prosternum, by the absence- of the angular notch at the apex 

 of the basal lobe of the thorax, by the larger and differently 

 sliaped scutellum, by the more prominent head, and, lastly, by 

 the elongate form of the body ; from Ochrosopsts and allied 

 genera it is separated by the differently shaped eyes, by the 

 short antennae, by the entirely different form of the prester- 

 num, and by the nearly entire basal lobe of the thorax. 



Tapj}esia Saundersi. 



T. elongata, subparallela, modice convexa, snbnitida, brunnea, piceo 

 variegata, pube squamiformi adpressa flava et albida parce vestita ; 

 antennis pedibusque piceo-fulvis, illarum articulis ultimis quinque 

 apice infuscatis, femoribus piceo tinctis ; thorace crebre ruguloso- 

 punctato ; elytris crebre punctatis, ad latera et ad apicem obso- 

 lete striatim sulcatis.

Hah. Gawler Town, South Australia. 



Headpiceous, swollen on the vertex, closely rugose-punctate; 

 clypeus transverse, bounded on either side by an oblique ridge, 

 its lower portion, together with the labrmn, rufo-piceous : an- 

 tenn£e slender, much less than half the length of the body ; 

 five outer joints very slightly dilated. Thorax twice as broad 

 as long at the base ; sides rounded at the extreme base, thence 

 obliquely converging and rounded to the apex ; basal margin 

 concave and faintly bisinuate on either side, median lobe mo- 

 derately produced, obtusely angulate, its apex truncate, obso- 

 letely sinuate ; upper surface obliquely but slightly depressed 

 on either side behind the middle, closely punctured ; inter- 

 spaces finely rugulose. Scutellum nigro-piceous, scarcely 

 broader than long. Elj^tra oblong, not bi'oader than the 

 thorax, faintly excavated behind the scutellum, closely punc- 

 tured ; towards the apex and on the outer disk of each elytron 

 are a number of faint longitudinal sulcations, which corre- 

 spond to the punctate strife found in most species of Cryj)to- 

 cephalidse : in the present instance they are not more 

 distinctly punctured than the rest of the surface, but their 

 interspaces are slightly convex. 



Ditropidus Wallacei, 



D. breviter ovatus, valde convexus, nitidus, subtus niger, pedibus 

 obscure fulvis, femoribus posticis quatuor piceis; supra metallico- 

 purpureus, labro autennisque fulvis, his extrorsum piceis ; tborace 

 minute subremote punctato ; elytris sat fortiter punctato-striatis, 

 striis sulcatis, interspatiis Isevibus, convexiusculis, iis ad latera 

 convexis.
