 Issus Fa'bricius. 



Issus Fa'bricius 1803 Syst. Rhyng.. 99; Melichar 1896 Cic. 

 Mittel-Eur. 40, PI. Ill, figs. 22-5. 



The following three species very probably will not be referred 

 ultimately to the genus Issus, as t'he frons and clypeus do not 

 altogether lie in t'he same plane. They cannot be Ulixcs Stal, 

 as in that genus t'he scutellum is said to be twice as long as the 

 pronotum. 



I. viilturnus, sp. nov. 



Vertex, pronotum and scutellum testaceous of various de- 

 grees of sordidness; frons and clypeus sordid brown. Tegm.na 

 dirty brownish, a transverse -band (a little basal of the middle), 

 the commissure, etc., dirty whitish. Legs dirty brownish, paler 

 in places. Beneath sordxl. Wings dark smoky. Vertex slight- 

 ly transverse (apical margin very obtusely angulate), narrower 

 than an eye. Frons with a round sublateral carina, and also a 

 median longitudinal one, both sli'giht but noticeable; postero- 

 lateral angles rounded, posterior margin roundlv emarginate; 

 outside the round carina are small granules. Eyes, in profile, 

 occupying nearly the whole of the 'head as far as the antennae. 

 Pronotum granulate, medianly carinate. Tegmina about 3 

 times as wide (max.) as head and eyes together; veins strong, 

 with numerous strong transverse veinlets (including costa and 

 clavus). Cubital and median veins forked at about the middle. 



Male: Pygofers black, polished, short, acute. 



Length: 6 mill., maximum width 3 mill. 



Hab: Queensland, Brisbane (vi), arboreal. 



2. sidnicus, sp. nov. 



Allied to the previous species, but smaller. The colorings 

 and picturation are practically the same except that within t'he 

 round carina of the frons, the color is castaneous, suffused with 

 blackish on the disk, and there is a short, transverse, whitish 

 stripe in the middle. Vertex about as wide as an eye, a trifle 

 more transverse than in vulturnus; scutellum scarcely longer 

 than the pronotum. Frons longer than wide, more swollen 

 medianly and more granulate outside t'he round carina, lateral 

 margins less divergent. Cubital vein forked a little nearer the 

 apex than the median. 



Male: Pygofers similar to the previous. 



Length: 5^ mill. 



Hab: New South Wales, Sydney (i), arboreal.
