NOTES AND OBSERVATIONS. 61 



than one specimen. He says the egg (Entora. xxvi. p. 7) '• has about 

 fourteen longitudinal ridges, which do not, however, meet at the top, but 

 terminate at the circumference of a small circle, the intervening de- 

 pressions between the ridges being most delicately reticulated transversely." 

 I closely examined a number of eggs — about eighteen — with both a high 

 and low power, and found the longitudinal keels to vary in number from 

 nineteen to twenty-two, in no case less than nineteen, the average number 

 being twenty-one instead of " fourteen " ; the spaces between the keels have 

 a Battened surface, and are most delicately but irregularly ribbed transversely 

 by about forty-six in number, and not " reticiolated.'" Mr. Williams states 

 "the newly-hatched larva is a greyish green," whereas all the number I 

 examined had the ground colour ochreous-yellow, the dull olive colouring 

 being caused by the minute black warts being so densely sprinkled over the 

 surface; the "minute bristles," alluded to by Mr. Williams, are not 

 bristles, but short club-shaped tubercles. After the first moult the head is 

 olive-green mottled with dark olive-brown, which he describes as having a 

 " light brown appearance, being studded with minute blackish spots," and 

 also " extending down the middle of the back is a furrow.'" Such I entirely 

 failed to detect, as no furrow exists, but simply that part of the surface is 

 devoid of hairs. After the second moult the body is deep clover-green and 

 the head pale ochreous-green, whilst Mr. Williams says "both head 

 and body uniform in colour." For further details relating to the above 

 stages, see Entom. xxv. pp. 271-4. — F. W. Fro hawk ; Balhara, January,

Lepidoptera at Light. — I see, under the above heading (Entora. 15), 

 that Mr. G. B. Routledge corroborates Mr. Arkle's experience in males and 

 females at light. I know of only one exception to the rule, viz., Bombyx 

 rubi. The females only of this species come to my trap, although there 

 are hundreds of males flying about the park from 4 p.m. till dusk. I took 

 a female P. loopidi at light on November 24th, 1892; but though I took 

 over a hundred Anchocelis lunosa by same means, not one was a female. —

Male v. Female Leptdoptera at Light. — The following notes on 

 males v. females at light concern such species as I have frequently met with 

 in the Bristol neighbourhood : — Dasychira pudibunda, males abundant every 

 season ; proportion to females about 20 — 1. Ainphidasys prodromaria, a 

 few males most years ; never a female. Selenia illustraria, proportion of 

 males to females, 10 — 1. Odontoptera bldeiitata, males very abundant every 

 May ; as many as six on a lamp, sometimes ; not one female taken at light. 

 Crocallis elinguaria, males also abundant at light ; no female recorded. 

 Ennomos tiliaria, common ; males to females about 30 — 1. Tephrosia 

 crepuscidaria, common ; males to females about 12 — 1. Notodonta 

 diciceoides, a few males at lamps most years ; a female never. The only 

 specimen of Bombyx rubi I have ever taken at light was a female ; this 

 perhaps was to be expected, as, contrary to the males, the females fly after 

 dusk, I having once taken one fluttering over the herbage at about 9 p.m.

 The following list may be of interest as a contribution to the statistics of
