DESCRIPTION OF THE PUPA CASE OF HEODES DORILIS. 133 



On the second day the colours were much more solid in tone and 

 had become, as time shoAved, the permanent colours of the pupa, 

 previous of course to the general darkening that comes on just before 

 the emergence of the imago ; on the fourth or fifth day after pupation 

 I took the following description of it. 



Eyes, face and two thirds of the antennte dark green, the ventral surface and 

 wing-covers pale yellowish-green with almost imperceptible lines of darker green, 

 the proboscis is also rather darker green, the lateral portion of the pupa above the 

 wing cases is likewise green up to the last segment but one. The upper part of the 

 head is pale pinkish with a blackish dot on each side (? the sockets of the antennas) 

 the space between the top part of the eyes is paler and separated from the rest by a 

 pale crescent. The thorax is greenish tinged with pink, with a dark green central 

 line, on each side of which, in the centre, is a dark spot; on each side of the thorax 

 before the suture of the wing cases, is a series of three dark dots ; the dorsum has a 

 broadish central darkish pink line, on each side of which is a broad pinkish-white 

 stripe interrupted at the segments, these are succeeded by a broader darkish pink 

 stripe, also interrupted at the segmental divisions, edged by a fairly broad white 

 stripe, on the lower edge of these white stripes the spiracles show as dark points 

 ending in a triangular series of three just behind the thoracic shield ; below and 

 behind the spiracular dots is a fine dark short diagonal dash on each abdominal 

 segment from the third to the sixth, inclusive. The whole of the dorsal surface is 

 densely covered with very fine short setae, the lateral part of the abdominal surface 

 being less densely covered. 



The larva pupated on July 22nd, and a nice bright female emerged 

 at home on August 10th. 



I sent the empty pupa case to my friend Dr. Chapman who has 

 kindly given me permission to publish his description of it. 



Description of the Pupa Case of Heodes dorilis. {With tn-o plates). 



By T. A. CHAPMAN, M.D., F.Z.S., F.E.S. 



Specimen of empty case. The front of the thorax is by dehiscence 

 expanded laterally and shortened dorso-ventrally, partly (the former 

 chiefly) by separation of the two sides, partly (chiefly the latter) by 

 curling of the separated portions. 



The pupa is 10-5mm. long, of which only 1-8 is behind the wing 

 and antenna cases. The height (3rd abdominal segment) is 4-Omm., 

 the width 4-5mm. at the same place ; when alive it obviously 

 narrowed forwards of this in both directions fairly equally, now it 

 does not narrow across, but is reduced dorso-ventrally to 2mm. at 

 front of mesothorax. 



The colour is pale yellowish -grey, with many black spots and dots. 

 The most regular of these form a dorsal row, one in middle of each 

 segment ; a dorsal row, one behind middle of each segment ; a supra- 

 spiracular row of slightly larger dots, and the hind abdominal seg- 

 ments show a subspiracular and two ventral rows. There are very 

 numerous minute dots generally scattered amongst these ; the wings 

 show irregular dark markings of more or less coalescent dots, that 

 avoid the lines of nervures. The head is so clouded as to be nearly 

 black. The legs and antennas are finely dotted, the shafts of antennae 

 rather dark. 



The dehiscence shows a dorsal slit down the thorax, and to some 

 extent continuing laterally between the thorax and abdomen, on one side 

 little beyond the 1st abdominal segment, on the other reaching down the 

 wingmargin nearly to the 4th abdominal segment. The prothoracic piece
