74 LEPIDOPTERA. 



{Calymnia) trapezina ; and Mr. H. J. Turner possesses one in 

 which the fore wings are so broadened in shape that it bears 

 a curious resemblance to Nodua haja. 



On the wing in June, more northward in July, An 

 occasional but rare and very partial second generation in 

 August or September, or even reared in October. 



Larva. Head very small, less than the second segment 

 and retractile ; antennal papillao conspicuous ; body obese, 

 cylindrical, attenuated in front ; each segment full and 

 rounded ; skin transversely wrinkled and with a fold beneath 

 the spiracles ; the head and body are furnished with slender 

 whitish bristles. Head wainscot-brown with two parallel 

 dark-brown marks, one on each side of the median suture. 

 The colour of the body varies slightly. The more usual type 

 is ferruginous or olivaceous-brown delicately reticulated with 

 darker, the segmental divisions usually distinctly tinged 

 with rosy. The dark reticulations on the back form a series 

 of somewhat indistinct lozenge-shaped marks, one on each 

 segment from the fifth to the twelfth, their edges shading off 

 into the ground colour. Through the centre of this series of 

 lozenges runs the threadlike and indistinct dorsal line, which 

 is ochreous, finely bordered on each side with brown ; it is 

 almost obliterated in the centre of each segment by the dark 

 lozenge. On the twelfth segment the lozenge is reduced to a 

 triangle, which is usually more clearly defined than the marks 

 on the other segments ; its apex points forward. Subdorsal 

 line ochreous, visible from the second to the twelfth segment 

 but most distinct and broadest on the hinder segments ; 

 bordered on each side by a fine brown line, and surmounted 

 on each from the fifth to the twelfth segments by a con- 

 spicuous, velvety, dark, almost black spot of somewhat trian- 

 gular form, the apex of the triangle pointing forward ; that 

 on the fifth, however, is indistinct and almost linear ; the 

 others increase gradually in size, those on the eleventh and 

 twelfth segment being the largest ; on the posterior edge of
