Mcnyanthcs, the principal visitors were Eristalis occidentalis 

 Will., Neoascia giobosa L., and Melanostoma mcllinum (L.). 

 At Ncphrophyllidium the only insect taken was Melanostoma 

 mcllinum (L.), while at S lever sia a number of Muscidee were 

 captured, as well as one species of Syrphidae {Melanostoma 

 trichophus Thomson). In the spathes of Lyslclilton, a beetle 

 (Donacia fcmoralis Kby.) was found at work devouring pollen, 

 and here also occurred the fly, Syrphus ribesii L.

 manus Loew being especially abundant. Of the Muscidae, the 

 most interesting were Orthocluvta pilosa (Zett.), a European
