Udb. — Rockliamptoii, Queensland (Mr. H. Brown). 



A single ^ specimen, generously given to me by its captor, is 

 nearest to P. cyaneus Pasc, and P. ellipticus mihi, in form, but is 

 narrower and more convex than either, and quite different in colour 

 and sculpture. It is distinguished by the contrast of nitid head 

 and pronotum, with its subfuscous elytra, tlie sculpture of the 

 intervals being irregularly and finely striate, like the skin of one's 

 hand. Type in the Author's Coll. 



Opigenia Browni, n.sp. 



Oblong-oval, convex; upper surface green and blue with purple 

 reflections, the suture golden; underside, legs and antennae nitid- 

 black, tarsi wdth a very thin clothing of red tomentum. 



Head: epistoma truncate, angulate wdth the canthus, limiting- 

 suture subobsolete, canthus little raised, eyes separated by a space 

 of the width of one, half concealed by thorax, coarsely and closely 

 punctate, antennae not reaching base of prothorax, joints 3-7 of 

 equal length, 8-9 successively wider and subtriangular, 10 trans- 

 verse, 11 shortly oval. Frothora,v 3(vixjx5mm., widest at 

 middle, wider at base than at apex, the latter circularly emargi- 

 nate, the anterior angles produced, slightly rounded and obtuse, 

 sides widely and evenly rounded, posterior angles rather \videly 

 acute, not dentate; base strongly bisinuate, lateral border moderate, 

 narrowly concave within, apical border very narrow; disc very 

 clearly and rather deeply punctate at sides and base with a large 

 smooth transverse middle space, with no indication of a middle 

 line. Scutellum triangular and punctate. Elytra as wide as pro- 

 thorax at base, widening at shoulders, subparallel on middle third, 

 evenly convex; striate-punctate, the intervals closely punctate, the 

 seriate and interstitial punctures of almost equal size and scarcely 

 differentiated. Prosternum closely rugose-punctate, slightly com- 

 pressed and raised in middle, its process widely rounded behiiid, 

 epipleurse smooth, metasternum smooth in the middle, strongly 

 punctured on sides and epimera; abdomen finely punctate and
