190 THE entomologist's recorb. 



above the vertical rows increase in niunber liy division and intercala- 

 tion, just as the ribs do in many Noctuid eggs. — T. A. Chapaian, M.D., 

 F.Z.H. [We observe since the above was in type that Helhns noticed 

 the inadequacy of his first description of the egg of this species, and 

 followed it up by a more complete one, K.M.M., vol. x., p. 139.] 



The following eggs were all described when holiday keeping, using 

 a two-thirds, as a hand, lens, and must be taken for what they are 

 worth : — 



Antltrocem jiemnhoii. — Of a pale straw-colour when freshly laid ; 

 oval in outline ; depressed over almost the whole of the upper surface ; 

 the surface wrinkled longitudinally, only slightly shiny, and apparently 

 finely pitted ; uniform in colour (not with one pole transparent, so far 

 as could be observed). Length : breadth : height, about as 4 : 3 : 2. 

 One female laid about 154 eggs, with many loose scales scattered over 

 the egg-masses, which are deposited in the most regular manner in rows, 

 with the long sides touching each other, and without any visible space 

 between the successive rows. [Described from eggs laid by a red- 

 belted, six-spotted female, captured at Aix-les-Bains, July 27th, 1898.] 



Aridalia nifata. — Pearly- white in colour, with a very faint 

 pinkish tinge when first laid (July 27th) ; a moderately long oval in 

 outline, with six distinct longitudinal ribs on upper surface ; some- 

 what flattened but no distinct depression on upper surface. By August 

 3rd they were of a delicate salmon colour, uniformly tinted through- 

 out, with the four longitudinal ribs on npper surface and the two on 

 the edges very conspicuous ; there is distinctly no depression, nor is 

 the colour disposed in spots. No trace of embryo is discernible. 

 [Described from eggs laid by a female captured at Aix-les-Bains, 

 July 27th, 1898.] 



Si/nt(i))iis jJu'iica. — A batch of from 50 to 60 eggs were laid in a box 

 in which the ? was confined. They are of typical Arctiid shape, 

 about three-quarters or more of a sphere, the apex almost smooth ; 

 the remainder of the surface very finely pitted. The surface reminds 

 one of the texture of fine silk. The newly laid egg is of a very pale 

 buff' colour. No trace of micropyle discernible with the power at 

 disposal. [Described under a two-thirds, used as a hand, lens, August 

 14th, 1898, from eggs laid bv a ^ captured the same day at Pre Ht. 

 Didier.]— J. W. TuTT. 



Egg-laying of Drymonia chaonia. — A male and female Ih-ijiiKinia 

 chaonia emerged together on April 17th (the ? parent having been 

 taken in trap May 14th, 1898) in the afternoon between 2 and G p.m. 

 They were placed together in breeding cage and began to get restless 

 and fly about cage, and about 7.30 p.m. I covered the cage to keep out 

 the light. They were found in coji. at 9.30 p.m., and by the 18th at 

 9.0 a.m. they had separated and the female had deposited 25 ova 

 scattered about the cage. I then killed the c? and placed the $ in 

 a chip box. No more ova had been deposited by 1 p.m., but by 5 p.m. 

 many had been laid, and by the morning of the 19th, 114. The 

 female was then removed to another chip box, but by 5 p.m. she had 

 laid no more. Shortly afterwards she did, and by the morning of the 

 20th had laid 41 more, making a total of 170. They hatched on 

 April 28th-29th, in a room without a fire. — E. F. C. Studd, M.A., 

 Oxton, Exeter. Mai/ it/,, 1899.
