same, but the longitudinal elevations are even less defined. 

 The two males in the Museum are exactly alike in colour. 



MORPHOLYCUS COSTIPENNIS, n. Sp. 



d ■ Black ; parts of prothorax and elytra (except apical 

 third) of a rusty red. Sparsely pubescent, the elytra almost 

 entirely glabrous. 



Head and antennae much as in the preceding species. 

 Prothorax lightly transverse, sides somewhat unevenly 

 rounded, base lightly trisinuate ; with a wide and conspicuous 

 but not very deep median line, and with a somewhat shallower 

 depression on each side; punctures dense and sharply denned. 

 Elytra much wider than prothorax, very feebly dilated pos- 

 teriorly ; each with four acute discal costae, the suture and 

 margins also narrowly elevated ; punctures much as on pro- 

 thorax. Length ( <S , <j?)> 8|-10 mm. 



9 • Differs in being somewhat wider, antennae shorter 

 and less strongly serrate, legs slightly shorter, and abdomen 

 with the tip rounded, and without the small and notched 

 sixth segment of the male. 



Hab. — Queensland: Mount Tambourine (H. J. Carter 

 and H. Hacker); New South Wales: Tweed River (Black- 

 burn's collection, from R. Helms). Type, I. 6656. 



In general appearance the type is very close to the 

 typical form of a pica! is, but the elytra are acutely costate 

 and the antennae are much less acutely serrate. The longi- 

 tudinal impressions of the pronotum are not so deep as on 

 the preceding species, but the punctures are almost as large 

 as on the head, instead of considerably smaller. On the type 

 the prothorax is red, but with a large circular black discal 

 patch, its elytra have the black apical portion slightly 

 advanced along the suture : a second male closely agrees with 

 it in colour, except that the apical black patch of the elytra 

 is somewhat larger. A female (mounted with the type male) 

 has the black discal patch of the pronotum irregularly con- 

 nected with the apex, and its elytra entirely red, except for 

 a narrow posterior infuscation of the suture ; another female 

 has similar elytra, but the black prothoracic patch so ex- 

 tended as to leave only a narrow reddish strip at the base. 



MORPHOLYCUS MONILICORNIS, n. Sp. 



cS • Black, with a more or less purplish gloss ; elytra 

 purple, with the base, apex, and sides red, the red partly 

 advanced along the suture. Sparsely pubescent, but the 

 sides with moderately long, straggling hairs. 



Head with crowded and sharply-defined punctures. 

 Antennae rather short and stout, first joint rather short,
