26 _HEMIPTERA-HOMOPTERA. 
‘In the type-specimen the dorsal prominences are very little elevated: it is possible 
that the specimens from Atoyac, in which they are much more elevated, may belong to 
a different species; if viewed from above, however, they are almost identical, and they 
can hardly be separated until more material is discovered ; the difference is not sexual. 
We figure a specimen from El Tumbador. 
3. Hypsoprora anatina, sp. n. (Tab. II. figg. 16, 16 a.) 
Fusco-ferruginea, plus minusve albido-vestita; pronoto scabro, dense sat fortiter punctato, antice in pro- 
cessum longum erectum, in medio externe rotundatim dilatato, deinde angustato, apice recurvo, extenso, 
carina centrali leviter spinosé, protuberantiis dorsalibus nullis; tegminibus apicem prothoracis haud 
superantibus, ferrugineis, opacis, ad basin punctatis ; pedibus rufis vel ferrugineis. 
An elongate and rather slender species, fusco-ferruginous, more or less distinctly clothed with a fugitive 
whitish secretion ; pronotum scabrous, thickly and distinctly punctured, produced in front into a long 
erect process, which i is strongly sinuate externally and dilated in the middle, and then rounded and slightly 
recurved before the apex, presenting the appearance of the outline of a duck’s head; in some cases, how- 
ever, the sinuation appears to be not nearly so marked, and the sides are subparallel; the distance from 
the front edge of the metopidium to the apex of the process is about equal to the distance from the same 
to the apex of the tegmina; there are no dorsal protuberances ; the tegmina are opaque and ferruginous, 
and the legs reddish.

This species is of about the same size as the preceding ; it has the apex of the short 
pronotal process shaped much as in Philya, but in other respects is more closely 
related to. Hypsoprora; it may, perhaps, form the type of a separate genus. An 
example from the Volcan de Chiriqui is figured.

This genus contains upwards of twenty species, which are all from Central or Tropical 
South America: the majority, apparently, inhabit Brazil. They are among the most 
extraordinary of the Membracide, and, in fact, there are few insects which assume 
more curious forms; in some cases, at all events, these forms are protective, for, when
