their third shorter joiut , the posterior first tarsal joiut is 

 also longer than in the species described by Mr. Baly. 

 The black underside and differently marked elytra will easily 

 separate the two species. 



Sastra fiihipennis , n. sp. 



Oblong-ovate , black. Antennae with the last 3 joints 

 whitish. Thorax finely punctured with some transverse 

 depressions. Elytra fulvous, pubescent, very finely and 

 closely punctured. — Length 3 lines. 



Head strongly punctured at each side in front of the 

 eyes , clypeus thickened , transverse. Palpi thin , filiform , 

 black. Antennae closely approached , nearly as long as 

 the body , black , the three or four terminal joints closely 

 covered with whitish hairs , the second joint short , the 

 third the longest and longer than the two preceeding ones 

 united. Thorax twice as broad as long, the sides constricted 

 at the base and apex , disk with a large triangular trans- 

 verse depression in front of the base and a smaller one at 

 each side near the anterior margin , another small but deep

 the West-Coast (Sumatra-Expeditionj. 



Although this species is of a posteriorly more dilated 

 shape than is usually the case in Mr. Baly's genus Sastra,
