thorax, entirely black, jaws and labrum also black, the anterior 

 edge of the latter emarginate. Thorax more than twice as broad 

 as long ; sides rounded at the extreme base, thence straight and 

 parallel to the apex, anterior angles acute, slightly produced 

 laterally ; surface very finely punctured, disc nearly glabrous, 

 sides sparingly clothed with fine whitish pubescence. Scutellum 

 closely covered with adpressed hairs. Elytra parallel, slightlv 

 attenuated near the apex, sparingly clothed with fulvous hairs, 

 which are more crowded towards the apex, distinctly punctured, 

 the punctures arranged in ill defined longitudinal rows ; rufo- 

 testaceous, a narrow band at the base, an interrupted fascia across 

 the middle, together with an ill defined sul:)-apical patch attached 

 to the outer margin black. Body beneath densely clothed witli 

 adpressed cream coloured hairs. 



Megalostomis coerulea, mihi. 



Oblonga $ , oblong-ovata ^ ; supra metaUico-coerulea, tenuiter 

 pubescens, antennis nigris ; subtus nigro-coerulea, dense albido- 

 tomentosa, abdomine pallide piceo. Long. 3^ lin. 



Hab. Amazons. 



Head near similar in both sexes; vertex tumid; face excavated 

 ]:)etween the eyes, and furnished with three longitudinal ridges, 

 one on the medial line, the others, one on either side, just -within 

 the inner orbit ; the lateral ridges are less regular than the 

 medial, and are rendered still less distinct by a number of 

 irregular, raised vittas ; anterior edge of clypeus shghtly angu- 

 late-emarginate ; whole surface of head sparingly punctured ; 

 antenna? black. Thorax with its basal lobe transversely trun- 

 cate ; sides abruptly diverging at the extreme base, thence 

 converging and very slightly rounded to the apex, anterior and 

 posterior angles acute ; above transversely convex, sub-cylindrical 

 at the apex, chstinctly punctured ; on either side just in front 

 of the middle is a deep obliquely transverse depression ; surface 

 clothed throughout with fine sub-depressed griseous hairs, which 

 are more crowded on either side, and form an ill-defined lateral 

 patch. ScuteUum trigonate, its apex rounded, surface finely 

 but distinctly punctured, covered Avith adpressed hairs. Elytra 

 more closely punctured than the thorax, clothed with similar 

 liairs. Body beneath densely clothed with adpressed whitish 

 pi;bescence, which entirely conceals the colour of the surface. 



Doryphora biiiinata, mihi. 



Oblonga, convexa, piceo-fulva, supra prasina, antennis piceis ; 

 elytris regulariter punctato-striatis, utrisque vitta brevi suturali
