588 PHTTOPHAGA. 



13. Malacorhinus godmani. 



Black, the head and thorax fulvous ; elytra extremely finely punctured, reddish-fulvous, a subquadrate spot at 

 the base, and a more transversely-shaped and smaller spot below the middle, black. 



cJ. Antennae robust, the third joint strongly curved and with its apex produoed ; elytra with an oblong 

 depression at the sides. 



Length 2 lines. 



Hab. Guatemala, Chiacam (Champion). 



The single male specimen obtained is similarly coloured to several of the preceding 

 species, but differs in the structure of the antennae from any of its congeners. These 

 organs have the joints (with the exception of the elongate first and the short second 

 one) robust, somewhat widened and triangularly shaped, and the third joint (which is 

 longer than the fourth) is strongly curved at its inner margin ; the three basal joints 

 are fulvous, the others black. The thorax is rather more transversely shaped than in 

 many of the allied species ; and the elytra have their basal spot broad and extending to 

 the suture but not to the lateral margin, and the posterior spot placed directly below 

 the lateral depression. 



14. Malacorhinus semifasciatus. 



Testaceous, the antennas, tibiae, and tarsi black ; head and thorax fulvous ; elytra testaceous, their apices 

 fulvous, a spot at the shoulder, another near the scutellum, a transverse band at the middle, and another 

 band below the latter, black. 



3. Elytra with a fovea at the middle of the sutural margin. 



Var. The bands and spots of the elytra more or less connected at the suture. 



Length 1| line. 



Head impunctate ; the frontal tubercles strongly developed ; antennae nearly as long as the body in the male, 

 shorter in the female, the third joint one half longer than the second but one half shorter than the fourth 

 joint ; thorax subquadrate, slightly narrowed at the base, the surface with some extremely fine punctures ; 

 elytra scarcely more distinctly punctured. 



Eab. Guatemala, Cubilguitz in Vera Paz (Champion). 



In well-marked specimens the two narrow transverse black bands of the elytra are 

 very distinct, and either connected with the scutellar spot or with each other ; in others 

 the posterior band is often nearly obsolete or entirely absent; the disc of the elytra is 

 generally testaceous, and the apices more or less fulvous. In the male insect the 

 antennae are furnished with rather robust and somewhat triangularly dilated joints; 

 the elytral foveae, which in the allied species are generally placed at the lateral margin, 

 are here transferred to the suture. Many specimens. 



15. Malacorhinus tricolor. 



Testaceous, the antennae, tibiae, and tarsi black, the head and thorax rufous ; elytra scarcely visibly punctured, 



testaceous, each with three transverse rufous bands, the first two margined with black. 

 6. Antennae with the terminal joints strongly serrate. 

 Length 3 lines. 



Head impunctate; the frontal tubercles transverse, narrow ; clypeus distinctly swollen, narrowly transverse ;
