BY THE REV. T. BLACKBURN. 323 



The glossy shining scales closely adpressed and evenly covering 

 the derm give this species a slightly metallic aspect. On the 

 prothorax the paler scales are confined to the sides and a slender 

 line down the middle, on the elytra they are conspicuously condensed 

 on each shoulder and rather evenly scattered in small inconspicuous 

 blotches over the rest of the surface. The present species comes 

 nearest to D. nigra but (apart from colour and markings) is a little 

 less narrowed behind with the elytral interstices scarcely at all 

 convex, and bearing a very distinct (though by no means strong) 

 nodosity* where the 5th and 6th interstices unite behind. The 

 elytra are infinitely more closely scaled than in any specimen I 

 have seen of either of the preceding species. 



S.A., near Morgan on the river Murray; a single specimen 

 resting on the trunk of a tree. 



Desiantha maculata, sp.nov. 



Oblonga ; nigra, antennis (clava excepta) tibiis tarsisque 

 rufescentibus ; squamis albidis ochraceis et nigris dense macu- 

 latim vestita et spatiis parvis nudis sparsim variegata ; rostro 

 minus elongato, minus nitido ; prothorace oblongo ad latera 

 fortiter rotundato, Isete aibido-tri-vittato, confertim subtilius 

 rugulose punctulato et granulato ; elytris punctulato-striatis, 

 puncturis sat magnis quadratis, interstitiis subcarinatis qui- 

 busdam elevatioribus, setulis suberectis ornatis, interstitiis 

 5° 6°que postice conjunctis leviter nodulosis. 



[Long. 3, lat. \\ lines (vix). 

 On the forehead there is quite a tuft of pale hair-like scales ; 

 those placed transversely all down the surface of the rostrum 

 (which is equal to the prothorax in length) are plentiful and con 

 spicuous : the prothorax bears white scales in two or thi'ee sinuous 

 j-ather conspicuous lines on the sides and in a very narrow straight 

 line down the middle ; on the elytra the ochreous scales are con- 

 densed along the suture, on the sides they are rather evenly mixed 

 in among tho.seof a whitish colour and tliey also .somewhat obscurely 



* This nodosity is very much less marked than in tlie insect mentioned 

 above as agreeing specifically with the description of Brexius murinus, Pasc.
