334 PHYTOPHAGA.—SUPPLEMENT. 
1. Agelastica viridis. 
Fulvous, the antenne piceous; thorax subquadrate, shining, impunctate ; scutellum black; elytra metallic 
green, finely and closely punctured, the interstices here and there minutely wrinkled. 
Length 2 lines. . 
Of elongate, parallel shape; the head impunctate, fulvous, the vertex with a faint metallic gloss, and a more 
or less distinct dark central spot, the frontal elevations narrowly oblique ;. the clypeus in the shape of a 
triangular ridge; the palpi slender, piceous; the antenne rather widely separated at their point of 
insertion, scarcely extending to the middle of the elytra, piceous, the lower three or four joints fulvous, 
the third joint one-half longer than the second, the following joints slightly longer than the third and 
nearly equal ; thorax about one-half broader than long, rather convex, the sides slightly constricted at the 
base and rounded before the middle, the anterior angles in the shape of a small tubercle, and furnished 
with a single seta, the surface shining, impunctate, fulvous; elytra a little wider at the base than the 
thorax, with a scarcely perceptible post-basal depression, rather convex and parallel, metallic green, very 
closely and finely punctured, the interstices minutely granulate and transversely wrinkled, the epipleure 
distinct. nearly to the apex; underside and legs fulvous, the breast metallic greenish at the sides; all 
the tibise mucronate; the prosternum not visible between the coxe. 
Hab. Mexico, Chilpancingo and Acapulco, both in Guerrero (Hége). 
-PSEUDODIABROTICA. (To precede the genus Microbrotica, p. 569.) 
Elongate; antenne long and slender; the thorax quadrate, with two oblique depressions ; elytra narrow, 
parallel, irregularly punctured, their epipleure broad anteriorly and extending below the middle ; legs 
very long and slender: the intermediate and posterior tibize mucronate; the first joint of the posterior 
tarsi as long as the following joints together ; claws bifid ; anterior coxal cavities open. 
This genus is proposed for a single species from Western Mexico. Pseudodiabrotica 
possesses nearly all the structural characters of Diabrotica, but is narrower and more 
slender. The legs are more elongate than is generally the case in Diabrotica, and the 
first joint of the posterior tarsi is much longer than in that genus. The male is further 
distinguished by the curious excavation at the apex of the elytra. 
1. Pseudodiabrotica metallica, (Tab. XLIII. fig. 16, ¢.) 
Black, above metallic green; head and thorax impunctate; elytra finely punctured, the interstices here and 
there transversely wrinkled. 
¢. Elytra with a deep longitudinal excavation before the apex, and the surface in front of this swollen, the 
apex itself pointed. 
Length 2-24 lines. 
¢. Head impunctate, the frontal elevations small and indistinct, the clypeus with a strongly raised central 
ridge extending between the point of insertion of the antenne ; the penultimate joint of the palpi incras- 
sate, the apical joint acutely pointed ; antenne black, extending to the middle of the elytra, all the joints 
(with the exception of the second) long and slender, and of nearly equal length ; thorax slightly broader 
than long, the sides coverging towards the base, the anterior angles furnished with a small tubercle and a 
single seta, the surface rather flat, metallic green, impunctate, and with a deep oblique fovea on each side 
the anterior and posterior margins straight; scutellum black; elytra narrowed posteriorly, wider at the 
base than the thorax, the shoulders scarcely prominent but distinct, the surface metallic green, finely and 
closely punctured in irregular rows, the interstices minutely granulate, the apex with a deep longitudinal 
excavation, and the surface in front of this much swollen; legs black, slender, elongate. 
Hab. Muxico, Omilteme and Chilpancingo, both in Guerrero (H. H. Smith). 
In the female the elytra are devoid of the apical excavation.
