Var. B. Apex of elytra not glabrous, and not, or 

 scarcely, darker than the adjacent parts; subhumeral patch 

 on each elytron rather shorter than on typical form, partially 

 clothed towards the base and conspicuously bordered (intern- 

 ally and posteriorly) with paler clothing. Length, 18-29 

 mm. This form occurs from Victoria to Western Australia, 

 and is fairly common in the drier parts of South Australia. 

 The size of the subhumeral patch varies, and when long the 

 variety is only distinguished from the typical form by the 

 non-glabrous apices. The length and acuteness of the outer 

 spine varies, so that on some specimens it is but little more 

 acute than on simulans, from which, in fact, it is not always 

 easy to distinguish specimens of the variety. 



Var. C. Subhumeral patches with margining clothing 

 not conspicuously paler than elsewhere, apex of each elytron 

 acutely bispinose and not glabrous. Length, 21-24 mm. 

 This form has a similar range to Var. B, and is distinguished 

 from it only by the clothing at sides of subhumeral patches. 



A specimen, from Onslow, in Mr. French's collection, 

 might be referred to this variety ; it has the subhumeral patch 

 en the left elytron (on the right it is different, apparently 

 owing to abrasion) partially clothed, so that it appears to be 

 in three irregular parts, one humeral, one sutural, and the 

 other median. But practically, judging from the descrip- 

 tion, the only distinguishing feature of fitscocinerens was a 

 'basal patch similarly divided. 



Uracanthus fuscocinereus, White. 



The original description of this species is insufficient for 

 its positive identification, and it was possibly founded upon 

 one of the numerous varieties of triangularis. Its habitat 

 was given as "Australia," not New South Wales, as in 

 Masters' Catalogue. 



Uracanthus simulans, Pasc. 

 PI. xxxii. fig. 22. 



A specimen from the Blackburn Collection, labelled as 

 simulans, is 15 lines in length, another from Ouldea is 14, 

 "the smallest in the Museum (from Beverley) is but 8 ; but 

 the average is much the same as that of the types (10-11 

 lines) . 



There are several closely-allied species from which it may 

 be distinguished by each elytron acutely spinose at the sutural 

 apex and not elsewhere, and clothing immediately behind 

 glabrous elytra! patches not denser than elsewhere. On the
