862 ON THE GENUS NASCIO, 



one on each side of the middle, and a third much smaller one in 

 the middle at the base ; the anterior margin slightly produced 

 in the middle ; the sides somewhat narrowed in front, slightly 

 constricted near the posterior angles which are acute and projecting ; 

 the basal margin nearly straight. Scutellum small, slightly 

 concave. Elytra broader than the prothorax at the base, strongly 

 and closely punctate-striate, the striae impressed at the base, the 

 interstices moderately broad and strongly punctured, with two 

 yellow fasciae one before the other considerably behind the middle 

 extending from the sides to just before the suture ; these fasciae 

 are rather broad at the sides, and gradually decrease in width as 

 they approach the suture. Underside bronzy, somewhat shining ; 

 sterna rather closely and strongly punctured ; abdominal segments 

 less strongly punctured. Legs distinctly punctured. Length, 

 11-13 mm. 



Rope's Creek, New South Wales; Salt Eiver, West Australia. 



Three specimens of what I take to be the female of the insect 

 described above have a much broader and more convex prothorax 

 without the two discal impressions, the median line on the head 

 very indistinct, and the apex of the elytra rounded and not 

 provided with spines. 



Avery distinct species which is, perhaps, best placed between 

 Nascio simillima and N. xanihura. 



Nascio munda, sp. n. 



Elongate, metallic green, shining, with purplish reflections, 

 moderately narrowed behind ; the head and prothorax rather dull 

 coppery, the latter purplish in the middle; the underside bright 

 coppery ; the apex of the elytra provided with inconspicuous 

 spines. 



Head strongly and closely punctured, coppery in front, purplish 

 between the eyes at the base. Prothorax slightly convex, 

 narrowed in front, strongly and closely punctured, with a small 

 foveolate impression in the middle at the base ; the anterior margin
