-563. — Hyocis pubescens. n. sp. 



Length Ij lines. 

 This species diflFers from the last in its very distinct 

 kind of pubescence, which is rather long, decumbent, and of a 

 white colour. It differs also in having the head of a brassy 

 black and without impressions, in having the thorax with the 

 anterior angles advanced, and two longitudinal foveae at the base, 

 in having the scutellum triangular, and in having the elytra less 

 nitid and marked with a few brown spots. 



564. — Mtchestes Pascoei. n. sp. 

 Length 4 lines. 

 Black, opaque, tuberculose, granulose and densely covered 

 with brownish yellow scales. Head foveolate in front, with the 

 suture of the clypeus semicircular, the parts of the mouth nitid, 

 and the labi'um emarginate. Thorax subtransverse, emarginate 

 in front, truncate behind, much bulged out and abruptly rounded 

 on the sides and elevated on the disk into a large laterally com- 

 pressed rounded tubercle which projects over the head and 

 which extends itself backwards in a triangular form nearly to the 

 base of the thorax where it terminates in an obtuse tubercle. Scu- 

 tellum nearly round. Elytra convex, scarcely longer than the 

 widtli at the base, of the same size as the base of the thorax and 

 fitting closely to it, swelling out in the middle to the size of 

 the thorax at its broadest part, subacuminate and perpendicular 

 towards the apex, and rough on the surface, with large depressions 

 and obtuse tubercles, the most elevated being a three headed 

 tubercle near the base on each side and some distance from the 

 suture. 



565. — Mychestes Mastersii. n. sp. 

 Length 4 lines. 

 Oblong-oval, black, opaque, rough, rugosely tuberculate, and 

 densely covered with dark brown scales. Thorax truncate at the 

 base, broadly marked on the median line, and advanced in front 

 into a round rough projection constricted behind which entirely 

 covers the head, and looks from above exactly like a head and
