826 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES, 



on the segment as a scarcely deBnecl cai'ina, the intervening space 

 being flattened. The base of the femora is sculptured as in the 

 following species, but the part so sculptured being unicolorous with 

 the rest of the surface, is less noticeable. 



Two Australian species of Berosus with elytra apically 

 emarginate have been previously described, Australice, Muls., and 

 externespinosus, Fairm. B. niajusculus differs inter alia from the 

 former of these by the strite and puncturation of its elytra being 

 even over the whole surface (or perhaps slightly stronger near the 

 apex), from the latter by the equality of the apical points of the 

 elytra (which, however, may be a variable character) and by its 

 unicolorous legs. 



Widely distributed in South Australia ; I have seen specimens 

 from Port Lincoln, Adelaide, and Sedan. 



B. GRAVIS, sp.nov. 



Oblongo-ovatns; convexus; supra testaceus; palpis apioe summo, 

 capite postice piotlioracis disco, et elytris, plus minus fusco- 

 nigro-notatis ; subtus (capite, et prosterni lateribus, pallidis 

 exceptis) piceus vel nigro-fuscus ; capite antice sparsius subtilius 

 postice gradatim crebrius fortius, prothorace fortius etiam sparsius, 

 piinctulatis ; elytris apice emarginatis, punctulato-striatis, inter- 

 stitiis planis subtilius nee crebre punctulatis ; pedibus testaceis 

 femoribus 4 posterioribus basi nigris.

This tine large species is closely allied to B. niajusculus from 

 which it scarcely differs in the color and markings of the upper 

 surface. On the underside its entirely testaceous head and the 

 four hinder femora nearly black in their basal two-thirds dis- 

 tinguish it. In respect of sculpture the front part of the head is 

 much more finely punctured than in B. majusculus, the remainder 

 of tlie sculptui'e presenting little distinction. The head is pro- 

 portionately much narrower and more elongate. In the male the 

 dilated joints of the anterior tarsi are much wider, and the surface
