596 PHTTOPHAG-A. 



the longest, the five or six lower joints fulvous, the rest black ; thorax about one half broader than long, 

 the sides slightly rounded before the middle, nearly straight at the base, the angles distinct but not 

 prominent, the surface very minutely punctured, with (when seen in a certain light) two or three small 

 nearly obsolete depressions near the base ; scutellum black ; elytra closely covered with fine punctures 

 which are somewhat arranged in rows ; legs black, the extreme base of the four posterior tibiae, and the 

 anterior tibia entirely, fulvous ; the first joint of the posterior tarsi as long as the following two joints 

 together. 



Hab. Mexico 1 , Northern Sonora (Morrison). 



L. morrisoni differs from L. cyanellus, Lee, in the colour of the antennae and legs, 

 and in the more strongly punctured elytra. L. meraca, Say, is larger, and has the 

 antenna? and legs flavous, and the elytra with traces of longitudinal sulcations ; 

 L. longulus, Lee, is of more elongate shape, with the legs black, the general colour 

 dark bluish-black (not metallic blue or green), and the thorax entirely impunctate. 



I am much indebted to Dr. Horn for specimens of these North-American species, 

 with which I have been enabled to compare the present insect.

Hab. Noeth America, New Mexico 1 2 . — Mexico, Northern Sonora (Morrison). 



I refer two specimens from Northern Sonora to L. lecontii ; this species is compared 

 by Leconte with L, meraca, Say, with which it closely agrees, but differs in the less 

 acute and dentiform angles of the thorax and in the entirely fulvous legs. 1 must, 

 however, add that the Sonoran specimens though exhibiting these differences have the 

 thorax black and impunctate - r the elytra metallic green, and exceedingly finely and not 

 closely punctured, and with traces (in one specimen) of slight longitudinal costse ; and 

 the legs and antennae fulvous, each joint of the latter being slightly stained with 

 fuscous at the apex. 



3. Luperus rugosus. 



Black, above dark bluish- or greenish-black ; head, thorax, and elytra closely rugose-punctate. 



Length lg^-2 lines. 



Head strongly rugose at the vertex ; the frontal tubercles and carina distinct, the latter short ; antennae two 

 thirds the length of the body in the male, shorter in the female, black, the third joint about one half 

 longer than the second ; thorax about one half broader than long, the sides perfectly straight, the posterior 

 margin slightly rounded, the surface unevenly rugose and punctured, the middle of the disc sometimes 

 with some smooth. round spaces and a short ridge near the base; scutellum black, smooth; elytra strongly 

 and closely punctured, the interstices wrinkled throughout, the epipleurae continued below the middle; the 

 underside and the legs black, finely pubescent ; the tibiae mucronate, the posterior pair with a long spine ; 

 the first joint of the posterior tarsi as long as the following three joints united ; claws appendiculate ; the 

 anterior coxal cavities incomplete.
