the/emale forms. The specimeus figured are from near Dorey, Dntcli New (ininea. 

 In f. 166 the left lateral ridge is not drawn ; tlie ventral process of this 

 specimen is at the aj)e.\ much deeper sinuate than that of f. 104, and the lateral 

 process is much broader and multidentate, while the process is not dentate in 

 f. 163 and 104. The anal segment and the supravaginal tubercle t is represented 

 by f. i:0. 



b. P. aegeus aegeus : f. lOT to lO'.i. 



The female, of this subspecies is monomorphic in colour and pattern. The 

 variability of the vaginal armature is illustrated by f. 167 to 169. The ventral 

 process is slenderer at the base than in aegeus ormenus, and the lateral process 

 has mostly on the outer side a slightly raised carina (f. 108 and 160). In f. 107 

 the teeth of the lateral and ventral processes, and in f. 10!) those of the lateral 

 process, are mostly obliterated ; the dentition of the lateral process represented 

 in f. 168 is restricted to the upper edge. 



20. Papilio rumanzovius ; f. 1 70 and 1 78. 



There are four series of species of Papilios whicli are closely allied to one 

 another, tlie groups of P. mcmnoii, P. acgrm, P. di'iphohus, and P. lampmcua. We 

 represent for comparison the female sexual armature of a species of the first three 

 groups; the close relationship of the insects in question finds an expression in tlie 

 similarity of the genital armature oi male itudjemale. 



F. 170 is taken from a specimen of P. rumanzonus ?-f. rumanzni-im. The 

 ventral jjrocess is broadest towards the base, its ajiex is irregularly truncate, 

 the dentition of the process of aegem (f. 166 to 169) is absent ; the median keel 

 on the ventral side of the process of aegeus is here separated into a number of 

 irregular, longitudinal, slightly raised folds and wrinkles. The lateral ])rocess is 

 less high and leans over dorsally. The supravaginal tubercle, which in aegeus 

 (f. 176) is small, and near whirh the membrane is inobviously folded, is in 

 rumanzovius large (f 17S), iin<l rhc membrane between it and the anal segment 

 (ix. + X.) is regularly and heavily folded transversely, the folds being limited 

 laterally by a longitudinal fold. 



21. Papilio memnon; f. 171 to 17.5, 177. 



Like I', polijfi'x and /''. aegeus oimeuHS, this species has a polymorphic /ewafe 

 in most localities; we have examined a number of tailed and tailless individuals from 

 Korfli India, Java, Nias, and Borneo, and come to the same conclusions as in the 

 case of the two before-mentioned Papilios, that the subspecies are extremely 

 slightly different in ihi? female genital armature, and that the various forms of the 

 female of each sub.species do not e.\hil)it any (characters in the vaginal apparatus 

 peculiar to one or the other of the forms. Tlie individual variability is as great, or 

 even greater, than in ormenus. 



The chief features by which the vaginal armature of memnon can be distin- 

 guished from tliat of aegeus, to which it comes rather near, are as follows : the 

 ventral process is broader basally, and tlie median keel of the underside (ventral 

 side) is widened out laterally into two ridges wjiich rise under a small angle from 

 the plane of the main process (f. 173, m). The lateral process (J)) is higher 

 than in /'. aegenx. and divides very often at its ilorsal edge in an outer (f. 174 and
