1(J4 THE CARABIDAE OF TASMANIA, 



rounded on sides; eljira more strongly striate, interstices convex; there are, how- 

 ever, iu the Simsou Coll. specimens which link this slightly diflferentiated race 

 with the typical foi-m of the species; one would need to be more confident of the 

 value of these apparent differences than I am to give a distinctive name to No. 

 3693 of the Simson Coll.

Table of Tasmanian species. 



1 (4) Prothorax sinuate, or subsinuate before basal angles, these marked. 



2 (3) Elytra with all striae distinctly marked, interstices convex at apex 



(seventh stria faint or obsolete for two thirds of its length). 

 Length, 10—12 mm iiiiser Chaud. 



3 (2) Elvtra with five inner striae well marked, sixth and seventh faint or 



obsolete, except near apex. Length, 15 — 17 m.m. liopkiinis Chaud. 



4 (1) Prothorax with sides arcuate to base, basal angles not marked. ( Four 



inner striae wsll marked, striae 5 — 7 faint or obsolete, except to- 

 wards apex.) Length, 14 — 17 mm na//ioderus ChavtA. 



All these species are common and widely spread on the Australian mainland; 

 only R. cijathoderus (No. 2476) was in the Simson Coll. The others are included 

 here on the authority of Jlr. Lea's "List" of :i.)02.

Genus H M T ii E s. 

 I now consider this genus to belong to tlic tribe Anchomenini, which is the 

 position assigned to it by Erichson. It is certainly not a Lebiid, the anterior coxal 

 cavities liaving a single o])cning inwards; the tarsal vesture of tlie c? is as in the 

 .Vnchtimenini, not as in the Odacanthini.
