impressed, so that two more or less evident ridges are formed between 

 this impression and the lateral foveae in some aspects. Elytra with the 

 humeral angles produced or subacute, and with a distinct, densely setose 

 tubercle on either side of the scutellum, the space between these tubercles 

 and the humeral angles strongly impressed. The mid-dorsal portion of 

 the elytra, for about two-thirds of their length, is flattened, but uneven, 

 bare and depressed areas occurring amidst the squamosely clothed sur- 

 face. The flattened area forms at its junction with the decurved sides 

 a pair of uneven lonigtudinal ridges, each terminating posteriorly as a 

 raised tubercle, owing to the apical portion of the elytra being of simple 

 convex form. The squamous covering of the pronotum and elytra is of 

 a greyisji golden color and is dense, but unevenly distributed, so as to 

 form niaculations on the elytra. The erect setae are very long and 

 spiniform, as also are those on the legs. The lobes of the tarsi are of 

 moderate size. The punctures of the ba.sal abdominal segment beneath 

 remain coarse and distinct on the middle part. Length, female, 5 mm.

 A single female of this interesting and beautiful s])eeies was 

 obtained 1)V ^fr. Swezey from the native palm, I'l IfcliairJlfi 

 luartll. an uneommon tree cm Oahu. Tn some respects it a]>- 

 ])ears to be a eonnecting link between the />lacl,-/iiiriil group and 

 the other members of the genus. 



Proterhinus euops n. sp. 



Head and thora.x of a sordid red, or reddish black, quite red if some- 

 what immature ; the elytra red and black, as a rule extensively dark 

 with the sides, base and apex more red. and the dark area containing 

 red spots. The antennae are somber red and the legs niucli paler than 

 these or ferruginous. 



Pronotum with almost even clothing of golden squamosity, wliich is 

 not very dense, but with a small distinct dense spot, often nearly white 

 at the hind angles. The elytra are maculate, the pale parts bearing 

 golden and whitish squamosity or appressed setae, the dark areas being- 

 bare, while the erect white setae are of moderate length, numerous, and 

 very conspicuous on the posterior parts. 



Head with large, outstanding, subconical eyes; strongly constricted 

 behind these, so that an evident tran.sverse ridge is formed. Antennae 

 rather long, with slender three-jointed club, the ninth joint being consid- 

 erably wider at the apex than the eighth. Rostrum of female shining, 

 the punctate grooves distinct. Pronotum and elytra formed exactly as 

 in some large examples of P. gracilis Sh.. the former constricted in front 

 and there impres.sed in the middle, the two impressions or foveae 

 behind this very distinct. Elytra long and narrow, nearly parallel-sided 

 until tliey become rounded off to the apex, tlic humeral angles acutely
