This species affects the genus Tringa and other small waders 

 e. g. Strepsüas; Calidris etc. We have seen it also from '^AegiaUtis'' 

 and Äka — probably a straggler in both instances.

Gjanoyri. K. Scheeibee leg. 



The most interesting Nirmus of the collection, remarkably long 

 and Lipeuroid in appearance. 



PiAGET (Les Pediculines, p. 175, tab. 14, flg. 9, 1880) describes 

 and figures a very narrow Nirmus hicolor from Vanellus vulgaris and 

 gives Phalaropus lohatus as a second host remarking only that 

 the parasite of Phalaropus is "nn peu plus long". To Nirmus hicolor 

 Evans ascribes specimens identical with Dr. Dampf's (J, taken on 

 Charadrius hiaticula in the "Forth" Area, Scotland (in : Trans, and Proc. 

 Roy. phys. Soc. Edinburgh, Vol. 18, No. 4, p. 272 (1912). 



We have known this Nirmus now for three vears and belle ve 

 that, so far as Scotland is concerned, it is peculiar to Charadrius 

 hiaticula. The determination, N. hicolor P., does not satisfy us but 

 this Nirmus agrees almost perfectly with N. hoephilus Kellogg 

 {Oxyechus vociferus) (New Mallophaga, pt. 1, p. 107, tab. 5, flg. 7, 

 1896) differing only in the presence of a long reflexed hair in the 

 eye. Such a difference of real would be important but hairs are 

 easily detached and this may well have happened to the unique $ 

 on which Kellogg bases his species. 



N. hoephilus also impresses one with its Lipeuroid facies for 

 Kellogg remarks: "Packaed's outline figure and incomplete des- 

 cription of Lipeurus gracilis, host? (in: Amer. Natural., Vol. 4, p. 95, 

 tab. 1, flg. 6, 1870) raust refer to a form resembling in shape and 

 markings at least this species." 



We believe we have seen specimens of this insect taken long 

 before 1870, and it is our Impression that Piaget may have had it 

 before him also. For in discussing the hosts of Lipeurus baculus N. 

 he remarks: "J'ai trouve des femelies egarees sur une Sula cdba; 

 sur un Totanus glottis; et sur un Charadrius minor, seulement dans 

 le dernier cas les appendices du clypeus manquaient, le dernier 

 Segment avait les lobes plus aigus et les dimensions etaient moindres 

 (171/2)" (Les Pediculines, p. 305, 1880). Evidently Piaget feit some
