456 CLASSIFICATION OF THE RHYNCHOPHOROUS COLEOPTERA. 
The second group is represented by two species on the Atlantic 
slope, belonging to Epicaerus and Graphorinus ; the body is pyri- 
form and robust; the accessory mandibular pieces are not pre 
served in any of my specimens, but the process which supports 
them is longer and more prominent than in any other group. 
With the tribe Leptopsini, and the anomalous Rhigopsis de 
scribed below, the series having the side pieces of the metathorax A 
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 eyes are more or less transverse and pointed below, 
nearly round in Phyxelis. The beak is moderate or rather long, 
sometimes wider at tip, and auriculate (Hylobius? torpidus Let. 
and Tyloderes? gemmatus Lec.,) 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, Ca 
indicating a new genus. I have a remarkable 9 specimen of E ue 
torpidus, having but 4 ventral segments, one of the two short seg- 
ments being wanting. os 
The second great division of the Otiorhynchide, in which as 
side pieces of the metasternum are well defined, though alwa, 
narrow, may be separated into two principal types, according ° 
the form of the beak. 
In the first, the beak is moderate, or rather long; more OF 
thickened, with the antennal grooves (as in all the preceding 
somewhat visible from above, and either directed towards the 
or obliquely downwards; the prothorax is truncate at bene 
elytra are connate, and the humeri are rounded. The eyes 
in form, and the prothorax is either lobed or not, according, 
eyes are transverse or rounded.
