in another so closely allied as aiictiis, affords another instance, if 

 further proof were necessary, of the comparatively slight value 

 possessed by this character, and to indicate the propriety of unit- 

 ing the Anthonomini and Tychiini, which are at present separated 

 mainly upon this character, but in which the mutual similarity in 

 all other structural features, including habitus, is so pronounced.

Southern California. This species is somewhat isolated and con- 

 stitutes a small section, characterized by the rather shorter second 

 funicular joint which is scarcely as long as the next two together, 

 and by the unusually long slender scape. The form is rather robust 

 and subc3'lindrical, and the pronotum is broadly impressed along 

 the middle, finely, roughly sculptured and sparsely tuberculose to- 

 ward the sides, especially in the female. Length 1L4-13.5 mm. ; 

 width 4.0-4.5 mm.

Colorado — LeConte. Easily recognizable in the small section to 

 which it belongs by its comparatively large size, and the other 

 characters given in the table. Length 9.3 mm.; width 3.1 mm. 



6 L.. amplexus n. sp. — Rather slender, convex, cylindrical, black and 

 polished tliroughout, the antennae rufescent; pubescence very short, sparse, 

 feebly, sparsely nucleated on the elytra, the lateral vitta of the pronotum and 

 elytra continuous, narrow, extremely dense and pure vphite. Head and beak 

 finely, not very densely punctate, the punctures fine and with others slightly 

 coarser, with a deep rounded fovea between the eyes and another, much 

 elongated, between the antennae ; beak cylindrical, feebly arcuate, rather 

 stout, about three-fourths as long as tlie prothorax. Prothorax very nearly 

 as long as wide, the sides nearly parallel and just visibly arcuate to apical 

 fourth, then more convergent and feebly constricted to the apex, which is 

 truncate and about three-fifths as wide as the base, tlie latter transverse, 

 feebly but abruptly lobed in the middle ; disk with a small but deep and 

 distinct ante-scutellar impression, coarsely, deeply, rather closely and un- 

 evenly punctate, the interspaces polished, finely, sparsely punctulate. Elytra 

 a little more than twice as long as wide, two and one-half times as long as the 

 prothorax, and, in basal two-thirds, equal in width to the latter, the sides 

 convergent and nearly straight in apical third, the apex acutely ogival and 

 minutely, feebly notched ; disk with unimpressed series of rather large dis- 

 tant punctures, the scutellar impression large and distinct. Abdomen rather 

 finely, unevenly and closely punctured but strongly shining through the
