5. Encara Lacordairei, n. sp. 



Testaceous-brown, nitid, broadly ovate, the margins of the 

 thorax and elytra of a paler hue. Head like that of E. suh- 

 maculatum but not sunk so deeply in the thorax ; thorax dark 

 brown on the disk, slightly uneven on the surface, and not or 

 scarcely sinuate on the base. The scutellum and base of thorax 

 carinate. Elytra flat, coarsely and densely punctate, rounded 

 behind, the surface rather uneven, suture slightly elevated, three 

 costee more or less of a dark brown colour on each elytron, the one 

 next the suture most distinct and very crooked, the next scai'cely 

 traceable except towards the apex ; the third very indistinct, and 

 joined to the mai-gins behind the middle by a wavy brown fascia ; 

 the humeral callus is also brown. The undersurface and legs are 

 of a nitid brown, minutely punctate and pubescent. 



Long. 5^ lines, lat. 4| lines. 



Rah. — Coast districts New South Wales. 



This is a much rarer species than E. submaculatum. Mr. Masters 

 has never observed it except in the Illawarra district, where it is 

 found like the last species on the sunny side of trees. 



Genus Pterohel^us, De Breme. 



Head immersed in the thorax up to the insertion of the antennfe, 

 slightly narrowed and broadly truncate or sinuate in front. Eyes 

 more or less prolonged in front but not contiguous. 



Antennae as long or a little longer than the thorax, their four 

 or five last joints nearly orbicular and forming an inconspicuous 

 mass. Thorax very strongly transversal, parabolically rounded 

 on the sides, broadly and strongly emarginate in front, contiguous 

 to the elytra, and slightly bisinuate at the base, its foliaceous 

 part moderately broad aiid flat. Elytra large, moderately convex, 

 sometimes oblong, sometimes broadly oval, and in the first of these 

 cases the foliaceous mai'gin is narrow and raised ; in the second it 

 is large, as in the thorax. Legs long ; tibiae smooth, aciculate ; 

 one spur on the anterior and two very small ones on the four
