and Species 0/ Heteromera. 103 



abruptly elevated between the coxaj, a little concave in front 

 of tliem, the extreme anterior portion always distinctly hori- 

 zontal : prothorax very convex, slightly but distinctly rounded 

 at the sides, lobed at the middle of the base, and very strongly 

 and deeply punctured : lateral retlexed margins of the elytra 

 distinctly continued along the basal margin up to the scutellum: 

 the punctuation of the surface more or less irregular, Avith the 

 interstices more or less strongly, ti-ansversely, and reticulately 

 rugose 5 and the body is ordinarily distinctly pilose. 



Titcena columhina^ Erichson. 



The colour in this species varies from purple to green, the 

 front margin of prothorax and sutural edging of elytra being 

 ordinarily of some shade of green ; sometimes, however, it is 

 coppery, golden, greenish cyaneous, &c. ; the reflexed lateral 

 margins are generally (except at the apex) of the same colour 

 as the sides of the elytra ; the legs are of a more or less dark 

 piceous, sometimes with a green tinge. The head and prothorax 

 are more or less closely covered with deep punctures, the latter 

 slightly but distinctly rounded at the sides ; the elytra are 

 rather strongly punctured, with a disposition to a seriate 

 arrangement ; the intervals distinctly transversely and some- 

 what reticulately rugose ; and the body is distinctly pilose.

Hah. Australia; generally distributed. Eight examples 

 in my collection. 



Var. ? virida. 



Smaller (4 g lines). Head and prothorax bronzed green: 

 elytra dark green, without distinct sutural edging, except 

 slightly towards the apex : underside and legs piceous : 

 flanks and sides of abdomen covered with large, round, deep 

 punctures : prothorax distinctly broadest in front ; the angles 

 very distinct, slightly produced ; sides distinctly and slightly 

 curvedly narrowed from before the middle to the hind angles ; 

 median basal lobe more produced behind, and the punctuation 

 more regular. 



Hah. Melbourne. One example. 



Titcena pidchra^ n. sp. 



Near T. columhina. Very thinly pilose : head broadly 

 rounded in front ; epistoma short, convex, and, together with 

 the antennary orbits, pitchy red, the suture moderately im- 

 pressed ; rest of the head and the prothorax bronzed green, 

 the punctuation as in T. columhina : elytra dark bronzed green, 

 the base and sides (partly) golden green ; the sutm-e with a
