the base and at a point a little in front of the middle. The 

 closely punctiilate depressions on the elytra bearing yellow pubes- 

 cence are very shallow and very large, and are very irregularly 

 placed, so that the nitid interspaces form an ill-detined and ex- 

 tremely open network, none of them appearing as continuous 

 longitudinal cost^, even that nearest to the suture being more or 

 less interrupted. It is not improbable, however, that there may 

 be some variation in this respect if in some examples the de- 

 pressed spaces happen to fall more into longitudinal lines. The 

 average area of these closely punctured depressed spaces is about 

 equal to that of the eye as seen from above, but in places two or 

 three of them almost coalesce, so as to form what on a casual 

 glance looks like a very large space indeed. 



A single example in the South Australian Museum is ticketed 

 ^'C. A." (Central Australia). Other specimens similarly ticketed 

 seem to be from the southern part of the tropical region.

ZOXITIS. 



Z. nigro-cenea, Fairm., var. (?) A. Nigra ; clypeo antice obscure 

 piceo ; elytris cwruleis, crassissime rugulose punctulatis, in- 

 terstitiis baud IsBvigatis. Long., 61.; lat., \^\. 

 The antennas are two-thirds the length of the body ; joint 1 is 

 slightly longer than 4, 2 scarcely half as long as 1, and two-thirds 

 the length of 3. The head is equal in length to the pro thorax, 

 and also to the first four joints taken together of the antenna* ; 

 the distfituce from eye to eye is rather more than the length of 

 the bas.al joint of the antennie, or about one-third the length of 

 the head. The labrum is nearly as long as the basal joint of the 

 antei;ni?e, ciliated in front and deeply channelled down the middle, 

 its surface shiny, with a few strong punctures. The clypeus is 

 truncate in front, its hind suture strongly angulated ; its surface 

 is shining and only obscurely punctulate, a deep furrow crossing 

 it near its base, its length about equal to that of the labrum. 

 The hind part of the head is strongly and somewhat rugosely 

 punctulate, and almost truncate behind. The prothorax down 

 the middle is barely longer than its greatest width, which is 

 s.lightly behind the middle ; its base is about a quarter again as 

 wide as the base of the head ; the width of its front is about 

 'one-third of its base, from which the sides diverge sinuously not 

 quite to the middle, where they are strongly rounded, and thence 

 converge sinuously to tlie front ; the front part of the suface is a 

 little depressed ; from this depressed space a very strong central 

 channel runs back to the base, and on either side of the channel 

 there is a large deep fovea on the disc. The scutellum is nitid, 

 and very sparsely, but not linely, punctulate. The elytra are
