short, only slightly exserted ; wings slightly subhyaline, pubescent, the 
veins pale brown ; the postmarginal vein is very long, gradually shaving 
off at apex of wing; the marginal less than twice as long as the stigmal 
vein. 
The question of an author's right to change his published gen- 
eric or specific names was discussed. Dr. Forster, who intended 
to name the genus after Mr. Haliday, subsequently revised the 
name so as to read Halidaya instead of Halidea. Prof. Riley, 
Mr. Howard, and others held that, in this instance, the name was 
alterable, while Mr. Mann, Mr. Ashmead, and Dr. Fox held that 
a name once published should hold, unless there was a gross typo- 
graphical error.

FURTHER NOTE ON DISSOSTEIRA (CEDIPODA) CAROLINA. 
By TYLER TOWNSEND. 
In the September number of the Can. Entom. for 1884 there appeared 
some notes by myself on the peculiar aerial performances of this locust, 
common throughout the U. S., and which Mr. Bruner tells me he has taken 
even in southern Mexico. The observations there given, as well as the 
present notes, were made in Michigan, and the latter being somewhat 
supplementary during two subsequent years are offered as follows : 
During August and September of 1885, while observing the actions of 
this locust, I noticed that when one individual was attracted by another's 
oscillations, it alighted on the ground beside it as soon as the latter had 
ceased its aerial performance, when they ran by each other several times 
in succession, but did not clasp, as I had observed them to do before. No 
further observations were made on the subject until the following year, so 
that up to this time I had never examined the sex of these individuals, but 
nevertheless believed them to be in all cases males. 
In 1886 the first performance of the season was noticed on July 27, the 
first specimen having been seen on July i. On August 7 a specimen cap- 
tured in the oscillating act proved on examination to be a male. On Au- 
gust 8 I had the opportunity of closely watching individuals as they went 
through their peculiar actions, when meeting on the ground, these actions 
being somewhat different from what I had previously noted. When two 
met on the ground, one having been attracted by the other's aerial exhibi- 
tions, they passed closely by each other once, twice, and perhaps sev- 
eral times, alternately jerking up and lowering the hind femora during 
the whole time, and more excitedly when nearest to each other. This 
continued for a few seconds, when one of the actors in the scene quickly 
flew up and away. I noticed these actions at this time in numerous cases 
without seeing any two thus engaged unite. On the other hand, I did not
