A single female specimen from Durango seems to belong here. It is a little darker 
than the three females from Georgia and Texas before me (including Westwood’s type 
of M. pallidus), and has the scutellum more finely punctured. The insect cannot be 
associated with either of the forms of MM. stali, on account of the finely and simply 
granulated sides of the anterior lobe of the pronotum. The pronotum is more flattened 
behind than in MW. lepidus.

(antenna) *. 
g. Comparatively short, ochraceous or greenish, the basal half of the pronotum, a patch at the apex of the 
scutellum, and sometimes the base of the latter, the base of the corium, the spiculz on the head, and a 
patch on the outer side of the femora, black, fuscous, or brownish; the antenne varying in colour—in 
some specimens blackish or fuscous, in others with the apical joint only dark; the inner (covered) portion 
of the corium carmine; the head, the basal joints of the antenne above, the anterior half of the pronotum, 
the cox and femora, the two hinder tibie, and the outer edges of the corium and connexivum, thickly 
set with setiferous spicule, which are longer and more prominent on the pronotum than elsewhere, the 
rest of the surface set with smooth pallid granules, these forming a variegate pattern on the scutellum ; 
the basal half of the pronotum and the base of the scutellum coarsely and closely, the rest of the scutellum 
and the corium finely, punctured. Antenne stout, joint 4 oblong-ovate, a little longer than 2 and 3 
united, 3 slightly longer than 2. Pronotum with the lateral angles broad and distinctly raised, excised at 
the apex, the excision forming two short teeth ; the two dorsal carine prominent, subparallel, reaching the 
anterior lobe. Scutellum narrowing a little forwards, rounded at the apex, and with a smoota, prominent 
median carina, which becomes much stouter towards the base. Abdomen cordate, the connexivum wide, 
the first segment feebly subangularly dilated laterally at the apex. 
@. Broader, almost unicolorous, ochraceous or greenish, the scutellum usually with a transverse darker spet 
before the apex; the apical joint of the antenne ovate, about as long as joints 2 and 3 united; the 
connexivum broader and extending to a little beyond the scutellum. 
Length 64-7, breadth 23-34 millim. . 
Hab. Mexico, Atoyac in Vera Cruz, Teapa in Tabasco (H. H. Smith!); Guatemata, 
Chiacam, Coban, Senahu, and Tamahu in Vera Paz (Champion 1). 
Numerous examples from Vera Paz, two only from Mexico, all from the Atlantic 
slope. The males vary in colour, the dark apical patch sometimes extending forwards
