146 SUBFAMILY X. CURCULIOXIX.E. 



luni very small; pygidium not exposed; front and middle coxa? 

 round, the latter narrowly separated ; hind tibire truncate at tip, 

 the articular surface terminal or oblique; claws simple, usually 

 separate. The first two of our genera have been recently mono- 

 graphed by 



Titus. E. G. "The Genera Hypera and Phytonomus in Amer- 

 ica north of Mexico," in Ann. Ent. Soc. Amer., IV, 1911, 

 383473. 



KEY TO GEXERA OF HYPERIXI. 



a. Ventral segments not very unequal; post-ocular lobes of thorax ab- 

 sent ; eyes separated by not more than their own diameters. 

 &. Articular surface of hind tibiae, terminal, well defined; smaller, not 



over 8.5 mm. 



c. Beak shorter than thorax; mandibles never emarginate; thorax 

 much narrower than elytra, the latter strongly convex. 



I. HYPEKA. 



cc. Beak longer than thorax; mandibles emarginate; thorax not more 



than one-third narrower than elytra, the latter more elongate, 



much less convex. II. PHYTOXOMT'S. 



1)1). Articular surface of hind tibiae oblique, ill defined; size large, 9 or 



mere mm. III. LEPYRUS. 



aa. Ventral segments very unequal, the third and fourth short, united 



equal to one of the others. 



d. Second joint of funicle much longer than first; tibia? strongly 

 mucronate; larger, usually more than 5 mm. in length. 



IV. LISTKONOTUS. 



M. Second joint of funicle as long as or but little longer than first; 

 tibia? feebly mucronate; smaller, seldom over 4.5 mm. in length. 



V. HYPERODES. 



I. HYPERA Germ., 1821. (Gr., "a cord.") 

 To this genus there is known from our fauna only the single 

 introduced European species : 



184 (8427). HYPERA PUXCTATA Fab., 1775, 150. 



Oval, robust. Piceous black, everywhere finely and densely punctate; 

 thickly clothed with gray scales having a metallic lustre (var. opimus 

 Lee.) or with brown, yellow-brown or blackish-brown scales which are 

 short, broad and emarginate at tips, also with numerous short suberect 

 bristles; edge of elytra yellow-brown or at least paler then the disc. Beak 

 two-thirds the length of thorax, its under surface, sides and tip above, 

 polished. Thorax one-third wider than long, sides rounded at middle, then 

 feebly converging to base. Elytra one-fourth longer than broad, sides paral- 

 lel for three-fourths their length, thence broadly rounded to tips; striae 

 finely punctate, the sutural and each alternate interval wider and slightly 

 more elevated than the others. First ventral segment of male impressed 

 and emarginate behind. Length 5 8.5 mm. (Fig. 58.)
