DERMESTES. 



D. ausfralis, Macl. Judged by the description this name may 

 be confidently regarded as a synonym of the introduced 

 D. vulpinus, Fabr. There seems to be no sufficient evidence of 

 the occurrence of Bermesfes in Australia except by accidental 

 importation. I am not aware of this synonymy having been 

 previously reported. 



BRACHYSPHYRUS (gen. nov.). 



Caput ocello instructum ; palpi maxillares subcylindrici, articulo 

 apicali quam prajcedens sat longiori ; antennae breves, 11- 

 articulataj, articulis 1" 2" que subglobosis quam sequentes 

 multo majoribus 3"— 8° minutis 9'' — 11'^ (exempli typici) 

 clavam formantibus (hac quam articuli ceteri conjuncti vix 

 breviori, articulis 9° 10° que fortiter transversis, IP quam 

 Qus iQus qyg conjuncti vix breviori); oculi modici ovales ; 

 prothorax antice angustatus, postice lobatus ; elytra postice 

 singulatim rotundata, pygidium haud tegentia ; presternum 

 medium carina longitudinali integra instructum, utrinque 

 lon»e intra marginem lateralem fovea sat magna impressum ; 

 mesosternum latum antice processum prosternalem recipiens; 

 femora lata subtus sulcata ; tibiae compressae latse extus 

 spinulis parvis validis cilialae; tarsi modici, articu]o basali 

 minuto quam 2''' multo breviori ; coxae anticae permagnae, 

 prosterni marginem anteriorem fere attingentes ; corpus 

 pubescens. 

 The very large front coxae, the position of the prosternal im- 

 pressions (widely separated from the lateral margins of the seg- 

 ment), the very wide femora and tibi« and the very small basal 

 joints, are all unusual characters in the Dermestidcs. The narrow 

 subcariniform interspace between the front coxae is of similar 

 structure to the same part in Trogoderma, kc, but the coxfe 

 themselves nearly reaching the front margin of the segment, it 

 also is similarly prolonged. 



B. irroratus, sp. nov. Latissimus, fere subcircularis ; subnitidus ; 



nigro-piceus pube subtili minus perspicua fulva vestitus et 



maculis numerosis (his e pilis longioribus niveis formatis) 



irroratus, antennis pedibusque ferrugineis; supra crebre sub- 



tilius punctulatus; subtus pilis sat longis castaneis crebre 



vestitus. Long, HI.; lat., 1 1. 



The structural characters have been so fully specified above in 



the diagnosis of the genus that it seems unnecessary to repeat 



them here.
