206 Arthur M. Lea: 



Head and 2>rothorax with small dense punctures. Elytra with 

 slightlj- larger and sparser punctures, interspersed with numer- 

 ous larger (but still small) punctures. Under surface with 

 sparse and small punctures, beco-ming very dense at sides. Inter- 

 coxal process of presternum moderately convex, carinaite at apex 

 but not at sides. Lamellaie extending to about one-fifth from 

 suture. Length, 3^ — 3-| mm. 



Also from Tasmania (Hobart). 



A greatly depressed species apparently close to aurantii, but 

 the prosternum convex instead of concan-e along the middle, and 

 apparently with smaller jjunctures, those on the elytra being 

 decidedly smaller and denser than on discolor, and uneven in 

 places; the punctures on the prothorax are rather denser than 

 on the elytra and are decidedly small. 



The pale portion at the apex of the prothorax is very narrow; 

 on each elytron it commences ait the base, close to but not on 

 the margin itself,' and dilates till it becomes marginal, and still 

 dilaites till it occupies about one-third of tlie apex. On one 

 specimen, however, it commences behind the middle and be- 

 comes marginal only near the apex. On the elytra the 

 pubescence is somewhat sinuously disposed in places, and on 

 abrasion very faint traces, as of striation, become visible.

Black, elytra with a coppery gloss ; head, apex and sides of 

 prothorax, apex of abdomen, tarsi, tibiae (the four hind ones 

 somewhat infuscated), knees, trochanters, antennae and palpi 

 reddish. Moderately clothed with rather long, whitish, curved 

 pubescence, interspersed Avith suberect fine brownish setae. 



Upper surfaice with small punctmTS of even size, but denser 

 on head than on prothorax, and on prothorax tli '.n on elytra. 

 Intercoxal })rocess of prosteriiuni flat, sides scarcely cai'inated. 

 Metasternum and abdomen with small and spaa-se punctures in 

 middle, becoming dense at sides ; lamellae extending to about 

 one-fourth from suture. Length, 2 mm. 



Close to lindi, but smaller and darker, i)ubesccncc lunger and 

 seta.e shorter and sparser. From plebejus (except that it is 



1 Oil one spec-imen, however, it. is iiiartjinal at the base.
