THYRIDAE. 



i. Thyrus maculata Harris. Rare, on bramble blossoms ; June- 



ZYG^ENIDAE. 



i. Alypia octomaculata Fabr. Not common ; June, July. 



2. " Langtonii Couper. Rare ; June. 



3. Eudryas unio Hubn. Rare ; July. 



4. " grata Fabr. Not uncommon ; July. 



5. Scepsis fulvicollis Walk. Very rare ; taken by Messrs. Couper and 



Pearson ; June, July. 



6. Ctenucha virginica Charp. Very common ; end of June, July. 



7. Lycomorpha pholus Harris. Not uncommon ; August. 



Notes. — These are all the species that I have seen from this locality 

 Mr. Knetzing informs me that he found a larva of Deilephila lineata Fabr., 

 but did not succeed in rearing it. Mr. Couper was told by a friend last

 plot in the outskirts of the city. These were probably larvae of Macrosila 

 quinquemaculata Haw. I am of opinion that when proper attention has 

 been given to the larval stages of these groups, many species will be 

 added to this list, and many species that we think are rare will prove to 

 be comparatively abundant.
