PALZOTHONA. 303 
Elongate, slightly widened posteriorly; the head broad, impunctate, very finely granulate, the frontal 
tubercles small; antenne two-thirds the length of the body, black, the basal three joints fulvous, the 
third joint only one half longer than the second, and much thinner than it, the fourth longer than the 
third ; thorax short, transverse, the sides slightly rounded, the anterior and posterior margins straight, 
the latter with a depression in front of the scutellum, the surface minutely granulate and punctured, 
greenish-black, not very shining ; scutellum greenish-black, pointed behind ; elytra metallic green, closely 
and rather strongly punctured, the interstices finely rugose ; below and the femora blackish; the knees 
and the tibie and tarsi more or less fulvous. 
Hab. Panama, Volcan de Chiriqui 8000 feet (Champion). 
Quite distinct from most of its congeners by the system of coloration and sculpture ; 
and from P. nigricollis by the finely punctured thorax and the rugose elytral interstices. 
The antenne are shorter in the female than in the male. Found in some numbers by 
Mr. Champion, in a bamboo-thicket on the slope of the Volcan de Chiriqui at a high 
elevation. 
11. Paleothona godmani. 
Black ; the antenne long and slender (¢); the head and thorax impunctate ; elytra metallic blue or greenish, 
finely and semi-regularly punctured ; legs black, the tarsi sometimes obscure fulvous. 
Length 1-14 line. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith) ; GuateMata, Chiacam in Vera Paz 
(Champion). | 
Of elongate, posteriorly slightly widened, shape ; the antenne black, with the third 
joint only a little longer than the second, the fourth twice the length of the third, and 
the other joints equal in length; the thorax rather convex, about one half broader 
than long, entirely impunctate, black, very shining ; the elytra metallic blue, finely 
punctured, the punctures remotely placed and arranged in semi-regular rows. This 
species is principally distinguished amongst its allies by the black head and thorax. 
The female is considerably larger than the male, and has much shorter antenne. 
P. godmani resembles P. nigricollis in colour, but it is much smaller and has the elytra 
finely (instead of strongly and rugosely) punctured. 
12. Palzothona dilaticornis. 
Fulvous ; antenne robust; head and thorax impunctate ; scutellum piceous ; elytra metallic green, strongly 
and closely punctured. 
Length 13 line. . 
Head rather broad, fulvous, impunctate, the frontal elevations strongly raised, subquadrate; antenne more 
than two-thirds the length of the body, entirely fulvous, the joints slightly dilated, the third and fourth 
triangularly widened, nearly equal, the following joints more elongate; thorax rather convex, one half 
broader than long, the sides evenly rounded, the angles not prominent, the surface impunctate, fulvous; 
elytra much wider at the base than the thorax, metallic green, the punctures strong and placed in close 
rows, less distinct at the apex ; underside and legs fulvous, the breast and abdomen slightly stained with 
fuscous at the sides ; the first joint of the posterior tarsi as long as the following joints together. 
Hab. Mexico, Jalapa (Hége).
