regard these names (i.e. 7’. alaskdensis, T’. siberiensis and 
7’. arctica) as indicating, at most, slight local variations of a 
single species of holoarctic distribution.’’ In the same paper, 
however, he suggests provisional retention of the name T’. arctica 
until males from Alaska and Siberia are available for comparison. 
Recently, having occasion to examine a series of preparations 
of the male hypopygia of J’. annulata in the collection of the 
Liverpool School of Tropical Medicine, a specimen labelied 
‘‘ Cheshire 1912°’ was discovered which differed considerably 
from the others, but agreed with the characters given by Edwards 
for 7’. arctica. The male from which this preparation of the 
hypopygium had been made was then examined, and its colora- 
tion found to correspond closely with that described for 7’. arctica 
and 7’. alaskdensis. Subsequently a search through the 7’. annu- 
lata material in the collection revealed the presence of a second 
male of 7’. arctica ; this specimen was labelled ‘‘ bred from larva, 
Cheshire, 1912.’’ Unfortunately more exact data regarding 
these two specimens cannot be given, but it is highly probable 
that both were reared from larve, and that these were present 
in a mixed sample of mosquito larve collected in the Wirral 
Peninsula and intended for demonstration purposes. 
The existence of J’. arctica so far south as Cheshire is of 
considerable interest ; its unexpected appearance in this county 
emphasises the need—already indicated by recent discoverles— 
for more consistent and detailed work in connection with our 
indigenous mosquitoes.

THE HETEROPTERA OF INDO-CHINA. 
By W. L. Distant. 
(Continued from p. 6.) 
NEONIPHE, gen. nov. 
Closely allied to Niphe, Stal, but differing from that genus 
by the strongly-spined anterior femora, which are closely serrate 
beneath with a prominent spine before apex. 
Neontphe armata, sp. n. 
Ochraceous, thickly rather finely darkly punctate ; pronotum with 
a series of six impressed dark spots on anterior area; eyes pale dull 
castaneous; scutellum more darkly punctate on anterior area, the 
basal margin with pale ochraceous linear spots and the dise with 
indications of a central pale longitudinal fascia; corium paler on 
extreme lateral margin and with a narrow sublateral paler line;
