Two females. They differ from the type, now before me, in having the anterior 
angles of the pronotum much more produced (instead of short, as in the type), 
and the connexival segments maculate at the sides, as well as at the base. The upper 
surface, the membrane excepted, is sparsely clothed (like the venter) with short, 
decumbent, ochreous hairs. The whole of the nervures of the elytra, the margins 
of the pronotum and several lines or vitta on the disc, and three longitudinal lines 
on the head, are of a sordid or reddish-ochreous colour ; the two irregular transverse 
reddish-ochreous marks on each of the connexival segments are in one specimen 
united, so as to enclose a marginal black spot, but in the other they are completely 
separated.

The three species of this genus are amongst the largest of the known Reduviids, and 
all of them are from Mexico. Meccus is scarcely separable from Conorrhinus, merely 
differing from it in the rather longer post-ocular portion of the head (exclusive of the 
neck), and the more prominent tubercles on the anterior lobe of the pronotum. The 
females (the only sex known to Stal when he described the genus) appear to be more 
thickly pilose, and more rugose, than the males, and to have the elytra relatively 
shorter than in Conorrhinus, extending to about the apex of the fifth segment.
