CHALCOPLACIS.—PHEDRA. 189 
4, Chalcoplacis mexicanus. 
Ovately rounded, black, above dark bluish or greenish, the antenne and legs fulvous; head and thorax 
minutely granulate and finely punctured; elytra very closely punctate-striate. 
Length 1-1} line. 
Of moderately rounded and convex shape; the head in the male not perceptibly punctured, in the female 
finely punctate, in both sexes minutely granulate ; the epistome not separated from the face, its anterior 
edge moderately emarginate; mandibles large, partly fulvous ; antennx about half the length of the body, 
subfiliform, entirely fulvous ; thorax nearly three times as broad as long, scarcely widened at the middle, 
the sides rounded and slightly narrowed in front, the surface granulate like that of the head, and very 
finely and rather distantly punctured, the punctures only visible under a strong lens; scutellum smooth, 
scarcely broader than long ; elytra ovate, moderately convex, dark bluish, with closely approached rows 
of fine punctures, which become rather more obsolete posteriorly ; underside nearly black, the breast with 
a greenish gloss; legs dark fulvous, the apex of the posterior femora stained with piceous, . 
Hab. Mexico, Acapulco in Guerrero (Hége). 
Two specimens, apparently male and female, the former being at least one third 
smaller than the latter, and the female having the punctuation of the thorax and elytra 
very much more strongly marked; the shoulders are prominent, acute, and of a 
metallic greenish colour; the prosternum in the smaller example (male?) is broader 
than long, quadrate, and flat. In the strongly transverse thorax, its thickened flanks, 
and the ovately rounded general shape, the insect agrees with Chalcoplacis. 
PH.ZDRA (p. 111). 
The generic name Phedra having already been used three times in zoology, it has 
been changed by Lefévre [Cat. Eumolp. p. 166 (1885) ] to Phedrias. 
This author, in his diagnosis of the genus, gives the femora as unarmed; in 
P. maxima, Lefevre, however, they have a distinct tooth. 
Phedra maxima (p. 112). 
To the locality given, add :—Gvatemata, Coban in Vera Paz (Conradt). 
8. Phedra chapuisi. 
Above dull greenish, opaque, the antennm (the seventh and the apical two joints excepted), abdomen, and legs 
fulvous ; head, thorax, and elytra minutely granulate and finely punctured ; breast piceous. 
Length 13 line. . 
Hab. Panama, Bugaba (Champion). 
P. chapwisi seems to resemble P. rufipes, Chap., from Guiana, in coloration, so far as 
I can judge from the short diagnosis given by that author; P. rufipes, however, is 
described as “subnitida,” and with dark terminal joints to the antenne. In the 
Panama insect the entire upper surface is opaque, and of a greenish-leaden colour; the 
head has a few fine punctures (more numerous on the clypeus); the labrum and palpi, 
as well as the antenne, are fulvous, the latter having the seventh and the apical two
