112 , HEMIPTERA-HOMOPTERA. 
Allied to the preceding, but of a pale testaceous colour, with the head pale, sometimes with darker markings, 
and with the pronotum broadly castaneous in front as well as at the apex; sometimes the apex is pale 
and there is a dark patch before it; the tegmina are hyaline, with a broad oblique patch at the apex, 
which is sometimes very distinct and sometimes only just indicated ; legs rufo-testaceous. 
Long. 64 millim.; lat. int. hum. 3 millim. 
Hab. Mexico, Xucumanatlan and Omilteme in Guerrero 7000 to 8000 feet 
(7, H. Smith); Guatemaua, Quiche Mountains 7000 to 9000 feet, Totonicapam 8500 
to 10,000 feet, San Gerdénimo 3000 feet (Champion). 
5. Phacusa dubia, sp. n. 
Brevior, pronoto testaceo, unicolori, vel antice nigro notato, tegminibus ad marginem fuscatis, venis pleramque 
nigris, crassioribus, areéque discoidali minimé; corpore subtus obscuriori; pedibus rufo-testaceis vel 
fusco-testaceis. 
Rather shorter than the preceding species, with the pronotum unicolorous or marked with a large black spot 
in front; the tegmina are infuscate towards the margin, with the veins for the most part thick and black 
and with the discoidal area very small; the legs and underside vary somewhat in colour. 
Long. 6 millim. ; lat. int. hum. 3 millim. 
Hab. Guatemaa, Cerro Zunil 4000 to 5000 feet (Champion); Panama, Volcan de 
Chiriqui 4000 to 6000 feet (Champion). 
I feel very doubtful with regard to one or two of these species, but with the present 
amount of material available it is hard to arrange them differently. St&l appears to 
have described P. pallescens and P. flavo-marginata on single specimens, and it is quite 
possible that when a large series is examined two or three of the species may be found 
to be not really distinct, as the differences appear to a certain degree to resemble those 
found in a large series of Acutalis fusconervosa, pale specimens of the latter species 
closely resembling P. pallescens, while some of the coloured specimens are very like 
P. variata, except that they are smaller. Asa rule, the formation of the single discoidal 
area of the tegmina is very distinct, but occasionally it is separated by an abnormal 
vein, so that the specimens in which this occurs might almost be referred to Euritea. 
6. Phacusa lineola. (Tab. VII. figg. 21, 21a.) 
Darnis lineola, Walk. List of Homopt. Ins., Suppl. p. 1467. 
Hab. Mexico (Glennie! ; Bilimek,in Mus. Vind.Cws.), Atoyac in Vera Cruz (Schumann). 
This species is narrower and more elongate than any of the preceding, and has the 
lines on the sides of the pronotum much more strongly impressed; it is, moreover, 
more closely and distinctly punctured, and therefore duller. The tegmina are almost 
entirely uncovered and are altogether hyaline, except for a distinct oblique dark band 
at the apex; the apical petiolate cell of the tegmina is very small; the colour appears 
to be green in life, but fades to testaceous in dry specimens. I have not much doubt 
in referring the species to Phacusa, although it might perhaps be made the type of a 
new genus. A specimen from Atoyac is figured.
