sciitello puncturis nonnullis instructo, baud carinato ; elytris 

 sat crasse punctulatis, antice vix manifeste (postice sat 

 eviclenter) longitudinaliter costatis. Long. 2|- 1. ; lat., If 1. 



The prothorax is more gibbous than is usual in the genus ; it 

 has no dorsal channel, and is coarsely sculptured ; the dorsal 

 mark resembling the letter U does not quite reach either the base 

 or apex. The species should be placed among those with non- 

 costate elytra, although there are distinct traces of costse near the 

 apex, one or two of which appear from some points of view to 

 run forward a little further than the rest. The markings on the 

 elytra are very much as in C. histrionicus, Chap., or a typical 

 example of C. crucicoUis, Boisd. From the latter of these the 

 non-costate elytra furnish a good distinction, from the former the 

 slender antennae, which are a little longer than two-thirds of the 

 body.

P. suturcdis, sp. nov. $ Minus elongata ; minus convexa ; 

 testaceo-ferruginea ; capite (parte circa oculos excepta), 

 prothoracis macula media longitudinali et nonnullis utrinque 

 minoribus, scutello, elytrorum sutura humerisque, antennis 

 (articulis 2-5 exceptis), metasterni macula media triangulari, 

 femoribus subtus et supra, tarsorumque articulis ultimis 2, 

 nigris ; antennis corpori longitudine sequalibus ; prothorace 

 ad latera fortiter denticulato ; scutello longitudinaliter 

 fortiter carinato, opaco (carina marginibusque nitidis ex- 

 ceptis), crasse ruguloso; elytris confuse sat fortiter punctu- 

 latis. Long., 3 1. ; lat., 1^1. 



$ Multo magis convexa, antennis corpore multo brevioribus 

 rufis (articulo 1° excepto), elytris maculis nigris sat 

 numerosis ornatis. 



A male Prionopleura in the South Australian Museum 

 (habitat unknown) seems to be referable to this species, although 

 its antennae considerably longer than those of the type, and the 

 absence of a black humeral spot on the elytra may possibly indi- 

 cate a new species. 



South Australia ; near Port Lincoln. 



The only species previously described as presenting the combi- 

 nation of non-costate elytra with a prothorax strongly crenulate 

 on the sides are P. cognata, Saund., 4:-tuhercuIata, SufF., 

 hisfrionica, Chap., and rugicoUis, Gray. Of these, the former 

 two are said to l)e the sexes of a single species, the male of which 

 (4: tuberculata) differs from the present species inter alia by its 

 pallid antenna? and tubercled elytra, the female (cognata) by its 

 very different markings, yellow scutellum, ttc. ; while histrionica, 

 Chap., may be at once distinguished from it by the strongly com-
