LIST OF INSECTS. 255 



properly punished for my indolence, for, though I searched carefully day after 

 day, I did not find one. I cannot account for this. 



N.B. — Like my friend Mr. Greene, I have never been able to find the 

 pupa of this insect, though I have searched for it in localities where I 

 knew the larva was by no means uncommon. The pretty larva is so horribly 

 persecuted by ichneumons that I am induced to think that not one in 

 twenty ever turns to a pupa at all. I have taken the moth at sallow- 

 blossoms in April. (C.) 



85. T. Gothica. — Common of course. The food for the larva, given in the 

 "Manual," is "broom, clover, lilac, etc." It may very [possibly feed on all 

 these, being apparently polyphagous, but they are certainly not the proper 

 plants to search. It is unquestionably a tree-feeder, preferring the oak. 



N.B. — That the larva of this insect ever feeds on broom or clover, as 

 stated in the "Manual," unless compelled, I do not believe. It invariably 

 feeds upon trees or tall shrubs; upon these it is polyphagous. I have fre- 

 quently found a weak miserable ichneumoned larva on the ground, or upon some 

 low-growing plant, but its being there was no choice of its own. It had fallen 

 from some adjacent tree, and was too weak to crawl up again: I never saw 

 a healthy larva in such a situation. (C.) 



86. T. rubricosa. — Taken at sallow-blossoms near Stowmarket, but rare. (C.) 



87. T. instabilis. — Common. 



88. T. populeti. — One solitary specimen at sugar. 



N.B. — The larva of this insect is said in the "Manual" to be unknown, 

 but is described by Mr. Doubleday in the "Zoologist," page 5436, who both 

 bred it from the egg, and took it on aspen. It also feeds upon the black 

 Italian poplar, under which tree I have dug up the pupa at Stowmarket. 

 I found the larva this year, 1858, June 1st., upon the same tree, when 

 searching for the larva of T. subtusa. When young it closely resembles this 

 last-mentioned larva, and spins itself up in the same way between two leaves, 

 or by uniting the edges of one. When full-fed its semi-transparent appearance 

 reminded me strongly of the larva of C. or, but its blackish head was a 

 distinct character. It is, however, extremely unlike the larva of the other 

 Teniocampce. The pupa is very similar to that of T. gothica. (C.) 



89. T. stabilis. — Very common. 



90. T. munda. — Two at sugar.
