4. Resinella, Linn. Alls anticis brunneis obscuris, strigis subar- 

 genteis; costa lineolis geminatis ad marginem dorsalem pro- 

 ductis ; apice puncto rotundo ; posticis aureo -brunneis. <$ Exp. al.

Head dull umber. Face above dull umber, below pale ochreous. 

 Eyes black. Palpi as long as the head ; above umbreous, beneath 

 dull ochreous. Antenna? fuscous. Thorax umbreous, mixed with 

 grey scales. Patagia of the same colour as the thorax, but with 

 more grey scales. Anterior wings dull, rich umber, with silvery- 

 lustred streaks and markings ; at the base are several undulated 

 streaks proceeding from the costa to the dorsal margin ; on the 

 costa beyond these, but before the middle, are two geminations, 

 which are produced and dilated irregularly to the dorsal margin ; 

 beyond the middle are four other geminations ; these unite two and 

 two, and afterwards are produced to the opposite margin. The apical 

 spot distinct. Apical scales umbreous, interrupted by silvery patches. 

 Cilia glossy, iron-grey. Posterior wings with a subdued gloss, golden 

 umbreous brown. Marginal scales golden umbreous brown. Cilia

A Scotch species ; allied to R. Pinivorana, which it much re- 

 sembles, but has the anterior wings broader, and the markings 

 vmbreous instead of dusky ochreous brown ; also variable in size 

 and colour. 



The imago appears in June among Fir-trees, in Perthshire, 

 and has been bred freely by Mr. Bouchard. 



The larva feeds within a hollow resinous exudation from the 

 branches of Pine-trees, occasioned by the wound in the bark 

 made by the young larva feeding therein.
