146 PHYTOPHAGA.—SUPPLEMENT. 
obscure lateral marks flavous; elytra irregularly punctured, with two indistinct discoidal cost and a 
narrow sublateral one flavous, the disc with two, the sides with three, indistinct brown spots. 
Length 12-2 lines. 
Hab. Muxico, Oaxaca, La Parada (Sal/é). 
The sculpture of the elytra of P. sall@i would seem to place the insect in Suffrian’s 
sixth group, the nearest allied species being, apparently, P. cribellatus. From this 
latter P. sall@i differs in the colour of the underside and in several other particulars. 
The head is closely covered with brown punctures, but with a narrow margin round 
the eyes bright flavous ; the antenne do not extend to the middle of the body, and are 
black with the basal four or five joints fulvous. The thorax is strongly transverse in 
shape, and the sides are much deflexed, so that the lateral margins cannot be seen 
when the insect is viewed from above; these latter are somewhat prominent behind the 
middle but oblique towards the apex; the surface is crowded with brown punctures, 
which leave one central and two obscure lateral marks of the flavous ground-colour 
(these markings are very obscure and better seen without a lens). The scutellum is 
black or brown. The elytra are more strongly punctured than the thorax, and the 
punctuation for the most part is irregular; two raised longitudinal narrow flavous 
spaces are visible between the shoulder and the suture, and there is a similar costate 
space near the lateral margin; the interior of all the punctures is dark brown in colour, 
although the ground-colour may be described as flavous; and there are about five very 
obscure brown spots, of which three are placed along the sides and two on the disc. 
The pygidium is yellow, with its basal margin black; the underside is black (in some 
specimens of a dark brown colour), spotted with yellow at the sides of the abdominal 
segments ; the legs are dark fulvous, with the apex and base of the femora more or less 
flavous. 
The absence of well-defined longitudinal coste on the posterior portion of the elytra 
(these being present in so many species of Pachybrachys) will make P. sallei compa- 
ratively easy of recognition ; and the rusty-brown colour of the upper surface, interrupted 
by the obscure paler spots, the very closely punctured thorax, and the dark underside 
and fulvous legs will further assist in its determination. 
Female examples only have been received. 
Pachybrachys hepaticus (p. 71). 
To the localities given, add :—Mexico, Amula and Tepetlapa in Guerrero (ZH. H. 
Smith); Guatemaa, Las Mercedes, Cerro Zunil (Champion). 
P. hepaticus seems subject to so much variation in colour and in the pattern of the 
elytra that it is somewhat doubtful whether all the specimens from the above localities 
are really referable to it. Suffrian’s description of Melsheimer’s species does not agree 
with most of the Guatemalan examples, these being rather more robust and cylindrical,
