506 NOTES ON THE GENUS STIGMODERA, 



Elytra of same width as prothorax at base, rather strongly widen- 

 ing at shoulders and more strongly again behind the middle, 

 posterior sides very minutely serrated, striate-punctate, intervals 

 convex, closely punctate; apex obliquely lunate, each elytron 

 bispinose. Sternum coarsely, abdomen finely and closely punc- 

 tate, and clothed with white hair. Dimensions : 9 x 3-5 mm. 



Hah. — Kuranda, North Queensland(Mr. F. Dodd). 



A single ^ specimen is unlike any described Stigmodera of 

 which I am aware. The pattern is nearest that of *S'. biyuttata 

 Macl., but it is a much smaller insect, and differs widely in shape. 

 The single fascia is nearly straight in front, curved on the pos- 

 terior margin, and suddenly narrowed at the sides; the apical 

 spot has its front margin straight, the space of about ^ mm. from 

 the apex being covered. Type in the author's coll. 



Stigmodera convexa, n.sp. (Plate Hi., fig. 2). 



Cylindric ; head, pronotum, scutellum, antennae, legs, and 

 underside dark coppery-bronze, nitid ; beneath densely 

 clothed with white hair ; elytra diill orange-yellow, with an 

 oval spot behind the shoulder, a round common sutural spot 

 between the former, an undulate postmedian fascia, and a 

 preapical spot shaped like the ace of spades, black ; the 

 sutural spot, fascia, and preapical spot more or less con- 

 nected on the suture ; the apex itself tinged with red. 



Head excavated, not canaliculate, and with the pronotum 

 having coarse, closely placed jjunctures. Pronotum sub- 

 gibbous, apex nearly straight, base sinuate ; measurements 

 of apex, base, and length, 2),, 4, 3 mm. respectively ; a strong 

 medial depressed line throughout (accentuating the sub- 

 bilobed convexity), sides widely rounded, greatest width be- 

 hind middle, slightly sinuate anteriorly, all angles obtuse, 

 baso-central fovea small, without any basal excision. Scutel- 

 lum cordiform, large, depressed, impunctate. Elytra of same 

 width as prothorax at base, very little enlarged at shoulders 

 or behind middle, very convex, margins entire to apex, the 

 latter in o* without any excision or spine, in 9 somewhat
