the fulvous margins of the elytra are more narrow in one of the 

 two spécimens which were kindly sent by Mr. Fruhstorfer. 



Sutrea apicipennis n. sp. — Black, the head, antennœ and the 

 thorax testaceous, impimctate, elytra hlack, impunctate a spot at the 

 middle and at the apex, yelloivish wite, legs testaceous, the posterior 

 femora hlack, — Length, 4-5 mlll. 



Hab. Trowbriand Island. 



It is not necessary to give a detailed description of thls species as 

 it agrées in ail structural characters with its congeners of which 

 S. Balyi Jac. is the one most closely allied, it differs from this species 

 in the testaceous, not black head and in the entirely impunctate 

 elytra which hâve a transversely shape whitish spot placed at the 

 middle and another at the extrême apex, in ail other species of the 

 genus, except S. Balyi the posterior elytral white spot (if présent) is 

 placed hefore the apex. 



Sutrea Mastersi Blackb. — I refer spécimens from N. Austra- 

 lia contained in my collection to this species, with the description 

 of which they nearly agrée, but in my spécimens there is no black 

 basai elytral spot, only an apical one and in some the elytra are 

 entirely testaceous like the whole insect; the species is possibly 

 subject to great variation or may be that my spécimens represent a 

 closely allied form. 



Sutrea flava n. sp. — Broadly ohlong-ovate, flavous or testaceous, 

 the inter médiate joints ofthe antennœ hlack, thorax and elytra entirely 

 impunctate. — Length, 8 mill. 



Head impunctate, the frontal tubercles feebly raised, triangular, 

 clypeus thickened and broad, labrum large, testaceous^ apex ot 

 mandibles black, antennae slender, extending to the middle of the 

 elytra, flavous, the five to the eighth joint black ; thorax more than 

 twice as broad as long, the sides rounded at the middle, the anterior 

 angles obliquely truncate, the basai margin produced at the middle, 

 the surface entirely impunctate, posterior angles in shape of a small 

 tooth, bearing a single seta; scutellum broadly triangular, elytra 

 ovately widened at the middle, pointed at the apex, impunctate like 

 the thorax; underside and legs flavous, posterior femora strongly 

 incrassate; anterior coxal cavities open. 



Hah, Philippine Islands. 



This and the following species are of much more rounded and 

 convex shape than is the case with the other members ofthe genus, 

 but I fail to see sufficient structural diflerences to separate them 

 generically, the filiform antennae, shape of the thorax and that of 

 the prosternum as well the open coxal cavities agrée entirely with 

 Sutrea,
