72 PHYTOPHAGA.—SUPPLEMENT. 
at 
of being rounded at the middle) is rounded anteriorly and distinctly narrowed or con- 
stricted at the base; the median lobe of the posterior margin is not rounded, but 
straight; and the pubescence on the disc is very long. The elytra scarcely vary in 
punctuation from those of M. tomentosa, and the black portion does not extend to the 
lateral nor to the apical margin. The legs are obscure fulvous; the posterior femora 
are dilated into a distinct tooth near the apex; and the tarsi (as well as the antennz) 
are black. 
Megalostomis flavipennis (p. 31). 
To the locality given, add:—Panama (Boucard), Bugaba, Volcan de Chiriqui 
(Champion). 
In some of the Panama specimens the tibie and tarsi are flavous; in all, the elytra 
(instead of being flavous as in the type) are fulvous, and in one specimen there is a 
small black spot placed on the shoulders. 
7. Megalostomis punctatissima. (Tab. XXXVI. fig. 22.) 
Subcylindrical, convex, black, finely pubescent ; thorax extremely finely and closely punctured; elytra very 
closely but distinctly punctured, finely pubescent, fulvous, a spot on the shoulders, and the posterior two- 
thirds, bluish-black. 
Length 4 lines. 
Hab. Guaremata, San Gerdénimo (Champion). 
This species, of which we have received but a single specimen, at first sight might 
easily be mistaken for M. dimidiata, as the coloration is exactly similar; the differences 
are, however, as follows :—The thorax in UW. punctatissima is distinctly more narrowed 
in front and less transverse, and its punctuation (instead of being distinct as in M/. dimi- 
diata) is extremely close and fine, so as to be scarcely visible, and the colour is not 
black but bluish ; the elytra also have their dark portion with a distinct bluish gloss, 
and the punctuation is like that of the thorax and finer than in the allied species, and 
the fulvous colour of the anterior third is narrowed at the suture, the black portion 
extending upwards nearly to the scutellum; the head is punctured like the thorax ; 
and the antenne are black, with the third joint only fulvous. 
8. Megalostomis fulvipes. (Tab. XXXVI. fig. 21.) 
Subcylindrical, black, pubescent, the sides of the thorax and the legs fulvous; elytra rather strongly and 
closely punctured, a large subtriangular band at the shoulder, and a spot at the apex, fulvous. 
Length 3 lines. 
Head very finely and closely punctured, finely pubescent; the anterior margin of the clypeus semicircular; 
labrum black; eyes notched; antennz fuscous, the basal joint black, the following two joints fulvous 
thorax subcylindrical, extremely closely and finely punctured and pubescent, the sides slightly narrowed 
towards the base, fulvous, the rest of the surface black; elytra subcylindrical, strongly punctured and 
finely transversely rugose, black, the fulvous spot surrounding the shoulder and extending downwards
