TRIBE IV. PHYLLOBI1NI. 



129 



cc. Beak very short and stout, its nasal plate large, as wide as beak 



and distinctly margined. XXVII. SCYTHROPUS. 



l>b. Elytra at base not wider than thorax, emarginate or truncate; hu- 



meri absent or rounded; wings absent or rudimentary. 

 d. Antennae scaly or coarsely pubescent; body beneath rather densely 



scaly; length 4 or more mm. 



e. Antenna! grooves curved downward and directed toward the 

 constriction between the head and beak; elytra robust, oval. 



XXVIII. SCIAPHILUS. 

 ee. Antennal grooves directed towards and just beneath the eyes; 



scape not passing the eyes, which are very prominent. 



XXIX. STROPHOSOMA. 

 (Id. Antennae shining, sparsely hairy; body beneath nearly naked; 



smaller, not over 3 mm. XXX. BARYPEITHES. 



XXY. PHYLLOBIUS Germar, 1824. (Gr., "leaf ' -f "living on/') 

 Beak as long as and somewhat narrower than head ; eyes oval, 

 slightly oblique; antenna? long and slender, scape 

 reaching the front of thorax, joints 1 and 2 of fnni- 

 cle longer, the second longer than first, 3 7 sub- 

 equal, obcouical ; scutellum distinct; second ventral 

 not as long as the two following united, its front 

 suture nearly straight. One introduced European 

 species occurs in our territory. (Fig. 51.)

167 (8332). PHYLLOBIUS GLAUCUS Scop., 1763, 31. 



Elongate-oblong. Black, shining; head and thorax 

 rather densely, elytra very sparsely clothed with bluish- 

 ( After Kuhnt.) green scales; antennas and legs pale reddish-brown. Head 

 and beak as long as thorax, densely punctured. Thorax oval, one-half 

 broader than long, narrower at apex than base, sides strongly rounded, disc 

 convex, rather densely and finely punctured. Elytra oblong, wider at base 

 than thorax, sides parallel for four-fifths their length, then suddenly con- 

 verging to an acuminate apex; strial punctures rather large, close-set; in- 

 tervals feebly convex, finely and sparsely punctate. Femora rather strong- 

 ly toothed on the inner side. Length 5.5 7.5 mm. 



Recorded from Canada. Gyllenhal states that in size, color 

 and vestiture European specimens are extremely variable. 



XXVI. POLYDRUSUS Germar, 1817. (Gr., "many" -j- "dewy.") 



In this genus, with which CypJioni'ninis Horn of the Henshaw 

 catalogue has been combined, the beak is a little shorter and nar- 

 rower than the head, its tip feebly notched ; autennal groove deep 

 in front, suddenly bent and passing beneath the eyes, the latter 

 round; antenna? long, slender, joints 1 and 2 of funicle longer, 

 3 7 obconical, gradually decreasing in length ; club elongate- 

 oval ; inner wings present. Three species, two of them European, 

 have been taken in the Eastern United States.
