<5 . Antennse longer than the body, the third joint very minute. 

 Length l|-2 lines. 



Hah. Guatemala, Senahu, Sinanja {Champion). 



L. nigricornis is larger and of more flattened shape than L. dimidiaticomis, from 

 which it differs in th« finely punctured vertex in connection with the entirely black 

 antenme ; the fulvous band at the middle of the elytra is widened at the suture and 

 does not extend to the lateral margins. The antennae in the male insect extend beyond 

 the apex of the elytra; the third joint is smaller than the second, and the following 

 three joints are somewhat thickened and elongate. These characters will assist in the 

 recognition of L. nigricornis. 



7. Luperodes fulvo-fasciatus. 



Fulvous, the antennae, knees, tibiae, and tarsi black ; thorax finely punctured, obsoletely depressed at the sides ; 



elytra black, extremely finely punctured, a transverse band of regular shape at the middle, fulvous. 

 Length 2 lines. 



Hal. Mexico, Cordova (Salle). 



This insect resembles L. nigricornis in coloration, but is twice the size. The fulvous 

 elytral band of L. fulvo-fasciatus is broader than in that species, of very regular shape, 

 and extends quite to the lateral margins and very narrowly upwards along the suture 

 to the base ; the antenna? extend to two thirds of the length of the body and have their 

 third joint twice as long as the second. 



A single specimen. 



8. Luperodes humeralis. 



Ovate, widened posteriorly, fulvous; antenna and legs black; thorax impunctate; elytra very finely and 

 closely punctured, fulvous, a spot at the shoulder, and the lateral margin anteriorly, black. 



Length 2 lines. . . . 



Head fulvous, impunctate ; the clypeus not separated from the face ; labrum piceous ; antenna nearly as long 

 as the body, black, the third joint one half longer than the second; thorax twice as broad as long the 

 sides straight, the posterior margin rounded, the surface not visibly punctured, with a very obsolete 

 transverse depression on each side; scuteUum flavotis; elytra finely and closely punctured, fulvous, the 

 shoulders with a black spot, the lateral margins and the epipleurte at the base black; legs black; the 

 first joint of the posterior tarsi much longer than the f ollowing three joints united. 



Hah. Guatemala, San Geronimo, Panajachel (Champion). 



The black antenna? and legs and the humeral spot of the elytra (which extends 

 downwards along the lateral margin for a short distance) separate L. humeralis from 

 any of its congeners. 



9. Luperodes sallsei. 



Fulvous, the antenna, tibia?, and tarsi black; thorax and elytra very finely punctured, the latter with a spot 

 at the shoulder, another near the scutellum, the apical margin, and a subsutural spot near the apex, 

 black. 



Length 2 lines.
