302 PHYTOPHAGA,.—SUPPLEMENT. 
verse, more than twice as broad as long, the anterior and posterior margins straight and parallel, the 
sides rounded at the middle, the anterior angles slightly thickened, the surface pale flavous, impunctate, 
with a shallow transverse depression on each side near the base ; scutellum black ; elytra slightly broader 
at the base than the thorax, metallic green, extremely finely and closely punctured, the interstices some- 
what finely aciculate ; the underside of the thorax and the legs pale flavous; the breast and abdomen 
black, shining. 
Hab. Panama, Volcan de Chiriqui (Champion). 
This species resembles P. longicornis in colour; but the antenne are shorter and 
entirely flavous; the elytral punctuation is much finer; the head, thorax, and legs are . 
lighter in colour ; and the general size is smaller. Three specimens. 
5 (a). Paleothona smithi. 
Black ; the head, the basal joints of the antenne, the thorax, and legs (the posterior femora excepted) fulvous ; 
elytra metallic green, closely and semi-regularly punctured. 
Length 17-13 line. 
Of rather convex shape; the head impunctate, fulvous, the frontal elevations flat, somewhat indistinct ; antenne 
rather stout, scarcely extending to the middle of the elytra, black, the basal five joints fulvous, the third 
and following joints of equal length; thorax one half broader than long, the sides evenly and rather 
strongly rounded, the surface with a few very minute punctures, and a depression in front of the 
scutellum; the latter black or piceous; elytra rather convex, metallic green, distinctly punctured in 
irregular rows, the shoulders prominent; legs fulvous, the posterior femora piceous ; the first joint of the 
posterior tarsi as long as the following joints united. 
Hab. Mexico, Xucumanatlan and Omilteme, both in Guerrero (H. H. Smith). 
Differing from all its congeners, P. longicornis excepted, by the somewhat convex 
shape of the elytra and their metallic green colour ; also by the rather robust antenne, 
which have their third and following joints equal. P. smithi is also allied to P. semi- 
fulva, but it may be known from that insect by the dark scutellum and underside. 
9, Paleothona nigricollis. 
Elongate, black; the head and thorax impunctate; elytra metallic greenish-blue, closely and strongly punc- 
tured. 
Length 12 line. 
Hab. GuateMata, Calderas on the slope of the Volcan de Fuego 7000 feet (Cham- 
pion). 
A single specimen. This insect differs from any of its allies by the black head, 
thorax, antenne, and legs in connection with the strongly and evenly punctured elytra; 
the antenne are slender and elongate, the third and fourth joints equal; the thorax 
has a deep fovea in the middle at the base; the elytra have no basal elevation, and are 
of a metallic greenish colour, the punctuation being distinct to the apex. 
10, Paleothona viridis, 
Black; the basal three joints of the antenne, and the tibie more or less, fulvous ; thorax greenish-black, 
minutely punctured ; elytra metallic green, closely punctured and finely rugose. 
Length 1 line.
