76 BRITISH ORTHOPTERA. 



OOTHECA (fig. lo, no. 1).- -Bright sienna-brown, 

 having somewhat the appearance of a small leguminous 

 seed. On 5 July 1902 several E. lapponicus were 

 taken at Boldermere, near Wisley in Surrey in one 

 instance a pair in copula. The female was rather 

 smaller, much lighter, rounder in outline, and possess- 

 ing shorter elytra, than the male. These were taken 

 home alive. On 19 July the female was protruding a 

 pnle yellowish-brown ootheca at any rate on that day 

 it was first noticed, and she had been looked at most 

 days previously. So the ootheca is not apparent till 

 some days after copulation. The male died a day or 

 so after capture ; the female was fed on strawberry 

 and then on banana. The ootheca was dropped on 

 24 July, and never became darker than palish sienna- 

 brown. It was smaller than usually given in figures, 

 but that may have been due to the unnatural conditions 

 under which the female was living when it was being 

 formed. 



NYMPH.- -Burr* says that the nymphs are entirely 

 black, except the sides of the pronotum which are 

 pale. A very small one I have from the New Forest 

 is nearly uniform sienna-brown. 



VARIATION.- -Size is fairly constant; but depth of 

 colouring varies considerably, especially in the female. 

 A form with generally paler colour and reddish 

 pronotum makes a close approach in appearance to 

 E. perspicillaris Herbst. On 6 May 1908 Shelf ord 

 exhibited at the Entom. Society of London a species 

 very near to E. lapponicus, preserved in amber. 



DATE.- -This cockroach may be found from May to 

 September at least. How the winter is passed does 

 not seem to have been observed. 



HABITS.- -E. lapponicus may be found under moss 

 and dry leaves, amongst the undergrowth in woods, 

 and, generally, on vegetation close to the ground, 

 though it may sometimes be obtained from bushes or
