282 HEMIPTERA-HETEROPTERA. 
of the disc, the black markings in some specimens extending to the sides and apex (leaving only a trian- 
gular patch on the disc behind yellow) and in others entirely obsolete; the elytra with the base of the 
clavus, the base or outer part of the corium, and a large patch of variable extent at the apex of the 
membrane, and sometimes a transverse median fascia, fuscous or black, the clavus and corium in some 
specimens almost entirely infuscate (and the membrane also) and in others entirely ochreous ; the wings 
flavo-hyaline, the apex only sometimes narrowly infuscate; the antenne black ; the legs black or fuscous, 
the anterior and intermediate femora to a greater or less extent flavescent at the base, the intermediate 
and posterior pairs with a flavescent ring before the tip, the intermediate femora sometimes flavescent to 
near the apex. Head nearly as long as the pronotum, with a few widely scattered hairs only above and 
beneath, armed with two short spines or conical tubercles above; the eyes large and prominent in the 
male, smaller in the female; antenne with joint 3 greatly thickened in its basal half in the male. 
Pronotum with rather prominent, laterally projecting anterior angles, both lobes depressed down the 
middle, the posterior lobe with indications of two converging carine on the dise anteriorly, the lateral 
angles obtuse and somewhat tumid. Scutellum produced into a short tooth behind. Elytra extending 
far beyond the abdomen. Legs rather slender. Rostrum with joint 1 almost as long as the two others 
united. 
Length to apex of the elytra 13-133 millim. (¢ 9.) 
Hab. Panama, Bugaba, Volcan de Chiriqui, Caldera (Champion). 
This very variable species is not uncommon in Chiriqui, and amongst the twenty- 
seven examples examined four only have the dark median fascia on the elytra: three 
have the corium and clavus pale, except that in one of them (¢) the dark median 
fascia is present and crosses the corium. G. varians is very like the South-American 
G. fasciatus (Fabr.) (=gracilis, Burm.), a female specimen of which has been lent me 
by Dr. Aurivillius; but it differs from that species in having the head a little longer 
(both before and behind the eyes) and almost glabrous beneath, the antennze more 
slender, the under surface and pleura almost entirely pale, the wings not fasciate, &c. 
The colour of the legs and upper surface is very variable: the elytra are sometimes 
almost entirely infuscate, but in the pale examples the dark patch is always present 
at the apex of the membrane; the anterior and intermediate femora are sometimes 
flavescent, with the apex only dark, the hind pair, however, always have the base and 
a ring before the apex flavescent. The fasciate form resembles G. cingulatus, Stal 
(the type of which is before me); but it is much smaller and has more slender legs, the 
head is almost glabrous and not at all convex beneath (convex and densely pilose 
beneath in G. cingulatus), the wings are not fasciate, the spines on the head are 
shorter, &c. 
From G. flavidatus, Stél (the type of which has also been seen), it may be separated 
by the dark apex of the membrane. We figure four of the extreme forms.
