Aulacophora and allied genera. 303 



segment in the <? is much more deeply excavated, whilst 

 the apex of the same segment in the ? is broader and 

 more obtuse ; the arrangement of the flavous colora- 

 tion of the elytra differs also in the two species ; in 

 Cartereti it forms a broad transverse band, which occu- 

 pies, or nearly occupies, the middle third of the elytron ; 

 in instabilis, on the other hand, this band is interrupted, 

 and in some specimens entirely obsolete on the sides. 

 I possess a <? specimen of Cartereti from Port Moresby, 

 in which a small fulvous spot is placed at the apex of 

 each elytron ; a ? from the same locality has the 

 legs and under surface of the body pale piceous. 



Sp. 70. hilaris, Boisd. 



nigrosignata, Baly. 



? Var. insularis, Jacoby ?. 



? pectoralis, Jacoby. 



The description of Boisduval (whose type is now, I 

 believe, lost), " Lutea, utrinque nigro hiciiicta," is too 

 brief to be assigned with the slightest degree of certainty 

 to any of the above species. I will therefore only add 

 that whilst hilaris and pectoralis are Australian forms, 

 nigrosignata and insularis are natives of the Malay 

 Archipelago ; the name pectoralis has, however, already 

 been used by Chapuis for a Philippine Island species, 

 and must be changed. I therefore propose to alter it 

 to Barrel. 



Sp. 73. analis, Weber. 



The Australian species described and figured by 

 Olivier, and usually standing in collections under this 

 name, is an entirely distinct specific form, which I have 

 described in my second paper, I. c, p. 184, under the 

 name of Olivieri. I have also, I. c, p. 176, recharacterised 

 the true analis, pointing out the structural and other 

 characters which separate the two species : analis, 

 Weber, is a native of Sumatra and the other islands of 

 the Malay Archipelago, whilst Olivieri is found in various 

 parts of Australia. 



The type and varieties of A. varians, Chapuis, belong, 

 I believe, to the present species.
