10 D. Sharp. 



and basal depressions on the thorax. The thorax is coarsely 

 punctate. The elytra have regular rows of moderately large 

 and deep punctures, the interstices between them being quite 

 small. The palpi are yellow with the last joint infuscate at the 

 tip. The legs also are yellow, with the hind femora infuscate; 

 the front femora are slightly infuscate, and the tarsi have the 

 5 th joint spotted with black just before the claws. 



Thirteen specimens in backwater near the river, north of 

 Gebel Ahmed Agha; two on waterplants, G-ebel Ahmed Agha. 



29. Hydraena nilotica Schaum, Kuwert. This species was 

 not, I think, described by Schaum, but I have specimens of it sent 

 me by the late Herr von Kiesenwetter, and they are the same 

 species as those from the White Nile. The latter have been 

 preserved in spirit and are rather more contracted and convex, 

 but there is no other decided difference. 



White Nile, North of Kaka, March 1901. Several specimens.
