488 Longicornia Malay ana. 



In one of my specimens the pubescence is somewhat 

 ashy, and in parts of a beautiful glaucous blue, indis- 

 tinctly representing three oblique bands ; a smaller one 

 from Dorey is much worn — nearly glabrous in fact — but 

 it apparently belongs to this species. 



Polyxo superans. 



P. fusca, grisescenti-pubescens ; scutello transverse, 

 fere semicirculari ; elytris subtilissime sparsim 

 punctatis, apicibus truncatis; tibiis anticis et inter- 

 mediis cuprescentibus ; antennis pallide brunneis. 



Hah. — Waigiou. 



Dark brown, with a short grayish pubescence ; head 

 with an oblong longitudinal fossa between the eyes, the 

 face and cheeks with scattered punctures ; prothorax 

 irregularly punctured, the central glossy patch rather nar- 

 row ; scutellum transverse, nearly semicircular ; elytra much 

 broader at the base than the prothorax, with a few minute 

 scattered punctures, the centro-basal patch surrounded 

 with small grayish spots formed by a denser pubescence, 

 two or three more or less imperfect bands made up of 

 the same kind of spots behind the middle, apices sub- 

 truncate ; body beneath and femora glossy black, the 

 sides of the former with patches of grayish pubescence 

 which are themselves varied with glabrous spots; an- 

 terior and intei'mediate tibiae with a coppery tinge; 

 antennge pale brown. 



Length 13 lines. 



Differs from the preceding and following, inter alia, in 

 the shape of the scutellum, and in the finer punctures and 

 the truncate apices of the elytra. 



Polyxo patricia. 

 Polyxo patricius, J. Thomson, Syst. Ceramb. p. 545. 



P. fusca, grisescenti-pubescens ; scutello subtrans- 

 verso, lateribus parallelis, apice subacuto ; elytris 

 subtiliter et sparsim punctatis, apicibus truncato- 

 emarginatis. 



Hab. — Amboyna, Aru. 



This species is particularly distinguished from the two 

 former by the scutellum, which is slightly transverse.
