four years from eggs deposited by captured females. I have 

 invariably found them hybernate in that state, and commence 

 hatching the last week in February." — R. S.] 



Peridea trepida in Essex. — On May 16th I found two fine 

 specimens, male and female, of P. trepida, on an oak trunk, near 

 Brentwood. The female has laid over 300 eggs. Is it usual for 

 members of the family Notodontidae to lay so large a number of 

 eggs ? — R. G. WiLLiMENT ; Hon. Sec, Field Club, Brentwood. 



Tephrosia crepuscularia. — The following notes concerning 

 Teplirosia crepuscularia in this district during the present season 

 may be of interest, altliough so much has been previously written 

 in the 'Entomologist' on the subject. From the backward 

 spring I did not observe any specimens until March 20th. I 

 have usually seen them early in the month. On April 12th, 

 amongst many specimens observed, I saw three, with the ground 

 colour white. One of these, a female, apparently just emerged, 

 I brought home, and placed with a brown-coloured male. I 

 believe tliey copulated ; however, tliis female deposited eggs, 

 which have since proved fertile. The eggs were found laid in 

 crevices of the breeding-box on April 25th; and another 

 specimen, obtained by a friend and placed under a bell-glass, 

 laid eggs underneath a piece of bark. It appears evidently from 

 this that in the natural state the eggs are concealed under the 

 bark of trees, as far as possible. The young larvse commenced 

 to hatch out on May 13th. I tried Scotch fir and larch, pear, 

 and plum for their food, neither of which appeared to satisfy 

 them. I then placed blackthorn, on which they immediately 

 commenced to feed readily, although they appeared inclined 

 somewhat to the larch. Here I find the imago chiefly in fir 

 plantations, and have unearthed the pupse at the foot of larch 

 trees, so that it appears somewhat strange the larvse not taking 

 readily to the larch. When hatched the young larvge were all of 

 deep black colour, with white divisions of the segments. The 

 first to appear, however, have already changed in colour, being 

 now brown, with white divisions of the segments. They appear 

 to be feeding up rapidly. — T. B. Jefferys ; Clevedon, May 19. 



Eupcecilia udana. — Is this insect really double-brooded ? I 

 am induced to ask this question from having been repeatedly told 

 by entomologists that there are two broods in the year, the
