sections, and what is its name? Something should be done, and 

 done quickly." 



The specimens received consisted of injured stems, the in- 

 sects not being- present. Not being familiar with this form of 

 injury to the maple, the literature of economic entomology 

 was searched without finding descriptions of the damage or the 

 insect causing it. This was stated in replying to Mr. White's 

 letter, and he was requested to send more material, and if pos- 

 sible to send stems containing living larvae, so that we might 

 rear the adults. Under date of June 13th Mr. White wrote as 

 follows : 



"At your request I send you more stems and worms in a box 

 containing soil in which they have buried themselves. They 

 are now falling from the trees, and they soon disappear in the 

 ground, where I have reason to believe they remain in a chry- 

 salis state until another spring, when they come up to do their 

 destructive work, by laying their eggs in the stem of the young 

 and tender leaf. . . .If these pests increase as they have done for 

 two or three years past, the early foliage will be destroyed, and 

 I am afraid the trees likewise. It certainly is a new thing in 

 these parts. Perhaps nothing can be done until the habits of 

 the insect are determined." 



The material contained one living larvae in a stem, others in 

 the stem having been crushed. In the soil there were thirty 

 larvae, only five of which were alive. The soil was a trifle too 

 wet, and they had died in transit. The others soon died. 



No observations were made in 1900, but early in June, 1901, 

 I noticed that maple trees along the east side of Whitney Ave- 

 nue, New Haven, between Sachem and Humphrey Streets, 

 were attacked by this insect. I made several trips to these 

 trees, and gathered fallen leaves and stems, the latter contain- 

 ing a number of larvae. These were placed in a glass dish filled 

 with sand, which had previously been sterilized by heating. The 

 larvae at once went into the sand, which was only two inches 

 deep, and at the bottom made little cells as if to pupate. When 

 examined, a few days later, all had died without having really 

 transformed to pupae.
