NO. 1708. STUDIES OF NORTH AMERICAN WEEVILS— PIERCE. 351 



head and beak coarsely and densely punctate ; beak tricarinate above ; 

 eyes separated by much less than twice their own width; antennal 

 scape not reaching posterior margin of eyes, first funicular slightly 

 longer than second, second not as long as the two following. Pro- 

 thorax as wide as long, sides strongly and evenly arcuate; ocular lobes 

 not nearly as densely fimbriate as in tumida; disk broadly and rather 

 deeply impressed along median line, also with three large round 

 impressions on each side of the middle, the central pair closer together 

 than the others, disk rather closely covered with strong polished 

 tubercles. Elytra with sides subparallel, slightly the widest at 

 apical third; disk with alternate intervals strongly elevated, tuber- 

 culose, bristling with curved spines, most prominent at apical decliv- 

 ity, which is almost vertical in profile; striae unimpressed, punctures 

 moderate in size, each with a large scale, surface not conspicuously 

 tuberculose. 



In all other respects the phraseology used in the description of 

 tumida will fit this species. It differs from all other Amnesia by the 

 squamigerous serial punctures, thus resembling Dyslohus. It is 

 arranged with Amnesia because of the alternate elevated intervals.
