APHETEA.—CLEPSYDRIUS. 95 
Acutalis, and Hypamastris; the formation of the tegmina, however, appears to be 
different from that of any other genus which I have examined. 
1. Aphetea inconspicua, sp.n. (Tab. VI. figg. 25, 25 a, ¢; 26,264, 2.) 
Brevis, lata, fusca vel fusco-brunnea; pronoto dense punctato, vitta obscura albida vel testacea mox ante apicem, 
apice obtuso, fusco vel fusco-testaceo; tegminibus intus hyalinis, extus brunneis, punctatis, testaceo- 
variegatis, venis distinctis brunneis ; pedibus nigris vel brunneis. 
‘A short, broad, inconspicuous species, with the pronotum fuscous or fuscous-brown, closely and distinctly 
punctured, not shining, with an obscure light band just before the apex, and the apex obtuse, unicolorous, 
or obscurely testaceous; tegmina internally hyaline, externally towards the base opaque, strongly 
punctured, brown, variegated with testaceous, veins distinct, brown; legs black or brownish. © 
Long. 3-33 millim.; lat. int. hum. 2-24 millim. 
Hab. GuatEMALA, Chacoj and Cahabon in Vera Paz (Champion). 
A female from Chacoj and a male from Cahabon; the latter is considerably smaller 
and narrower, and of a darker, more uniform colour, and it is possible that it may 
belong to a separate species. 
CLEPSYDRIUS, gen. nov. 
Sat brevis, robustus; capite magno, antice quadratim producto, ocellis distinctis, inter se ac ab oculis fere seque 
distantibus, his magnis, prominulis; pronoto gibboso, antice ampliato, humeris prominulis impressione 
forti longitudinali a metopidio separatis, pone medium fortiter constricto, utrinque fortissime impresso, 
lateribus sub impressionibus supra visis subtriangulariter dilatatis, deinde ampliato, lato, globoso, convexo, 
apice lato, truncato, trispinoso; tegminibus venis crassis, corio uné vena a basi procedente mox in aream 
ovalem extensd, deinde areis discoidalibus tribus irregularibus, apicalibus quinque instructo; alis areis 
apicalibus quatuor, secundé stylaté; pedibus posticis preelongis. 
Oblong; head large, produced in front, ocelli very distinct, situated on a line drawn through the centre of the 
eyes, a very little nearer to each other than to the eyes, which are large and prominent; pronotum convex 
and gibbous, very strongly impressed at the sides (if viewed from above it appears wide in front, with 
the shoulders obtusely prominent, and is then gradually narrowed above the impression in a straight line 
to behind the middle, where it is constricted, and then strongly widened into a convex and globose lobe, 
which at its widest is about as broad as the prominent shoulders), the apex truncate, and bearing three 
spines, of which the two side ones are slender, short, and slightly deflexed; the central spine is 
probably longer, but is broken in the type specimen; on either side of the constricted portion of the 
dorsum below the impressed portion there is a broad subtriangular prominence; corium with one vein 
proceeding from the base, which is dilated into an oval area at a little distance from the base, and is 
followed by three irregular discoidal and five apical areas, the extreme area occupying the whole apex, 
and being almost: semicircular, veins incrassate and more or less arcuate; clavus with only the external 
vein; wings with four apical arcas, the second plainly stylate ; posterior legs very long. 
This genus is extremely difficult to locate; in the formation of the pronotum it is 
closely related to Parantonaé, but in the venation of the tegmina it approaches very 
nearly to Hypamastris, and it must probably be placed near the latter genus. 
1. Clepsydrius constrictus, sp.n. (Tab. VII. figg. 1, 1 a-c.) 
Niger, nitidus, capite inequali, pronoto sat fortiter subrugosius punctato, lineé centrali levi per totum 
percurrente ; spinis apicalibus ad basin testaceis; pedibus anticis et intermediis testaceis, basi tibiarum
