264 PHYTOPHAGA.—SUPPLEMENT. 
In the shape of the thorax &c., this insect agrees with Hermeophaga, but it appa- 
rently has no spine on the anterior tibie. The form of the frontal tubercles and the 
colour of the tarsi are its most conspicuous characters. 
PLECTROTETRA (p. 284). 
Plectrotetra proxima (p. 286). 
The locality for this species is Zapote, Guatemala, and not Bugaba, Panama, as 
stated on p. 286. 
Plectrotetra guatemalensis (p. 288). 
To the locality given, add :—Mexico, Cuernavaca in Morelos (H. H. Smith). 
16. Plectrotetra multipunctata. 
Obscure piceous, pubescent, the head, thorax, and legs fulvous; thorax remotely punctured; elytra metallic 
greenish, strongly punctate-striate, the interstices closely and finely punctured. 
Var. Entirely pale testaceous. 
Length 14 line. 
Head with a few punctures, the vertex obscure piceous, the lower portion fulvous; the antenne extending 
very little beyond the base of the elytra, black, the basal joint fulvous, the third and fourth joints equal, 
the terminal joints slightly thickened ; thorax transverse, the sides rounded, slightly narrowed in front, 
the basal sulcus deep and sinuate, the surface remotely punctured and sparingly pubescent; elytra 
greenish, strongly punctate-striate, the interstices finely punctured throughout and clothed with greyish 
pubescence ; beneath piceous; the breast in front and the legs fulvous, pubescent; the posterior tibise with 
a distinct spine ; the claws obsoletely bifid. 
Hab. Mexico, Yolos, Yolotepec (Salié). 
This small species differs from its allies (P. hirsuta excepted) by the pubescence of 
the upper surface, and from all others of the genus by the closely punctured elytral 
interstices. 
17. Plectrotetra nigripennis, (Tab. XLI. fig. 22.) 
Broad and robust, fulvous, the antenne, tibie, and tarsi black; thorax without basal groove, strongly 
transverse, sparingly punctured ; elytra black, opaque, closely punctured, the interstices finely aciculate. 
Length 33 lines. 
3. Of broad, subdepressed shape ; the head impunctate, the eyes oblique, entire, the frontal elevations broad, 
not much raised, bounded behind by a transverse groove, the labrum flavous ; palpi slender; the antenne 
extending to about the middle of the elytra, black, the basal joint fulvous below, the third joint slightly 
longer than the fourth, the apical joints shorter, slightly tapering; thorax very strongly transverse, the 
sides rounded towards the base, the anterior angles dentiform, produced outwards, the posterior angles 
obsolete, the dise with a short longitudinal groove on each side at the base (the usual transverse sulcus 
quite obsolete), a round fovea near the anterior angles, and an obsolete median channel, 
sparingly and finely punctured at the sides and at the middle, reddish-fulvous ; scutellum broad, sub- 
triangular, fulvous; elytra black, opaque, with a feeble basal depression near the suture, the entire disc 
closely and rather strongly punctured, the punctures near the suture arranged somewhat in rows, the 
interstices finely aciculate ; underside and the femora and tibix fulvous, clothed with whitish pubescence ; 
the surface very
