Flecken, <lie lici dein einen Kzemplur kleiner inui 

 weit von einander getrennt sind, bei dem anderen 

 dagegen eine blos durch die Adern unterbrochene 

 Binde bilden. Die beiden imterston Flocke ^zwischen 

 deu Medianästen sind bei diesem Stücke sehr gross, 

 sechseckig, nach Innen und Aussen zugespitzt, der 

 darüber folgende (wie bei der Stamm:irt) Iftnger als 

 die zuerst genannten, diese beiderseits überragend, 

 nach Innen gerade abgeschnitten, nach Aussen spitz

 (bei dem anderen Exemplar auch die beiden Flecke 

 zwischen den Medianiisten ) sehr klein, unregelmässig. 

 Alle Flecke sind scharf begrenzt, bei beiden Stücken 

 nicht röthlich gelb, wie bei der Stammarf, sondern 

 Mass ueissgelb, in auffallendem Gegensatze zur 

 Färbung der Binde auf den Vorderflügeln, wie dies 

 in solchem Grade bei keiner anderen der näher ver- 

 wandten Krebia- Arten der Fall ist. Im Uebrigen 

 sind die Hiuterflügel ganz einfarbig, von Basaltieckeii, 

 wie solche die normalen Manto p p aufweisen, ist 

 nicht die geringste Spur vorbanden.

Emergence of sexes in Bombyx quercus. 



B\ l'ranh Brnmihiw. 



The following notes on the emergence of sexes 

 in Bombi/x quercus were taken on specimens of tlie 

 species which I bred, this year, from pup;c obtaiped 

 from Caussols and Nico lAlpes-Maritimes, France), 

 during the summer and autumn of 189.3. The 

 greater part of the lavvn' were, liowever, collected 

 in the former place, where they were common on 

 a kind of broom (Genistet) — probably G.-cinerea, 

 which is said to occur here. They were fed up 

 during the ensuing winter on the ordinary garden 

 rose, on which they throve well, and the first Cater- 

 pillar pupated about the 2.4rd of January l.'^ft4. 

 Probably those larvce of Bombi/x quercus found at 

 Caussols, would have chosen rose or any otlier 

 pabulum of a similar succuleuce, had this been 

 obtainable in this bleak mountain place, where 

 hardly a free was to be seen — in preference to 

 Genista. which last must contain only a limited 

 amount of nourishment, belüg, in great part, cora- 

 posed of fibres, Keferring to my diary, I sec that 

 I obtained in all tbirteen chrysalids from my cater- 



pillars. Thf first moth to omerge was a female, 

 which canie out on the 9th of June (1S94), at 

 which date I had eleven pupa\ and two larva' were 

 still feeding up. This was followed by a male, 

 well-expanded, on the 2öth inst. On the 2!ttb ulto. 

 a crippled male emcrged. The .SOth. inst, saw a 

 delormed male out, which failed to properly expand 

 its wings. 



.Tuly 2nd witnessed the birth of another example 

 (probably a male), which escaped, doubtless through 

 the opeu window. This last, came out of the lirst- 

 formed pupa (of about 2.3rd of .Tanuary last, and 

 which has been already referred to), showing that 

 those chrysalids, which are the first to be made, 

 are not neccessarily the first to yield imagines. 



A female than emerged on the iMd inst., and 

 on the 19th ulto. — after an interval of sixteen 

 days, — another female came forth. On the ."11 st 

 inst., suspecting something to be wrong, I opened 

 a pupa which seemed to have been an unusually 

 long time in the chrysalis State, and found it to 

 have been " ichneuraoned", that is to say, it was 

 infested by tiie grubs of a parasite ichneumon-fly. 

 On August cth, a female saw the light, and on the 

 ■2'.\\\\ inst, another female came out in my cage, 

 — after an interval of exactly sever.teen days. This 

 last, unfortunately, had its left-haud hind-wing 

 crumpled. Whether because it was the last of its' 

 tribe, or for v.'hat other reason, I cannot say, but 

 this insect laid a huiidred and sixty-two eggs! 

 Needless to say, they were infertile. I had hoped 

 to get a pairing from one couple, at any rate, of 

 all the niales and females which had emerged in 

 my puparinm, but this, 1 regret to say, could not 

 be effected, as the interval between the various, 

 hatchiugs was too prolonged.
