prosternum in front. Now if Zygocera priiinosa, Boisd., be com- 

 pared with various other species that have been described as con- 

 generic with it, it will be found that in few if any of the latter 

 is the intermediate tibia absolutely without any trace of the 

 oblique sinus [it is scarcely less marked in (Disterna) 2^lumifera, 

 Pasc, than in Zygocera canosa, Er.], and also that the form of the 

 prosternum varies somewhat [e. g. being very much different in 

 (Disterna) 'plumifera, and very little different in (D.) luguhris^ 

 Pasc, from the same in Zygocera pruinosa aud canosa\ On the 

 other hand the facies and style of markings differ so little except 

 in degree, and there is so striking a character common to all the 

 Australian species hitherto attributed to either genus, viz., the 

 presence in one sex at least of a large apical or subapical depres- 

 sion or fovea on the more or less glabrous last ventral segment, 

 that I do not see how they can be regarded as at most more 

 distinct than two closely allied genera. I cannot see how they 

 are to be differentiated more strongly than as follows : Zygocera, 

 surface nitid with scanty pubescence forming spots or fasciae, 

 external sinus of intermediate tibise fairly well developed ; 

 Disterna, — pubescence much more extended on the surface render- 

 ing it in general opaque ; external sinus of intermediate tibite 

 almost or quite obsolete. 



The degree of contiguity of the base of the antennae varies but 

 does not seem to be generic [e. g. Z. canosa and D. luguhris appear 

 intermediate in this respect between Z. pruinosa and D. jylumifera'].

I have recently received from Mr. French, the Victorian Colo- 

 nial Entomologist, an example of this genus (hitherto not recorded, 

 as Australian), which that gentleman tells me was taken in North 

 Queensland. It does not appear to me to differ specifically from 

 picta, Fab,, which has a wide distribution in Polynesia.
