the usual structure, as in Melanorhopala for instance; antennze 
(fig. 1, B) shaped much as in Hesperotingis, the third segment 
clavate, smallest at base and cylindrical toward apex. ‘Thorax 
as in Melanorhopala. Costal area of hemielytra uniseriate in the 
only known species; subcostal biseriate; discoidal extending beyond 
middle of hemielytra. In the short-winged form the hemielytra 
are rounded at apex, not divaricate, in the long-winged they are 
broadly rounded at apex and widely overlapping. Buccule 
closed anteriorly. Metasternal orifices distinct. 
A. grossocerata O. & D. 
Probably this specific name must stand for the present, although 
Oshanin in his catalogue of Palaearctic Hemiptera rejects such on 
grammatical grounds. The type specimen of this species is a 
short-winged male. The figure on page 246 of Osborn and Drake’s 
first paper is incorrect in certain important details. The antennif- 
erous tubercles are in reality constructed just as in related genera, 
and have no very striking similarity to an antennal segment. The 
third antennal segment is almost evenly clavate (fig. 1, B) and not 
fusiform as in Osborn and Drake’s drawing. The hemielytral 
areas are traceable, though stated in the description to be undif- 
ferentiated, but the main veins are scarcely elevated. The general 
form is more elongate and narrowed posteriorly than the drawing 
would indicate. In this species the rostrum reaches the middle 
coxe. 
Long-winged form.—Pronotum enlarged and convex as in re- 
lated genera. Hemielytra ample, extending considerably beyond 
apex of abdomen; costal margin slightly curved; sutural area with 
areoles grading larger inwardly and toward apex. Hemielytra 
distinctly more convex than in related genera, and habitus just 
as in the short-winged form except for structures affected by di- 
morphism. Length @ 3.4 mm. 
Described from a female specimen lacking the third and fourth 
antennal segments and otherwise somewhat mutilated, taken on 
Mt. Washington, N. H. (W. F. Fiske), and sent to me for examina- 
tion by Drake. The basal antennal segments are somewhat 
smaller than in the short-winged type specimen of the species, but 
this is no doubt due to individual variation as indicated by a short- 
winged male example intermediate in this regard but otherwise 
identical, submitted to me by de la Torre Bueno.
