An obscure looking species of greenisli a-neous colour, bearing 

 much general resemblance to M. nervosa, Boisd., but without the, 

 elytral costa; of that insect, and having the prothorax more 

 transverse, with its sides straighter, and its gi-eatest width at the 

 base, &c.

S. atricollis, Saund. A short series of examples taken in the 

 Victoria Desert seems to me to be referable to this species in 

 spite of a degree of variation that to a casual glance certainly 

 appears incompatible with such an identification. Scarcely 

 two specimens in the series are quite alike. The extreme form 

 measures only 3| 1. in length, and the pale colouring on the 

 elytra is whitish-yellow, the markings and sculpture being not 

 much different from the typical form of atricollis, except in 

 the apical black colouring of the elytra, and the post-median 

 fascia being very wide. I think this form may perhaps be 

 conveniently named, and I shall call it " var. deserti." The 

 other examples are of varied size, up to 5 1. in length, and 

 in all of them (except one, the largest) the three spots in 

 front of the elytra are united into a fascia, which, however, 

 does not reach the lateral margins. In some of them the 

 oblique emargination at the sutural apex of the elytra is 

 extremely reduced in size, but is never quite absent ; the 

 apical spine is well developed in all. The colour gradually 

 through the series approaches that of typical atricollis. I 

 have been much puzzled by this insect, and have been very 

 unwilling to call it atricollis, but in spite of misgiving on 

 the point, much careful study has failed to bring to light any 

 constant character to distinguish it specifically.'
