the genus Hesperilla is the slight structural differences in the 

 antennae and palpi, but at present I see no reason for 

 dividing the genus any further than I have done. When we 

 become better acquainted with the earlier stages of the differ- 

 ent species, it may be advisable to erect new genera where 

 expedient, but as they form a tolerably compact group, and 

 are (with one or two exceptions) peculiar to the Australian 

 region, I prefer to retain them under the one genus. 



Watson distinguishes Hesperilla from Telesto by the 

 latter having "club arcuate without terminal crook," whereas 

 in the latter genus he considers the club "usually bent to less 

 than a right angle." Perornata and munionga will probably 

 require a new genus to receive them, as in characters they 

 appear to be intermediate between Hesperilla and Trapezites, 

 having the facies of the former and characters (in a degree) 

 of the latter. In this and the following genus I have 

 adopted a somewhat different arrangement from that in our 

 previous paper, as it appears to be more in keeping with the 

 proper sequence of the various species. 



Mabille's genus Oxytoxia was erected on the strength of 

 the stigma of male being oblique instead of erect, a rather 

 feeble effort and quite unnecessary. The suggestion to form 

 a new genus for Doubledayi, flammeata, and a few others 

 came from Watson (P.Z.S., 1893, p. 74). By some mis- 

 chance Mabille has made flammeata a synonym of Double- 

 dayi, but the stigma of flammeata is certainly widely different 

 from the others in places in his genus, i.e., Doubledayi, 

 parvulus, compacta, argento ornatus, and (?) croites. The 

 last-named two are referable to Anisynta.
