Xenidea pusilla sp. nov. 



Black or piceons, above metallic blue, antennae (the ajiical joints excepted) 

 fulvous, thorax very strongly and suljremotely punctured, elytra convex, stronglv and 

 deeply punctate-striate, the interstices convex. 



Length 1 line. 



Head inipunctate, metallic lilue, the frontal elevations narrowly olilii|ue, joined 

 in front, bounded liehind by a deep oblicjue groove, eyes very large, antennae closelv 

 ajjproached at the base, fulvous, the apical joints more or less fuscons, first and second 

 joints thickened, third thinner but scarcely so long as the second one, apical joints 

 thickened, the last one fulvous again, extending nearly to the middle of the elvtra ; 

 thorax nearly twice as broad as long, convex, the sides straight, distinctly angulate 

 before the middle, obli(]uely shaped from there to the apex, posterior margin roundlv 

 produced at the middle, the surface strongly but not closely punctured, the punctures 

 irregularly distributed, the base with a very obsolete transverse groove ; scutellum 

 small, black ; elytra convex, subcylindrical, the sides with a feeble depression below 

 the base, the surface very strongly and deeply punctate-striate, each elytra with ten 

 rows of punctures (including the short subsutural one), the interstices rather stronglv 

 costate ; tibiae more or less obscure fulvous, sometimes the knees and tarsi of that 

 colour only ; posterior tibiae deeply sulcate, armed with a curved spine. 



Ifch. Humboldt Bay (New Guinea). 



Principally distinguished by its small size. 



Xenidea brevicornis sp. nov. 



Obscm-e fulvous, the intermediate joints of the antennae, black, apical joints 

 white, thorax finely and remotely punctured, elytra strongly punctate-striate, the 

 interstices at the sides costate. 



Length 1^ line. 



Of convex and parallel shape, entirely fulvous, the head impunctate, the space 

 between the eyes obliquely grooved, the groove bounded by narrow ridges, the clypeus 

 with some deep punctures, antennae not extending to the middle of the elytra, the 

 basal four joints fulvous, the following ones black, the apical two joints whitish, third 

 and fourth joints slender, equal, the following ones dilated ; thorax twice as broad as 

 long, the sides straight, slightly narrowed at the base, obliquelv angulate before the 

 middle, the posterior margin produced at the middle, the surface with a small impres- 

 sion at each side, finely and sparingly punctured ; elytra with a slight depression 

 below the base, the shoulders prominent, the smface deeply and regularly punctate- 

 striate, the punctures rather distantly placed, the interstices near the lateral margin 

 costate. 



Hab. Humboldt Bay (New Guinea). 



Smaller than X. purfnireipennis Baly, the general coloration dififerent and that 

 of the antennae ; the same differences and the much shoi'ter antennae separate the 

 species from any of its allies. 



Chaetocnema tenimberensis sp. nov. 



Below black, the antennae, anterior legs, and posterior tibiae fulvous, above 

 aeneous, head and thorax strongly and closely punctured, elytra stronglv and 

 regularly punctate-striate, the interstices longitudinally costate. 



Length f line.
