abnormal specimen. Besides the characters distinguishing H. 

 considaris from H. moniliferus that Mr. Pascoe mentions, it may 

 be noted that the example of the former before me is more convex 

 than its ally, and has the flattened margin of the elytra narrower 

 and less horizontal while the shoulders of the same are less pro- 

 duced forward. 



Saragus rugosus, Boisd. 



I have lately received from Mr. Duboulay an example (taken 

 in Victoria) of a Saragus which seems very likely to be this species. 

 The description is too brief to allow of certain identification, but 

 as the species before me presents the characters mentioned by 

 Boisduval, and does not seem to have been described under any 

 other name, I think Boisduval's name may be assigned to it 

 It is exceedingly closely allied to S. IcevicoUis, Fab., from which it 

 diflTers as follows : — it is smaller (long. 6^, lat 2 J lines), the costse 

 and tubercles on the elytra are evidently stronger (the latter being 

 more numerous and more conical), both prothorax and elytra are 

 considerably more widely margined, and the tooth at the external 

 apex of the anterior tibiae is much smaller. 



Of the allied species subsequently described the present insect 

 differs from S. Odewahni, Pasc, catenulatus, Macl., rudis, Macl., 

 incequalis, Blackb., Lind% Blackb., latus, Blackb., and mediocrisj 

 Blackb., by its non-granulate prothorax, the sculpture of that 

 segment being quite as in S. loivicollis. 



Trichosaragus, gen. nov. 



Sarago affinis, sed difFert corpore pilis (supra perlongis erectis, 

 subtus brevioribus minus erectis) densissime vestito ; prothorace 

 sat anguste, elytris nullo modo, ad latera dilatatis ; mesosterno 

 antice vix concavo ; prothoracis tibiarumque anticarum et inter- 

 mediarum marginibus externis fortiter serratis. 



I feel some little uncertainty as to the real affinities of the 

 remarkable insect I am now describing, as I know of nothing to
