"beliiiid, tbere are obscure traces o£ raised interstices between 

 the scarcely indicated striae. The peculiar form of the thorax 

 distinguishes this insect from all other species that bear any 

 resemblance to it. 



I possess a single specimen taken near Sedan by Mr. Eothe- 

 and generously presented to me. 



M. soror sp. no v. Oblongo-ovalis ; subnitida ; senea velnigro- 

 senea, apicem versus nonnullis exemplis obscure cuprea ; 

 subtus cupreo-senea, tibiis anticis tarsisque viridibus ;. 

 capite piano sat fortiter punctulato, capillis longis albidis 

 confertim obsito ; prothorace quam longiori fere duplo 

 latiori, antice quam postice minime angustiori, sat fortiter 

 sat crebre punctulato, ad latera longe albido-pubescenti 

 transversim rugato, antice bisinuato, basi rectilineari, 

 lateribus fortiter rotundatis basi subparallelis ; elytris- 

 pone medium leviter dilatatis hand striatis, squamose nee 

 crebre punctulatis, punctis antice et latera versus trans- 

 versim confluentibus, sutura et lineis duabus (externa 

 subobsoleta) pone medium leviter elevatis, lateribus 

 pone medium serratis : subtus longe albido-pubescens, 

 prosterno antice transversim declivi, medio sat crebre 

 fortius, metasterno medio sparsim fortius, abdomine 

 sparsius squamose punctulatis. Long 5f — 7 1. 

 An obscure looking insect somewhat allied to M. nervosa^ 

 Boisd. Its characteristic features seem to be — on the upper 

 surface a strongly transverse thorax, which is strongly rounded 

 on the sides (the curve ending just before the base and the 

 sides then being straight), and is not much narrowed in front ; 

 and elytra without any distinct striation, but bearing each a 

 fairly dejfined convex ridge about where the second interstice 

 might be expected if the elytra were striated (which, however, 

 is scarcely raised above the surface in the anterior half, and 

 does not reach the apex), some faint indication of a second 

 ridge very much abbreviated at both ends about where the 

 fourth interstice should be, and the suture pretty strongly 

 raised in its posterior half; and on the under surface an 

 obscure coppery gloss (especially about the hinder part of the 

 abdominal segments) together with a presternum gently and 

 shortly bent over or depressed along its anterior margin. In 

 some species (5. nervosa for instance) the prosternum has its 

 front margin quite in the plane of its surface, or even very 

 slightly raised. The pubescence is very similar to that of 

 JB. nervosa. 



I have received this insect from Mr. Eothe, of Sedan, and 

 there are several specimens in the South Australian Museum 

 devoid of any record of capture,
