94 PHYTOPHAGA.—SUPPLEMENT. 
antenne, which extend to the base of the thorax, have their terminal joints gradually 
thickened, and are black, with the basal two or three joints generally fulvous. The 
thorax is fulvous and opaque, strongly transverse, and (when viewed under a strong 
lens) closely covered with minute punctures, the extreme posterior margin having, as" 
usual, a deeper row of punctures, the margin itself being black. The elytra are dis- - 
tinctly narrowed at the apex, strongly punctate-striate, and blackish-green or bluish in 
colour; the striae commence at a little distance below the base and the punctures 
compdsing them gradually become smaller towards the apex; the interstices are 
extremely finely wrinkled and punctured, and the ninth is distinctly convex. The 
underside is black, with the exception of the prosternum, the latter being stained 
with fulvous. The legs are black, the tibie slightly stained with fulvous. 
M. panamensis differs therefore from M. gemellus in the black colour of its upper 
surface, in the absence of the spots on the thorax, and in the fulvous prosternum and 
almost black legs. The nearly black colour of the elytra, the punctuation of the thorax, 
and the fulvous prosternum separate the species from WV. bicolor (Fabr.). Suffrian, 
who described the last-named species at length, says nothing about the sculpture of 
the thorax; but he certainly would have mentioned the colour of the prosternum if it 
differed from that of the rest of the underside. The seven specimens obtained agree in 
all the above details. 
14. Monachus puncticollis, 
Black, the head, the base of the antenne, and the thorax dark fulvous; thorax deeply and closely punctured, 
opaque; elytra dark greenish, almost imperceptibly punctured except at the base. 
Length 1 line. 
9. Head finely rugose, entirely rufous; eyes large, with a narrow and short indentation at the middle; 
antennee very short, not extending beyond the middle of the thorax, black, the basal three joints fulvous ; 
thorax twice as broad as long, the sides but slightly narrowed in front, nearly straight, the surface of an 
opaque reddish-fulvous colour, and closely covered with deep punctures at the middle of the disc and near 
the base, the anterior portion and the sides much more finely punctured ; scutellum not longer than 
broad, black; elytra dark greenish, but slightly shining, the punctures only distinct at the base and very 
fine and gradually becoming obsolete posteriorly, the interstices minutely granulate and also sparingly 
punctured ; pygidium black, closely punctured; underside and legs black, shining ; prosternum fulvous, 
much broader than long. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
The single female specimen obtained differs from any other species from our region 
in the deeply and closely punctured thorax in connection with the green and scarcely 
punctured elytra; the thorax is very broad and proportionately long. J. cribricollis, 
Suffr., from Ega, seems to be closely allied, but has a much longer scutellum (nearly 
twice as long as broad), and the elytra black and shining.
