LEPIDOPTEROUS INSECTS. 
236. Papilio Diceros. 
Papilio Diceros, G. R. Gr. 
Female. PL XI. f. 4. — The primary wings deep black, and the outer margin between the nervules bordered 
with minute lunes of white ; a large round space of white occupies the middle of the wing, which is divided into 
four unequal spots by the median nervure and the first and second median nervules. 
The secondary wings deep black, and the outer margin between the obtuse dentation bordered with white ; a 
broad transverse band of subopalescent crimson at a little distance from the discoidal cell, which is divided into 
six unequal spots ; the two at the anal angle are large and unequal in width, the two next are equal and are 
wider than the rest, while the two next are less, decreasing in size towards the anterior angle. 
The under surface of all the wings is similar in colour and markings to the upper side ; but the transverse 
band of the secondary wings is rosy white covered with darker coloured minute scales, especially on the margin 
of each spot. 
This species is closely allied to P. Tarquinius, Boisd. ; but in this latter species the white space on the primary 
wings is divided into four spots by the median nervure and the second and third median nervules ; the trans- 
verse band on the secondary wings is rather narrower, and it is continued by an additional minute spot of rosy 
white below and close to the first subcostal nervule. 
In Collection (Brit. Mus.) from Para. 
Variety a. Female. 
With the white space in the middle of the primary wings composed of four spots, but the one at the base 
between the second discoidal and the first median nervules is very small. 
The transverse hand on the secondary wings is similar in form to the last, hut it is without the opaline 
appearance. 
Para. 
Variety b. Female. 
With the white space in the middle of the primary wings altogether smaller, though composed of four spots; 
but the one at the base between the second discoidal and first median nervules is rather larger than that repre- 
sented in the figure, while the two other spots below the median nervure are much reduced in size. 
The transverse band on the secondary wings is rather narrower, but similar in form, and there is a minute 
spot of the same colour in the middle between the costal nervure and the subcostal nervule. 
Para. (In the Collection of Mr. Hewitson.) 
Variety c. Female. 
With the white space in the middle of the primary wings divided into four spots ; the one in the discoidal 
cell reduced in size, and the two between, at the base of the second discoidal and the second median nervules, are 
larger than the other specimens, while the spot below the second median nervule is reduced into a very narrow 
streak only. 
The transverse band on the secondary wings is like that of Variety a, but the spot between the second costal 
and discoidal nervules is only slightly apparent.

237. Papilio Cixius. 
Papilio Cixius, G. R. Gr. 
Female. PI. VIII. f. 6. — The primary wings brownish black, with the summit rather clearer, having eight 
minute spots of white scales on the outer margin ; a subquadrate white spot occupies the space at the bases of 
the first and second median nervules. The secondary wings brownish black, with the margin between the 
dentations narrowly bordered with white ; a large space of pale carmine extends from the anal angle to
