Hetevoptevoiis Hemiptera. 29' 



Distant has described an Australian genus Pseudaelia which he 

 says is allied to Luhentins, but from its characters — especially th& 

 structure of the rostrum and abdomen — it is evident that it is only 

 ilistantly related to this genus and cannot be placed in the same- 

 group.

Pktalaspis, n. gen. 



Body obovate, convex before middle, the head and the anterior 

 liart of pronotuni being rather strongly declivous in the same 

 plane. Head a little broader than long, narrowing toward the 

 rounded apex, laterally moderately sinuate, clypeus .scarcely longer 

 than juga, subparallel, eyes rather large but not much projecting, 

 ocelli four times more distant from each other than from eyes,, 

 antenniferous tubercles i:)artly visible from above, antennae five- 

 jointed, first joint not reaching apex of head, bucculae percurrent,. 

 rostrum somewhat passing hind coxae, first joint as long as buc- 

 culae, second scarcely longer than third, fourth slightly shorter 

 than third. Pronotum at apex as broad as head, the area between 

 the non-elevated apical margin and the cicatrical areas still more 

 thickly and finely punctulate tlian the remainder of the disk, 

 lateral margins obtuse, broadly and slightly sinuate, humeral 

 angles a little prominent, right-angled, postero-lateral margins 

 sinuate before base of coriimi, basal margin rather deeply sinuate. 

 Scutellum with straight lateral margins and frena reaching far 

 beyond its middle, acute at apex but with a 

 laminate appendage horizontally projecting on each 

 side from under the apical part ; this appendage 

 beginning immediately behind the frena, slightly- 

 narrowed from the base to its subtruncate apex and 

 extending backwards beyond the true apex of the 

 pjg 1 scutellum (cf. fig. 1). Hemelytra but little passing- 



apex of abdomen, corium with slightly rounded 

 apical margin, membrane witli numerous simple veins. Metas- 

 ternum with a robust median ridge raised above the level of the 

 coxae, sinuate posteriorly for reception of the ventral basal tubercle, 

 and continued forwards to apex of prosternum, being narrower but 

 roundedly more raised under the prosternum and obliquely sub- 

 truncate at apex. Abdomen beneath ((?) roof-shaped, armed at 

 base with an acute tubercle directed forwards, apical angles of the
