Bay. INSECTA. 
PrentTAtoma, 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 lia, and Halys, are Pentatomx 
with a head more prolonged 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 acuminata, and which is the Punaise 
a téte alongée of Geoffroy, appears to be essentially removed from the 
Pentatomz by the antennz, which are covered at base by the anterior. 
margin of the thorax and separated from it underneath, and by its, 
much larger scutellum, which approximates this Insect to the Scu- 
tellere. 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 tibiz are frequently spinous. These 
species remain on the ground. Of this number is the Punaise noire 
of Geoffroy. We might also approximate to them, as has already 
been done by Messrs Lepeletier and Serville—Encyc. Méthod.—cer- 
tain species in which the sternum is neither, carinated nor armed 
with a spine. Such are the two following: 
P. ornata; Cimex 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- 
ciferz. 
P. oleracea; Cimex arene Lis Wolf, Ib., II, 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 Pentatomz in which the poststernum or mesosternum is rais- 
ed into a carina, or presents a spiniform point,’ would be distinguish- 
ed by the generic appellation of Eprssa, 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 Sade ka to his 
Cimex, such as the two folldwing Pentatomz: 
P. hemorrhoidalis; Cimex hemorrhoidalis, L.; Wolf., Ib., I,- 
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 cape red, spot- 
ted with black. 
cave beneath, with the margin of the scutellum pendent over the sides; no simple 
eyes; legs unarmed. :
