590 PHYTOPHAGA. 



18. Malacorhinus reticulatus. (Tab. XXXIII. fig. 17, e .) 



Testaceous, the antennae (the basal and apical joints excepted), the tibiae, and tarsi black ; thorax fulvous, very 

 minutely punctured ; elytra very finely punctured, testaceous, the apical portion fulvous, the anterior part 

 divided by narrow black bands, the bands surrounding a central sutural, a small basal, and two lateral 

 testaceous spaces. 



c? . The elytra with a deep fovea at the middle of the lateral margin. 



Length 3 lines. 



Eab. Mexico, Cordova {SalU). 



M. reticulatus is at once distinguished amongst its allies by the curious pattern 

 of the elytra, the black portion of which resembles a network enclosing semiregular 

 patches of the ground-colour ; of these patches three smaller ones at the sides and base 

 respectively surround a larger sutural space at the middle of the disc. The antennae 

 have the first joint fulvous and the terminal three joints paler; the third joint is twice 

 the length of the second. A single specimen. 



19. Malacorhinus (?) centro-maculatus. 



Testaceous or fulvous, the antennas, tibiae, and tarsi black ; thorax and elytra opaque, the latter finely punc- 

 tured, each elytron with a small central black spot. 



Var. Elytra without black spots. 



Length 3 lines. 



Head impunctate ; the frontal tubercles distinct at the middle only, but contiguous with the sides ; antennae 

 nearly as long as the body, black, the apical three joints sometimes obscure fulvous, the second and third 

 joints small and nearly equal in length ; thorax nearly twice as broad as long, subquadrate, the sides 

 narrowly margined and rather deflexed, the surface somewhat flattened, not visibly punctured ; scutellum 

 broadly trigonate ; elytra opaque (like the rest of the upper surface), very finely and rather closely punc- 

 tured, each with a small black spot placed at the middle of the disc ; below and the femora fulvous, a 

 streak at the upper edge of the anterior femora, and the tibiae and tarsi, black ; tibiae with a small spine ; 

 the first joint of the posterior tarsi longer than the following three joints together; claws appendiculate. 



Eab. Mexico, Tepanistlahuaca (Salle); Guatemala, Capetillo (Champion). 



This species is provisionally placed in Malacorhinus; it differs from the other 

 members of the genus in the more transversely shaped and not posteriorly constricted 

 thorax, and in the longer metatarsus of the posterior legs. 



LUPEEODES. 



Luperodes, Motschulsky, Etud. ent. vii. p. 102 (1858). 



About twenty species of this genus have been described, all, with two exceptions, 

 inhabitants of the eastern portions of the globe. Luperodes is closely allied to Mono- 

 lepta and Luperus; from the latter it is separated by the first joint of the posterior 

 tarsi being much longer, the body more ovate and convex, and the thorax generally 

 with its posterior margin more or less rounded and the surface obsoletely trans- 

 versely depressed. One American species, L. kirschi, Har., has been described ; this, 

 however, seems to agree better with Luperus, to judge from a specimen in my 

 possession. We have nevertheless received a good many species from our country
