with one of the forks broken off; in walking, its 
humps lose much of their prominence, and then it 
looks much lke other stout geometers. 
The pupa is enclosed in a slight cocoon, placed just 
on the surface of the soil, and formed by drawing 
together moss, etc.; 16 1s about three-quarters of an 
inch long, cylindrical, the thorax and upper part of the 
abdomen stoutish, the lower part tapering off rapidly ; 
the wing-cases granulated and dull, the abdomen 
elossy.; the whole pupa skin sparsely set with fine 
bristles; the anal spike triangular, flattened, and ending 
in a long fine spine, barely bifurcated at the tip; 
colour a very dark brown, with the abdominal rings 
reddish. (John Hellins, May 30th, 1874; H.M.M.,

Plate CXII, fig. 4. 
Another geometer which came commonly to sugar, 
but not so abundantly as did Tephrosia extersaria, 
during the expedition of Mr. W. H. Tugwell and 
myself to Abbott’s Wood, Sussex, in June, 1892 (see 
Hnt. Mo. Mag., March, 1895, p. 65), was Boarmia

Hees deposited by some of the specimens taken ~ 
were bright green, and small for so large a moth. 
The young larve hatched on June 24th, and fed 
well on oak, birch, and sallow, some of them being 
almost full grown by August 3rd, when I described 
them as follows : 
Length about an inch and three quarters, and

the second segment, notched, but not deeply so, on 
the crown, the lobes rounded at the sides, but flattened
