female reaching beyond the tip of wing-cases ; that of male not much 

 beyond the elbow of middle femora and tibia?. Thorax with a few sliort 

 stiff hairs springing from slight conical elevations. Wing-cases showing 

 the striae and humps of future beetle, the tip of the upper case usually 

 terminating in a thorn. The nine abdominal joints deeply and distinctly 

 separated, the first showing a rounded scuttellar tubercle ; the sides 

 angular, conically ridged, and armed on each joint with two brown 

 thorns or bristles, which become stouter towards apex; a transverse

 other fruit snout-bectles. I have had the beetle in my cabinet 

 for several years, but knew nothing of its larval history until a

 and having very much the same form, as may be seen by 

 referring to the figure (Figure 9), yet it differs remarkably in 

 its habits fi'om both of the preceding weevils. It is, like
