of the insect ; joints 3 and 6, including the spur, longest and subequal in 

 length, each of them about as long as joints 4 and 5 combined ; the fifth 

 slightly longer than the fourth ; all, except the spur, are provided with a 

 few long stiff hairs or bristles. Tail and end of body as in the migrant ; 

 nectaries much shorter than in either the migrant or pupa, or only about 

 one-fourth the length of the body, rather stout near the middle, tapering 

 toward each end and curved outwards. Abdomen without spots, the 

 whole body, including the nectaries and legs, profusely provided with 

 stiff hairs or bristles, similar to those of Chaitophorus. Length about 1.4 

 mm.; diameter across the abdomen about 0.8 mm. 



Trichosiphum kuwanai n. sp. 



Among the material of aphids sent by Mr. S. I. Kuwana, of 

 the Imperial Agricultural Experiment Station, Nishigahara, 

 Tokio, Japan, were found three parcels of alcoholic specimens 

 of apterous females, larvae and a few pupae of this species, 

 though none of the migrants. All were found living upon 

 Quercus serrata on the 27th and 2Qth of June, and on the 2nd 

 of August, 1905. Those taken in June are stated to be of a 

 deep black color, whereas those obtained in August are said 

 to be reddish brown. An examination of the entire material 

 convinces the writer that all of them belong to the same spe- 

 cies, which he herewith takes pleasure in dedicating to Mr. 

 Kuwana. 



This is, therefore, the second female, in which the nectaries 

 of the apterous females are short, stout and fusiform. 



Apterous Female. Antennae about one-half the length of the body; 

 joints 3-6, including the spur, varying more or less in length in different 

 specimens and frequently in the same individual ; the third joint as usual 

 is longer than the two following joints combined, the latter subequal in 

 length. All of the joints, excepting the spur, are provided with long, 

 stiff bristles. Front of head broad and quite straight. Eyes large, their 

 posterior tubercle much elongated and bearing three large ocelli at the 

 end; sides of the thorax quite straight, broadening more or less distinctly 

 posteriorly, while the abdomen is almost circular in outline. The legs 

 are rather long and stout, and like the rest of the insect, profusely cov- 

 ered with stout stiff bristles. Nectaries usually somewhat longer than 

 the third antennal joint, or about one-half as long as the abdomen, stout, 

 tapering toward each end and curved outwardly, covered with numerous 

 long bristles and minute spines. 



Tail short, broadly triangular, bearing a short triangular point at the 

 centre of the posterior edge, densely covered with minute sharp points 

 and furnished on each side with three or more long stout bristles. Last
