Journ. ix.), that it is difllcult to compare anything in precise 

 terms with such an aggregate. The distinctive characters of a 

 generic nature in the species before me are as follows : inter- 

 mediate coxal cavities closed externally ; head short ; antennae 

 with two or three joints having apical spines, but these extremely 

 small ; femora pedunculated at their base ; scutellum small ; eyes 

 very coarsely granulated ; prothorax more or less tuberculate 

 above and feebly and obtusely nodose on the sides ; elytra not 

 spined at apex, with smooth raised spots and strong puncturation 

 becoming finer and feeble only gradually and very near to the 

 apex. These characters are in the main the characters of Thoris 

 and I should judge from the description of the unique species of 

 that genus that the insects before me resemble it considerably in 

 superficial respects. Judged by the descriptions the names 

 Thoris and Allotisis may well be synonyms. 



The distinction between the Phoracanthides and the Callidiop- 

 sides seems to be very fine. M. Lacordaire mentions a genus 

 {Acyrusa) which he places in the latter aggregate in preference to 

 the former merely on the ground that its colouring and sculpture 

 are similar to those of a Callidiopsid genus. With this in mind it 

 seems well to remark that both the following species (especially 

 the former) decidedly have a Callidiopsid facies, but if it is 

 allowable to refer to the Callidiopsides insects having several 

 antennal joints spined I cannot see how the distinctness of the 

 two groups can be maintained at all. I must acknowledge that 

 in P.L.S. N.S.W., 1893, I very hesitatingly referred to the 

 Callidiopsides a species (Porithea plagiata) which has more than 

 1 antennal joint spinose but I now incline to think I was wrong 

 in doing so and that the species in question should be placed 

 among the Phoracanthides. 



T. septe}?iguttata, sp. nov. Rufo-testacea, elytris guttis septenis 

 parvis eburneis albidis ornatis ; pilis elongatis erectis sparsim 

 vestita ; in prothorace maculis nonnullis minus insignibus 

 aureo-pubescentibus instructa ; capite brevi subtiliter ruguloso ; 

 prothorace obscure punctulato, quam latiori sat longiori, supra 

 5-tuberculato, subcylindrico sed ad latera leviter nodoso ; elytris 

 sat grosse (prope apicem gradatim obsolete) subseriatim punctu- 

 latis, ad apicem obtuse truncatis.
