POLYSTIGMA CALOPYGA, n. Sp. 



PI. vi., fig. 6; pi. xiii., fig. 184. 

 <3 . Head black ; clypeus flavous, with two conspicuous 

 black stripes; prothorax black, the margins (but neither the 

 extreme base nor apex) rather narrowly flavous ; scutellum 

 flavous, the base partly black; elytra flavous, suture and sides, 

 a large spot on each side of scutellum, a submedian fascia 

 (connected with suture and sides), a large subapical angular 

 spot on each (narrowly connected with suture), and the 

 shoulders black ; pygidium flavous, base and apex red, and 

 three or five spots black, but red where joined to the basal 

 and apical red. Under-surf ace reddish, in parts black ; parts 

 of hind coxae, and of sterna, and the mesosternal process 

 flavous; appendages more or less red, the hind tarsi almost 

 black. Under-surface densely clothed in parts with whitish 

 hair. 



Head with fairly dense punctures. Clypeus subcordate, 

 apex moderately notched, tips rounded, near sides vaguely de- 

 pressed ; punctures rather denser than on head. Club almost 

 the width of base of clypeus. Prothorax rather strongly nar- 

 rowed from base to apex, margins rather strong, sides lightly 

 bisinuate, medio-basal sinus rather strong, about two-thirds 

 the width of each of the lateral ones ; disc with small and 

 sparse punctures, becoming denser and in places strigose on 

 sides. Scutellum, with a few small basal punctures. Elytra 

 with prominent shoulders, posthumeral incurvature strong, 

 base with several narrow striae, one of which on each side is 

 continued past the scutellum, and becomes the sutural stria; 

 with small punctures in feeble rows, apex and sides from about 

 the middle transversely or obliquely strigose. Pygidium 

 densely, concentrically strigose. Abdomen gently incurved 

 to middle from base and apex, vaguely depressed along middle. 

 Mesosternal process rather acutely produced and curved in 

 front. Legs long, front tibiae strongly dentate at apex only, 

 hind pair with a transverse ridge slightly nearer apex than 

 base. Length, 13-13^ mm. 



Hah. — Australia (National Museum, Melbourne, from 

 C. French); Queensland: Oooktown (Blackburn's collection). 

 Type, I. 1482, in South Australian Museum. 



The type bore a label in the late Rev. T. Blackburn's 

 writing, u Eu'pcecila? ,, Its mesosternal process, abdomen, and 

 legs, however, are more in agreement with those of Polystigma, 

 from all the described species of which it is very different in 

 its markings. These are all connected together on the elytra, 

 but the suture and shoulders in places appear to be diluted 

 with red. When viewed obliquely from above the pygidium 

 appears to have a conspicuous flavous V, the black median
