M. illota, Pasc, the present species is less opaque, its prothorax 

 is less narrowed behind, and its antennae are longer, more slender, 

 and less incrassate towards the apex, with the apical two joints 

 distinctly though not much shorter than the preceding joints ; 

 the last joint of the maxillary palpi is a little more sharply tri- 

 angular than in M. iUota. 



South Australia ; near Port Lincoln, under bark.

 This genus is remarkably like Ditoma superficially, but may be 

 at once distinguished by the 3-jointed club of its antenna3. A 

 species occurring not uncommonly in S. Australia and Victoria 

 agrees very well with the description of S. iriterricptus, Er., the 

 only species named up to the present time. The following seem 

 to he new : —

S. po'oxhmts, sp. no^'. Opacus ; niger, capite antice antennis 

 pedibusque rufescentibus ; supra granulatus ; caj)ite fere ut

 Very like S. interricptiis, Er., but differently coloured and 

 sculptured, the upper surface (except the reddish front of the 

 head) being unicolorous ; the inner two costse on each elytron 

 being less frequently, and less widely, interrupted (so that they 

 appear mucli less like a series of tubercles) ;. and the hinder of 

 the two angles of the sides of the head being quite rounded off. 

 In both these species the upper surface of the head is flattish and
