284 PHYTOPHAGA.—SUPPLEMENT. 
Metachroma mexicana (p. 171). 
To the Mexican localities given, add:—Cuernavaca in Morelos (/6ge). 
The specimens obtained by Herr Hége all belong to the unspotted variety. 
7. Metachroma longicollis. 
Obscure neous, the basal joints of the antenne and the legs fulvous; head and thorax closely punctured, the 
latter scarce.y broader than long; elytra obscure fulvous with a strong neous gloss, rather strongly 
punctate-striate. 
Length 1 line. 
Of narrowly elongate shape; the head eneous, rather remotely punctured on the vertex, more closely on the 
clypeus, the latter not separated from the face, its lower margin very slightly concave, the labrum and 
palpi fulvous; antenne extending very little beyond the base of the elytra, black, the lower four joints 
fulvous; thorax but slightly broader than long, the sides rounded, slightly subangulate at the middle, the 
anterior angles not or scarcely produced, the surface rather closely and strongly punctured, a little more 
sparsely on the disc, the latter with a narrow longitudinal smooth space in the middle; elytra obscure 
fulvous with a metallic eneous gloss, without any basal depression, the punctures rather strong and very 
regularly placed, gradually diminishing towards the apex, the interstices flat and impunctate; underside 
eneous, coarsely punctured; legs fulvous, the femora with a slight seneous gloss. 
Hab. Mexico, San Juan Bautista in Tabasco (Hége); Guaremaua, San Gerdénimo 
(Champion). 
Of this very distinct but typical species only a single specimen was obtained by 
Herr Hoge, two others by Mr. Champion. These latter are rather smaller, and have 
the elytra of a more decided eneous colour. . 
8. Metachroma ornata. 
Black or piceous, the basal joints of the antenne and the legs fulvous; above fulvous, the head with one, the 
thorax with two black spots; elytra strongly punctate-striate, the apex nearly impunctate, the disc with 
an irregularly shaped subquadrate black patch. 
Length 13 line. 
Head rather closely and finely punctured, the vertex with a central black spot, the clypeus not separated from 
the face, finely rugose ; labrum fulvous ; eyes deeply notched; antenne black, the lower six joints fulvous ; 
thorax transverse, the sides strongly rounded, the surface scarcely perceptibly punctured, fulvous, a large 
transverse slightly sinuate black spot on either side; scutellum fulvous; elytra pale fulvous, deeply punc- 
tate-striate, the humeral interstice convex and extending obliquely to the sides, the other interstices flat. 
and impunctate, the disc with a large subquadrate black patch (commencing below the base and extending 
beyond the middle, and with all its margins concave, the lateral ones deeply so), which extends upwards 
along the suture to the scutellum, and laterally in a narrow stripe to the shoulders, and is interrupted 
in the middle on either side of the suture by a narrow stripe of the ground-colour, the sides with 
two small black spots placed close to the lateral margin—one below the shoulders, the other a little 
before the middle. 
Hub. Mexico, Tapachula in Chiapas (Hoge). 
In one specimen the thorax has four small spots instead of two large ones.
