PSEUDOGONA. 391 



the eyes as well as the frontal tubercles being small; the reverse is the case in 

 Pseudogona. 



1. Pseudogona panamensis. 



IMvous or flavous; head, intermediate joints of the antennae, the tibise, and breast, black; thorax fulvous, 

 impunctate ; elytra testaceous, a transverse band at the base, another at the middle, and a third below the 

 latter, black. 



Var. a. The two anterior bands of the elytra partly joined, including two testaceous spots. 



Var. b. Smaller and narrower, with an additional spot at the apex; antennae black. 



Length l|-2§ lines. 



Head with a deep fovea on the vertex, black ; palpi fulvous ; antennae less than half the length of the body, 

 the third joint distinctly longer than the fourth, the four lower joints obscure fulvous, the following four 

 black, the three terminal ones pale testaceous ; thorax not more than twice as broad as long, rather 

 convex, the angles but little produced, the anterior ones slightly thickened, the surface shining, fulvous, 

 impunctate ; scutellum black ; elytra very finely punctured, the punctuation arranged in close indistinct 

 rows, the two anterior bands connected at the suture, and in the variety near the lateral margin as well, 

 so as to surround two flavous spots, the posterior band deeply concave at its posterior margin and extending 

 across the suture. 



Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 



Oxygona sexnotata, Clark, bears a most extraordinary resemblance to the present 

 species in regard to the coloration of its elytra, and can, in fact, scarcely be distinguished 

 in this respect ; but in Clark's species the thorax is much more transverse and typical 

 of the genus, and the elytra are less distinctly punctured, the insect is also larger and 

 more robust, and the entire underside is flavous. I have nearly a dozen specimens 

 before me which agree in all the principal characters. In the variety above noticed the 

 bands are separated and narrower, and there is an additional spot at the extreme apex, 

 but intermediate degrees of coloration prove the species to be a rather variable one. 



2. Pseudogona chiriquensis. (Tab. XXII. fig. 22.) 



JFlavous ; head, the tibise, and the breast black ; thorax fulvous, impunctate ; elytra obscure testaceous, opaque, 

 extremely finely punctured, two short longitudinal stripes at the sides of each elytron, and two others at 

 the sutural margin, at the base and below the middle black. 



Length 2 lines. 



Head impunctate ; the frontal tubercles transversely oblique and obsolete ; carina distinct, widened in front ; 

 antennae long, black, the seven lower joints black, the following two fulvous (the rest wanting) ; thorax 

 about one half broader than long, subquadrate, rather convex, the posterior angles acute and slightly 

 produced, surface shining, fulvous, impunctate ; scutellum black ; elytra finely and closely punctured, 

 opaque, testaceous, a humeral longitudinal stripe extending nearly to the middle of the elytra, to the inner 

 side of which another very narrow line is attached, a stripe at the suture of equal length, and three other 

 shorter spots below the middle, placed in the same way, black; underside and the femora flavous, the 

 breast, tibiae, and tarsi black. 



Hab. Panama, Volcan de Chiriqui (Champion). One specimen. 



This species cannot be considered a variety of P. panamensis, on account of the absence 

 of the fovea on the vertex and the different pattern of the elytra, which are not shining, 

 but opaque.
