The Desmodium Aphid, Microparsus variabilis n. sp.~* 



EDITH M. PATCH. 



(Plates XVIII and XIX) 



For the past few years a very distinctive aphid has been pres- 

 ent in enormous numbers upon the Canadian tick-trefoil in the 

 vicinity of Orono. On account of the size of the wing tracheae 

 and the abundance of material this was one of the species 

 which the writer used in the study of wing venation and it was 

 figured and named in that connection before the description of 

 the species was put into shape. Although not as detailed as is 

 desirable it is hoped that the description given here will serve 

 to place this characteristic species.
