6 D. Sharp. 



que anterioribus piceis; elytris ad latera minus subtiliter punc- 

 tato-striatis. Long, (capite deflexo) & 1 / 8 mm. 



This is in appearance very like several species that are 

 found in widely separated localities, and that are frequently 

 named V. aeneus Br. in collections; but from all of them it is 

 distinguished by the dark colour of the palpi. These, though 

 flavescent are, on all the joints extensively infuscate in the 

 manner that in this genus usually occurs only on the tip of the 

 last joint. There was only one female found of this species. 

 The spine on the last ventral plate is very small, and the arma- 

 ture of the hind margin is not very distinct. The diffuse sculp- 

 ture of the upper surface is numerous, and the striae at the 

 sides are very distinct. 



Gebel Ahmed Agha. One specimen; in a backwater near 

 the river; 20 th March 1901. Named in honour of Assistant 

 Professor L. A. Jagerskiold of Upsala, who was instrumental 

 in this expedition and forwarded the water-beetles to me. 



There is an old specimen of this species, in my collection 

 labelled "Casamanca, Africa, Bocande". I obtained it many years 

 ago with Reiche's collection of Palpicorn Coleoptera.
