 p. 18). 



1. Left side J , right ? . Brightly coloured example. Median line 

 indistinct. All the wings of the same size. Left antenna <? , right ? . Body 

 large, ?, with 3 down. Gleissner coll. (Schultz, ///. Woch. fur Ent, i., 

 p. 368). 



k. Right side $ , left ? (Fischer-v.-Waldheim, Oryctogr. de Mascot/,

X. Right side g , left ? . 1887. Cologne. Westkamp coll. (Ent. Zeits. 

 Guben, i., p. 50). 



ft. Left side cf , right ? . On May 24th, 1893, rom a pupa which had been 



kept all the winter, an imago emerged which, on its left side had a $ antenna 



and a small S forewing, whilst on the right side it had a ? antenna and a large 



S forewing. The hindwings were crippled (Brown, Ent. Mo. Mag., xxix., p. 



165). 



v — £. Amongst a number of S. ftopuli I am now (April 16th, 1880) rearing 

 from pupae, I find two hermaphrodite specimens, each having a $ and a ? 

 antenna. -One of these is depositing eggs (Shuttleworth, Ent., xiii., p. 116; 

 E. M. M., xviii., p. 167 ; Proc. Ent. Soc. Lond., 1880, p. xxx). 



0. Left antenna S , right antenna ? . Left iorewing and right hindwing 

 light in colour, the two other wings marked with darker (Seydel, Ent. Zeitsch. 

 Bredau, 1886, p. xxvii). 



7T. Left side <? , right side ? . Division sharp on head, left antenna $ , right 

 ? , eve and palpus on left side larger, with longer hairs. On the right the epaulette 

 is darker, both wings on this (the ? ) side much more intense in colour, sharper 

 marked, less emarginate, and larger. In the outer area of cells i — hi of the right 

 ( ? ) forewing, irregular dark-brown male stripes run through the violet-grey ground- 

 colour. The left (<?) front leg is far shorter and more strongly clothed with hair 

 than the right. The abdomen is very interesting in form ; dorsally and laterally it 

 is purely S in clothing and colour ; ventrally, however, it has many irregular patches 

 of ? coloration and with short hairs ; it is also strikingly long and thick, of the 

 size of that of a large ? , right side much more strongly ventricose than left, with 

 purely normal g external genitalia, which were examined in the fresh moth. The 

 specimen is very large, of a fine violet- grey colour on both pairs of wings, in spite of 

 the unlikeness in other respects of the left and right sides. The pupa-case distinctly 

 shows the difference of the antennal sheaths. The pupa came from the neighbour- 

 hood of Leipzig. Imago bred April 30th, 1900 (Frings, Soc. Ent., xv., pp. 52—53). 



p — a. We have twice, in the neighbourhood of Paris, met with a poplar Sphinx 

 which had, at least externally, the characters of a gynandromorph (Godart, Encycl. 

 Meth., ix., p. 66). [No further details are given. Godart had been describing a 

 gynandromorphous Fapilio ulysses, and just mentions these incidentally to show that 

 the occurrence was not unique.]

\p. Right side $ , left side ? . Left antenna ? , right antenna $ . Both
