2l8 THE entomologist's record. 



The larvte of one [L] of these broods were examined, and these 

 were nearly all of the typical T. cre^mscnlaria form, with the top of 

 the A-mark open at the top. 



The moths of these two broods commenced to emerge on August 8th, 

 and continued to do so during the whole of this month, and through 

 September into October ; the latest emergence, up to the end of 

 December, 1897, being a $ on December 14th, from pupae kept indoors. 

 Twenty-three specimens (11 ^s and 12 J s) of one brood [L] have 

 emerged, and seven pupae are going over ; of the other brood [K] 10 

 specimens (five ^ s and five $ s) have emerged, and five pupae are going 

 over. All the moths vary considerably in shade, and a few are remark- 

 able, if not unique, in having the central and basal area of wings pale, 

 the markings being very faint, and the coloration being, so to speak, 

 condensed into the marginal band, which is very broad and dark. 

 This tendency is apparent in all the moths, to a greater or less extent, 

 but the effect is only remarkable in three, having a pale and faintly 

 marked central and basal area. Three out of the above 23 specimens 

 were crippled. 



Two attempts [G and H] were made with ^ s and $ s of the brood 

 marked " X Dr. R.," i.e., $ bistortata X $ delamerensis. Only 

 one batch of eggs was laid, and these were nearly all fertile ; unfortu- 

 nately most of the larvae died during my absence from home. I examined 

 the eight or ten larvae which fed up ; some followed the bistortata type, 

 but the greater number were of the crepuscularia form. Only two 

 moths have emerged (a ^ and $ ), and one pupa is going over. 

 Both the moths are very small, but all well marked, the ^ dark 

 and 5 light. 



Parents of different hybrid stocks. — $ of X Dr. R. ( (J bistortata 

 X $ delamerensis) x 3 of No. la (J bistortata y. $ crej>usc}daria) . 

 Only one attempt [F]. All the ova laid were fertile, but the larvae 

 unfortunately died during my absence. The ova were very small and 

 rather ovoid in shape ; length, -028 ; breadth, -013 of an inch. 



Reverse cross to the above. — $ of X No. la (<? bistortata x 

 $ crepuscularia) x ^ of X Dr. R (c? bistortata x $ delamerensis). 

 Only one attempt [I], nearly all the ova fertile. All the larvas, save 

 one or two, died during my absence, the only pupa is going over. 



^ X No. 1 ((? delamerensis x $ bistortata) x ? X Dr. E {S^ 

 bistortata x ? delamerensis). Two attempts [B and C], both females 

 laid ova, but I only kept one batch [C] myself. A proportion of these 

 ova were infertile ; the larvae resulting from the fertile eggs died while 

 I was away. The ova of one of these batches were examined — Shape, 

 nearly oval ; length, -025 ; breadth, -015 of an inch. 



<J X No. 1 ( (? delamerensis x J bistortata) x $ No. la or 

 No. 2a ((? bistortata x ? crepuscularia). Three attempts [P, 

 and A], three batches of eggs laid, two of these kept, one [0] did not 

 hatch, but nearly all the eggs of the remaining batch [A] were fertile. 

 Unfortunately, most of these larvae died during my absence ; the only 

 pupa is lying over. Eggs were rather ovoid in shape ; length, -025 ; 

 breadth, -015 of an inch. 



Crossing hybrids with parent stock. — g X No. 1 ( S delamerensis 

 X $ bistortata) x 5? of 2nd brood bistortata. Only one attempt. 

 A batch of eggs were laid, but only one or two were fertile, and the 

 larvae unfortunately died whilst I was away.
