152 THE ENTOMOLOGIST. 
from the Continent of Europe we have no means of ascertaining, 
but I think that in the present day there are certain species 
which from time to time land on our shores and endeavour to 
colonise in suitable localities in our islands. The majority of 
these species seem, however, unable to effect a permanent 
establishment here.

CECIDOMYIA MURICATA, N. Sp. 
I Aver to record that I have succeeded, during the present 
month, in rearing a Cecid reputedly new to science. At all 
events Bergenstamm, in his Synopsis, published in 1876, says 
of it, “Imago unbekannt”; adding, as he groups it with other 
unknown and undescribed Cecids in the imago state, on the 
authority of Professor Loew, ‘‘ Die larven deformiren die Fruchte 
von Carex muricata.” I gathered the affected heads of the Carex 
in July of last year. The larva was then feeding on the embryo- 
nucule of the flowers, ensconced in the utricle, which is open at 
the end for the protrusion of the stigmas. Within this sac it 
pupated, spinning for itself a slight papery cocoon towards the 
end of the autumn. By removing a portion of the utricle the 
larve and pupe were visible by neans of a lens. The seed-heads 
were kept slightly moist by occasional sprinklings during the 
winter months. In February or March of the present year all 
had pupated. At the end of April the red pupe became redder 
through their slim covering, and I inferred that a further change 
was approaching. On the 16th of May my patience was rewarded : 
twelve Cecids appeared in my glass-topped box, mostly females ; 
but happily I observed among them a few males. Each succeeding 
morning, for a week and more, gave me a bevy of the tiny gall- 
gnat. I counted upwards of twenty on one morning. Dr. Meade, 
to whom I sent specimens, has kindly offered to append a scientific 
diagnosis of the species. This, I need hardly say, I much prize, 
as it comes from one that is an expert in the smaller and more 
abstruse forms of dipterous life, which he has made a special
