stout. First costal division slightly longer than second, the latter nearly twice as 
long as third; last section of fourth vein about five times as long as preceding section. 
Length, 3.5-4 mm. 
Type locality, Long Beach, Cal., July 7, 1916, reared in the New York State Mu¬ 
seum from a bract-covered gall on Distichlis apicata collected by Prof. E. Bethel, 
This species is allied to declinata Becker but that species differs essentially in color 
and structure of head.

Codling Moth Activities at Time of Total Eclipse. The writer observed the 
activities of the codling moth during the period of the sun’s eclipse, June 8, 1918, at 
Hood River, Oregon. The notes were taken in the Experiment Station orchard. 
This particular insect is quiet during the daytime, engaging itself in mating and egg 
laying at twilight and continuing on into the night if temperatures are sufficiently 
high. The effect of this unnatural darkness upon the insects was therefore watched 
with interest. 
At Hood River totality was reached at 4 o’clock. At 3.47 light became sufficiently 
subdued to cause the insects to take wing. They immediately began to seek out 
favorable locations upon which to deposit eggs and an insect was observed depositing 
an egg at 3.50. This was followed by the deposition of two others shortly thereafter, 
following which it became too dark to observe further activities and this particular 
moth was lost sight of. Moths were noted on the wing until 4.15 after which it ap¬ 
parently became so light that the inclination for further egg laying left them. Egg 
laying was noted as taking place normally at 8 o’clock in the evening of this date. 
The temperature during the half hour between 3.45 and 4.15 dropped exactly 10° 
F., or from 86° F. to 76° F. 
The rapidly diminishing light and temperature had a very decided influence upon 
all insect fife. The day was particularly favorable for general insect activities, being 
both quiet and warm, with many flowers in bloom. Many species of bees and flower 
flies were on the wing and the hum of the insects in their flights was distinctly audible. 
As darkness approached the flights of the insects almost instantly ceased and with it 
the hum of their busy wings. The death-like quiet which followed for a few moments 
due to this added further to the strangeness of the scene. Several species of bees, 
Syrphids and Tipulids were noted at rest on apple foliage as the sun’s light began to 
establish itself.

Culicidae of Colorado. Through the kindness of Prof. C. P. Gillette, we have 
been permitted to examine the Culicidae in the collection of the State Agricultural 
College. The specimens do not bear the names of collectors, but most, at least, ap¬ 
pear to have been obtained by Mr. G. P. Weldon. There is one species new to the 
state; Aedes cinereus Mg., three from Estes Park, July 11, 1912. One of these had 
already been determined by Mr. Knab. The Anopheles quadrimaculatus from Hotch¬ 
kiss appear to have the pale bands on thorax better defined than in eastern specimens, 
and more material may indicate a subspecies. The following are new records from 
localities from which we already had some material: 
Delta. Aedes curriei, 20 9 , A. vexans 1 9, all July 18, 1911. 
Estes Park. Aedes samsoni, 9 9, July 11 and 16. Also 18 9 apparently A. pul - 
latus, but none perfect. 
Grand Junction. Aedes nigromaculis, 22 9, July 12 and 27; A. curriei, 18 9, 
July 12, 13, Aug. 10; A. vexans, 14 9, May 24, July 14, Aug. 30. It appears that
