CHALCOPHANA. 229 
name of C. emarginata; the Guatemalan localities have therefore to be transferred to 
that insect. The locality Costa Rica (Van Patten) should be erased altogether. 
4 (a). Chalcophana emarginata. 
2. Fulvous, the seven outer joints of the antenne black; thorax sparingly punctured ; elytra with a metallic- 
green transverse band at the base and a round spot below the middle, coarsely punctured, the interstices 
strongly longitudinally costate, the apex deeply emarginate. 
Length 33 lines. 
Hab. Guatemata, near the city, Zapote (Champion). 
C. emarginata is the only species of the genus known to me in which the apex of 
the elytra shows a deep emargination, the sutural angle (as in C. guadricostata) being 
produced into a short tooth; this may or may not be a sexual peculiarity. The general 
system of coloration is that of C. ancora; but the transverse basal band of the elytra in 
the present insect is not so long, and its posterior margin is concave, while the posterior 
spot (instead of being elongate-triangular) is of a more rounded shape. The sculpture 
of the elytra is coarse and deep, and the coste are very strongly raised except near 
the suture. These characters will assist in the recognition of C. emarginata. 
4 (s). Chalcophana nigritarsis. 
Fulvous, the antenne (the first four joints excepted) and tarsi bluish-black ; thorax irregularly and subremotely 
punctured; elytra metallic green, the extreme lateral margins, the 4pex, and a transverse central band, 
much widened at the middle, fulvous, closely geminate-punctate. 
Length 22 lines. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Similar in its system of coloration to C. cincta and several allied species, but differing 
principally from these by the colour of the tarsi and by the elytral punctuation. The 
antenne extend to two-thirds the length of the body, and have their four basal joints 
fulvous. The thorax is twice as broad as long, scarcely narrowed in front, with rounded 
sides; the surface is irregularly punctured, more closely so at the sides than on the 
disc. The elytra have a slight but distinct post-basal depression and prominent 
shoulders; the punctuation is arranged in close double lines which become indistinct 
outwardly ; the fulvous band is lozenge-shaped across the suture and extremely narrow 
towards the sides, where it widens again slightly and is connected with the similarly- 
coloured lateral margin; the tarsi are metallic bluish-black. 
The single example obtained is a male. 
Chalcophana simplex (p. 162). 
To the locality given, add :—Mextco, Tapachula in Chiapas (Hége). 
The Mexican specimens obtained by Herr Hége during his second journey agree 
sufficiently well with C. simplex to refer them to that species; they have, however, the
