very strikingly on the light ground. (3) Of Nisoniades tages ab. poliodes, 
which is difficult to recognise as this species, except that an aunteapical 
subcostal white point is seen clearly on the forewings, it is scarcely 
possible to distinguish the small marginal spots, the black marginal 
border on the disca! markings, the whole surface of the forewings is of 
a pale brown, and of the hindwings almost entirely whitish with white 
fringe, the whole underside is of a pale yellow with the normal mark- 
ings scarcely apparent. (4) Of Brenthis euphrosyne ab. chloroyrapha, 
in which the internal space between mervures 1 and 2, in the median 
region on the forewing’s upper surface, contains a well developed 
whitish-yellow cloud, and is homologous with ab. chlorographa of B. 
selene (Rev. Mens., 1912, with fig.); and (5) Of Coenonympha arcania 
ab. evocellata, in which the forewings have no subapical spot below. 
In the Doings of Societies Section of the Hnt. News, we read that. 
Dr. Skinner exhibited at the Entomological Society of Philadelphia a 
wonderful gynandromorph of Papilio turnus, baving the right wings of 
a yellow male and the left of a black female form, captured in July, 
1919, at Merion, Pa. In the same magazine E. G. Smyth gives an 
account of the insects which are pests of cotton in Porto Rico; so far 
the presence of the dreaded pink boll worm, Pectinophora gossypiella, 
has not yet been found, yet the list of enemies is formidable enough. 
Werner Marchand writes on ‘“ Thermotropism in Insects,” giving the 
results of his observations and experiments. Among the characteristic 
cases of this phenomenon are included those of the cockroach, and 
particularly mosquitoes, which are attracted by the heat of the human 
skin. 
In the Wnt. Mo. Mag. Mr. J. H. Keys describes a new sub-genus of 
the Staphylinidae (Col.), named Playiarthrina, and in it places a species 
new to science, which he describes and names P. furdhamiana from 
specimens sent to him by Dr. Fordham, who found them in flood- 
refuse, at Selby, Yorkshire, in January, 1919. It resembles the genus 
Metaxya. 
The Canadian Intomologist, in its “ Popular and Practical Ento- 
mology,” contains an interesting account of a day’s collecting Longi- 
corn beetles in the wocds near Peterborough, Ontario, a full account of 
the ‘‘ Imported Currant Worm,” Pteronis ribesti, and some fragments 
of the Life-histories of a few Manitoba Insects. There is an obituary 
of the late Dr. Gordon Hewett, who, to our surprise (knowing of him 
by repute alone), was only 35 years of age at his decease. It was as 
recently as 1909 that he left Mngland for the Dominion, and yet in 
that short period of eleven years he had initiated and carried out such 
excellent economic work, that the Council of the Entomological Society 
of Ontario said of him that they ‘desire to place on record their high 
appreciation of his eminence in this branch of Science, and of the 
notable work that he carried on by establishing field laboratories, which 
he directed at the central office in Ottawa.’ He had already passed 
the chair of the Society. Dr. McDunnough writes some notes on the 
larvee and pup of several Pterophorids and gives a plate of figures 
(enlarged) of the pup of four species. There are several papers on 
Myriapoda, which order seems to be attracting some amount of atten- 
tion lately from the readers of the magazine. 
Under a “Plea for Definitiveness,” a correspondent of the Ant. 
News points out that many contributions, dealing with a species,
