Berecynthus, Stal, Stett. ent. Zeit. xxiii. p. 101 (1862); Ofv. Vet.-Ak. Forh. 1867, p. 527. 
The head has the central lobe generally much produced and prominent—a character, 
however, which appears to be variable, and will not bear the value which has hitherto 
been ascribed to it in generic diagnoses. The antenniferous tubercles are strongly 
spinous externally. 
One species only is known, which is common to Tropical America.

The specimen figured is a variety from Mexico, in which the central lobe of the head 
is barely prominent. ‘Taken alone it would have been considered a distinct species; 
but I fortunately possessed a series of specimens from Panama, which exhibited all 
gradations of this character, from typical forms to some in which the central lobe was 
almost as much abbreviated as in this Mexican specimen. 
PADAUS. 
Padeus, Stal, Stett. ent. Zeit. xxiii. p. 101 (1862) ; Ofv. Vet.-Ak. Férh. 1867, p. 528. 
This genus has many affinities with Euschistus ; the margins of the pronotum are not 
denticulated; and the anterior tibiz only are sulcated. ‘Two species are recorded as 
belonging to Padeus, both from Central America. | |
