vein and the second long vein just before it branches ; there is also 
a patch of pale scale in the middle of each branch of the second 
fork-cell; the sixth long vein is black scaled for about half its 
length, and again at the base, the middle being pale; all the 
remaining veins with longish black scales; first sub-marginal cell 
longer and narrower than the second posterior cell; fringe black, 
except at the end of the second branch of the fifth long vein, 
where it is paler. 
Length. —5 mm. ; of wings, 6 mm. 
Habitat. —Lake Simcoe, Ontario (E. M. Walker); also New 
Orleans, New York (Fitch). 
Professor Howard gives the following localities in the States : 
Massachusetts, Maryland, Columbia, New York, Illinois, Texas, 
New Mexico, Connecticut, New Jersey, Virginia, Kansas, and 
Baltimore. Jamaica is also given as a locality, but none have 
been received in collections at the Museum from there. A 
related species but quite distinct has just been received from the 
West Indies. 
Time of capture. —September in Ontario; February at 
Castleton; September, October, and June in Massachusetts; 
March and November in Maryland ; June and October in 
Columbia ; April and August in New York ; October in Illinois ; 
May, June, and October in Virginia. 
Observations.— This American species very much resembles at 
first sight A. Sinensis and A. barbirostris; it differs from both, 
however, in having no pale hairs on the apical fringe of the wings 
and the greater length of the wings as well as in the thoracic 
ornamentation. Wiedemann regarded this species as synonymous 
with his A. crucians , but it is quite distinct. The costa in A. crucians 
is uniformly dark, whilst in A. punctipennis there are yellowish- 
white spots as described above, and there are three black spots 
on the sixth vein in A. crucians instead of two as in this species. 
On the other hand, Fitch’s Gulex hyemalis is undoubtedly this 
insect. The type of C. hyemalis is in the British Museum 
collection. This insect has been taken when the temperature 
was 6° F. 
This Anophe'es is known as the “ winter mosquito,” and is 
met with in the last days of autumn, and again for a short time 
in the first days of spring, and specimens are occasionally found 
throughout the winter months. A large winged variety seems 
to exist (Fig. 24, PI. IV.).
