TOLANIA.—GARGAROPSIS. _ 167 
in the genus, but in the present species the apical areas are for the most part narrower ; the examples in 
our collection vary with regard to the presence or absence of pronotal horns. 
Long. 7 millim.; lat. int. hum. 3 millim. 
Hab. Guatemata, Sinanja and Cubilguitz in Vera Paz (Champion); Panama, Bugaba, 
Tolé, San Miguel in the Pearl Islands (Champion). 
Although this insect appears to be distinct from 7. opponens, yet I have separated it 
with great hesitation, owing to the extreme variability of the specimens of the genus 
which I have hitherto seen. The character, however, of the scutellum, which is a 
prominent feature in the genus, seems to be constant. 
GARGAROPSIS, gen. nov. 
Brevis, oblonga sat lata, capite longitudine paullo latiore, ocellis indistinctis, inter se quam ab oculis remotiori- 
bus; pronoto lato, mox ante basin obtuse angulato latissimo, humeris rotundatis, sine cornibus vel 
processu postico, basi supra scutellum truncata, vix sinuaté ; scutello magno, equilatero-triangulari, apice 
producto acuto, mox post medium linea semicirculari impresso ; tegminibus totis intectis, hyalinis, vitreis, 
nitidis, remote fortiter punctatis, nervis corii indistinctis, ad medium evanescentibus, corio areis apicalibus 
quatuor, discoidalibus nullis vel vix indicatis, alis areis apicalibus tribus ; pedibus posticis longis, robustis, 
tibiis externe utrinque distincte serratulis, setosis; pedibus anticis et intermediis brevioribus fere sim- 
plicibus. 
Oblong and rather broad, gently narrowed behind; ocelli indistinct, situated on a line drawn just between the 
centre of the eyes, to which they are closer than to one another ; pronotum in front of about the breadth — 
of the head, gradually widened towards the base, obliquely angled a little before the base and there 
broadest, the shoulders rounded; horns and posterior process entirely absent ; scutellum large, with its 
three sides about equal, acute at the apex; tegmina entirely uncovered, large, vitreous, with coarse 
remote punctuation, which is stronger on the clavus, corium with the radial and ulnar veins marked 
but indistinct, and with four apical areas, clavus large with the veins more distinct; wings with three 
apical areas, and with the reflexed portion (answering to clavus) very large and furnished with two large 
thick veins, which cut one another in the centre; posterior legs long and stout, tibie rather strongly 
serratulate on their outer margins, anterior and intermediate pairs rather short and simple. 
This is one of the puzzling genera which appear to be rightly placed at the end of 
the Centrotine, and which, on the other hand, scarcely appear to be true Membracide. 
The present genus is very distinct from any other described, and does not appear 
to have any striking affinities. Very little, however, is known as yet about these 
transitional genera, as they appear to have been found very rarely, and one or two 
specimens at a time; they can therefore be only located provisionally at present. The 
position of the ocelli and the simple vertex of the head, as well as the formation of the 
tegmina, separate Gargaropsis very widely from Tropidaspis and Endoiastus. In: 
general facies it resembles a broad species of Gargara, though the resemblance is, of 
course, entirely superficial.
