NEW GENERA AND SPECIES OF PHYTOPHAGOUS COLEOPTERA. 6 



juperinse of Chapuis' arrangement, but is altogether of entirely 

 iiffereut aspect and shape, being broad, robust, and elongate, 

 omewhat of the shape of some species of Oides. The ex- 

 remelj' long antennae, very slender and elongate legs, shape of 

 he thorax, and the peculiar subaeneous coloration will at once 

 .istiuguish the genus from any of the tribe Galerucinse. 



Pal(Sosastra gracilicornis, sp. n. 



Obscure feueous, the antennae, tibia?, and tarsi and the abdomen 

 lack, lower portion of the femora fulvous ; thorax closely punctured ; 

 lytra fuscous-^neous, extremely closely and finely punctured, 

 jength, 16 mill. 



Head impunctate, the vertex rather convex, frontal elevations 

 longate, trigonate, clypeus broad, rugosely punctured, eyes large, 

 bloug, antennae black, extremely long and slender ; the third joint 

 iaore strongly curved at the apex than the following ones. Thorax 

 idth the angles produced, subtuberculiform, the space in front of the 

 losterior angles thickened, the surface distinctly and closely punc- 

 jLired, the sides with a round fovea, the base with a broader, more 

 [hallow depression. Scutellum punctured. Elytra much wider at the 

 ase than the thorax, the shoulders rounded, the entire surface very 

 losely puuctured, the punctures scarcely finer than those of the 

 borax, except towards the apex. The breast obscure metallic, like 

 be elytra, abdomen blackish. Legs long, thin and slender, femora 

 alvous, their apex and the tibiae and tarsi black. 



Hah. Owgarra, New Guinea (A. S. Meek). 



Papuania, gen. nov. 



Oblong-ovate, strongly convex and widened posteriorly, antennae 

 mg and filiform, the second joint short, the third slightly shorter 

 ban the fourth, the following joints equal. Thorax subquadrate, 

 trongly constricted at the base, transversely sulcate. Scutellum 

 lightly louger than broad, convex. Elytra much wider at the base 

 ban the thorax, deeply transversely depressed anteriorly, the posterior 

 ortiou strongly widened and convex, their epipleurfB broad at the 

 ase, entirely disappearing below the middle. Legs long and slender, 

 he tibiffi unarmed, the metatarsus as long as the following three 

 Dints together, claws bifid; prosternum mvisible between the coxae, 

 he anterior cotyloid cavities closed. 



The genus proposed here for the reception of this insect has 

 ery much the appearance of the Indian genus Agetocera in 

 egard to the thorax and the elytra, but the very long and 

 lender antennae, unarmed tibiae, and the structure of the 

 lytral epipleurae, as well as that of the anterior cotyloid 

 avities, differ entirely from the last-named genus, and do not 

 it in any group of Chapuis' arrangement of genera. 



Papuania impressipennis, sp. n. 

 Fulvous, the antennas (the basal joints excepted), the breast and 

 3gs black ; thorax impunctate ; elytra metallic greenish-blue, deeply
