ON SOME RACES OV LASlOCAJVlPA QlJERCtlS. 34l 



moult occurred June 8th, 1899. This is the only entry I have about 

 them. 



The remaining two families are particularly curious in their females. 

 The 3" parent of both was the same individual, but unfortunately 

 there is doubt as to its pedigree. It was reputed to be a 9 x 7 (the 

 batch which suffered most in the upset), but in markings it is a pure L. 

 var. aicida with but the slightest powdering of darker on the border of 

 the hindwing. I would not hesitate to put it down as pure L. var. 

 siciila except that the hybrids from it and the Paris qucrn'oi $ are con- 

 siderably less .s/r»/rt-like than the 9 x 10 lot (3617) already described. 

 To proceed to these two families in detail : — 



(9)L.hybr. (? [sicKlax{iiuTi(li(nialisxvibi(nii) or {siciila)] x ? [sieida 

 X {iiicn'dionalis X vihnnii)] , [= <? (9 X 7) X 2 (9 X 7)] . — This was the first 

 pairing of the male just mentioned. The pedigree of the ? is almost 

 certainly correct. It is a large dark specimen agreeing with Mr. Bacot's 

 9x7, and has a blending of the characters without a conspicuously L. 

 var. siinda border. The ova (lot 3G11) were deposited about July 30th, 

 1898, only a few of them hatched (on August 22nd, 1898). Two other 

 pairings of these hybrids (in which the ^ s were both of the vibunii-like 

 type already referred to) produced, respectively, 26 and 50 sterile ova. The 

 1st moult of the above (lot 3614) took place September 9th, 1898. Two 

 females emei-ged in May 1899, and another one is recorded in Sep- 

 tember 1900, which I cannot trace. Six pupae lie over, possibly alive. 

 The young larvie resembled lot 3646 [(9 X 7) X 10] and 3640 [(9 X 2) x 

 (6 X 6)] , but with a few scattered black hairs. After the 1st moult they 

 were like those of the foregoing two batches, and had no, or hardly any, 

 black hairs. The ? moths are small but very pretty. The slightly 

 scalloped fringe of the hindwing (slightly noticeable in L. sicida) is 

 marked with grey at the tips of the nervures, which on the forewing 

 darken when halfway across the band. This colouring is slight but 

 enough to impart a neat look to the insect. The other markings are 

 like L. var. sicida. The colour dull sinda. 



(10) L. hybr. [sicida x {incridio)iaUs x ribi(rni) or (sicida)] x ijiwrciis 

 (Paris) [= (9 X 7) X 10] . — This is the second pairing of the same male 

 and, as pointed out, if it were pure L. sicida would be the same in 

 descent as lot 3647 (9x10). The female parent fairly large, pale; 

 dark lines marked inside band on forewings and around the dot. 

 Bands obsolescent, whole margin pale in hindwing. The ova (lot 

 3646) laid about August 2nd, 1898, all hatched August 26th, 1898, and 

 after. The moths emerged 25 c? s and 9 $ s, on March 1st, 1899, and 

 after, and in the next year 3 ? s, August 19th, 1900, and after. The same 

 curious phenomenon with regard to dates as in some of the other batches 

 was observed. The following is the description of the various stages : — 

 Ova very large, mottled red-brown. Larva before 1st moult: Ashy-white, 

 very distinct dorsal line, continuous or only slightly interrupted by the 

 segmental divisions ; sides blue-black, with orange costal or sub- 

 dorsal spots on black ones, the latter most marked on the 4th segment. 

 Possibly these markings, when observed with a lens appear a little 

 more contrasted with the ground colour than they do in lot 3610 [(9 X 2) 

 x(6x6)]. Long hairs all white. After the 1st moult (l);\ginning 

 September 9th, 1898), rusty-orange diamonds appear on the back; 

 the sides black with the pattern as before ; head pale blue, face 

 whitish ; first two or three segments large, with long silky-white hairs,
