scutello distincto subrotundato : elytris planiusciilis, posterius angustatis, ad apicem 

 abdomine brevioribus : alis amplis. Antenna breviusculre validfCj prope basin rostri insertse ; scapo 

 robusto subclavato ; funiculo 6-articulato articulis primo et secundo longiusculis (illo crassiore), 

 reliquis brevioribus latitudine leviter crescentibus ; capitulo solido oblongo-ovato, apice obscure 

 aimulato et spongioso. Pedes validi, antici paulo longiores basi distantes : femoribus clavatis 

 muticis ; tibiis rectis, intus (prfesertim anticis) plus minusve crenulatisj ad apicem externum m 

 uncum magnum acutum deflexum productis ; tarsis reflexis. 



The SitopJiili may be easily known by their depressed and deeply-sculptiu-ed 

 upper surface, by their greatly developed prothorax and internally crenulated 

 tibiae, by their posteriorly narrowed and apically abbreviated elytra, by their 

 six-jointed funiculus, and by their antennae being inserted near the base of the 

 rostrum, — which is itself more or less thickened at the point of junction. In 

 their liabits they are purely granivorous, subsisting on different kinds of corn, 

 rice, and such-like articles of commerce, to which, especially in the larva state, 

 they are often very injurious : and hence it is that many of them have become 

 naturalized, as is the case with the following two species of the Madeu'^ Islands, 

 throughout the civilized world, — abounding, at times, in granaries, and other 

 receptacles of merchandise, in the larger cities and ports of nearly every country.
