HEMIPTEKA HETEROPTERA. 539 



The move acute lateral lobes of tlie 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 to a third group.

SciOCOEIS INDICATOR. 



Cervinus, ovalis, planus subtiliter punctalus, sub/us convexus; caput 

 productum, lobis lateralibus acutis Inbum medium paullo super- 

 art tibus ; antennce nigrce, graciles, basi teslacea; thoracis anguli non 

 producti ; scutellum apice latum, angiitis basalibus tcslacco-nigris ; 

 abdomen plagis duabus ventralibus nigricaniibus, gutlis marginalibns 

 nigris ; pedes pallide testacei, nigro conspersi ; alte anticee breves, 

 membrana cinerea trivenosa, vena media trifurcata. 



Fawu-co!onr, oval, thickly and finely punctured, flat above, convex, 

 beneath. Head much longer than broad, rather louger than the thorax; 

 lateral 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 coxa?. Antennae 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 

 tri furcate. Length of the body 2^ 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. hurneralis and *S'. obscurus. Of 

 these .S". obscurus comes near to the European group, while the other two 

 species approach Pentaloma, as do also all the species of the Australian 

 genus Dictyotus, to which .S'. proximus is nearly allied.
