XXXVII.— Notes on the Lepidoptera of St. Helena , ivfth 
Descriptions of new Species. By Mrs. T. Vernon Wol¬ 
laston. 
[Continued from p. 233.] 
Fam. III. Deltoid®. 
Genus 16. Hypenodes, Gudn. 
Hypenodes costcestrigalis , Steph. 
It is curious that the only example which we obtained of 
this little Deltoid in the island should happen to be such 
a remarkably dark variety. It was on the loftiest por¬ 
tion of the central ridge that we captured it, where it was 
adhering to the underside of a large and rotten block of cab¬ 
bage-tree wood which was lying on the damp grass ; although 
we frequently visited the same spot and made the most careful 
research, we were unable to obtain even a second specimen. 
At first sight it looks extremely like a member of the Phycidte; 
indeed I concluded that it actually was one until Mr. Barrett 
recognized it as undoubtedly Hypenodes costcestrigalis. 
Genus 17. Heeminia, Latr. 
Herminia rectalis , Eversm. 
This somewhat dingy-looking little moth (which occurs also 
in Casan and Orenburg) does not appear to be common at 
St. Helena. At any rate I obtained only two examples of it, 
and these at intermediate altitudes; but, as they were both of 
them found shortly before we left the island, it is not unlikely 
that our visit was not at the season when the moth is most 
plentiful. 
Fam. IV. Geometridae. 
Genus 18. Acidalia, Treits. 
Acidalia separata. 
Acidalia separata, Walk., in Mellias’s Saint Ilel. 186 (1875). 
This and the following Acidalia I have endeavoured to 
identify as well as I can from Mr. Walker’s descriptions. I 
cannot but feel, however, that the result is not altogether satis¬ 
factory, inasmuch as I have no knowledge of either of them in 
their earlier stages ; and I am inclined to suspect (at any rate 
until the contrary has been proved from an observation of the 
larvte) that they are probably but varieties of a single variable 
form. More particularly am I inclined to this view since 
Mr. Walker had evidently not seen a male of his A. separata.
