this constitutes a genus distinct from Greenidea, although 

 closely related to it. 



The characters of this new genus are : Antennae of migrant 

 as long or longer than the body, composed as usual of six 

 joints, all of which, excepting the two basal, are furnished 

 with long and bristle-like hairs, the third being longest. Front 

 of head broad and quite straight ; posterior tubercle of eyes 

 bearing three ocelli. Abdomen sparsely hairy. Tail short 

 and broadly triangular. Nectaries very long, almost as long 

 as the whole body, cylindrical, straight, curving outwards 

 towards the apex and profusely covered with long, bristle- 

 like hairs. Venation similar to that of Aphis. 



In the apterous female, the whole body, including the an- 

 tennae, nectaries and legs, is covered with stout hairs or bris- 

 tles ; head, etc., as in the migrant. Nectaries short, or about 

 one-fourth of the length of the body, stout and distinctly fusi- 

 form ; curved outwards. 



Only two species exhibiting these characters are thus far 

 known to me. The first of these represented by migrants, 

 pupae, apterous females and larvae, was discovered by Dr. L. 

 Zehnter, January 10, 1902, at Salatiga, Java, on Anona nniri- 

 cata. Following is its description : 



Trichosiphum anonae n. sp. 



The material representing this species was, as usual, pre- 

 served in alcohol, and for this reason the original coloration 

 has vanished. It appears, however, to have been yellowish 

 green in the migrants, with the exception of the greater part 

 of the abdomen above, which appears to have been brown. 



Migrant. Antennae 6 jointed ; the two basal joints, as usual, shortest 

 and subequal in length, the first joint stoutest ; joint 3 longest, longer 

 than the spur of the sixth joint and but slightly shorter than the fourth 

 and fifth combined, both of the latter subequal in length ; all of these 

 joints are furnished with rather long and stiff hairs ; there are also from 

 four to six small, transversely oval sensoria near the base of joint 3. The 

 antennae are slender and about as long as the whole insect. 



Front of head quite straight, slightly indented about the middle, and 

 furnished witli about six long and slender hairs, while similar hairs are 

 scattered over the upper surface of the head. 



Head broader than long, and, with the eyes included, broader than the
