46 BULLETIN BROOKLYN ENTOM. SUvu. VOL. VI. August 1883] 
* 
Last December shortly before the Christmas holidays a hat store in 
Pittsburgh was found to be alive with specimens of Alta argillacea 
The clerks say nearly a peck of them were swept out into the snow. 
The windows were alive with them and in every cranny and behind every 
hat box they were found, ‘The weather was very cold at the time, 
though the building was warm. I have a number of specimens of the 
swarm, a young entomological friend having captured in his cyanide jar 
nearly a pint of them. Mr. A. Koebele, of Washington, D. C., informs 
me that this is the most northerly instance known of the swarming of this 
species so late in the season. Where did they come from?

The singular difference between the mouth organs of the two sexes ~ 
in Lupsahs minuta has been noted with curiosity by naturalists My 
esteemed friend Dr. John Hamilton of Allegheny, Pa. tells me the male 
employs the singular forceps with which he is armed in extricating the 
proboscis of the female from the bark of the tree in which she sometimes 
gets stuck boring a hole in which to deposit her eggs. Here is certainly 
a most remarkable provision on the part of nature to meet contingencies. 
The family starts out with an auger and a pair of plumbers tongs with 
which to do the mechanical work necessary to the perpetuation of the 
speeies.

Part I. The Legs. 
(Continued from p. 34.) 
Flerminia (Chylolita) morbidalis, is almost the reverse of the foregoing 
so far as the anterior legs of the ¢' are concerned : the median and post- 
erior legs are long and slender, showing no remarkable peculiarity and the 
anterior legs of the O are except for the proportion, in which they agree 
with the <j‘, normal. The j' has the anterior coxa, femur and tibia 
of nearly equal length and very slender, the coxa is very decidedly exca— 
vate above leaving only a mere shell, and there is a heavy brush of hair, 
attached at base. The femur is equally slender, and also excavated 
above and it has a very heavy brush of hair attached at “p. The tibia is 
slender, has a very decided excavation at base on the inner side covered 
by the small lappet, and has the entire outer side grooved for the recep- 
tion of the heavy brush of hair attached at base. The unusually slender
