72 NOTES ON AUSTRALIAN COLEOPTERA, 



prothorax of S: posticalis is not a little more narrowed in front 

 than that of typical S. corticalis, but the character is certainly too 

 slight to be regarded as specific. The prothorax of the male in 

 both forms is a little less transverse than of the female and seems 

 to be at its widest slightly nearer to the front ; and the male has 

 a slight excision at the end of the apical ventral segment. The 

 above remarks are founded on the examination of a fairly long 

 series from S. Australia, Victoria, and Tasmania. 



Sarothbocrepis (Lebia) calida, Newm, 

 I believe this species to be identical with S. corticalis, Fab. 



ECTROMA OBSOLETUM, Sp.nov. 



Oblongum, postice latius ; testaceum, elytvis a basi retrorsum 

 indeterminate fusco-3-vittatis, vittis postice ad fasciam sub- 

 obsoletam subapicalem fuscam attingentibus, corpore subtus 

 fusco-adumbrato ; antennarum articulo basali 3° longitudine 

 ajquali ; prothorace sat transverso, antice subtruncato quam 

 postice parum angustiori, lateribus parum arcuatis postice 

 vix sinuatis, angulis posticis fere rectis (apice summo subro- 

 tundato) ; elytris striatis, striis obscure punctulatis. 



[Long. 3, lat. l^Sj- lines. 

 I have no doubt this species is congeneric with E. civicum, 

 Newm., but as my example is a female there remains a possibility 

 that the discovery of the male might prove it to be a Sarothrocrepis. 

 In colour and markings it is not unlike a washed-out specimen of 

 Sarathrocrepis corticalis, Fab., but is smaller than any example I 

 have seen of that species, has the basal joint of the antennse 

 longer, the prothorax of quite a different shape, &c., while its 

 general form is much more elongate, with the elytra gently wider 

 from the base nearly to the apex and with their lateral margins 

 nearly straight. In respect of most of the above mentioned 

 characters it agrees with the insect mentioned below, which I 

 take to be E. (Lebia) henejicum, Newm., but differs from it by its 

 more robust form, longer and stouter legs, less strongly transverse
