No. 457] CECANTHUS FASCIATUS. 9 
with the fluid, which seems to be partially soluble in water. 
When the gland becomes dried out, the evaporation of moisture 
causes the hairs, which are normally arranged in the flat rows 
before mentioned, to come together forming acute pencils. 
These pencils then take on the appearance of teeth, quite mis- 
leading to the casual observer. ‘A small drop of water carefully 
placed in the cavity, while under the microscope, soon dispels 
this illusion by causing the hairs to spread out in the same way 
that a hair brush shows its individual hairs after a dried, sticky 
substance has been soaked out of it. My illustration (Fig. 3) 
presents a view of the entire gland after being treated with a 
drop of water. 
From the foregoing statements regarding the sexual habits 
and the connection of this gland therewith, it may be of interest 
to note that the suggestion made by Blatchley (Orthoptera of 
Indiana, p. 452), that during the mating of this species the 
female removes the semen from the glands whose openings are 
intimated to be beneath the tegmina of the male, and that she 
then fertilizes her ova with the secretion there obtained is, as a 
matter of fact, wholly erroneous. There is also a doubt regard- 
ing the correctness of certain notes of Harrington on the habits 
of the snowy tree cricket, which has a bearing on this subject. 
Howard quotes Harrington as mentioning the following : * An 
interesting feature of its concerts is one of which I have not 
been able to find any mention in books accessible. While the 
male is energetically shuffling together his wings raised almost 
vertically, the female may be seen with her head applied to the 
base of the wings, evidently eager to get the full benefit of every 
note produced." (/nsect Book, p. 344.) My studies of the 
thoracic gland of the snowy cricket show this structure to be 
similar to that of the striped species, fasciatus ; consequently, 
is it not possible that Harrington witnessed the female in the 
act of drinking from the gland without realizing the entire mis- 
sion of her attitude? Blatchley gives an interesting account of 
the male wooing the female in the work before cited. He found 
them on the heads of the sunflower. 
Besides the alluring gland above referred to, this cecanthid 
has a singular eversible, sacculated structure situated at the dor-
