160 INSECTA. 
ScuTELLERA, Lam.—Tetyra, Fab. 
Where the scutellum covers the whole abdomen. 
S. lineata; Cimec lineatus, L.; Wolf, Cimic., I, ii, 2. Length 
four lines; red, longitudinally striped with black above; black 
points arranged in lines on the venter. Environs of Paris and 
south of Europe, on flowers, the Umbelliferze, particularly *. 
Pentamona, Oliv. 
Where the scutellum covers but a portion of the superior part of 
the abdomen. This genus of Olivier forms five in the system of the 
Ryngota of Fabricius; they are, however, as imperfectly characterized 
as they are badly arranged. His Atlia, and Halys, are Pentatome 
with a head more prolunged and projecting in the manner of a snout, 
and more or less triangular. Among the species which he refers to 
the first, that which he calls the aewminata, and which is the Punaise 
a téte alongée of Geoffroy, appears to be essentially removed from the 
Pentatome by the antennze, which are covered at base by the anterior 
margin of the thorax, and seperated from it underneath, and by its 
much larger scutellum, which approximates this Insect to the Scu- 
telleree. In his Cydnus, the head, viewed from above, is wide and 
semicircular; the thorax forms a transversal square, hardly narrower 
before than behind, and the tibize are frequently spinous. These 
species remain on the ground. Of this number is the Punaise notre 
of Geoffroy. We might also approximate to them, as has already 
been done by MM. Lepeletier and Serville—Encye. Méthod.—certain 
species in which the sternum is neither carinated nor armed with a 
spine. Such are the two following: 
P.ornata; Cimez ornatus, L.; Wolf, Cimic., II, 16. Length 
four lines and a half; figure of a rounded ovoid; red, multima- 
culate; head and wings black.—On the Cabbage and other Cru- 
cifere. 
P. oleracea; Cimezx oleraceus L.; Wolf, Ib., 11, 16. Length 
three lines; ovoid; bluish-green with a thoracic line, a dot on 
the scutellum, and one on each elytron, white or red. 
Other Pentatomze in which the poststernum or mesosternum is 
raised into a carina, or presents a spiniform point, would be distin- 
guished by the generic appellation of EpEssa, employed by Fabricius. 
Several of the species which he includes in that genus present this 
character. It is also visible in several of those which belong to his 
Cimex, such as the two following Pentatome : 
P.hemorrhoidalis; Cimex hemorrhoidalis, L.; Wolf., Ib., 1, 
10. Length seven lines; ovoid; green above, yellowish beneath; 
posterior angles of the thorax extended into an obtuse point; a 
large brown spot on the elytra; back of the abdomen red, spotted 
with black. 
* For the other species see Fabricius, Syst. Ryngot., genus Tefyra. According 
to Dalman—Ephem. Entom., I.—his genus Canopus differs from the preceding one 
in tne following characters: the body more inflated, slightly compressed, concave be- 
neath, with the margin of t'e scutellum pendent over the sides; no simple eyes; 
legs unarmed.
