1917- ] P- VAN DER GooT : N otes on Indian Aphides. 183 



Morphological characters. — Body robust, head and thorax with 

 numerous, fine, very long hairs, the abdomen less hairy. 



Antennae about 1/3 the length of the body, with numerous, 

 fine, long hairs; relative lengths of the four last antennal joints 

 about as: 35. 17. 19. 17. Sensoriae are present as follows: III 

 I — 2. IV I. V i + i. VI I (+4). vSecondary sensoriae circular, 

 moderately small, of about the same size as the primary ones. 



Rostrum reaching to the third pair of coxae. 



Siphunculi broadly conical, but little elevated above the level 

 of the body. Cauda obsolete. 



Wings with the typical Lachnus-v ervAtion ; media i, however, 

 only once forked. 



Legs fairly long, with numerous fine hairs. (Described from 

 a single winged female with damaged hind-wings). 



Food-plant unknown. 



Locality. — Phagu, 9,000 feet, Simla Hills, W. Himalayas; 18- 

 V-1916 {N. Annandale and S. Kemp). 



Type in the collection of the Indian Museum, Calcutta; No. 

 3825/H. I. 



Although described from a single specimen only, I feel. little 

 hesitation in considering this a distinct species. It shows some 

 resemblance to Lachnus pineti, Koch, but is sufficiently different 

 in the distribution of the sensoriae on the antennal joints, as well 

 as by media i being only once forked.
