not at all canaliculate ; there are also specimens before me 

 from Queensland (Cloncurry) and New South Wales 

 (Moruya) that agree with the Victorian specimens. Although 

 not commented upon under the description of lanquida (the 

 type of which is in the South Australian Museum) this species 

 in general appearance is extremely close to it, having very 

 similar and curious elytral markings; but it differs in having 

 the three large prothoraeic foveae or excavations of that 

 species represented by shallow depressions only, the pro- 

 thoracic markings larger and more narrowly separated along 

 the middle, the head and abdomen immaculate, and all the 

 joints of the antennae pale at the base. 



COPIDITA LANGUIDA, Blackb. 



PL xiii., figs. 25, 26. 

 The pale markings on this species vary somewhat; the 

 two dilated spaces starting from the suture are considerably 

 larger on some specimens than on others, but their outer 

 edges appear always to terminate on or about the second 

 discal costa ; this costa is pale at the base, and the pale 

 portion is occasionally narrowly connected with the ante- 

 median mark ; on one specimen it is also connected with the 

 postmedian mark ; the margins are usually narrowly pale 

 throughout, but occasionally the pale portion extends to 

 neither base nor apex, sometimes only to the base. The fifth 

 segment of the abdomen is usually black right across the 

 middle, but occasionally is spotted at the sides only, each of 

 the three preceding segments has a conspicuous spot on each 

 side. Sometimes the eighth joint of the antennae is entirely 

 pale, and the ninth but little clouded towards its apex, but 

 the four apical joints (as also the third and fourth) are 

 subject to considerable variation. The tarsi are partly pale, 

 and the hind tibiae are pale to a variable extent, but the 

 pale portion never touches the base or apex, although always 

 nearer to the latter. There appears to be always a reddish 

 patch between the eyes. 



Copidita sloanei, Blackb. 

 PI. xiii., figs. 27, 51, 52. 

 There are several species before me that in general 

 appearance might be regarded as varieties of sloanei, but 

 that species may be readily distinguished by the apical joint 

 of the maxillary palpi of the male; this has a conspicuous 

 appendix, much as if a small supplementary joint had been 

 thrust in at the outer edge, near where the two apical joints 

 touch; the female (the type must have been a female, as the
