456 CLASSIFICATIOX OF THE RHYNCHOPHOROUS COLEOPTERA. 



The second group is represented by two species on tlie> Atlantic 

 slope, belonging to Epicaerus and Grapliorinus ; the bod}^ is pyri- 

 form and robust; the accessory mandibular pieces are not pre- 

 served in an}' of ra^' specimens, but the process which supports 

 them is longer and more prominent than in any other group. 



AVith the tribe Leptopsini, and the anomalous Rhigopsis de- 

 scribed below, the series having the side pieces of the metathorax 

 indistinct or invisible is concluded. They differ essentially by 

 the outline of the front margin of the prothorax being sinuous 

 when viewed laterally, so as to form a broad lobe for the protec- 

 tion of the eyes, when the head is deflexed ; and correlative with 

 this the tip of the prosternum is broadly- and feebly emarginate. 

 The ej'^es are more or less transverse and pointed below, though 

 nearl}' round in Phyxelis. The lieak is moderate or rather long, 

 sometimes wider at tip, and auriculate (Hi/lobius? torpichis Lee. 

 and Tyloderes? gemmatus Lee.,) very much as in Otiorhynchus. 

 The antennal grooves are visible from above, but descend obliquely, 

 towards the inferior angle of the eye, which however they do not 

 reach. Panscopus and Phyxelis represent this tribe in the At- 

 lantic States, and also a species which I refer to Strangaliodes ; 

 the Pacific representatives are the two species above named, each 

 indicating a new genus. I have a remarkable 9 specimen of 77. ? 

 torj^idus, having but 4 ventral segments, one of the two short seg- 

 ments being wanting. 



The second great division of the Otlorhj^nchidsP, in which the 

 side pieces of the metasternura are well defined, though always 

 narrow, ma}' be separated into two principal types, according to 

 the form of the beak. 



In the first, the beak is moderate, or rather long, more or less 

 thickened, with the antennal grooves (as in all the preceding), 

 somewhat visible from above, and either directed towards the eyes, 

 or obliquely downwards ; the prothoi-ax is truncate at base, the 

 elytra are connate, and the humeri are rounded. The eyes vary 

 in form, and the prothorax is either lobed or not, according as the 

 eyes are transverse or rounded. 



Apical process of mandibles pyramidal, acute : 

 Tibi« with a terminal hook, ........ Dj^slobi. 



Apical process not prominent : 

 Tibiae normal, truncate at tip, ...... Ophryastes. 



Tibiae expanded at tip, Trigonoscutae. 



In the second type the beak is flat above, usually channelled.
