588 Mr. W. L. Distant on Australasian Pentatomidae. 



truncate, lateral margins oblique, slightly rounded, lateral 

 angles subprominent, rounded; scutellum longer than broad, 

 its apex rounded ; corium as long as head and pronotum 

 together; membrane passing the abdominal apex, the veins 

 longitudinal; rostrum passing the posterior coxae, first joint 

 not reaching base of head, second extending to anterior 

 coxa?, third to intermediate coxae ; sternal process not ex- 

 tending beyond anterior margin of prosternum, apically 

 rounded and depressed to margin of prosternum ; legs of 

 moderate length, somewhat robust, femora distinctly thick- 

 ened, posterior tarsi with the basal joint a little shorter than 

 second and third joints together; sixth abdominal segment 

 centrally long, apical segment short, broad, posteriorly 

 concavely sinuate. 



Allied to Diaphyta by the large size of the head, but 

 differing in the structure of the sternal process, which is 

 more laminate, raised, and roundly arched at termination, as 

 is found in the genera arranged with Rhynchocoris. 



Vandiemenia tasmani, sp. n. 



Pale testaceous ; lateral margins of head and margins of 

 the central lobe (narrowly and not reaching apex) black ; 

 antennae brownish ochraceous, fourth and fifth joints black ; 

 pronotum with the basal area sometimes suffused with 

 blackish ; lateral and apical margins of the scutellum 

 narrowly black, sometimes obsoletely so towards apex ; 

 membrane pale fuliginous, subhyaline, reflecting the dark 

 abdomen beneath ; body beneath and legs pale testaceous, 

 apices of tibiae and the tarsi infuscate ; a spot near anterior 

 and intermediate acetabula, spots to connexivum (above and 

 beneath) at segmental apices, and apex of rostrum black ; 

 upper surfaces of tibiae thickly minutely spotted with black; 

 head finely wrinkled ; pronotum sparingly punctate, ex- 

 cluding the cicatricial areas, a distinct transverse series of 

 strong punctures before the anterior margin, the lateral 

 margins narrowly levigate and slightly reflexed ; scutellum 

 sparsely punctate, more strongly so on lateral margins and 

 apical area ; corium thickly finely punctate ; other structural 

 characters as in generic diagnosis.
