Rhyparida medionigra, n. sp. 

 PI. vi., fig. 38. 



Black; head (a conspicuous median spot excepted), elytra 

 (wholly or "in part), and part of abdomen more or less reddish, 

 appendages paler. 



Head with moderately dense but not very large punctures, 

 becoming larger and more crowded on clypeus; with a short 

 medio-fi^ontal impression. Eyes rather widely separated. 

 Prothora.r at base scarcely once and one-fourth the median 

 length, sides rather strongly rounded, and widest nearer base 

 than apex, front angles unarmed : with fairly dense but rather 

 small punctures, becoming larger and denser on sides. Elytra 

 distinctly wider than prothorax, sides parallel for about half 

 their length, or very feebly dilated to beyond the middle ; with 

 rows of rather small punctures, becoming smaller posteriorly, 

 and absent from apical slope. Flanks of jjrosfeniinn striated 

 throughout. Femora minutely dentate ; claws bifid. Length, 

 3f-4 mm. 



7/^/5. _South Australia: Leigh Creek (Blackburn's col- 

 lection). Mount Painter (near Leigh Creek) (H. G. Stokes). 

 Type, I. 3059. 



Closely allied to ajjicalis, but eyes more widely separated, 

 and head more convex about base. From mai/ae it is readily 

 distinguished by the elytral punctures almost disappearing 

 postermrly, and head with a medio-basal carina. ^5i) The three 

 specimens before me vary somewhat in colour. On the type 

 each elytron has a large blackish blotch (becoming paler m 

 places) 'connected with the side (this narrowly black through- 

 out) at the summit of the apical slope. A specimen (associated 

 with the type in the Blackburn collection) has the base and 

 apex of prothorax reddish, and the elytra almost entirely red- 

 dish, becoming paler posteriorly, but with the suture^ and 

 sides feebly infuscated! The specimen from Mount Painter 

 is without p cephalic spot, the prothorax is reddish (vaguely 

 infuscated towards each side), and the elytra are mostly 

 flavous, becoming darker towards base and suture, and with 

 a vaguely-defined infuscate spot on the basal half towards each 

 side. 



. Rhyparida flavipennis, n. sp. 



Dark reddish-brown; elytra (suture and sides excepted), 

 legs, and antennae (the apical joints more or less infuscated) 

 flavous. 



(51) No doubt on specimens with the base of the head partially 

 concealed the carina would be covered: but of both species there- 

 are specimens before me with the base of the head not concealed.
