MeJanomyia nana, IVTg. — common at West Rimton and Chalfoi\l, Grlos. At 

 West Runton I found tliem in little groups settled on leaves. 



MiUogramma punctata, Mg. — several at West Runton on a sandy bank where 

 many Aculeates were nesting ; also some on ragwort blooms. 



Metopla leucocephala, Rossi. — West Runton, Sutton Coldfield, and Cranliam, 

 Glos. 



Macronychia agrestis. Fall. — one specimen from West Runton. 



Dexiosoma caninum, F. — abundant at West Runton amongst the bracken. It 

 seems to be usually found settled on tlie bracken, where it grows thickly, and is 

 often abundant. 



Dliiera ffi-isescens, Fall. — West Runton. 



Prosena siberito, F. — common at West Runton, where I got a nice series. It 

 was specially common on the ragwort, but also occurred on burdock and other flowers. 



Mt/iocera carinifrons,^a.\\. — Wyre Forest in September. 



I also took a number of specimens of the genus Harcopluiga, but those I will 

 not venture to name at pi-esent. 



In the above list I have only given those species which I obtained 

 during 1900. In my collection, however, are a number of other in- 

 teresting species taken in former years, which will probably form the 

 occasion of another note. It will be seen that in this one year alone 

 several species new to us occurred, and doubtless many others remain 

 to be discovered. 



I would appeal, in conclusion, to breeders of Lepidoptera or 

 other insects to save for me any Dipterous parasites they may breed, 

 and to let me have them with, if possible, the name of the species 

 from which they were bred.

ON A NEW GENUS OP GEOMETRIDM FROM THE HAWAIIAN 



ISLANDS. 



BY E. C. L. PERKINS, B.A. 



The Hawaiian Selidosemidce are a most important part of the 

 Lepidopterous fauna, thirty-four species having been already de- 

 scribed. These are distributed very unevenly in three genera, all 

 peculiar to the islands, since two of these genera contain together 

 but three of. the species. The large genus Scotorhythra, containing 

 the rest of the species, will, however, at some time be subdivided, 

 since the males furnish excellent structural characters for such division. 

 The difficulty of finding good generic characters in both sexes is 

 manifest very generally in most of the Orders of insects inhabiting 

 the islands, and in cases where the characters are very pronounced in
