NEW SPECIES OF NOCTUIDH FROM FORMOSA. 219 
do I recollect or know how far the habitat of A. strigosa was or 
is included in the now preserved portion of the Fen. A. strigosa 
feeds on hawthorn, and why it should be so localised is not very 
obvious. Various reasons may be suggested, climatic and others. 
There is one somewhat important one, as to which I feel tolerably 
certain. A. strigosa pupates in a cocoon which it forms by 
burrowing into rotten wood, and consequently it cannot thrive 
unless the trees on which it lives are old and possess some dead 
portions that have some fairly rotten wood. No doubt larve on 
other hawthorn trees will find places in which to pupate, but 
such places will be unsuitable, and will result in the greater 
number of individuals who do so perishing in the winter. Not 
impossibly stumps of cut reeds may afford as good substitutes 
as any. 
The point, however, on which I desire for the moment to 
insist, is that old hawthorn trees should be jealously guarded, 
and that sufficient younger trees should be spared in order that 
in due time they may replace the older ones as these perish, and 
that none of the old ones and not all the younger shall be 
included in the sweeping condemnation of ‘‘ low shrubby trees.”

Trachea conjuncta, sp. n. 
3. Head and thorax whitish, the latter marked with dark brown 
on edges of collar and patagia; antenne bipectinate except at tip. 
Fore wings whitish, tinged and clouded with ochreous brown; subbasal 
line black, double, wavy, not clearly defined ; antemedial line black, 
double, sinuous; postmedial line black, double, strongly curved from 
costa to middle, thence sinuous to dorsum ; a broad oblique blackish 
band from costa to about middle of a black bar connecting antemedial 
and postmedial lines, and a narrow oblique blackish band from the 
connecting bar to dorsum; orbicular and reniform stigmata whitish, 
finely outlined in black and enclosing brownish marks; a blackish 
quadrate mark (extending to costa) between the stigmata; three 
blackish marks on terminal third of the wing—one at costal end of 
postmedial line, one (the largest) below middle of postmedial, one 
below apex ; fringes chequered with black. Hind wings white with 
blackish discoidal dot and two dusky transverse lines beyond; fringes 
grey brown. Under side whitish; fore wings suffused with dusky 
except on margins, the blackish postmedial line is preceded by a 
blackish cloud on costal area; hind wings have a black discoidal 
lunule and blackish transverse line as above.
