 surface. 



Hah. Ferguson Island (Meek). 



This species resembles in shape /?. discopundulata Blackb. on 

 accounl of the short transverse thorax which is not wider at the 

 base than the elytra, the impunctate head, finely punctured clypeus 

 and the sculpture of the elytra will further assist in the récognition 

 of the species. 



Rhyparida melanocephala n. sp. — Black, the antennœ and 

 the thorax dark fulvous, the latter nearly impunctate, elytra with 

 basai dépression, rather finely punctate-striate, the apex nearly 

 impunctate, legs unarmed. — Length, 6-7 mill. 



Hoad black, very finely and sparingly punctured at the vertex, 

 the latter distinclly separated at its lower portion from the clypeus 

 which is of subquadrate shape and nearly impunctate, labrum dark 

 fulvous; antennae with the lower seven joints fulvous, the rest 

 blackish; thorax about one half broader than long^ the sides stron- 

 gly rounded, the surface rather convex, extremely minutely 

 punctate, only visible under a strong lens; scutellum piceous; 

 elytra wider at the base than the thorax, with a distinct dépression 

 below the base, black, rather finely punctate-striate except within 

 the dépression, the punctures gradually diminishing towards the 

 apex where they are very fine, the interstices not raised, with a few 

 fine punctures hère and there, underside black, the breast more or 

 less piceous. 



Hah. Ferguson Island (Meek). 



The black head and the rather longer thorax than usual are the 

 principal characters by which this species may be recognized. 



Rhyparida Blackburni n. sp. — Greenish or hrownish- 

 œneous, the labrum fulvous, the head and thorax impunctate, elytra 

 subcylindrical, strongly punctate-striate, the hiterstices impunctate. — 

 Length, 6 mill. 



Var. The femora and tibiœ fulvous. 



Of narrow, subcylindrical shape, the head minutely granulate, 

 metallic-greenish, the clypeus not separated, with a few fine punctu- 

 res, its anterior margin deeply emarginate, antennae extending to 

 the middle of the elytra, black, the lower two or three joints ful- 

 vous, the third and foUowing joints nearly equal; thorax scarcely 

 twice as broad as long, the sides rounded, narrowed in front, the 

 anterior angles scarcely produced, the surface sculptured like the 

 head, impunctate, minutely granulate; scutellum impunctate; 

 elytra wider at the base than ^he thorax, subcylindrical, with a
