the scutelluin always being notably longer than wide at base, d'be sides 
of the body are noticeably more nearly parallel than in bullatas. d'be 
ground color is more yellowish, and the surface more polished, this being 
especially noticeable in the bemelytra. 
The varieties may be separated as follows: 
a. Scntelbmi almost wholly black ; a wedge-shaped area, consisting of 
scntellnm and parts anterior included in a triangle with scntellum 
at apex, largely piceous. decoratus var. decoralus Ubler. 
aa. Scntellnm with obvious yellow vittae; pronotnm with two longitudinal 
bands of dark color, one on each side of middle, these tending to 
disappear. decoratus var. solutxis iMontandon. 
Qeocoris decoratus var. decoratus Ubler. 
The typical variety is strikingly colored, the piceous wedge covering 
bead, most of pronotnm and scntellnm contrasting strongly with the clear 
margins of pronotnm and the almost wholly pale bemelytra. The piceous 
color is sometimes much diluted on |)ronotnm, but specimens in wbicb 
tbe outlines of the wedge shaped marking are preserved are classed with 
decoratus. Scntellnm sometimes with two yelloNV spots. Length 8 to 4mm.

The figure (d the type of this species given by Distant* represents the 
scntellnm of Uvidipennis as being longer than wide. The species there¬ 
fore belongs in the bullalun-decoratus group. The color characters, so 
far as the figure shows, pertain either to G. decoratus or to G. bullatas 
var. obscuratus. The name Uvidipennis would preoccupy either of these 
designations, but examination of the type is necessary before any change 
can intelligently be made.

■When tbe spots on scntellnm are enlarged so as to deserve the name 
vittae, the dark color on pronotnm usually becomes broken up into two 
more or less definite bands, one on each side of the middle, running from 
posterior liorder to the dark band in region of callosities. The tendency 
to jialeness is sometimes carried to such an extreme that there remain 
only traces of the bands in the form of dusky spots on hind margin of 
pronotnm and ring-like traces about callosities. Tbe baseand middle line 
of scntellnm usually retain their dark color. Length 3 to 4 mm. Kange;
