Hah. Philippine Islands. 



In ils System of coloration, the présent species agrées almost 

 entirely with C. festiva Baly and to a less extend with some others 

 of the genus, but it seems to difïer from ail in the smooth and 

 sparingly punctured elytra and that of the thorax which is the same 

 in the three spécimens contained in my collection, and which is 

 the same in both sexes, in nearly ail other species the interstices of 

 the elytra are more or less costate. 



Rhyparida Ribbei n. sp. — Below piceous, ahove hlack, the 

 anterior part of the head and the basai joints of the antennœ fulvoiis, 

 thorax closely and finely punctured^ elytra strongly, closely and 

 semiregularly punctured, the interstices slightly rugose. — Lenght, 

 7 mill. 



Head finely and not very closely punctured, the interstices minu- 

 tely granulate, black at the vertex, the lower portion fulvous, the 

 middle with a longitudinal groove, clypeus subquadrate, separated 

 from the face by a transverse groove, strongly punctured, its anterior 

 margin semicircularly emarginate, labrum fulvous, palpi filiform, 

 flavous, antennae extending to the middle of the elytra, black, the 

 lower four or five joints pale fulvous, eyes very large, deeply 

 notched ; thorax more than twice as broad as long, the sides parallel 

 near the base, from there to the apex obliquely narrowed, the 

 angles dentiform,the surface closely and finely punctured, the punc- 

 tures of différent sizes, scutellum broad, impunctate, black; elytra 

 without basai dépression, strongly and closely punctured, the punc- 

 tures semiregularly arranged in rows, the interstices somewhat 

 rugose, with some traces of longitudinal costae near the suture ; 

 underside piceous, the base of the femora more or less fulvous. 



Hab. Salomon Archipelago, Shortlands Isle (Ribbe), 



This species may be known from any of its nearly similarly colou- 

 red congeners by the fulvous colour of the anterior portion of the 

 head and the very close and strong punctuation of the elytra which 

 is less regularly arranged than in most other species of the genus. 



Rhyparida semipurpurea n. sp. — Below greenish piceous, 

 above obscure purplish or greenish œneous, the basai joints of the 

 antennœ fulvous, thorax finely and subremotely punctured, elytra 

 finely punctate-striate, the base more strongly punctured. — Length, 

 9-10 mill. 



Head greenish or purplish, strongly and rather closely punctu- 

 red, the epistome separated from the face by an obsolète transverse
