HEMIPTERA HETEROPTERA. 539 
The more acute lateral lobes of the head indicate that the group 
of this genus is distinct from that represented by S. varicornis and 
S. philippinensis. In differs in like manner from S, indicus, which 
belongs w a third group.

Cervinus, ovalis, planus subtiliter punctatus, sublus convexus; caput 
productum, lobis lateralibus acutis lobum medium naullo super- 
antibus ; antenne nigre, graciles, basi testacee; thoracis anguli non 
producti; scutellum apice latum, angulis basalibus testaceo-nigris ; 
abdomen plagis duabus ventralibus nigricantibus, guttis marginalibus 
nigris ; pedes pallide testacet, nigro conspersi; ale antice breves, 
membrana cinerea trivenosa, vena media trifurcata. 
Fawn-colour, oval, thickly and finely punctured, flat above, convex 
beneath. Head much longer than broad, rather longer than the thorax; 
dateral lobes acute, extending a little beyond the middle lobe. Eyes black, 
small, prominent. Ocelli three, close to the hind border. Rostrum 
extending to the hind coxe. Antenne black, slender, testaceous towards 
the base, almost half the length of the body; third joint as long as the 
second, a little shorter than the fourth. ‘Thorax more than twice as broad 
as long, with a transverse callus on each side near the fore border; fore 
angles not prominent. Scutellum much more than half the length of the 
abdomen, broad and rounded at the tip, with a testaceous point and 
a black point on each basal angle. Abdomen beneath with a blackish 
patch on each side at the base; two rows of black marginal dots. Legs 
pale testaceous, with black speckles. Corium of the fore wings not 
extending to the tip of the scutellum; membrane cinereous, not extending 
to the tip of the abdomen, with three longitudinal veins, the middle one 
trifurcate. Length of the body 23 lines. 
The narrow and acute lateral lobes of the head distinguish it from the 
European species. It differs still more from the three Australian groups 
which are represented by S. proximus, S. humeralis aud WS. cbscurus. Of 
these S. obscurus comes near to the European group, while the other two 
species approach Pentatoma, as do also all the species of the Australian 
genus Dictyotus, to which Ss. provimus is nearly allied.
