Tn September 1933 a large importation of senna (Cassia sp.) leaves, 
for medicinal purposes, from Sudan, Africa, was found by inspectors to 
be heavily infested with the caterpillars of a small moth and from these 
hundreds of moths were reared and captured. August Busck determined 
these as Tortilia n. sp. (family Heliodinidae) and submitted specs meae 
to the English cuthority Edward Meyrick. In letter of October 24 Mr. 
Meyrick verified the identification and wrote that he Nad never seen the 
species.’ The genus Tortilia was erected by Chretien (Bul. Soc. Ent. 
France, p. 201, 1908) for a single species, T. flavella Chretien, reared 
from flowers of Acacia sp. at Biskra, ‘Africa. The species found in 
this country is quite similar to the genotype in coloration and will be 
described by Mr. Busck as Tortilia viatrix (the traveler). It is the 
second known species of this genus.. - 
C. T. Greene has made identification of Anastrepha obliqua Macq. 
from the Canal Zone on the basis of material af larvae, pupae, and adults 
collected in Quararibea asterolepsis at Barro. Colorado Island, and by 
James Zetek. 
In August 1943 the Army Medical Corps decided to make a mosquito 
survey of the Civilian Conservation Corps cars throughout the country. 
Directions for collecting and packing insects were sent-out to the health 
officers in eacn camp and the specimens collected cach week were sent 
to the Army Medical Museum and then to this division for determination, 
Dr. Alan Stone, who personally examined all of the material sent in, re~ 
ports that the first lot arrived August 31, and that by the end-of Octoter 
over 16,000 mosquitoes had been received, when all but a few 6f the south 
ern camps had ceased collecting. Forty-three States, the exceptions being 
Delaware, Rhode Island, Idaho, Utah, and Nevada, sent in a tetal of 60 
positively determined species, distributed among the genera as followss 
Aedes 24, Culex 13, Psorophora and Anopheles / each, Theobaldia 4, Urano~ 
teenia 2, and Mansonia, Megarhinus, and Orthopodemyia, 1 each. Dyar in 
1928 recognized 114 species as occurring in the United States. Texas 
sent in the greatest number of species, 23, and Aedes vexans (Meig.) was 
the most widespread species, being collected in 29 States. Culex quin- 
guefasciatus Say occurred most abundantly, which is not surprising since 
the southern camps were best represented and most of the collecting was 
done inside tents or buildings. Anopheles quadrimaculatus Say was the 
second most abundant, and the presence of malaria in many of the camps, 
as reported in the collecting data, is easily understandable. Aedes 
acrypti (L.), the yellow-fever mosquito, occurred infrequently and in 
small numbers. No unusual distributions were found, but the survey gave 
a rather good picture of the mosquito population of the country at the 
end of the season,
