500 NOTES ON THE GENUS STIGMODERA, 



apex, three alternate intervals subcostate at base, the intervals 

 strongly irregularly punctate, presternum rugosely, meso- and 

 metasternum moderately, abdomen very finely punctate, and 

 clothed with fine white hair. Dimensions: 10-11 '5 x 2"5-4 mm. 



Ilab. — VVannei'OO, West Australia(Mr. W. Duboulay). 



Three specimens, including the sexes, under examination. It 

 is near S. ignota Saund., in colour (except in the absence of the 

 lateral vitta, and the underside), in shape like ^S*. cinnamomea 

 Macl. I cannot find any described species very close to it. In 

 one specimen, the single fascia is reduced to two spots on the 

 elytra. Thei'e is a distinct, nai-row, bluish-green band at the 

 base of the elytra, only noticeable from a front view. The shape 

 of the prothorax (widest before the middle) is unusual. Types

Stigmodera seminigra, n.sp. (Plate lii., fig. 8). 



Elongate, narrow, moderately convex; head, pronotum, and 

 sternum bronze-black, the last more brightly bronze; basal border, 

 a large humeral spot, apical two-thii-ds of elytra, scutellum, legs, 

 antennae, and two apical segments of abdomen, black; basal seg- 

 ments of abdomen, and basal portion of elytra (except the humeral 

 spots) yellow. 



Head elongate, narrow, produced in front, excavated longi- 

 tudinally, the concavity bordered by carinse on apical half; closely 

 and strongly punctate. Pronotum strongly gibbous, apex nearly 

 straight, base very sinuate and not much wider than apex, with 

 central lobe almost angularly produced, widest behind the middle, 

 sides strongly rounded, converging gradually forward, rapidly 

 and with strong sinuation behind; anterior angles obtuse, pos- 

 terior acutely produced outward: disc with median line moder- 

 ately distinct, without any smooth area, the whole closely punc- 

 tate, with two lateral depressions near angles, without central or 

 other fuveie. Scutellum triangular, raised at sides, depressed and 

 punctate in middle. Elytra wider than prothorax at base, 

 shoulders prominent and round, sinuately narrowed behind these, 

 slightly enlarging again on posterior third, apex a little open at 

 the suture, finely lunate, with exterior tooth distinct; striate-
