LUPERODES. 591 



which do not seem to differ to any marked degree from the Old- World forms ; twelve 

 are here described. 



1. Luperodes apicalis. 



Oblong ovate, slightly widened posteriorly, fulvous; antennae, tibiae, and tarsi black; thorax with two obsolete 

 depressions; elytra very finely and closely punctured, fulvous, the apical portion black. 



Length 2 lines. . . 



Head impunctate; the frontal tubercles distinct; the clypeus not separated from the face; palpi piceous; 

 antenna nearly as long as the body, the second joint short, the third one half longer, black, the basal joint 

 fulvous beneath; thorax twice as broad as long, the sides straight, the posterior margin rounded, the 

 surface very finely punctured, with an obsolete transverse depression on each side ; elytra slightly widened 

 towards the apex, the latter black, the basal two thirds fulvous, punctured like the thorax; the underside 

 and the femora fulvous, paler than above, the knees, tibiae, and tarsi black ; the first joint of the posterior 

 tarsi as long as half the tibia. 



Hab. Guatemala, Sinanja in Vera Paz (Champion). 



2. Luperodes melanocephalus. 



Broadly ovate, testaceous; the intermediate joints of the antennae, the head, and the breast black; thorax 

 impunctate ; elytra very minutely punctured, each with two spots at the base and two below the middle, 

 black. 

 Length 3 lines. , 



Head impunctate, black; palpi robust; antennae two thirds the length of the body, testaceous, the sixth ana 

 seventh joints and the apex of the terminal one, black, the third joint twice the length of the second the 

 other joints elongate, equal ; thorax more than twice as broad as long, the sides nearly straight, slightly 

 narrowed towards the apex, the anterior angles obliquely rounded, thickened, the posterior margin rounded, 

 slightly sinuate in the middle, the surface impunctate, very obsoletely depressed at the sides ; scutellum 

 triangular, testaceous ; elytra closely and finely punctured, obsoletely depressed near the middle, with an 

 elongate spot at the shoulder, a rounded one near the scutellum, and two others placed transversely below 

 the middle, black; legs testaceous, the posterior tibiae with a long spine; the first joint of the posterior 

 tarsi much longer than the following three joints united. 



Hab. Panama, Volcan de Chiriqui (Champion). 



There is only a single specimen before me of this comparatively large species ; in the 

 elytral pattern it somewhat resembles certain forms of Diabrotica. 



3. Luperodes biannularis. 



Ovate, convex, testaceous; the vertex of the head, the antenna, and the tibia, and tarsi black; thorax 

 narrowly transverse; elytra finely punctured, each with a broad transverse band at the apex and a ring- 

 shaped mark at the base, black. . . 



<j . Antennae longer than the body ; the third joint extremely small, shorter than the second joint. 



Length 1A line. . 



S Head impunctate at the vertex, the latter black; clypeus not separated from the face, forming a single 

 piece with the latter; eyes very large; antenna* longer than the body, black, the second joint small, 

 moniliform, the third only half the length of the preceding, the fourth joint extremely long, longer than 

 the fifth ; thorax transverse and short, more than twice as broad as long, the sides and the posterior 

 margin rounded, the surface very finely and irregularly punctured, testaceous; scutellum black; elytra 

 finely and closely punctured, the interspaces very finely semi-rugose ; the underside and the femora 

 testaceous, the tibise and tarsi blackish ; the first joint of the posterior tarsi half the length of the tibia. 



Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 

 Many specimens.
