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 2Oth. 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 in star 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 I7th, 211 specimens
