THE ENTOMOLOGIST. 



described from three males taken by Mann in Sicily, now in the 

 Vienna Museum. 



Polycentropusflavomacidatus, Pict. — Two males. 



RhyacopJiila rougemonti, McL., var. sicula, nov. var. — In this 

 form the male appendages are very similar to those of the type 

 as figured by McLachlan, although in the single male before me 

 the inner parts cannot be seen clearly. The principal difference 



is visible in the lateral view; the second joint of the inferior 

 appendage has its hind margin with a much shallower incision in 

 the Sicilian form. 



The discovery of this insect in Sicily throws an important 

 light on the origin of the type. It was given to McLachlan by 

 Professor de Kougemont, and was stated by the latter to have 

 been taken by him at St. Aubin, Neuchtitel. McLachlan was, 

 however, never quite satisfied that this locality was the right one, 

 de Eougemont having also collected in Italy, and this doubt was 

 increased by the discovery of a male very close to the type in 

 Corsica. The species has never to my knowledge been found 

 again north of the Alps, and I am of the belief that de Piougemont 

 made some mistake, and that it will prove to be a purely southern 

 form. 



All the examples noticed here were taken at Taormina in the 

 beginning of April.
