gate first antennal joint and nmch shorter succeeding joints; the 
narrower head, with more sharply truncate occiput; the more 
elongate pronotum, which is narrower cephalad, with lateral 
margins more divergent caudad; the much more elongate wings, 
and the much less flattened, more nearly conical forceps of the 
female/'*' 
The genus is monotypic. Geiiotype. — Geracodes litus new 
species. 
Features of generic value are given in the key. These we con- 
sider to be; the ocular and antennal characters; the general 
pronotal character; the greatly elongate wings and absence of 
arolia. In addition, we would remark that the caudal metatarsus 
is very slightly longer than the combined length of the second and 
third tarsal joints and has the ventral surface hairy, with two 
rows of widely spaced, elongate, chaetiform spines. 
This genus would appear to be truly Labiine, but is apparently 
related to Barygerax, which, in turn, shares various characters 
with Gerax and Eugerax, which latter genera show a strongly 
Diplatyine development. 
Geracodes litus new species (Plate XXVI, Figs. 6 and 7.) 
This is a distinctive insect structurally; in general appearance 
resembling Labia minor, but differing widely from that species as 
shown above in the generic treatment.

[U. S. National Museum.] 
The features of major importance are given in the key and generic diagnosis. 
In addition we would remark the following. Form moderately slender. Head 
with margins of cheeks almost straight, slightly converging to the sharply 
rounded latero-caudal angles; caudal margin straight, truncate, cut by the 
distinct, medio-longitudinal, linear occipital suture. Pronotum with prozona 
convex ftnd lateral margins cingulate. Tegmina with transverse distal margin 
rounding broadly into the sutural margin. Wings with an elongate-trigonal, 
proximal portion at the sutural margin, smooth and pallid; apex more broadly 
truncate than in Labia minor, the distal margin straight, transverse. Ulti- 
mate dorsal abdominal segment almost entire!}' concealed,®’ weakly produced 
mesad in two weakly convex portions, with caudal margin weakly l)ilobate. 
Pygidium minute. Forceps stout, length slightly over twice the greatest prox- 
The male sex is unknown and will probably show other distinctive features 
for Geracodes. 
The abdomen is distinctly retracted in the only specimen before us.
