 ? , somewhat distorted, evenly brownish, with the segmental interruptions brighter. 

 On the left an intimation of an anal clasp in the form of quite a small tuft of hairs 

 apparently resting on a little plate of chitin. Left antenna 3 , right $ , although 

 rather more strongly developed than in the normal ? . Wings in shape and form 

 ? , forewings brightly coloured as in the 3 , as regards the size and shape of the 

 ocellated spots and other markings ? . Hindwings deep dark orange, alike in size. 

 On the underside the left forewing is brighter orange-coloured ; on the right this 

 colour is less marked, just as the waved marking on the left is far more weakly 

 expressed than on the right side. The hindwings below are quite even in coloration, 

 and correspond with those of a quite darkly coloured 3. Bred in 1829 by Gross.

a — £'. Frings notes (Soc. Ent., ix., p. 182) that a ? -5". pavonia found at 

 Bonn, in 1889, laid many eggs, from which over 100 imagines were obtained in the 

 spring of 1890 ; a few pupae going over until 1891, when they emerged ; among the 

 latter no fewer than six gynandromorphous examples. Three of these are described 

 as follows : (1) A perfect gynandromorph, the body exactly divided from the head to 

 the anus into two halves, showing respectively male and female characters which 

 include even the genitalia. The wings are very curiously divided in a diagonal 

 manner, so that the right forewing and the left hind wing have male coloi'ation, and the 

 left forewing and right hindwing are coloured as in the female. The male and 

 female wings, as well as being ditferent in colour, have the usual disparity in size, 

 giving the specimen, which is well developed and as large as a middle-sized female, 

 a very curious and beautiful appearance. (2) An apparently faultless female, of 

 medium size, but with both antennae pectinated as in the male, and the costal border 

 of the right fore- and hindwings decidedly male with orange coloration. (3) The 

 upper surface of all four wings is of male coloration, but the right wings are 

 considerably larger than is usual in the male. The right wings are greyish below as 

 in the female, while the left wings have male coloration on the under surface. The 

 abdomen and thorax are of the male form, though the former is swollen with eggs, 

 which can clearly be seen through the spaces between the segments. The genitalia 

 are completely divided into male and female, the male anal clasps being very strong 

 and larger than usual. (4 — 5) Two others of this brood are noted by Caspari 

 (Jahrb. d. nass. Ver. Naturk., xlviii., pp. 172 — 173) as being "of predominant ? 

 type with 3 portions scattered over the wings." 



r\ — X. Five gynandromorphs were bred by Caspari, at Wiesbaden, 1895: 

 (1) Completely divided; left antenna entirely 3 , right ?. Left forewing and 

 left hindwing wholly 3 , hindwing fiery orange ; right side decidedly ? . Underside 

 as the upperside without a trace of 3 and ? admixture, genitalia exactly divided, 

 left 3 , right ?. (2; The second gynandromorph similar, though smaller, with 

 very dull coloration and faint orange on the 3 hindwing. All the wing-scales 

 poorly developed. (3) The body of the third gynandromorph is not divided into a 

 3 and ? side, but exhibits hairs as in a normal 3 . Wings in shape and 

 coloration more 3 , though with isolated places ? -coloured, especially on the 

 underside. Left antenna wholly 3 , the right half ? . The upper side of this (right) 

 antenna without pectinations, the underside with distinct 3 pectinations. Abdomen 

 3 , with 3 genitalia. (4) The fourth is a perfectly divided gynandromorph, 

 except a slight blending. Left antenna strongly pectinated as in the 3 ', 

 right below 3 pectinated, above as in the ? , except a few small weak pectina- 

 tions towards the apex of the antenna. Left wings above and below very 

 fiery-coloured; right wings ? , except a place on the forewing from the first lower vein 

 to nervure 4. The abdomen above is 3 , more marked towards the left side, below ? 

 more marked towards the right side. The body somewhat crooked, right side longer 

 and stouter ; full of eggs. (5) The fifth gynandromorph exhibits on the right a ?, 

 on the left a 3 , antenna. The body is only divided on the lower part of the thorax, 

 while the abdomen is entirely ? and filled with eggs.
