82 HEMIPTERA-HOMOPTERA. 
Four specimens. This insect appears to secrete a considerable amount of waxy 
material, which is more compact than in Cizius. An example from Bugaba is figured.

The species belonging to this genus are of small size. They have the upper portion 
of the frons produced at the sides into short ear-like processes, which, when viewed 
from above, look like two small blunt horns; the frons and clypeus together form an 
isosceles triangle, with the vertex of the head as the base; the pronotum is very short, 
and the scutellum large, with the carine not strongly marked; the tegmina, as a rule, 
are much widened behind, but in some species they are subparallel; the frontal ocellus 
is very distinct. |

This insect varies considerably in size and markings. In the male the last abdominal 
segment appears to be bisinuate, more or less produced in the middle, and the styles 
are rather large, but the characters are more pronounced in some specimens than in 
others. The examples from Atoyac and Fortin, all females, may prove to be specifically 
distinct. There is also in our collection an imperfect female, taken by Mr. Rogers at 
Irazu, Costa Rica, that comes very near B. tinealis. 
B. westwoodi, Stél, appears to be a variety of B. tinealis, in which the dark and 
light colour is more broken up behind. We figure a typical specimen from Teapa, 
and also one of the var. westwoodi from Atoyac. 
2. Bothriocera signoreti. (Tab. IX. figg. 13, 13 a.) 
Bothriocera signoreti, Stal, Stett. ent. Zeit. xxv. p. 50 (1864) *. 
Hab. Mexico!, Cuernavaca in Morelos and Amula in Guerrero (H. H. Smith), 
Atoyac in Vera Cruz (Schumann). 
A very distinct species, with regular and constant markings. It may easily be 
known from the preceding by having the hind margin of the tegmina always broadly 
black and opaque: in B. tznealis it is more or less hyaline. In the male the genital 
segment is bisinuate at the apex and produced into a sharp minute tooth in the 
centre, and the styles are long. We figure a specimen from Amula.
