late June. Besides, many of the large caterpillars, and those 
that were parasitized, were wandering over the pavements or 
crawling on fences and so forth, and by their presence added 
more or less to the general annoyance. On that date many of 
the trees were completely stripped of foliage, while others 
bore large bare patches, entirely destroying their appearance. 
On September 23, 1904, the following note was made con- 
cerning this insect: “Nearly every catalpa tree in this vicinity 
was defoliated at some period during the present summer by 
these larvae; especially those on Lamar Avenue where the 
sidewalk was coated with pellets of frass for several months 
(August, September). Some of these trees put on as many 
as three sets of leaves during the season, while nearly all were 
stripped once and put out a second set. If this was repeated 
every season, the drain on the vitality of the trees would soon 
kill them.” 
According to notes the insect first made its appearance late 
in April. On May 7th, it was recorded that the larvae of the 
first generation were in instars II and III, and that these 
were pupating about May 21. The larvae of the second genera- 
tion were present in different instars on June 20th. On July 
Ist, eggs were found, and larvae were pupating in numbers on 
July 3d, so that the generations soon afterwards became con- 
siderably mixed, and the notes failed to record anything more 
definite than that the third generation of caterpillars was pres- 
ent in July. The moths were then common. Another lapse 
then occurs in the notes, but on September 23d, it was record- 
ed that a fourth generation of larvae was present many of 
which were nearly full grown. I am uncertain whether this 
was a fourth or fifth generation. It was noted that at that 
time the generation was much decreased in numbers, not as 
large, for instance, as the third generation. These notes indi- 
cate at least four generations of the species in northeastern 
Texas. The duration of the pupal instar in July was from 
about 10 to 12 days. 
The caterpillars were much attacked by tachina flies, but 
none of the flies were reared. On August 17th, 211 specimens
