Tetraonyx batesi, Haag, Stett. ent. Zeit. 1879, p. 267’. 
Hab. Mexico, Tepansacualco, Oaxaca 1 (Sallé), Juquila (Boucard!, Sallé), Tehuantepec 
(Hége), Teapa in Tabasco (H. H. Smith); Guatemaua! (coll. F. Bates). 
We have received five specimens of 7. batest from Mexico, and there is a Guatemalan 
example of it in Mr. F. Bates’s collection. This insect is black above and beneath ; 
the elytra yellow or luteous-yellow, with eleven black spots of variable size arranged 
thus—five on each elytron, placed transversely, 2, 2 (sometimes coalescent), 1, and one 
at the suture below the scutellum. 
5. Tetraonyx bipartitus. (Tab. XVIII. fig. 8.) 
Tetraonyx bipartitus, Haag, Stett. ent. Zeit. 1879, p. 267'; Dugés, An. Mus. Michoacano, ii. 
p- 107 bis’*. 
Hab. Mexico, Mirador! (Sailé), Almolonga (Flohr?); Nicaragua, Chontales 
(Belt). 
We have received two specimens of this species—a female from Mirador and a male 
from Chontales. The latter is of very large size (21 millim. in length); it has the 
sixth ventral segment very deeply, semicircularly excised at the apex. Easily separable 
from our other species by the luteous or fulvous-yellow head and thorax and black 
elytra.

Hab. Mexico, Cordova (Sallé +). 
A small species, entirely black with the exception of the thorax, the latter flavo- 
testaceous (not sanguineous, as stated by Haag). The thorax is very strongly transverse 
and somewhat sharply carinate at the sides behind.
