behind the middle. It does not appear to me to be specifically 
distinct and in the absence of further material may, for the sake 
of exact reference, be called var. borealis nov. Holotype in M. C. Z 
collection. 
The example from the Delaware Water Gap, recently submitted 
to me by Barber, bears the MS. name Melanorhopala slossoni Heid. 
Hesperotingis fuscata sp. nov. 
Short-winged form.—Uniform dark fuscous, pronotum some- 
what paler, membrane of areoles opaque gray, main veins of hemi- 
elytra black. 
Anterior spines of head short, separated, but slightly curved. 
Antenne shorter and thicker than in the preceding, the third 
segment more evenly clavate, being subcylindrical only toward 
apex, not at base. Hood still more reduced, scarcely noticeable 
as distinct from the raised pronotal margin; paranota vertical, 
not applied to pronotal surface; carine more strongly elevated, 
as are the chief veins of the hemielytra; subcostal area biseriate 
but having a few extra areoles along the middle. Other characters 
as in the preceding. Form broadly ovate. Length 9 3.4 mm.; 
width 1.4 mm. 
Holotype: short-winged @, Golden, Colo. (W. J. Gerhard) in 
Barber’s collection. 
Easily distinguished from antennata by its uniform dark color, 
antennal shape, and vertical paranota. 
Alveotingis O. & D. 
This genus is notable for a very peculiar habitus arising from the 
extremely convex form and shining surface. In most of its 
characters it closely approaches Melanorhopala and Hesperotingis, 
while bearing a certain superficial resemblance to the Serenthiini 
although it of course lacks the pronotal and femoral structure 
characteristic of this tribe. It approaches the European Oncochila 
in having the hemielytral areas poorly defined, but differs widely 
in paranotal structure and in facies. The more important char- 
acters of Alveotingis may be stated as follows: form elongate 
oval, hemielytra very convex, their surface smooth and shining, 
without costate main veins, although the outlines of the areas are 
traceable. Head as in related genera, the antennal tubercles of
