﻿SOME N0TK8 ON THE PAPILIONIDS. 275 



9. Macrosiphum lamii, nov. sp. 



Alate viviparous female. — Head and thorax yellowish-green to 

 yellow ; thorax with brownish lobes. Abdomen bright green in 

 front, yellow to orange posteriorly; with rather indistinct darker 

 green lateral spots. Venter green ; mesosternal plates palo brown 

 Antennas longer than the body, dark brown ; base of third segment pale, 

 Cornicles pale, dark at the apex. Legs fawn-coloured, apex of the fe 

 mora, tibige and tarsi, black. Wings with dark brown veins and stigma 



Antennae arising from prominent frontal processes, two basal seg 

 ments pale, the first longer than the second; the third longer than the 

 fourth, with 13-16 sensoria, more or less in a straight line, and more 

 or less extending to the apex of the segment ; fourth segment longer 

 than the fifth ; sixth not as long as the fourth and fifth. Proboscis 

 reaching to the second pair of legs, green ; apex black, rather thick. 

 Cornicles narrow, cylindrical, shorter than the third antennal segment, 

 with one or two laterally branched transverse striao at the apex, rest 

 imbricated. Cauda green, prominent, with three pairs of lateral 

 hairs and one median dorsal one near the apex, less than one-third 

 the length of the cornicles. Length, 2 mm. ; wing expanse, 9 mm. 



Food Plant. — The red lamium {Lamlum purpureum) . 



Locality.— Wye, Kent (June 8th, 1914). 



Observations. — Described from some alate viviparous females 

 which were found producing their young in isolated colonies. 

 The larvae varied from pale to deep green. No apterous vivipar- 

 ous females could be found. They were found amongst the 

 flowers and under the leaves. 



10. Kaltenbachiella menthce, Schouteden (Mem. d. 1. Soc. Ent. 

 Belg. xii. p. 195, 1906). — This root-feeding aphid, described by 

 Schouteden from the terminal roots of corn mint {Mentha 

 arvensis), was sent me by Mr. J. C. F. Fryer, of the Board 

 of Agriculture, on the roots of water mint (M. aquatica) from 

 Chateris, Cambridgeshire, on September 15th, 1914. All the 

 specimens were apterous females, but one which just showed 

 traces of wing-buds; unfortunately this died. These insects 

 produced much flocculent white wool on the roots, often in little 

 compact patches. It clearly bears strong resemblances to 

 Passerini's Rhizohius menthce. I have this water mint colony 

 still alive, but no alatse have occurred at present.

(9) Papilio alcinous — An account of my experience with this 

 species should have preceded the notice of P. hianor in the last 

 number of the 'Entomologist.' It was for reasons of space 

 onlv that it was omitted. P. alcinous is a native of Japan and
