- GYNANDROPHTHALMA.—MEGALOSTOMIS. 69 
Two specimens, one of which is nearly double the size of the other, were obtained 
by Mr. Champion. This species differs from all others described in this work in the 
pattern of the elytra. | 
Gynandrophthalma leucognatha (p. 29). 
To the locality Mexico, add:—Pachuca in Hidalgo, Juquila (Hége), Guanajuato, La 
Parada, Oaxaca (Sallé). 
Although none of the specimens received from the above localities quite agree with 
Lacordaire’s description of G. leucognatha, I do not think it advisable to describe them 
as new, taking into consideration the great variability of the species of the present 
family ; and I am not even sure whether these Mexican specimens may not equally 
well be varieties of G. quadripartita, this latter species having been described by 
Lacordaire from one female specimen only. In the examples from the above-mentioned 
localities, the head and thorax agree with Lacordaire’s description of G. leucognatha, 
but the elytra differ in having black (instead of bluish) markings; the sutural band is 
very narrow and of equal width (not wider anteriorly); there is only a small spot 
(instead of a large triangular one) at the middle of each elytron, this spot not being 
connected with the black lateral margin; the basal margin and a spot on each shoulder 
are black ; and the punctuation is very strong and continued to the apex. The colour of 
the legs agrees with the description of that author. In one specimen the posterior spot 
of the elytra is subquadrate and in the shape of a transverse band, and the sutural band 
is widened posteriorly ; another has the entire posterior half of the elytra black. 
It will be seen, therefore, that in a species so variable no reliance can be placed on 
colour or pattern, and that differences in this respect cannot be considered specific. 
MEGALOSTOMIS (p. 29). 
Megalostomis pyropyga (p. 30). 
To the localities given, add :—Muexico, Ventanas (Forrer), Oaxaca, Capulalpam, Vera 
Cruz, Etla, Cuernavaca, Puebla, Tehuantepec (Sallé), Matamoros Izucar, Huetamo in 
Michoacan, Guadalajara in Jalisco, Chilpancingo in Guerrero, Acapulco (Hége) ; 
SatvaDor (Sallé) ; Nicaracua, Chontales (Belt). 
Many specimens obtained by Herr Hége. This species is distinguished by the 
metallic cupreous anterior margin of the thorax, as well as by the similarly-coloured 
apical spot of the elytra, although this latter is sometimes very obscure and even 
absent. 
(a). Megalostomis metallica. (Tab. XXXVI. fig. 19.) 
Black, densely pubescent below ; above metallic purplish or greenish ; thorax sparingly and finely punctured 
elytra more closely and distinctly punctate, the basal and sutural margins metallic green. 
Length 3 lines.
