following — N.B. labial palpi scarcely thicker than the max- 

 illary and with only three joints, maxillary with only Jour. 

 (The same is the case with all the species tabulated 

 above !) 23. 



— Antennae with 6 joints distinctly separated from the club. 

 Labial palpi much thicker than the maxillary, and four- 

 jointed; maxillary palpi sf'.r-jointed (Genus, or Subgenus?, 

 Xyloperga, Shipp = Heplacobt, Konow). In this latter 

 character the Group agrees with practically all non-Aus- 

 tralian Tenthredinidae except a few in Central and South 

 America ! 32. 



23. Antennae far longer than in any other species; all their joints 

 before the club slender and elongate (joints 3 and 4 subequal, 

 5 a little longer, and more than half as long as the club). 

 All these joints and the base of the club are black, its 

 apex is white (PI. XV, Fig. 20). Abdomen bright testaceous 

 above, whitish beneath, blackened on each side, these lateral 

 black vittae successively widening posteriorly and so spreading 

 more and more on to the dorsum, till on the penultimate 

 segments they actually meet. 



cameronii, Westwood = leucomelas, Rohwer. 



This is a very distinct and remarkable species. Un- 

 fortunately in Westwood's Type-specimen the antenna!' 

 are wholly wanting and were so when he figured and 

 described it. But in the Type-specimen of leucomelas, 

 Rohwer, which I have carefully compared with West- 

 wood's Type of cameronii, and which, I feel sure, is con- 

 specific with it, the antennae are perfect, and at once 

 suffice to distinguish the species from any other. Cf. 

 PL XV, Fig. 20 (drawn from the Type of leucomelas). 



Type of cameronii at Oxford, of leucomelas in B.M. 

 Westwood cites no particular locality for cameronii. The 

 Type of leucomelas is from Queensland (Cairns). 



Species with normal antennae, and very different coloration 



from cameronii 24. 



24. All tibiae and tarsi quite black. Abdomen red and very shining. 

 Antennae and scutellum black. Fore-wings with a strong 

 brownish clouding below the stigma. Length about 14-15 mm.
