11. INTERMEDIUS Szepl. 



Stephanus intermedins Szepl. , p. 533, 5 . 



5 • Frons coarsely and indistinctly arcnately rugose ; vertex 

 arcuately, occiput transversely rugose ; cheeks short, only half as 

 long as scape ; posterior margin of head shai'ply bordered. Basal 

 flagellar joints normal. Pronotum short, irregularly trans-striate, 

 its posterior margin polished. Mesonotum coarsely and irregularly 

 rugose ; scutellum smooth, with coarse marginal punctures. 

 Mesopleurse in front finely punctate, a few coarse punctures 

 behind and transrugose below ; metapleurae pubescent, with a 

 few isolated punctures, separated by a deep smooth sulcus from 

 the confluently punctate median segment. The petiole trans- 

 rugose, rather shorter than rest of abdomen. Terebra rather 

 longer than body, white-banded before apex. Hind legs with 

 coxpe trans-striate; femora smooth, bidentate ; tibiae compressed 

 in basal third. 



Black; head, scape, and hind tarsi ferruginous. Wings 

 infumate, light brown. 



Length 27 mm. ; terebra 30 mm. 



Habitat : Tonantins, Brazil, 



This species comes very close to H. macrurus Schlett., from 

 which it may be distinguished by the confluent puncturation of 

 the median segment, infumate wings, and much shorter terebra. 



11a. GRANULATUS Elliott. 



Hemistephanus granulatus Elliott (2), p. 130, $ . 



$ . Head, excepting the smooth temples, granulate rugose, 

 vertex and occiput moi'e finely ; posterior margin of head 

 bordered ; anterior tubercle prominent ; three very conspicuous 

 carinjB between the posterior ocelli. Basal flagellar joints normal. 

 Pronotum rather short, trans-striate, with smooth posterior 

 margin ; mesonotum centrally trans-striate, laterally punctate ; 

 scutellum closely punctate throughout, marginal punctures deep. 

 Mesopleurse finely and closely punctate ; metapleurae coarsely 

 punctate, separated by a crenulate sulcus from the median 

 segment, which is confluently, almost granulate punctate. Petiole 

 trans-striate, slightly shorter than rest of abdomen ; base of 

 second segment trans-striate, remainder smooth, feebly shining. 

 Terebra very nearly as long as body, rufescent. Hind legs with 

 coxse trans-striate ; femora smooth, bidentate ; tibise compressed 

 to middle. 



Rufescent ; all metatarsi flavous to white. Wings infumate. 



Length 13 mm.; abdomen 7| mm. ; petiole S^mm. ; terebra 

 13| mm. 



Habitat : Swan River, West Australia. 



The closely punctate scutellum and general granulate sculpture 

 will distinguish this species. 



If the label " Swan River " is correct, this is the first, and
