The markings of the elytra consist of a small but very con- 

 spicuous red patch on each shoulder. The species is somewhat 

 close to the preceding (5. Cowleyi) but is smaller and narrower 

 and notably more parallel, and is readily distinguishable also by 

 the very evidently less close puncturation of its head and the 

 much finer puncturation of the dorsal surface of the fourth seg- 

 ment of its abdomen. Compared with B. Murrayi, Macl., inter 

 alia the pronotum and head are considerably less closely punc- 

 tulate.

B. barronensis, sp. nov. Sat elongatus ; minus latus ; minus 

 convexus ; pubescens ; minus parallelus (abdomine a basi 

 retrorsum angustato) ; castaneus, elytris postice plus minusve 

 infuscatis ; capite prothoraceque crebre minus subtiliter 

 (baud multo aliter quam JS. plani, Er.), abdomine minus 

 fortiter multominus crebre, punctulatis ; prothorace trans- 

 verso, antice sat fortiter (ut B. hasalis, Er.) angustato 

 parum emarginato, marginibus lateralibus haud ciliatis, 

 angulis anticis obtusis posticis fere rectis (nee acute) haud 

 retrorsum inclinatis, lateribus leviter arcuatis ; elytris quam 

 prothorax (maris vix, feminsD paullo) latioribus tertia parte 

 longioribus, abdominis segment! 3' partem basalem tegenti- 

 bus, substriatis, interstitiis planatis vix prominentibus minus 

 perspicue punctulatis. 

 Maris (?) abdominis segmento b" ad apicem late rotundato- 

 truncato, segmento 6° brevissimo; feminse segmento 5° magis 

 elongato ad apicem minus late rotundato. Long., 14 1.;

' Readily distinguishable from its previously described Aus- 

 tralian congeners by the non-ciliate lateral margins of its pro- 

 notum and by the hind angles of that segment being (not sharply 

 but) bluntly right angles and not directed hindwards. I think 

 the two specimens before me are male and female but the 

 external sexual characters in that case are very slight (as seems 

 to be the case with most of the Australian Brachypepli), In 

 the specimen that I take to be a male the fifth dorsal segment of 

 the abdomen is shorter and blunter than in the other specimen 

 and beyond it there is (what looks like) an extremely minute
