mens of the host species. It is on the basis of such intensive collec- 

 tions as these that anything like an inclusive knowledge of the re- 

 lation of the Mallophaga to any given host must be based. 



The types of the new species described in this paper are in the 

 Indian Museum, Calcutta. 



The writers wish to express their recognition of the courtesy 

 of Superintendent Annandale in permitting them to examine so 

 interesting a Mallophagan collection. 



I. MALLOPHAGA FROM PHASIANIDAE. 

 Nirmus nigromarginatus, Piaget. 

 One female from G alius sonnerati (no history^ India). 



Goniocotes indicus, n. sp 

 (Plate xiv, fig. 4.) 



One male specimen from Arboricola nifigularis (Jorpokri^ East 

 Himalayas). A bright-coloured, prettily patterned new form with 

 rounded lateral margins and conspicuous, straight, backward-pro- 

 jecting posterior angles on the head. The figure represents the 

 insect as somewhat too dull, the abdomen especiall}^ appearing 

 considerably brighter in the specimen. This is a large species for 

 Goniocotes . 



Description of male: Head rounded, inflated, with broadly 

 rounded front whose sides are somewhat flattened. General colour 

 a rather bright yellow with reddish brown mandibles and mark- 

 ings. Antennal bands pale, continuous around the front, w.here 

 they are widest, and turning in, as usual, before the antennae, 

 though not much darkened at this point. Six fine hairs on each 

 side on the front, the forward two being submarginal. There is a 

 clearly defined, dome-shaped, semi-transparent space in front of 

 the mandibles. Antennae well developed with second segment 

 longest and fourth shortest; third and last segments about equal, 

 basal second in length and thickened ; colour a little paler than 

 head. Triangular projecting area directly before antennae with 

 surface appearing as though finely pitted. Eye large, but slightly 

 protruding with a fairly long hair and large, granular fleck ; ocu- 

 lar blotch quite dark with distinct margins. Temples convex in 

 front, concave behind, with posterior angles acute and projecting 

 straight backward nearly half the length of the prothorax and 

 bearing a minute spine. Two long, pustulated hairs on the lateral 

 margins of the temples behind the widest part and a short spine 

 nearer the eye. Marginal bands little coloured, except close to 

 the eye, and completely ifiterrupted for the reception of the 

 marginal hairs. Occiput sinuous, with marginal band, darker at 

 each side, where it forms the ocular blotches. Occipital bands and 

 signature lacking. 



Thorax shorter than head and narrower, also slightly darker in 

 general tone with rather broad marginal bands. Prothorax with
