induced to record from time to time systematic observations upon 
the subject, that I have ventured to bring together some few 
facts and my conclusions touching the recent abnormal numbers 
of the species referred to in Britain.

-SYNONYMIC NOTES ON PHYTOPHAGOUS COLEOPTERA. 
By Martin Jacosy, F.E.S. 
Genus Derrectis, Clark. 
Two species have been described by Clark in the ‘ Annals of 
Natural History,’ 1865, and are contained in the collection of the 
British Museum. A comparison of the types has convinced me 
that Clark’s genus is identical with Antipha, Baly, described in 
the same Journal and in the same year. Clark’s name has, 
however, the priority, and should be retained. 
Pachytoma dives, Karsch., 1881 = 
Mesodonta submetallica, Jac., 1888. 
I think that this species was rightly placed by me in 
Mesodonta. 
Megalognatha Bohemanni, Baly = Cneorane foveicollis, Jac. 
Megalognatha elegans, Baly = Apophylia elegantula, Jac. 
Baly was probably right in placing these two species in 
Megalognatha. 
Stenoplatys robusta, Allard. 
A specimen kindly given to me by M. Duvivier, and named 
as above, differs entirely in structural characters from Steno- 
platys.

Some Prominent FEATURES OF THE PRESENT Season.—This season 
will apparently resemble that of 1888 in the abundance of Plusia gamma 
and Vanessa cardui. For the past three weeks or more P. gamma has 
been extremely abundant, both in the daytime and in the evenings, and the 
swarms round lilac-bushes at dusk have been really extraordinary. With 
regard to V. cardui (which I have not taken here since 1888), I have seen 
two or three specimens, and have heard of several other captures in the 
neighbourhood. Hybernated specimens of V. atalanta have also been 
unusually common. A still more welcome feature of this year is the 
appearance in Hinfield of another periodical insect, Colias edusa. Although 
I have been collecting Lepidoptera in this district for the past five years, I 
have never met with this butterfly till the present month, nor have I heard 
of a capture here of recent years. Last Saturday I saw a female specimen
