considered. both by Stal and Uhler to be but a synonym of E. punctipes, Say. I 
have followed these two excellent authorities; but add, at the same time, a full 
description, as the few specimens I have examined are all perfectly constant, and 
cannot well be reconciled with Say’s description. 
Body above pale luteous white. Head with the following black markings—a narrow central longitudinal line, 
becoming broader posteriorly, and with a waved transverse fascia near centre, on each side of which is a 
waved longitudinal line, which together enclose a centrally divided cordate spot at base, on each side of 
which is a rounded spot; inner margin of eyes black, eyes castaneous. Antenne black, apical joint and 
extreme apex of third joint dull ochraceous. Pronotum coarsely and darkly punctate, and with two 
narrow transverse black fascie near anterior margin. Scutellum coarsely and darkly punctate, the base and 
a broad central longitudinal space black, and with a slightly raised, luteous, levigate spot near each basal 
angle. Clavus longitudinally punctate. Corium sparsely punctate on disk, the lateral margin and apical 
angle broadly impunctate. Membrane pale hyaline, considerably passing apex of abdomen. Body 
beneath pale luteous white ; sternum with a broad lateral margin of dark punctures; abdomen with a 
broad fuscous submarginal fascia, and with a dark fuscous impressed spot on the lateral margins of the 
three apical segments. Legs luteous, spotted with fuscous.

Prof. Uhler (Bull. U.S. Geol. & Geogr. Surv. ii. p. 306) placed this species as a 
synonym of G. bullata, Say. Subsequently, however (ibid. iii. p. 409), he has treated 
Say’s species as distinct, and, remarking upon its very varietal character, observes that 
‘‘ full series of these varieties are needed to settle the synonymy of this species and its’ 
allied forms. Some links, pointing to a connection with G. pallens, borealis, and 
discopterus, have already been procured; and doubtless still others will occur when 
closer attention is given to collecting them.” Prof. Uhler is the recognized authority 
on North-American Rhynchota; and I have therefore gladly followed him here. All 
the Central-American specimens which we have received through Mr. Champion are 
constant in character and of the form described by Mr. Dallas, of which I have examined 
the type. 
Subfam. PACHYGRONTHINA. 
Pachygronthida, Stal, Hem. Afr. ii. p. 121 (1865). 
Pachygronthina, Stal, En. Hem. iv. p. 188 (1874). 
Pachygronthine, Uhler, Bull. U.S. Geol. & Geogr. Surv. iii. p. 411 (1877). 
In the Pachygronthine the anterior femora are much thickened, spined beneath, and 
longer than the anterior tibie.
