Suborder Ischnocera. 



Tricliodectidae. 



Tricliodectes colobi n. sp. 



(PI. 7, tig. 1.) 



Many specimens, males, females, and young from the monkey Colobus caiidatus. 

 The first Mallophagan specjes to be recorded from the Quadrnmana. 



Male. Body, length 1.8 mm., width 0.66 mm.; pale, abdominal marklngs few 

 and weak, head as long as broad and with emargmate clypeus. Head, length 5.3 

 mm., width 0.57 mm.; rather markedly hexagonal with anterior (clypeal) margin 

 distinctly emarginate though not deeply; antennse with first segment very large and 

 strong; no well-defined markings, the Ught brown mandibles showing through, and 

 the antero-lateral margins chitinized althongh not colored. Prothorax narrow and 

 short; quadrangular with posterior margin straight. Metathorax wider than protho- 

 rax with well marked projecting medio-lateral angles reaching laterally nearly as far 

 as postero-lateral angles of first abdominal segment; posterior margin flatly rounded. 

 No thoracic blotches or other distinct markings. Abdomen elongate elliptical to 

 ovate, with crenulated lateral margins, and narrow uncolored, translucent borders, 

 but without blotches or other distinct markings; posterior segment narrowly rounded; 

 a sparse covering of short spinous hairs over body but no long hairs; a row of very 

 small stiff spines along the posterior margin of each of Segments 2—6. 



Female. Slightly larger than male, with the abdomen broadly truncate behind, 

 and the crenulation of the lateral margins more pronounced. The antennae are 

 slender with the first segment no larger than 2^<^ or 3'''^. No distinct markings. 



Kilimand'jaro : Kibonoto, rain-forest, 2000 m. 



Tricliodectes iuibciualls Piaget. 

 Numerous specimens, males, females and young, from Mungos {Herpestes) caffcr Gm. 

 Piaget's specimens were taken from Herpestes ichneunwri, Zool. Garden of Rotterdam. 

 Kilimandjaro : Kibonoto. 



Pliilopteridae. 



üocopliorus episcoi»! n. sp. 



(J'l. 7, tig. 2.) 

 One female from Herodias alba, five females from Ephippiorhynchus and numerous 

 males and females from Dissoura episcopus or microscelis. A well marked form of the 

 group sefosi, characteristic of storks, distinguished by the curious fused double 

 signature with its strongly chitinized protuberant posterior tips, and the very distinct 

 straight clypeal suture. Much Uke, and evidently closely allied to Piaget's D. indicus 

 from Tantalus lacteus (Java) and D. unijasciatus coUected from Polyborus vulgaris but 

 considered by Piaget as undoubtedly a straggler from some species of stork or egret. 

 The African specimens differ from unijasciatus in being of smaller size, having the 

 abdominal blotches markedly larger, and the vulvar appendages not apparent.
