TRIFID.E. 361 



Body legs and leg-tufts pale cliocolate -red ; tibia) faintly 

 barred with paler. 



Hardly variable, except that the cloudy chocolate markings 

 are sometimes very faint, the fore wings consequently almost 

 unicolorous yellow-brown. In North Lancashire specimens 

 are found in which the fulvous tints are replaced by purplish- 

 brown and drab. 



On the wing in June and July. 



Larva not described. It is said to be similar to that of 

 X. lithoxylca but of a redder colour. 



Pupa said to resemble that of X. lithoxylca, but to have a 

 stouter cremaster with four bristles. 



The moth is rarely seen in the daytime. It doubtless hides 

 among grass and herbage or under dead leaves on the ground. 

 It flies at rather late dusk, and comes readily to sugar and 

 to light. Apparently, it is principally attached to chalk and 

 limestone districts, especially on the coast, though it is com- 

 mon enough in beech woods on chalk hills inland. It formerly 

 occurred afc Hampstead, North London, but has doubtless 

 been expelled by the prevalence of buildings. Abundant on 

 the coast of Kent and also in the beech woods of Oxford- 

 shire, Berkshire, Wiltshire and Bucks ; common also on the 

 Dorset coast, less so inland ; rare in Devon, local in Somerset 

 and Gloucestershire ; also found, though not abundantly, in 

 Huntingdonshire, Cambridgeshire, Suffolk, and Norfolk, and 

 rarely in Lincolnshire, Yorkshire, Worcestershire and Lan- 

 cashire, but apparently not noticed in the Midlands nor 

 further north than Yorkshire ; and I have no record in Wales. 

 Much more generally distributed in Ireland, formerly com- 

 mon in the outskirts of Dublin ; also recorded from Galway, 

 Sligo, Westmeath, King's County, Tipperary, Wicklow, and 

 Tyrone, and in some of these districts abundant. Abroad 

 its range seems to be restricted to France, Holland, Germany, 

 and Central and Western Russia.
