 one-half abdominal length, finely polygonally sculptured; remaining 

 Segments short, smooth.

 narrower than the pedicel; Ist twice as long as wide; 2nd one-half

(From 1 specimen, etc.) 



Male: Unknown. 



Described from a Single $ specimen caugth on a window, 

 Nelson, N. Q., 19th April, 12 (A. A. Girault). This is the second 

 Australian species of the genus, but it is easily distinguished from 

 the other species, fasciatipennis Dodd. 



Habitat: North Queensland (Nelson, near Cairns). 



Type: South Australian Museum, a $ tagmounted plus a slide 

 bearing head, antennae and forewings. 



Hadronotoides nov. gen. 



I erect this genus to contain the common species Hadronotus 

 pentatomus Dodd. 



The following characters: Like Hadronotus Foerster but the 

 scutellum is very large, deeply bidentate, the teeth projecting 

 over the short metanotum; metanotum with a short blunt tooth. 



Type: Hadronotus pentatomus Dodd, 1913. 



Genus Hadronotus Foerster. 



1. Hadronotus (Telenomoides) nigricoxa Dodd. 



The species Telenomoides nigricoxa Dodd is wrongly placed. 

 It is a Hadronotus Foerster. The name nigricoxa is preoccupied 

 by another species Hadronotus nigricoxa Dodd. I therefore propose 

 the new name Hadronotus nigricoxella for the species.
