 coxae.

SmicrocoHs gen. nov. 



Allied to the preceding, but the head is somewhat recurved, 

 the frons more convex and the striation on head and pronotum 

 tnuch coarser, the venation different, etc. 



Vertex very narrow, the basal margin not so emarginate as in 

 Sienocotis^ apical margin only slightly arched, recurved, the longi- 

 tudinal (suboblique) striations very coarse ; ocellar grooves 

 shorter and rounder: frons more convex, antennal ridges thicker. 

 Pronotal striations coarser. Tegmina with 5 discoidals (2 basal 

 and 3 subapical ; the latter quite different.) 



I. obscura, sp. nov. 



Dark brown, irrorated with black (which forms several more 

 or less distinct longitudinal lines on the pronotum.) Frons basal- 

 ly blackish brown. Tegmina pallid, mottled closely with brown 

 and brownish black. 



Length : 10 mill. 



Hab : Queensland, Cairns (viii.) 



Nymph : ( ?belonging to this genus.) Head produced in front, 

 then diverging rapidly posteriorly, longitudinally carinate, spi- 

 nosely produced just above the eye. Posterolateral angle of 

 pronotum spinose. 



Hab : New South Wales, Sydney (ii.) 



Kyphocofis, gen. nov. 



Closely allied to Sfcnocotis but the posterior three-fifths of the 

 scutellum are elevated in a narrow, acute crest, which in profile 

 is more or less rounded.
