462 PHYTOPHAGA. 



is square-shaped, not narrowed at the base, with a shallow longitudinal groove and two 

 anterior obsolete elevations ; this, as well as the sculpture and colour of the elytra, is 

 as described by Harold. 



6. Physimerus pygmaeus. 



Dark brown or ferruginous, clothed with ashy pubescence; thorax narrowed at the base; elytra strongly 

 punctate-striate, a small spot near the base, and a larger one below the middle, denuded of hairs. 



Length 1 line. 



Head scarcely longer than broad, the vertex finely rugose-punctate ; eyes large, the intermediate space clothed 

 with whitish pubescence ; palpi filiform ; antennae as long as half the body, the terminal joints slightly 

 thickened, the third joint longer than the fourth, fulvous, the seventh and eighth joints often darker; 

 thorax very nearly square-shaped, distinctly narrowed at the base, the surface obsoletely transversely 

 depressed near the basal margin, densely clothed with yellowish or whitish hairs ; elytra closely and 

 distinctly punctate-striate, all the interstices slightly longitudinally costate, the ground-colour dark 

 brown, clothed with ashy grey or whitish pubescence, which is absent below the base and below the 

 middle, forming a small and a larger brownish spot; legs fulvous. 



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



Many examples. This very small species may be known by the thorax being distinctly 

 narrowed near the base ; the slightly but distinctly costate interstices of the elytra 

 (which have the basal portion scarcely more prominent than the rest of their surface) ; 

 and by the two spots on each elytron, which, in specimens in good condition, may be 

 seen without a lens. P. mimulus, Harold, seems to be a closely allied species, but 

 differs in the shape of the thorax and its two small elevations, in the distinctly raised 

 basal portion of the elytra, and in the markings of the latter. 



On herbage, in company with many other species of this group, about the margins of 

 newly made coffee plantations on the slope of the Volcan de Chiriqui at the beginning 

 of the rainy season (Champion). 



7. Physimerus zapotensis. 



Fulvous ; head and thorax granulate-punctate ; elytra black, clothed with yellow pubescence, scarcely depressed 

 below the base, distinctly punctate anteriorly, the apical portions nearly impunctate. 



Var. a. Elytra dark fulvous. 



Var. b. Thorax and elytra black. 



Length 1 line. 



Head closely and finely granulate (only visible with a strong lens), the frontal tubercles scarcely prominent, 

 the carina very short ; palpi filiform ; antennas scarcely half the length of the body in the male, shorter 

 in the female, entirely fulvous, all the joints short, the terminal ones gradually incrassate ; thorax scarcely 

 longer than broad, the sides slightly narrowed at the base, the disc with an obsolete longitudinal depression 

 near the anterior margin, the surface punctured like the head, and clothed with yellow pubescence ; elytra 

 with a very slight depression below the base, the punctuation well marked anteriorly but entirely absent 

 below the middle, the disc sparingly pubescent like the thorax ; legs entirely fulvous. 



Eab. Guatemala, Zapote (Champion). 



This seems to be a variable little species ; it may be known by the small size, the 

 fulvous antennse and legs, and the very obsolete elytral depression. P. obscurus, Clark, 

 is larger, and differs in the colour of the legs and antenna?.
