CLASSIFICATION OF THE RHYNCHOPHOEOUS COLEOPTERA. 459 



der, tibiae feebly mueronate at tip ; tarsi dilated, brush-like be- 

 neath, claws separate. 



This species is from 10- ll""™ -i-Ao inch long, black, densely 

 clothed with small cinereous scales, with lateral and dorsal vitt?e of 

 the prothorax, and scutellum pale j'ellow ; the prothorax is sparsely 

 punctured, and the elytra very feebly striate. I have named the 

 genus Evotus. It is the Otiorliynclius? naso Lee. (Pac. R. R. 

 Expl. and Survej^s, 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 3'ucca. It resembles in appearance the Euro- 

 pean Rhytirhinus, and shows unmistakable Byrsopide aftinities. 

 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 63^68 ; the 

 antennal grooves are deep and descend obliquely below the eyes 

 which are pointed below, oblique and transverse. The scape of 

 the antennpe 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 e^^es, feebly emarginate beneath, broadly 

 flattened (but not excavated) in front of the coxae. The 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, 

 oth longer than the 3d and 4th united, with a broad impression 

 each side near the margin. 



The species is of small size (S'S""") brown, covered with a dirt 

 colored crust, very roughly reticulate above, with large deep pits ; 

 the humeral angles are sharp and prominent ; there is a large tu- 

 bercle on each el3^tron about ^ from the tip, and another smaller one 

 near the tip. I have named this singular insect Wiigojjsis effracta. 



The last tribe having an apical sear to the mandibles is Eudiag- 

 ogini, represented by two species in the southern Atlantic States. 

 The form resembles somewhat the Tan3nnecini, Init is rather 

 stouter and more convex ; the color is black adorned Avith narrow 

 stripes and bands of metallic scales.
