A NEW MOSQUITO FROM SAMOA. 37 
bands; in the mid pair very similar, but slightly more prominent ; in 
the hind the banding still more prominent, in all traces of it on the 
apices of the segments; femora and tibie with numerous black 
chet ; ungues small, equal and simple. 
Wings rather narrow, with dense brown scales, rather broad and 
straight with shorter and broader median vein-scales; first fork-cell 
longer but about the same width as the second fork-cell, their bases 
about level; stem of the first not quite half as long as the cell; 
stem of the second about half as long as the cell; posterior cross- 
vein much longer than the mid cross-vein close to it. Halteres with 
pale stem and large fuscous knob with pale scales, especially at the 
apex. 
Length, 4°8 mm. 
Habitat.—Apia, Samoa. 
Observations.—Described from a single perfect female sent 
me by Dr. K. Friederiks, Government Zoologist of Samoa; two 
specimens were taken in a privy. 
It forms a very marked species of Pseudoteniorhynchus, easily 
told by the brown thorax having no posterior pale spots and by 
the abdominal ornamentation. The type I have presented to 
the Liverpool School of Tropical Medicine. 
Dr. Friederiks tells me the other mosquitoes found in 
Samoa are Stegomyia fasciata, Fab.; Stegomyia pseudoscutellaris, 
Thorp ; Culex fatigans, Wied; and a species of Mansonia (i.e., 
Temorhynchus). 
SYNONYMY OF ICHNEUMON OBLITERATUS AND 
I. BARBIFRONS. 
By Cuaupe Mortey, F.E.S8. 
Some time ago Dr. T. A. Chapman was so good as to present 
me with a female of Ichneumon obliteratus, Wesmael (Ichn. 
Miscellanea, 1855, p. 18), which emerged on August 21st, 1910, 
from the pupa of Brenthis pales, found at Furka, in Switzerland, 
on 28th of the previous month. When first describing the 
species, Wesmael knew but a single female: ‘‘ M. le Dr. Kriech- 
baumer a pris cette femelle aux environs de UVoire, en Suisse.” 
Giraud (Ann. Soc. France, 1877, p. 898) says Fallou bred it— 
evidently still the female only—and adds in a footnote, ‘“‘ L’ J. 
obliteratus provient de chenilles d’Argynnis pales prises en juillet 
1866, autour de l’hospice du Simplon, dans le Valais,’ Switzer- 
land. Berthoumieu in 1894 simply epitomises this (somewhat 
incorrectly), and adds “‘ Holstein,” in Prussia, apparently on 
his own authority. ‘‘ Male inconnu.”’ 
Dr. Chapman has just sent me three more females with a 
single male, bred during August, 1912, at Col d’Iseran, in the
