PSALIDURA BREVICAUDA, n. Sp. 



d ■ Moderately large, elongate, subparallel. Black; 

 densely clothed with greyish-brown scales ; beneath with yellow 

 subsetose scales at sides of segments and yellow setae scattered 

 throughout, fifth segment similarly clothed, and on forceps 

 and apical ptergite, also with longer stouter setae; setae yellow; 

 fascicles dark-brown. 



Head strongly convex, densely clothed, sparingly setigero- 

 punctate. Rostrum short, moderately deeply excavate, ex- 

 ternal ridges feebly bisinuate in outline, internal less pro- 

 minent, short, strongly convergent, but apices separated. Eyes 

 large, ovate. Prothorax (7x7 mm.) strongly rounded on 

 sides, apex with median lobe strongly produced over head, 

 ocular lobes well denned but less prominent, collar impression 

 moderately marked, median line feeble; disc evenly and 

 closely set with small, round, little prominent, strongly seti- 

 gerous granules; sides granulate. Elytra (12x8 mm.) little 

 widened on sides, apex strongly rounded, feebly mucronate, 

 base subtruncate, humeral angles subnoduliform ; with rows of 

 small regular f oveif orm punctures, intervals between setigerous 

 but not granulate; interstices with small round setigerous 

 granules, on second, fourth, and sixth in single, on the others 

 in double, series; sides similar. Metasternum rather strongly 

 depressed in middle. Fifth segment strongly excavate, anterior 

 border of excavation hardly reaching anterior margin of seg- 

 ment, preanal fossa deep, transversely oval, not separated 

 from rest of excavation by a ridge, posterior margin of seg- 

 ment lightly fringed with setae ; fascicles set obliquely inwards 

 and downwards 2 mm. apart at base, 1 mm. at apex. Forceps 

 with apices alone evident, short stumpy, not meeting, laminae 

 present, very small and only visible from behind ; apical tergite 

 bearded with yellowish hair. 



9 • Of a more elliptical shape, in structure closely 

 resembling d" ; beneath convex, intermediates longer, fifth 

 without excavation, clothed with yellow setae except over small 

 bare area in centre. 



Dim. — $ , 20 x 8 mm. ; 9 , 20 x 8 mm. 



Hab. — Queensland: Dalby (Mrs. F. Hobler, per A. M. 

 Lea), Fraser Island (Bailey, South Australian Museum). 



Type in author's collection. 



One of the most remarkable species in the genus, not only 

 in the short forceps and curiously placed fascicles, but in the 

 very regular foveate elytral sculpture. It is not close to any 

 other known to me, and cannot with propriety be forced into 

 any of the groups in my table. Provisionally it may be formed 

 into a new group, in the table coming near the end and
