of one honey tube to the other, is of a reddish tint. Lyes black; 
wing cases of the pupa black. Fig. 14 shows to the right a highly- 
magnified view of the right eye; at the top is an enlarged figuie of

SlPHONOPHORA LACTUCLE. Linn? 
There is much confusion in reference to the species of plant-lice 
inhabiting the common garden Lettuce; and it is at present, perhaps, 
impossible to identify the species named by Linmeus. Kaltenbach, 
Koch, Walker, Passerini and Buckton differ so greatly that not more 
than two out of the five authors agree on any one species. As the 
only specimens I have discovered were wingless, 1 am unable to de¬ 
termine amid this confusion, to which it belongs, and will therefore 
give briefly the descriptions by these authors so far as I have them at 
hand. 
Koch’s figure and description shows his species as follows : ^ize 
slightly above medium. 
"Winged-female. —The head, antenna*, a large dorsal spot on the latter 
part of the abdomen, and the honey-tubes black; eyes, thorax and 
front and sides of the abdomen a bright reddish-brown; legs yellow, 
with the tarsi and tips of the femora and tibia? dark; tail pale yellow. 
Antennae extending slightly beyond the tip of the abdomen; honey- 
tubes rather long; tail short and slender. 
Wing less-fern ale. —Somewhat larger. Antennae and eyes black; head, 
thorax and abdomen bright reddish-brown; on the disk of the abdomen 
there is a large black spot with the central and larger portion of it 
pruinose or gray, and its lateral margins fringed by black; honey-tubes 
very long, slender and black; tail rather long and yellow; legs as in the 
winged female; the abdomen is slightly hairy, especially at the sides. 
Kaltenbach states that this is his Siphonophora sortchi which he 
makes identical with A. sonchi. Linn.
