hipustulata seems to prefer Lemna-coYeveA ditches with a considerable 

 depth of clear water, but I have it also from ponds and wet moss. 

 A. globulus I have met with less frequently than ovata. 



Although the name ovata, Reiche, is employed by Everts and 

 Seidlitz in the sense in which it is used here, it seems doubtful 

 whether this can be the oldest name for the insect in question. One 

 would like to use the name ochracea, Steph., for it, but the Stephen- 

 sian description is not conclusive and Mr. Gahan, to whom I sent a 

 specimen, tells me that it is not like any of those standing under the 

 name ochracea in Stephen's collection ; the latter, in his opinion, being 

 likely to prove hipustulata, Marsh.

NOTE ON THE ? OF ACRMA CHILO, Godm. 

 BT S. A. NEAVE, M.A., B.SC, F.E.S. 



When recently arranging some of the African Aeneas in the 

 Hope Department, Oxford University Museum, I was much struck 

 with the appearance of the ? ? of Acrcea chilo, Godm., in a series 

 collected by Mr. H. A. Byatt in Somaliland. These are more 

 diaphanous and much less heavily scaled, especially as regards the 

 hind-wing, than the type of the ? from Abyssinia figured by 

 Dr. Godman.* The Somaliland specimens, however, exhibit a good 

 deal of variation, and one individual, although of a pinker shade, is 

 nearly as heavily scaled as the type. 



On further examining the series of this species in the Hope 

 Department, from British E. Africa, chiefly from the neighbourhood 

 of Mombasa, I could at first find no ? ? . Subsequently, however, I 

 found that what are undoubtedly the ? ? of this species have 

 already been described by Mr. Grose-Smithf under the name crystal. 

 Una. 



All individuals under this name, both in the Hope Department 

 and in the National Collection, are ? ? , and a little comparison serves 

 to show that they only present an extreme phase of the less diapha- 

 nous Somaliland ? ? . I can find no constant difference between the 

 (J (J from the two districts, and it would therefore appear that the
