This, the largest of the Florissant species, differs strikingly from the 

 others and from all modem species known to me in the great length (if the 

 head, as well as in the great length and looseness of the antennal duh, so 

 that I ([nestion whether it shoidd fall here. The general form appears to Ije 

 as in the gronp Ventricosum. The head is considerably longer than the 

 thorax and longer than broad, tapers with full sides and rounded front nea)ly 

 from the base, and is nearly smooth but transversely wrinkled; the rostrum 

 is only ;i littlr longer than the head, very stout (for Apion) and equal, scarcely 

 aiTuatc, well rouiidi'd at the tip, with no expansion except at extreme ba.se; 

 the loose club occupies nearly two-fifths of the anteiuKV, which are longer 

 than the beak by the length of the apical joint. Thorax very short and 

 transverse, broadest at the base but scarcely tajiering, a little arched al)ove, 

 the surface very distantly, rather coarsely but not heavily punctate. Elytra 

 not clearly and fully jireserved in any specimen, but the striation appears 

 to be feeble, and their punctuation rather coarse. Legs with very stout and 

 large fore femor;i, but in no way abruptly clavate.
