fovea. Proihorax with apex nearly straight, base bisinuate. 

 sides rounded and narrowed anteriorly, anterior angles 

 depressed and obtuse, posterior subrectangular. Elytra 

 narrowly subcylindric, acuminate at apex, the sides not ser- 

 rated ; each extremity with a small oblique excision, scarcely 

 spinose; striate-punctate, the seriate punctures small and 

 little evident, the intervals flat on disc, convex near apex, 

 and almost smooth. Sternum finely, abdomen minutely 

 punctate, with rather close, whitish pubescence. Dim., 

 9-11 x 3-4 mm. 



Hub. — Western Australia: Cue (H. W. Brown). 



A small species, evidently very near but apparently not 

 mansueta, Kerr. ; also near xanthopilosa, Hope. The colour 

 does not tally with the description of the former, the pro- 

 thorax being blue (not green) and not "sillonne longitudinale- 

 ment." The elytral markings also are red (not yellow), while 

 Kerremans says of his species, "Mains acumine an som-met 

 et vn pen plus large que S. elongatula, Macl." In my 

 species the apex is considerably more acuminate than in 

 elongatula. Types in the author's collection. 



Stigmodera octocostata, n. sp. 

 PI. x., fig. 27. 



d . Elongate-subcylindric. Head, antennae, and elytra 

 uniform blue-black, pronotum yellow with three black mark- 

 ings, the first medial club-shaped, the oval club occupying the 

 front part, with a straight stem exactly filling the wide medial 

 sulcus on basal half, the other two dumb-bell shaped, 

 symmetrically placed on each side of the middle, the basal 

 ball of dumb-bell exactly occupying a round basal depression 

 near the hind angles ; prosternum yellow with a black basal 

 border extending forward on each side; rest of underside and 

 legs a rich dark-blue, quite glabrous. 



Head excavated between the eyes, closely punctate. 

 ProtJiorax convex, widest at middle, sides evenly and rather 

 widely rounded, nearly straight at apex and base, a little 

 wider at base than at apex, all angles obtuse; disc with wide 

 central depression on basal half and two large depressed 

 foveae at sides; densely and evenly punctate. Scutellum 

 widely triangular, depressed, and punctate. Elytra strongly 

 widened at shoulders, then subparallel to near apex, there 

 each elytron very finely bispinose; base irregular, each elytron 

 angulately produced forward at the middle, the angle being 

 formed by the short scutellary costa meeting the raised 

 humeral margin and overlapping the base of prothorax ; disc 

 with three well-raised costae, the first pair meeting within 

 the basal angle and continuous to the apex, terminating there
