68 ON THE SCARITID.E OF NEW HOLLAND, 



Count de Castelnau has formed the genus Neocarenum, that for 

 the present I will refer them to that genus. 



Neocarenum Mastersi. 



Nigrum subnitidum sulcis frontalibus divergentibus postice 

 profunda antice leviter impressis, thorace elongato postice 

 rotundato, elytris elongatis seriatim profunde punctatis ; 

 tibiis anticis extus bidentatis. 

 Long. 17 lin., lat. 4 lin. 

 Hab., Mount Barker, "Western Australia. 

 The enormous size and remarkably elongated form of this 

 insect separates it at once from all others of the Scaritidce known 

 to me. The marking also of the elytra is unusual. There are 

 nine rows of punctures on each elytron, those towards the sides 

 are almost obsolete, but the five rows on each side of the suture 

 are composed of close, large, deep punctvires. The fore legs are 

 very strong. 



Neocarenum rugosulum. 



Nigrum subopacum elongatnm capite leviter bisulcato, thorace 

 subnitido postice subrotundato linea dorsali leviter impressa, 

 elytris angustis ad suturam depressis leviter striatis, tibiis 

 anticis extus bidentatis. 

 Long. 8 lin., lat. 2 lin. 



Hab., Salt Lake, Hummock Range, South Australia. 

 I I'eceived a single and imperfect specimen of this curious 

 insect, from Mr. Odewahn, a few days ago. The whole upper 

 surface, the thorax excepted, has a slightly rugose appearance, 

 the striee on the elytra, though slight, are distinct, and of a wavy 

 character. The sutural portion of the elytra is deeply indented. 

 There is a well defined punctiform impression on the apical 

 portion of the left elytron, but I cannot find any trace of a similar 

 impression on the other. 



Genus Carenidium, Chaudoir. 



Frons profunde bisulcata ; clijpeus ad labri latera utrinque 

 longius dentatus convexus valde declivis, inter dentes pro-
