THE ENTOMOLOGIST, 



Food Plants. — Mosses {Hypnum si)p.). 



Localities. — Great Witcombe, Gloucestershire (viii, 1902), and 

 Way's End, Camberley, Surrey (6, vi, 17). R. Newstead. 



This is a very marked aphid, twice found by Prof. Newstead. 

 The earher specimens have not been taken as the type owing to 

 their being in poor preservation, but the markedly stumpy legs 

 and antenna3 and the single large, blunt, tarsal segment place 

 them undoubtedly with the last insects found on "Moss" at 

 Camberley. 



So far, this is the only species recorded as feeding on Musci. 

 The very peculiar tarsal structure might place it in the genus 

 Tetraneura, but the short, stumpy, four segmented antennae at 

 once exclude it ; hence I have placed it in a new genus, near

Tetraneura, for which I propose the name Truncaphis. All the 

 ground forms of Tetraneura vlmi, so common in ants' nests, 

 show a marked 5-segmented, antennal structure, and the an- 

 tennae and legs are not nearly as short and stumpy as in this 

 moss-feeding species. 



30. Sipha paradoxa, nov. sp. (Fig. 2). 



Apterous viviparous female. — Elongate and narrow ; yellow, paler 

 beneath ; dorsal scuta much overlapping the ventral ones. Tip of 

 proboscis brown. Eyes dark brown. Antennae yellow, the last two 

 segments somewhat darker. Legs yellow, except apex of tarsi and 

 the rather long ungues which are darker. Antennae very short, 

 longer than head, but never reaching past the pronotum ; composed 

 of five segments, the first larger than second ; the third much longer 

 than the fourth and slightly shorter than fifth to nearly the same 

 length ; base of fifth slightly shorter to about the same length as the
