THE CANADIAN ENTOMOLOGIST. 13 



The second volume contains the Pterigraphia Americana on 20 plates 

 (Ferns, Mushrooms, etc.), published perhaps 1708. There are many 

 insects, mostly from , the Antilles. But there are also a number of un- 

 doubtedly N. American insects among them.

NOTES ON APHIDID^. 



BY JOSEPH MONELL, E. M., ST. LOUIS, MO. 



Aphis lonicer^e Monell. Riley & Monell, Notes on the Aphididre, 

 U. S, Geol. and Geogr. Survey, Vol. v., Jan., 1879, p. 6. 



This species is the one mentioned by Prof Thomas in the eighth 111. 

 Ent. Rept., p. 104, under the name of Chaitophorus lonicerce Mon'l Mss, 



Phorodon mahalek Fonsc. This European species has been very 

 abundant at the Missouri Botanical Gardens, St. Louis. I believe that it 

 has not before been definitely reported as occurring in the United States. 



Chaitophorus Smithi^e Monell, 1. c. p. 32. 

 Chaitophorus salicicola Thos. 1. c. 



Callipterus Koch. 



Continued study of this genus has confirmed me in the opinion that 

 the subdivision proposed by Passerini is impracticable. In this I am 

 confirmed by Prof. Buckton in his valuable work on the British Aphides. 



C. ULMiFOLii Monell, 1. c. p. 29. 



C. ulniicola Thos. 1. c. p. iii. 



C. (Myzocallis) hvperici Thos. 



This species was previously described by me as Aphis hyperici 1. c.
