50 PHYTOPHAGA.—SUPPLEMENT. 
1(a). Megascelis suturalis. 
Megascelis suturalis, Lac. Monogr. in Mém. Soe. Liége, iii. p. 258. 
Hab. Mexico !, Toxpam, Cordova, Playa Vicente (Sallé), Cerro de Plumas (Hoge), 
Teapa in Tabasco (H. H. Smith). 
This species was unfortunately overlooked by me in the earlier part of this work, 
and will find its place close to WM. dilecta. It differs from the latter in the elytra being 
rounded at the apex, and in the fuscous sutural band (instead of being widened poste- 
riorly) being widest anteriorly and gradually narrowed behind. The general colour of 
the upper surface of MM. suturalis isa pale green, with the exception of the more or 
less broad fuscous sutural stripe; this stripe is described by Lacordaire as “ nigricante,” 
but specimens with so dark a stripe I have not seen. 
A good many specimens have lately been received from Teapa ; these vary con- 
siderably in size, but only a little in colour. In all the head is strongly rugose and 
the suture narrowly fuscous; the sutural stripe, however, is not (as usual) widened 
anteriorly, but is of equal width throughout or slightly widened towards the apex. 
1 (s). Megascelis minuta. 
Narrowly elongate, pale testaceous, above with a metallic green tint; terminal joints of the antenne black ; 
head distinctly punctured ; thorax not longer than broad, closely punctured ; elytra sparingly pubescent, 
strongly punctured, the interstices transversely rugose. . 
Length 14 line. 
Head pale metallic green, distinctly and rather closely punctured, the epistome not separated from the face ; 
mandibles black; antenne two thirds the length of the body, black, the basal three or four joints testa- 
ceous; thorax not longer than broad, rather distinctly narrowed at the base, the sides rounded and 
widened, the surface with a shallow but distinct transverse groove across the disc, the latter closely 
impressed with distinct punctures which are a little larger than those on the head, the interspaces only 
very slightly rugose near the base; scutellum truncate at the apex, distinctly punctured; elytra narrowly 
parallel, pale fulvous with a more or less distinct metallic green gloss which is more intense at the 
shoulders, the latter prominent and acute, the surface strongly punctate-striate, the interstices trans- 
versely rugose and sparingly covered with short pubescence; underside pale piceous or testaceous; legs 
entirely testaceous. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
This small species is closely allied to WU. suturalis, Lac., but differs apparently in the 
very pale colour of the upper parts and in the sculpture of the head; the latter (instead 
of being closely rugose) is impressed with single punctures, the interspaces being smooth. 
M. minuta may be known from I. viridipallens, Clark, by the much smaller size and 
several other differences, which will be seen by a comparison of the respective descrip- 
tions. WM. gracilis, Lac., seems to be another close ally of MZ. minuta.
