Sciocoris rubens, sp. u. 



Testaceous with piceous mottlings ; head al)oiit as long as 

 breadth between eyes, the central lobe distiuctlj' prominent, 

 thickly punctate, the lateral margins paler and spotted with 

 piceous, eyes prominent, not quite reaching anterior prouotal 

 angles ; antennse ochraceons, basal joint not reaching apex 

 of head, second joint slightly shorter or subequal in length 

 to third, fourth and fifth longest and subequal ; pronotum 

 about twice as broad at base as median length, thickly 

 punctate, the lateral margins sublaminately reflexed, paler in 

 hue and finely spotted with piceous, basal margin narrowly 

 black ; scutellum about as long as broad at base, the basal 

 angles foveate, a longitudinal fasciate spot formed by blackish 

 pnnctures on each lateral area, not reaching apex, a small 

 but distinct black marginal spot on each side before apex ; 

 corium thickly finely punctate, base of lateral margins 

 slightly laminate, paler and finely spotted with brownish ; 

 membrane piceons, not reaching the abdominal apex ; con- 

 nexi\aim ochraceons with brownish spots ; body beneath and 

 legs ochraceous ; posterior tarsi with the basal joint shorter

Adelaidena, gen. nov. 



Head about as long as broad at base, only slightly nar- 

 rov^ ed towards apex which is broadly subtruncate, the margins 

 slightly reflexed, distinctly declivous in front of eyes, which 

 are prominent but not reaching anterior pronotal angles ; 

 antennae five-jointed, basal joint not reaching apex of head ; 

 pronotum about twice as broad at base as medially long, the 

 lateral margins laminate, reflexed and roundly oblique, 

 anterior margin concave between the eyes, posterior margin 

 truncate, postei'ior lateral angles subprominent ; scutellum 

 longer than broad, narrowing to apex, lateral margins to 

 near apex oblique, slightly sinuate, about as long as pronotum 

 and head together ; corium longer than scutellum, its apical 

 angle extending to near the apical margin of the abdomen; 

 connexivum exposed ; membrane small but slightly passing 

 the abdominal apex, the veins mostly longitudinal; rostrum 

 reaching the posterior coxae, first joint reaching base of head, 

 second reaching anterior coxae, third longest ; femora 

 moderately thickened ; posterior tarsi with the basal joint 

 much shorter than the remaining joints together. 



Allied to Sciocoris and principally differing by the length 

 and shape of the scutellum.
