 as long, ot)m}>aratively broadly rounded at apex. Hemelytra almost

 obscurely crenulate in its basal part, membrane rather small, half 

 the length of corium. Abdomen witli the apical angles of the-

 margin obtusangularly sinuate, its apical angles slightly prominent. 

 Length, 3' 1).5 — 10 mm. 



Macdonnell Range ; Alice Springs. 



Not closely allied to any previously described species. I have 

 also seen an undetermined specimen of it in the British Museum. 



N.B. — In the males of C'ep/ialoplafiia, which were unknown ta 

 Stal, the sixth ventral segment is rounded at the V^ase, not angular 

 as in the allied genus Dicfi/ofiis, Dall. 



HypoLCUS, n. gen. 



Body oval, somewhat depressed. Head about as broad as long 

 and almost as long as pronotum in the middle, a little convex, 

 lateral margins subacutely narrowly carinated, rotundately angu- 

 lar, scarcely or very slightly sinuate behind middle, clypeus parallel 

 in its basal half, then narrowing toward the tip, juga a little longer 

 than clypeus, but neither meeting nor convergent in front of it, 

 subacute at apex, ocelli about three times more distant from each 

 other than from the eyes which are rather small but prominent, 

 touching apical margin of pronotum (in the normal position of the 

 head), narrowly oval when seen obliquely from before, their vertical 

 diameter being much longer than the horizontal, interocular space- 

 over four times broader than an eye, antenniferous tubercles small, 

 not visible fi-om alwve, antennae five-jointed, first joint very short, 

 little more than twice longer than broad, the three following joints 

 on the whole subequal in length though somewhat variable in thifr 

 respect, second not quite reaching apex of head, fifth a little longer 

 than fourth, the four last joints successively increasing in thick- 

 ness, bucculae low, percurrent, neither ampliated nor angular at 

 anterior end, rostrum reaching beyond 'hind coxae, first joint 

 slightly passing bucculae, second shorter than the last two togethei-, 

 third shorter than second but longer than fourth. Pronotimi with 

 the apical margin neither elevated nor levigate, rather deeply 

 arcuately sinuate behind interocular space of head, truncate behind 

 eyes, lateral inargins not or very obscurely crenulated, not reflexed 

 l)ut laminately dilated, gradually more widely so toward the apical
