noticeably greater than is usual in the genus ; the middle lobe of 

 the " trilobed outline " of the head is scarcely so much longer 

 than the lateral lobes ; the front of the clypeus is evidently decli- 

 vous ; the prothorax is not so transverse being not quite three 

 quarters again as wide as long, the base being gently but almost 

 evenly and continuously convex hindward, the middle however pre- 

 senting on careful inspection a very slight sinuation or concavity ; 

 the elytra are evidently wrinkled transversely ; the under surface 

 is nitid and moderately strongly but not closely punctured (much 

 more coarsely and sparsely than in the species of the jmstidosus 

 type), the hind coxaB having a small but distinct antero-internal 

 laevigate space. The ventral series consist of hairs and are not 

 very conspicuous. The entire puncturation of the upper surface 

 is very manifestly stronger, coarser, and less close ; that of the elytra 

 being coarser than, and that of the prothorax very similar to, the 

 same in H. flavus. The present species also resembles H. flavus, 

 but it is more nitid and of a decidedly ferruginous tone of colour, 

 with the clypeus wide in front as well as with the elytra differ- 

 ently punctured as just noted. The elytra have the suture some- 

 what elevated, and becoming keel-like near the apex, the ajjex 

 itself being prominent, almost spiniform. 



S.A. ; I have seen it only from the Adelaide district.

H. longulo valde affinis ; differt prothorace ad latera minus 

 rotundato, lateribus basin versus minus convergentibus, augulis 

 posticis (superne visis) sat minus rotundatis ; elytris minus fortiter 

 punctulatis, sutura minus convexa apicem versus hand carinata, 

 apice suturali nullo modo spiniformi. [Long. 4 J, lat. 2 lines. 



So extremely close to //. longidus that it would be useless to 

 repeat the Latin diagnosis in fidl, but I am convinced that it repre- 

 sents a distinct species. I do not observe any differences beyond 

 those mentioned above except that the two examples before me 

 are a trifle larger than any B. longidus I have seen, and of a some-
