(Agrammodes costatus n. sp.) 
From examination of the type of Agrammodes costatus Uhler 
and numerous other specimens I have no doubt that the species 
is a brachypterous Piesma. It possesses all essential characters 
of the genus including the divided discoidal area and peculiar 
thoracic cavities described further on; Uhler himself mentions 
“the characteristic head of Presma.” 
Uhler compares his species to Agramma and if we may judge 
from his selection of a generic name was much impressed by the 
similarities. Van Duzee places* Uhler’s genus and species in 
the Serenthiini, the tribe of the Tingidz to which Agramma—= 
Serentlia belongs. However one of the principal characters of 
that tribe is that the lateral margins of the pronotum are never 
laminate-dilated. In the type specimen of Agrammodes costatus 
this margin is explanate, a fact indicated in Uhler’s description 
by the expression “lateral margins a little reflexed.”’ 
The more important structural characters of the genus Piesma 
are the following: Antenna: first joint globular to ovoid; second 
ovoid, shorter than first; third cylindrical, slightly enlarged dis- 
tally, usually the longest joint and at least as long as fourth; 
the latter clavate, finely pubescent. Head, with the juge pro- 
duced as slender processes, projecting more or less beyond tylus, 
and more or less connivent before it; ocelli usually distinct in 
macropterous specimens ; a double spine at the inner angle of each 
eye; beak extending slightly beyond fore coxe, first joint alone, — 
and second and third together, a little shorter than fourth. 
Rostral sulcus deep on head, the buccule high, thin and in- 
curved, deep also on forepart of prosternum, narrower and
