PSALIDURA INTERMEDIA, 11. sp. 



(? Of size and general form of variolosa. J31ack, sparsely clothed 

 with feeble greyish scales; setae long, dark l>rowii. Fascicles red; 

 anal hair black and reddisli. 



Head and rostiuni as in rartolosa. Prothorax (5 x 6 nun.) ain}>li- 

 ate, median lobe strongly produced, collar impression feeVjly 

 marked, closely set with small, I'ovind, strongly setigerous grannies, 

 not abraded nor umbilicate, rather smaller in centre. Elytra 

 (10.5 X 7.5 mm.) with rows of shallow transverse foveae, intervening 

 ridges feebly granulate, setigerous; interstices with rounded, strongly 

 umbilicate, setigerous granules, those nearer base feebly flattened, 

 in single series on second, fourth and sixth, tending to duplication 

 in centre, in double series on third, fifth and seventh. Sides with 

 setigerous non-umbilicate granules. Anal excavation wide and 

 deep; fascicles large, closer together than in ir/Ieo.ri ; posterior 

 edge strongly beaded with dark hair or bristles, extending across 

 middle line, intermediate row of a bright red colour, set farther 

 away from posterior row than in rnr/olosa, and continued across 

 middle line; apical tergite bearded. Foixeps short, apices acute, 

 touching; laminae obli(]uely set. 



$ Like variolosa, ( j ). 



Dimensions. — cT J.7 x 7.5 mm. ; ? 19 x 8 mm. 



Hah. — Queensland, Stanthorpe, Dalveen (H. J. Carter and T. 

 O. Sloane). 



The arrangement of tlie anal hair is a bit difficult to make out, 

 the intermediate row appears to be directed inwards and somewhat 

 forwards until on a level with the fascicles on each side, thence the 

 bristles are continued in an arc parallel with the posterior edge, and 

 continuous across the middle line. It seems closest to /'. irilcoxi, 

 but is a larger species, in general appearance more rcsenililing P. 

 variolosa. The distinctions between the species of the /'. irilcoxi 

 group may be tabulate<l as follows : — 



HO (t)3) Klytral interstices finely and distinctly i^rannlate. 

 61 (62) Snpramunary tufts (intermediate row) reddisli. 



a. Intermediate row not continued aciv^ss middle line. 



aa. Bristles continued iutoss middle lin

 (52 (»)1) Intermediiite row of lirisflos Mark. 



1). Posterior vow of bristles not continuous across middle line. 



P. vafioliisti. h'cr;;-. 

 bl). Posterior row continuous across middle lini'.

 <)3 (OO) Elytral interstices costate.
