HELOTA JENTINKll. 225 



on the middle portion fine; the intercoxal part is bounded 

 laterally by raised margins which are divergent towards 

 the mesosternum ; this latter is sparsely punctured ; the 

 metasternum is strongly punctured in the anterior late- 

 ral angles and has an impressed line along the middle; 

 the elytral epipleurae have a few large punctures along 

 the inner margin near the base. — The ventral segments 

 are very finely punctured along the middle, more distinctly 

 along the sides and between the posterior coxae ; the apical 

 segment is subtruncate behind and provided in front of 

 the truncation with a rather shallow semiovate impression 

 which is very finely punctured but not pubescent; this 

 impression extends as far as the base of the segment. — 

 The dark coloured tip of the femora is strongly punctured, 

 the tibiae more finely; the upper margin of the anterior 

 tibiae is slightly and regularly curved, the inner margin 

 at the apical half more strongly curved and this curvation 

 ends at some distance from the apex, forming here a rather 

 blunt angle; the posterior tibiae are slightly longer than 

 the intermediate ones, and have, instead of the apical 

 tuft of long hairs, a stripe of a short white pubescence 

 along the inner margin of the fulvous apical portion ; all 

 the tibiae are somewhat narrowed at some distance from 

 their apex. 



Hah. Sumatra: Medau (Moissiuac). — The described 

 male-specimen is in the collection of the Leyden Museum. 



I have much pleasure in naming this interesting species 

 after my friend Dr. F. A. Jeotink, the well-known Director 

 of the Leyden Museum of Natural History. 



Helota Jentinkii is the 5<h species of the genus known 

 as yet from Sumatra. The four other species are: Vigorsii 

 Mc. L., Candezei Rits., hrevis Rits. and Bouchardi Rits.
