base, and usually two of the oblique veins beyond similarly coloured. The apical 
joint of the antenne, except at the base, and the tips of the tarsi are black. A 
specimen from Chiriqui is figured. —

Found in plenty in the “tierra caliente” of Chiriqui. Described from a single 
example. In this species the anterior margin of the pronotum and the antenne are 
sparsely pilose, and the discoidal area of the elytra is abruptly closed behind by a 
transverse oblique raised nervure. G. nigrinervis is extremely like G. trichoptera, Stal, 
also from Colombia; but it is smaller, and differs constantly from it in the angularly 
dilated pronotal margins. Both species have three or four oblique blackish nervures in 
the costal area of the elytra. A specimen from David is figured. 
3. Gargaphia panamensis, n. sp. (Tab. I. figg. 14; 14a, profile.) 
Moderately elongate ; ferrugineo-testaceous, the body black beneath, the margins of the pronotum and the 
elytra subhyaline; the antenne testaceous, with the basal and apical joints black ; the legs testaceous, 
with the tarsi and the greater part of the tibie infuscate; the margins of the pronotum and the costal 
margin of the elytra to about the middle very minutely denticulate. Head with three short slender 
frontal spines, meeting at the tip; antenne long and slender, joint 1 three times as long as 2 and nearly 
as long as 4, 2 very short. Pronotum with the membranous margins moderately wide, rounded in front 
and behind and slightly recurved, with three rows of small areole; hood rather small, oval, compressed, 
angularly projecting in front; the three carine feeble, foliaceous, the interspaces closely, finely punctate. 
Elytra moderately long, arcuately widened from the base, broadly rounded at the tip; discoidal area 
narrow, barely one-third the length of the elytra, closely reticulated; subcostal area as wide as the 
discoidal, closely reticulated ; costal area with four rows of areole at the middle, diminishing to three 
at the base, the areole, except towards the base, where they are small, moderately large and (ke those 
of the sutural area) subequal in size, 
Length 24, breadth 13 millim. 
Hab. Panama, Caldera in Chiriqui (Champion). 
One specimen. In this small species the rostral groove is interrupted between the 
meso- and metasternum by a prominent transverse carina, and the insect is, therefore, 
a true Gargaphia. ‘The anteriorly constricted pronotum makes the membranous 
margins appear much broader in front. It is prubable that fresh specimens have the 
pronotal margins ciliate. 
4, Gargaphia iridescens, n. sp. (Tab. Il. figg.* 1, 1 a.) 
Moderately elongate; body black, the integument yellowish-white, the elytra with the discoidal area slightly 
infuscate at the base and apex, the apical portion of the nervure limiting it externally fuscous, the costal 
area and the greater part of the sutural area hyaline and iridescent, the costal area with three or four of 
the transverse nervures in the basal half blackish and the other nervures pale; the antenne with joint 1 
black and 2 testaceous (the others broken off); the legs testaceous, with the tarsi blackish at the tip; the
