ME. E. SA-UKDERS OK NEW SPECIES OE STIGMODERA. 461 



Head and thorax black, with cyaneous reflections. Elytra dark red, with 

 just the base, a transverse somewhat semilunar spot starting from the 

 scutellum, its under margin being semicircular, and another larger 

 transverse diamond-shaped spot, midway between it and the apex, 

 cyaneous. Beneath legs and antennae cyaneous black. 



Head deeply punctured. Thorax once and three-quarters as broad as 

 long; anterior margin produced in the centre and at its angles, a 

 little more than half as long as the base ; sides rounded, their mar- 

 gins elevated, base with a wide central lobe ; disk largely punctured, 

 the punctures larger and closer together on the sides, with a slight 

 dorsal line; basal lobe terminated on each side by a deep small 

 pit. Elytra twice as long as wide, punctm-ed and deeply striate, the 

 striae becoming irregular on the sides, and the interstices rugose ; 

 sides slightly sinuate above the middle ; apex largely truncate. 

 Beneath and legs largely punctured, with a few scattered hau'S. 



Length 16 lines, breadth 65. 



Hab. N. Australia. 



Stigmodera sanguineocincta. (Plate IX. fig. 3.) 



Capite thoraceque aureo-viridibus ; elytris punctato-striatis, flavis, lateri- 

 bus sanguineis ; subtus viridis. 



Head and thorax brassy-green. Elytra testaceous, with their lateral 

 margins and apex sanguineous. Beneath and antennas green. 



Head punctured, widely channelled between the eyes, covered with short 

 white hairs. Thorax nearly twice as broad as long; anterior margin 

 slightly elevated, bisinuate, half as long as the base; sides rounded 

 above the middle, thence subparallel to the base, which has a well- 

 defined but shallow lobe ; posterior angles acute ; surface largely and 

 deeply punctured; disk with a smooth slightly raised dorsal line, 

 and two transverse irregular smooth spaces about one-third of the 

 entire length of the thorax from the anterior margin ; these neither 

 touch the sides nor the dorsal line. Elytra nearly twice as long as 

 wide, rather wider than the thorax, punctate striate, sides gradually 

 converging to the apex, which is but slightly pointed. Beneath 

 and legs finely punctured, covered with white hairs. 



Length 12 lines, breadth 4|.

Stigmodera affinis. (Plate IX. fig. 4.) 

 Limbata, C. G. nee Donov. 

 Capite thoraceque aereo-viridibus ; thoracis marginibus sanguineis ; 

 elytris punctato-striatis, flavis, sutura late viridi, marginibus sangui- 

 neis ; subtus viridis. 

 This species, so closely allied in general appearance to Limhata 

 of Donovan, may be distinguished in the following manner : — 

 The colour of the head and thorax are bronzy-green, instead of brassy- 

 green, as described and figured by him. The thorax is longer and much
