EASTERN APHIDS, NEW OR LITTLE KNOWN, PART I^ 

 By Edith M. Patch 



The present paper resulted from the examination of the collection 

 of Connecticut aphids lent by Dr. W. E. Britton. Several undescribed 

 species were found, some of which were well known in certain collec- 

 tions without having made their way into literature. A few of these 

 are briefly described by the writer of Part I, and the others are presented 

 by INIr. Baker in Part II as he was already at work on the groups those 

 species represent, and kindly undertook their examination. 



Most of the species are described with reference to material from 

 Connecticut, though a few not yet reported from that state are included. 



Aphis viburniphila n. sp. 

 (Fig. 20, c, d, e) 



Alate Vivipara: Head, eyes, and antenna black, antennal joint III and VI 

 approximately same length and sub-equal to IV + V, III with about 20 sensoria ex- 

 tending whole length, IV with from none to several sensoria, beak extends to second 

 coxae; thorax black, prothoracic tubercles prominent, wings with rather heavy dark 

 veins; abdomen glabrous, dark red to reddish brown both above and beneath, caudal 

 portion black, four lateral dusky spots cephalad of the cornicles, cornicles cyhndrical, 

 black, about twice the length of tarsi, imbrications serrate; cauda and cornicle, black, 

 paler at base; lateral tubercles present, that between cornicle and cauda being 

 prominent. 



Apterous Vivipara: Head black, antenna dark except proximal III which is 

 pale. III with, about 1.5 sensoria which are more numerous on distal half, IV with or 

 without sensoria; thorax reddish bro^\Ti with prothoracic tubercles: abdomen bright 

 reddish l^rown with two transverse black stripes cephalad the cauda, cornicles and 

 Cauda black. 



Apterous Ovipara: Tan-colored form with black cornicles which are slightly more 

 than half as long as in the apterous vivipara; antenna without secondary sensoria; 

 hind tibia but sUghtly enlarged with a very few sensoria on distal half. 



The cotype localities are Orono, 'Maine, where the writer has 

 collected this interesting aphid for ten years; New Haven, Connecticut, 

 where it has been taken by Dr. W. E. Britton and Mr. H. D. Clark; 

 and Plummer's Island, Maryland, and Great Falls, Virginia, where 

 Mr. W. L. McAtee has collected it, specimens from all these places 

 being examined at time of preparing the description. Mr. J. J. Davis 

 writes (March 22, 1916) that he has this species from St. Louis, and 

 from Chicago where it is sometimes a serious pest of the Viburnum in 

 parks. 



In Maine this species is present on Viburnums during the entire year, 

 being conspicuously abundant during June, July and August. It
