224 PHYTOPHAGA.—SUPPLEMENT. 
27. Colaspis subzenea. 
Obseure dark seneous or piceous, the antennw and legs flavous; thorax rather strongly and closely punctured, 
the sides obsoletely bisinuate at the middle; elytra strongly and closely punctured, the interstices sub- 
rugose and longitudinally costate. 
Length 2-23 lines. 
Hab. Guatemaua (mus. Stuttgart), near the city 5000 feet (Salvin). 
C. subenea is of a uniform dull fusco-eneous colour. It varies a little in the amount 
of the punctuation, the head and thorax, however, are generally rather closely and 
distinctly punctate; the lateral margin of the thorax is not dentate but obsoletely 
bisinuate; the elytra are almost rugosely punctured (owing to the interstices being 
cregularly raised on either side), and have the longitudinal interspaces broad and 
especially distinct near the apex, the interspaces costate, but not forming acute ridges. 
C. subenea is perhaps nearest allied to C. interstitialis, Lefévre, in regard to colour, but 
differs entirely in the shape of the thorax and in the elytral sculpture. 
28. Colaspis inconspicua. 
Obscure piceous or brownish-zneous; thorax more or less distinctly punctured, the sides dentate or subangulate 
below the middle; elytra opaque or slightly metallic, geminate-punctate-striate, the interstices longi- 
tudinally costate. 
Length 24-3 lines. 
Of rather elongate and convex shape; the head closely and somewhat rugosely punctured ; the antennz two- 
thirds the length of the body, the basal joints more or less fulvous, the others fuscous ; thorax twice as 
broad as long, narrowed in front, the sides narrowly margined, sinuate before and angulate or dentate 
below the middle, the surface rather more strongly and closely punctured at the sides than at the middle ; 
elytra with regular and deep rows of punctures arranged in pairs, the interstices strongly and regularly 
costate throughout (each elytron with eight costa); legs piceous or fulvous. 
Hab. Panama, Volcan de Chiriqui (Champion).—BraziL, San Paulo (coll. Jacoby). 
This species, of which about twenty examples were obtained in Chiriqui, may be 
known by its dull opaque colour: some specimens are nearly black, others are obscure 
brownish-eneous. The thorax varies in the amount and intensity of the punctuation, 
but the sides are always toothed below the middle; the elytra are regularly geminate- 
punctate-striate, and have the interstices costate. A single specimen from San Paulo 
in my collection does not differ in any particular from those from Chiriqui. C. inter- 
stitialis, Lefévre, from Brazil, is a closely allied species; it is, however, of a much more 
metallic and shining colour, and has the antenne and legs testaceous, the elytral coste 
much less strongly raised, and the lateral tooth of the thorax situated at (not below) 
the middle. Two specimens obtained by Mr. Champion differ from the others in having 
a fulvous head and thorax. 
29. Colaspis yucatana. 
Oblong, convex, dark violaceous, the labrum and antennxy fulvous; thorax sparingly punctured, the sides 
angulate just below the middle; elytra closely and deeply punctured at the sides, punctate-striate near 
the suture, the interstices convex at the apex. 
Length 2} lines.
