22,9) THE ENTOMOLOGIST S RECORD. 
is tabulated, and gives a surprising result. Of Orthoptera of all sub- 
orders, quantities drifted to the shore, mostly alive. All the Tettiyidae, 
well known for their swimming powers, escaped; of the Locustodea, 
none survived, but of (rryllodea and Acridiodea, half only were killed- 
Many dragonflies drifted along, and none survived. Of a number of 
Coccinellidae, Scarabaeidae, Chrysomelidae and Carabidae, a good many 
were dead, but of the survivors, only five per cent. were killed. Of the 
Diptera, Bombylidac and Muscidae were all drowned, but of the Asilidac, 
sixty per cent. escaped. All Hymenoptera reached the shore already 
dead. In Hemiptera, all the Pentatomidae were dead before approach- 
ing the shore, but of the Belostomatidac, themselves aquatic, ten per 
cent. were kill ed, mostly by accident, as the majority were more or less 
injured. Of a quantity of caddis. flies, apparently of the genus 
Glossosoma, which approached the shore mostly alive, ten per cent. 
were killed. The volume 1 is concluded by an article on “ The Argyn- 
nids of North America,” by A. J. Snyder. 
The Rev. F. D. Morice (Ent. Mo. May., July, 1900) advises ento- 
mologists when collecting Hymenoptera to * abandon cyanide and use 
only pure sulphuric ether without alcohol.’ He Says: «< Hymenoptera 
so killed, not only preserve absolutely their natural colours, even those 
delicate yellows which cyanide and ammonia almost always turn to 
brown or red, but die in natural positions—not cramped and distorted 
like the yictims of the other methods—and are, even so obliging 
usually as to open their mandibles and extend the whole cibarial 
apparatus so that it can be examined without any preparation of the 
specimen. These advantages and the perfect cleanness of specimens 
killed by ether seem to me much more than enough to repay the 
slight extra trouble and expense involved in using it. The one objec- 
tion to ether is its rapid evaporation, but this can be met by carrying 
a small phial in the waistcoat pocket, from which a few fresh drops 
can be supplied to the collecting-bottle from time to time as required, 
znd this should always be done as a coup-de-grace to finish off any 
possible survivors in the bottle when one returns from an expedition. 
Then if the bottle be kept well-corked and unopened for an hour or so: 
the result is almost sure to be satisfactory.” 
At the meeting of the Entom. Soc. of London, held on June 6th, 
1900, Sir G. F. Hampson exhibited specimens of a moth belonging to the 
subfamily Hydrocampinae of the Pyralidae — Oligostima aracalis, 
Hfampson, from Ceylon—where his correspondent, Mr. J. Pole, had 
met with a swarm on an island im a river which he estimated at 
20,000. When disturbed the buzz made by their wings was quite 
audible, and after three waves of the net 286 specimens were bottled 
from round its edges, the net still appearing quite full; as im the 
80 specimens sent the sexes were in almost even proportions, this was 
not a case of male assemblage. He also exhibited denuded wings, 
showing the neuration of Diacrisia russula, Tyria jacobacae, Callimorpha 
hera and C. dominula, the two former being typical Arctiadae and agree- 
ing with the definition of that family in the costal vein of the hindwing 
anastomosing with the subcostal to half the length of the cell, whilst 
in the two latter and also in the eight or ten other known species from 
the oriental region the costal vein does not anastomose with the sub- 
costal, but only connects with it at a point. He contended that the 
genus Callimorpha should therefore be removed from the Arctiadae and
