108 SUBFAMILY IX. OTIORHYNCHINyE. 



than in rigidus, scarcely reaching the hind border of eye, the latter distinctly 

 larger and more coarsely granulate than there. Thorax subglobose, as wide 

 as long, sides distinctly rounded; disc densely covered with large rounded 

 obtuse tubercles, each of which bears a small inclined pale hair, the median 

 impressed line distinct. Elytra oval, widest at middle, suddenly narrowed 

 on apical fourth; disc distinctly striate, the striae with rows of large round- 

 ed punctures; intervals convex, setose as in rigidus, the setae more 

 prominent on apical half. Under surface sparsely clothed with small scales; 

 femora and tarsi with numerous short setae. Length 4.5 5.5 mm. 

 (W. 8. B.) 



Crawford and Harrison counties, Indiana. Five specimens 

 taken May 28 June 24, from beneath chunks and stones in high, 

 dry open woods. A larger and more convex species than rigidus : 

 the beak distinctly broader and with much more evident trans- 

 verse groove at base ; thorax more globose and with the tubercles 

 of its surface much more prominent. It is evidently a species of 

 southern range, as both the counties in which it has been found 

 border on the Ohio River. 



Tribe III. OTIORHYNCHINI. 



In this tribe the antennae are rather long, the scape always 

 reaching beyond the eyes ; beak short, its antenna! grooves never 

 linear and at the same time directed obliquely downward ; elytra 

 striate, the strijp entire; side pieces of metasteruum usually en- 

 tirely concealed by the elytra. 



KEY TO EASTERN GENERA OF OTIORHYXCHIXI. 



a. Funicle 6-jointed; basal joint of antennal club very large. 



b. Intervals of elytra with very short almost invisible setae; antennal 



club oval; thorax without median sulcus; articular surface of 

 hind tibiae enclosed, their tips truncate with a broad oval space. 



VII. AGRAPHUS. 



lib. Intervals each with a row of prominent club shaped setae; club ob- 

 long; thorax with a deep median groove; articular surface ot hind 

 tibiae open, their tips not truncate. VIII. PARAGRAPHUS. 



aa. Funicle 7-jointed; articular surface of hind tibiae free, the corbels 

 open; basal joint of antennal club not greatly enlarged. 



c. Tarsal claws free. 



d. Outer joints of funicle longer than wide, obconical; eyes without 



orbital groove. 



e. Metasternal side pieces entirely concealed by the elytra, the sut- 

 ure obsolete; hind tibiae with two short fixed spurs; length 

 5 or more mm. IX. OTIORHYNCHUS. 



ee. Metasternal side pieces moderately wide, the suture distinct; hind 

 tibiae without terminal spurs; length not over 4 mm. 



X. NEOPTOCHVS. 



(Id. Outer joints of funicle short, rounded, moniliform; eyes with dis- 

 tinct orbital groove.
