S. convexa, Cart. — In my description of this I stated of 

 the elytra, "Margins entire to apex." There is, however, a 

 minute denticulation quite close to the apex, which I over- 

 looked. 



Stigmodera pisciformis, n. sp. 

 PI. x., fig. 20. 



c 7 . Ovate, much attenuated behind. Head dark-bronze, 

 prothorax, scutellum, and underside dark-blue with bronzy 

 reflections, antennae and legs blue, elytra red, with the base, 

 .two straight fasciae (the first antemedian, not extending to the 

 sides, branching at the suture to the base, the second post- 

 median extending the full width and slightly widened at the 

 middle), and the apical tenth blue-black, the apical macula 

 with straight anterior margin. 



Head deeply excavated, widely channelled, punctate and 

 pubescent. Prothorax very convex, widest (subangulately 

 widened) a little in front of base, thence rather straightly 

 narrowing to apex, apex arcuate, base bisinuate and less than 

 twice as wide as apex, medial lobe wide, anterior angles 

 slightly produced and acute, posterior obtuse ; disc rather 

 strongly punctate, the punctures round and close, subconfluent 

 at the sides, medial line smooth. Scutellum subcordate, 

 concave, laevigate. Elytra depressed, of same width as pro- 

 thorax at base, widened behind shoulders, lightly sinuate at 

 middle, apical third strongly narrowed, denticulate at 

 margins, the apex of each elytron with strong oblique luna- 

 tion and bispinose, exterior spine prominent; striate-punctate, 

 intervals flat or nearly so throughout, distinctly but sparsely 

 punctate. Sternum coarsely, abdomen finely and densely 

 punctate, almost glabrous. 



9 . Differing only in colour from the male. Pronotum 

 and underside with bronzy tints prevailing over the cyaneous, 

 the antemedian fascia only represented by humeral spots and 

 an enlarged sutural macula, the post medial fascia absent. 

 Dim., 15 x 5 mm.

Three specimens examined are the only examples I have 

 seen. It is not, therefore, possible to state that the above 

 coloration is a constant sexual difference, but I am convinced 

 that the three examples are conspeciflc. The form of both 

 prothorax and elytra is unusual, the former abruptly widened 

 near the base, the latter strongly attenuated and spinose. 

 The nearest to it in general form are confinis, Kerr., and 

 thomson/, Saund., but differs from the latter, besides mark- 

 ings in less sinuate and more attenuated form, and its flat 

 and distinctly punctate elytral intervals.
