nymph was taken in the Xew Forest, with the circular 

 whitish patch on the pronotum : this had immature

 freely. This points to the fact that, like its commoner

congener, it passes the winter as an imago, and that 

 the eggs are laid in the spring- -probably about May.

 bottle. On examining them afterwards all were found 

 to be adult- -16 females and 7 males. (The difference

 males are very small and inconspicuous.)

 Forest (apparently a long-disused marl-pit of great 

 extent) T. snlulatus occurs rather freely in wet places, 

 where a great deal of moss and similar vegetation is
