fourth August 20-27, and the fifth September 1to-15. The 
broods gradually decreased in numbers of individuals until there 
were very few to appear in the last brood. The food supply 
began to get scarce after the second brood, and decaying po- 
tatoes were added, for which the larve showed great fondness. 
The second jar, containing the decaying vegetable culture, 
was left standing uncovered in the insectary all summer. The 
mosquitoes did not return to it and no signs of Psychodids 
appeared in it. The water nearly all evaporated, so that by the 
first of December only a small quantity of water remained in 
the bottom to keep the grass and weeds moist. 
While rearranging the insect breeding cages on December 9, 
I was surprised on lifting up the jar containing the culture 
to see a half dozen or so adult Psychodids fly out of it. The 
jar was immediately covered and removed to my laboratory. 
On the following day a few more adults emerged, but by the 
most careful examination no larve or pupz could be found. 
A number of the adults were collected and mounted, while 
the rest were left in the jar for breeding. The second brood 
of larve and pupz appeared during Christmas vacation when I 
was away and on my return the 5th of January, a great many 
adults were present in the jar. Some of the adults were again 
collected and others left for breeding. On the 6th and 7th of 
January the first signs of larvee were noted. They had just 
hatched and were extremely small, and unlike the larve of 
the other species I have observed, were very sluggish. The 
first pupze from this brood of larvee were found on the 15th of 
January and adults began to emerge on the 16th. Only three 
broods of this Psychodid were reared; the adults appearing — 
Dec. — to Dec. 9; Dec. — to Jan. 6; Jan. 16 to 25. Stragglers 
from the last brood continued to appear until the middie of 
February and a few specimens again appeared the last of 
March. 
Returning to the first species, which was bred between June 
15 and Sept. 15, I find, on comparing it with Ps. floridica* —
