to the latter genus that Philenus does to Aphrophora; and if the former two are classed 
together, the latter should also be united. I believe that, in the face of the occasional 
inconstancy of the alar venation (as in Aphrophora grisea), this would be the best 
course ; but the genus Philenus has been so generally adopted that I do not care to 
discard it in the present state of our knowledge. 
1, Xenaphrophora montana, sp. n. (Tab. XII. fig. 10.) 
Fusco-brunnea, perobscure variegata, nitida ; vertice densius et rugosius punctato ; pronoto longitudine sesqui- 
latiori, distincte sed remotius punctato precipue ad medium, lined centrali levi fusci; scutello sparse 
punctato; tegminibus ad apicem angustatis, dense fortiusque punctatis, venis sat crassis nigro-fusco 
testaceoque variegatis. 
Fuscous-brown, shining, obscurely variegated with darker and lighter colour; metopidium fuscous in front, 
testaceous with dark lines on each side of the centre; vertex closely and somewhat rugosely punctured ; 
pronotum about half as broad again as long, not very closely punctured, with a broad smooth fuscous 
central line; tegmina fuscous, with some very obscure lighter markings, and with rather strong veins 
which are distinctly variegated with dark fuscous and testaceous ; the punctuation is strong and distinct, 
and continued to the apex of the tegmina; legs fusco-piceous ; underside testaceous. 
Long. 10-11 millim.; lat. 4 millim. 
Hab. GuateMaLa, Quiché Mountains, 7000-9000 feet (Champion). 
Two females. 
MICROSARGANE, gen. nov. 
Elongata, angusta, parallela ; capite magno, ante oculos producto, vertice rotundato, oculis magnis transversis, 
ocellis inter se et ab oculis fere «que distantibus; pronoto longitudine duplo latiori, basi emarginata; 
scutello sat magno, apice acute producto; tegminibus longis, parallelis; alis vena tertid interiori ante 
apicem furcaté aream apicalem sat magnam formante; pedibus teretibus, tibiis posticis spinis duabus sat 
robustis instructis ; sculptura subtilissima. 
Elongate, narrow, and parallel, very finely sculptured; head large; vertex considerably produced before the 
eyes, rounded at the apex; metopidium convex, nearly smooth; eyes large; ocelli almost as far distant 
from one another as from the eyes; rostrum moderately long, reaching the intermediate cox ; pronotum 
about twice as broad as long, strongly emarginate in the centre of the base; scutellum rather large, 
acutely produced at the apex; tegmina long, parallel; wings with the third vein from the exterior 
marginal vein forked at some distance from the apex and forming a large apical area; legs slender; 
posterior tibiee with two rather strong spines and a distinct crown of spines at the apex. 
This is a very distinct genus, and the species described below is much more diversely 
coloured than is usual in the subfamily *. Walker apparently includes it under 
Ptyelus, from which it certainly must be separated. 
1. Microsargane vittata, sp.n. (Tab. XII. fig. 11.) 
Brunnea vel griseo-brunnea, leviter pubescens ; lateribus verticis pronotique late testaceis, colore testaceo ad 
medium tegminum continuato, apicibus rufo, testaceo, nigroque variegatis, impressis; metopidio, corpore 
subtus, pedibusque testaceis, tarsis ad apicem fuscis. 
* In the Oxford Museum there is an insect labelled as having been found at Otaheite by the late Charles 
Darwin which must apparently be referred to this genus.
