ment of abdomen scarcely twice the length of 2nd; 2nd feebly 

 convex, its outer apical edges rounded off; intermediates flattened, 

 a little shorter than apical; apical feebly convex. Legs elongate; 

 posterior femora scarcely reaching apex of abdomen ; tibiae 

 straight; tarsi narrow, 3rd joint rather widely bilobed, 4th not 

 as long as two basal combined. Length 17^, rostrum 5; width 

 10 mm. 



ZTai.— Queensland (Herr J. Faust) ; Tweed River, N.S.W. 

 (Lea). 



I have but one specimen of each of this and the preceding 

 species. They strongly resemble each other, but though P. idohis 

 is probably 9, and P. intermedius probably $, I do not take them 

 to be sexes of one species, there being too many structural 

 difierences between them. 



I have recently had for examination an abraded male specimen 

 from Herr J. Faust under a MS. name which I have adopted. 



Group F. — Type P. Chevrolati. 



Narrow, elongate-elliptic, convex, tuberculate. Rostrum almost 

 straight, scape inserted close to apex, considerably passing muzzle, 

 2nd joint of funicle a little longer than 1st (in Jekeli double its 

 length). Prothorax carinate; apex produced, narrow, bifurcate; 

 usually with two tubercles on each side and one on each side of 

 carina. Scutellum absent. Elytra widest at middle where they 

 are usually bulged out ; apex with two distinct more or less 

 triangular tubercles touching at bases; without distinct tubercle 

 in middle of sides of posterior declivity ; shoulders narrow. 

 Femora never reaching apex of elytra. Third tarsal joint 

 strongly bilobed. 

 Prothoracic carina narrow, in the centre of a shallow 



depression, extending from apex to base ; apex 



almost rounded. Elytra feebly tuberculate, apical 



tubercles short flexitosas, Pasc. 



Prothorax without depression, without feeble traces 



of tubercles, carina extending from apex to base, 



raised, shining, very distinct. Elytra with 



numerous small tubercles, apical largely produced, 



their internal edges almost parallel ellipticus, Pasc.
