apex, anterior angles oblique, the disc convex, imininctate, the base with an obsolete 

 transverse groove at the sides only, visible merely in a certain light, this portion dis- 

 tinctly punctured ; scutellum very short, transverse ; elytra scarcely jjerceptibly 

 depressed below the base, wider at that place than the thorax, regularly punctate- 

 striate, the punctures rather strong and distinct to the aj^ex, the interstices flat 

 except at the sides, where thev are slightly costate ; posterior femora strongly 

 iucrassate, their tibiae with a small si)ine, the first joint of the posterior tarsi sUghtly 

 longer than the following joint, the knees slightly stained with fulvous ; presternum 

 longer than broad, the anterior coxal cavities open. 



Hah. Halmaheira. 



This small species possesses all the structural characters oi Li/pnaeu Baly, from 

 New Guinea, but it resembles entirely a species of Aphthonu in shape and size ; 

 it is therefore quite distinct in that respect to Baly's genus, and represents probably 

 an allied form, especially on account of the very obsolete thoracic sulcus. In the 

 absence of more material I have placed it provisionally in the present genus. 



Docema apicicomis sp. nov. 



Oblong-ovate, piceous, antennae fulvous, the ajiical four or five joints black, head 

 and thorax fulvous, rugosely punctured, elytra piceous, closely and strongly punctured ; 

 legs more or less fulvous. 



Length 1 line. 



Head impunctate, fulvous, frontal elevations distinct, short, clypeus triangular, 

 antennae closely apj)roached, long and robust, the first two joints thickened, the 

 following three joints thinner, of equal length, the terminal foiu" joints thickened, 

 black, extending to the middle of the elytra ; thorax nearly twice as broad as long, 

 transversely convex, the sides straight, obliquely angulate anteriorly, the surface 

 rugosely punctured and wrinkled, with an ob.solete depression at the sides near the 

 base, fulvous ; elytra convex, subcylindrical, closely and strongly but rather evenly 

 and regularly punctured, piceous ; first joint of the posterior tarsi as long as the 

 following joints together ; anterior coxal cavities open. 



Ilab. Martapm-a (S.E. Borneo). 



Docema angnlicollis sp. nov. 



Obscure piceous or dark fulvous, antennae thin, nearly black, thorax strongly 

 punctured, the sides angulate before tlie middle, the base obsoletely sulcate, elytra 

 very strongly and closely p\mctured. 



Length | line. 



Head finely and sparingly punctured, eyes large, antennae feeble, extending only 

 a little beyond the base of the elytra, black, the second and third joints equal, the 

 terminal joints scarcely thicker; thorax twice as broad as long, transversely convex, 

 the sides straight, anteriorly obliqu(>ly angulate and followed by another angle near 

 t he middle ; the surface .strongly and closely punctured with a shallow but distinct 

 transverse groove near the base; elytra convex, piceous, the suture more or less 

 fulvous, the surface punctured like the thorax ; underside and legs obscure fulvous. 



JJah. Martapura (S.E. Borneo). 



The doubly angulate sides of the thorax, short antennae, and the di-stinct thoracic 

 sulcus distinguishes this species from the preceding one.
