54 THE ENTOMOLOGISTS RECORD, 



simple and furcate : on the body some are more broadly expanded apically, others 

 slightly capitate ; cauda pale, rounded, with four long pale hairs and some 

 median shorter ones, notched at the sides, and from each notch arises a long hair. 



Length. l'5mm. to 2mm. 



Locality. Sandown, Isle of Wight, 24 viii. 1908 (Donisthorpe). 



Notes. Described from two 5 s taken in the nest of Mi/nnica 

 laevinodu. It can at once be told by the form of the hairs. The 

 antennal structure certainly places it in Forda, and approaches that of 

 F. viridana, Buckton. The siphon openings are quite level with the 

 body. 



Aphis alienus, nov. sp. 



Apterous viviparous female. Bright emerald green. Eyes large, dark. An- 

 tennae shorter than the body, of six segments, the fifth dusky at the apex and all 

 the sixth ; first segment broader and slightly longer than the second ; the third 

 longer and narrower than the second ; but often not quite as long as the fifth ; the 

 fourth about one-third the length of the third, and about equal to the length of 

 the first two ; fifth slightly longer than the third, up to the long " nail," about as 

 long as the fourth ; the first and second slightly darker than the third and base of 

 the fourth; the fourth and fifth markedly imbricated, the third on the apical half 

 only ; edges serrated, a few scattered hairs on all the segments. Proboscis dark 

 at base and apex, reaching to the third coxa. Prothoracic ring with blunt lateral 

 processes. Abdomen with one lateral blunt papilla on each side, between the 

 second and third pairs of legs and another between the cornicles and cauda. 

 Cornicles rather short, black, thick, expanded basally, marked with dotted lines 

 instead of true imbrication, about as long as the cauda, which is dusky especially 

 at the apex. Legs moderately long, especially the hind pair, the tarsi and apices 

 of the tibiae dusky ; femora with a few hairs ; tibiae with many ; last tarsal with 

 serrated edges and markedly Imbricated. A large, marked papilla on each side of 

 the Cauda, between it and the cornicles. Penultimate segment of the rostrum 

 swollen. 



Length. 1mm. to TSmm. 



Locality. Seaton, South Devon, 2 viii. 1912 (Donisthorpe); Whit- 

 sand Bay, Cornwall. 



Observations. Found in the nests of Lasius alienus. 



It is one of the smallest Aphides I have seen. It approaches 

 Walker's Aphis subterranca, but can at once by told by having antennae 

 composed of five, not six, segments in the apterous female ; the 

 cornicles are also relativelj'^ longer and of different shape being much 

 expanded basally, they are also black whilst in subterranea, they are 

 only black at the tips. The antennse and legs are also thinner than 

 in Walker's species. Nor is it Koch's Aphis carrotae, which Buckton 

 and others take to be subterranea, for Koch's species has a dark head 

 and dark cauda and also antennae of six segments and shorter cornicles. 

 I have not found alatae of Aplris carrotae, but judging from the apterae 

 it is distinct from subterranea and the one I describe here. 



Aphis leontodoniella, nov. sp. 



Apterous viinparous female. Very pale yellowish-green all over. Eyes large, 

 deep black, edged with red. Head with a depression on each side, raised in the 

 centre, with numerous longish pale hairs. Antennne pallid, thin, half the length 

 of the body, of six segments, the basal one large and broad, the second narrower 

 and slightly shorter, the third long, but not as long as the sixth ; the fourth rather 

 more than half the length of the third, the fifth slightly shorter to nearly as long 

 as the fourth, longer than the basal part of the sixth, which has a very long thin 

 " nail" ; all segments with prominent long thin pale hairs ; a sensorium near apex 

 of fifth and some faint ones at the base of the " nail," which is markedly striate 

 and serrated at the edges. A distinct large rounded process on each side of the 

 pronotum and five smaller ones on each side of the abdomen, which has very small,
