CLASSIFICATION OF THE RHYNCHOPHOROUS COLEOPTERA. 459 
der, tibiæ feebly mucronate at tip; tarsi dilated, brush-like be- 
neath, claws separate. 
This species is from 10—11™™ -4—-45 inch long, black, densely 
clothed with small cinereous scales, with lateral and dorsal vitte of 
the prothorax, and scutellum pale yellow; the prothorax is sparsely 
punctured, and the elytra very feebly striate. I have named the 
genus Evotus. It is the Otiorhynchus? naso Lec. (Pac. R. R. 
Expl. and Surveys, p. 56). 
The second of the anomalous forms above mentioned is a small, 
roughly tuberculate insect of the southern part of California, 
found under bark of yucca. It resembles in appearance the Euro- 
pean Rhytirhinus, and shows unmistakable Byrsopide affinities. 
The mentum is, however, similar to that of the other Adelognaths 
of the present family, and the apical scar of the mandibles is dis- 
tinct, flat and subtriangular, though without the central elevation 
usually seen. The tarsi are less dilated than usual, and sparsely 
ciliate beneath; the 3d joint is emarginate rather than bilobed, 
the claws separate. The rostrum is moderate in length, thick, 
irregular, not emarginate at tip, prominent above the eyes; the 
antennal grooves are deep and descend obliquely below the eyes 
which are pointed below, oblique and transverse. The scape of 
the antenne extends nearly to the eyes; the funiculus is longer 
than the scape, 7-jointed as usual, with the 1st and 2d joints a lit- 
tle longer ; club oval, pointed and annulated as usual. Prothorax 
strongly lobed behind the eyes, feebly emarginate beneath, broadly 
flattened (but not excavated) in front of the coxe. e side 
Pieces of the metathorax are not distinct, the 1st and 2d ventral 
Segments are large, connate by a sinuated suture ; 3d and 4th short, 
dth longer than the 3d and 4th united, with a broad impression 
each side near the margin. 
ogini, represented by two species in‘ the southern Atlantic States. 
The form resembles somewhat the Tanymecini, but is rather 
stouter and more convex; the color is black adorned with narrow 
stripes and bands of metallic scales.
