r/Ii ami 15 th of June, in the present year, the 2)retty 
little Phthorohlastis ocheenheimeriana occurred at ilerton in the 
same locality as before. Hying during the afternoon at the ends of the 
higliest brandies of Abies cephalouica on trees of about thirty-five 
years’ growth. The specimens were for the most jiart worn. I had 
louiul a single male in gooil condition nearly a fortnight earlier • 
but, unfortunately, tlio moment wlien the greatest number of rrood' 
siiecimcns might have been taken was missed. Tliis species 
although rather later than usual in its appearance, was certainly 
more abundant than when I had observed it in previous years • 
from which it may reasonably be conjectured, that tlie larvaj do not 
teed in the cones of the Firs; the trees on which tbey are found 
having produced scarcely a single cone in the season of 1880 but 
as there is now an abundant crop this question can easily be 
determined. Mr. C. G. Larrett (Ent. Mon. Mag. vol. xv i> 14 G) 
compares ochsenheimeriana with strobilella, to wliich lie considers it 
to bo nearly allied ; but these two species are placed widely apart 
in continental collections— as in Staudinger and Wocke’s cataWue 
.//•o 5 i/d/«belongingtothegenus Grapholiiha, H.S ., ochsenheimeriana 
being placed by Heinemann’s system of classification in the -eniis 
rhthoroblastis, Led., of which the male has no vein eiidiim in 
the costa of the hind Avings. ° 
]\fr. r.arretts remarks (/. c.) as to the introduction of this and 
oiher continental species into England, make it interestiim to 
observe, tliat Abies cephalonica was introduced at I^rerton*^ ex 
clusively by means of seed; and I am not aware that any foreign
