2 PHYTOPHAGA.—SUPPLEMENT. 
An examination of Kirby’s type of O. childrent in the British Museum has proved 
to me that the Sonoran examples are conspecific with it. Kirby's description is, 
however, based upon an immature specimen in which the thorax (instead of being 
black, as in all the examples from Mexico before me) is fulvous with the disc obscure 
piceous, and the elytra are of a greenish colour. In the North-Mexican specimens the 
pattern of the elytra and other characters agree well with the type. The figure given 
by Kirby fairly represents the species, which may be known by the narrow black 
suture and the laterally widened transverse black band below the middle of the elytra. 
AULACOSCELIS (p. 1). 
Of this interesting genus, which up to the present time has included only three 
species, many others have since been received from Central America. Amongst the 
latter are two or three which may hereafter have to be removed to another genus, as 
they differ considerably from the typical forms in the structure of the antenne and in 
the shape of the head and thorax. 
These new species, however, possess all the more constant structural characters of 
Aulacoscelis, such as the more or less well-marked longitudinal grooves at the sides of 
the base of the thorax, and the rather flattened and depressed appearance of the elytra, 
and I accordingly refer them to it. 
Aulacoscelis melanocera (p. 1). 
To the locality given, add :—Mexico, Oaxaca (Hége), Northern Yucatan (Gawmer) ; 
GUATEMALA, Chacoj, Panzos (Champion); Costa Rica (Van Patten); Panama, Volcan 
de Chiriqui (Champion). 
Aulacoscelis candezei (p.1). (Tab. XXXV. fig. 7.) 
Black or piceous ; above fuscous, the elytra margined with fulvous. 
Var. a. Head, thorax, and elytra nearly black. | 
Var. 6. Above fulvous. 
Length 34 lines. 
To the locality given, add:—Mexico, Cerro de Plumas, Ventanas (Hége), San 
Miguel del Rio (Sallé). 
I have no doubt that I refer rightly the Mexican specimens before me to this 
species, and | am now enabled to give a more detailed description than the author has 
done in his short diagnosis. A. candezei seems to be a most variable insect in regard 
to colour, and it is very probable that other varieties exist; it greatly resembles A. hégei 
in shape, but may be at once separated from that species by having two cost on the 
elytra (instead of one) in both sexes. The thorax is of more transverse shape (agreeing 
w this respect with A. melanocera) and is either fuscous, black, or fulvous, with a few
