the larva of R. Buoliana which only distorts the shoots; it 

 must be sought for early in April. 



8. occultana, Doug. Alls anticis nitidis griseis ; basi macula rhom- 

 bea ; fascia media apiceque nigris subreticulatis ; posticis fuscis. 

 c? Exp. al. 8-10 lin. 



Head smoky black, the scales tipped with grey. Face above co- 

 loured like the head, whitish below. Eyes black. Palpi above and 

 at the sides dark grey, beneath the apex dark grey, the base pale drab. 

 Antennas deep fuscous. Thorax and patagia smoky black, the tips of 

 the scales grey. Anterior wings glossy, pale grey ; at the base is a 

 rhomboid patch, extending one-fourth along the costa and one-third 

 along the dorsal margin, of blackish colour, darkest at its posterior 

 edge, and thickly irrorated with grey scales ; at the middle of the 

 costa commences a slightly-curved fascia, somewhat angulated and 

 of nearly equal width, shortly after its commencement, where it is 

 narrowest ; its colour is similar to the basal patch at its costal half, 

 the dorsal portion being mixed with obscure ochreous brown. The 

 apical region reticulated with black, and, with the apical margin, 

 streaked with ochreous brown. The costa is blackish, alternated 

 throughout with geminated grey streaks, which are most distinct 

 towards the apex. Apical spot distinct ; the dorsal margin thickly 

 maculated with black, and the paler portions of the wing streaked 

 with dusky. Apical scales black, tipped with grey, with white 

 bases, at the apex and before the anal angle pale grey, the re- 

 mainder, with the bases, obscure ochreous brown. Cilia glossy, 

 dull fuscous, with whitish tips. Posterior wings dull, dark fuscous, 

 deepest at the apex. Marginal scales darker fuscous. Cilia pale 

 fuscous grey, both with the bases, straw-colour. Abdomen and the 

 caudal tuft shining, smoky black. $ Exp. al. 9-11 lin. In colour 

 and markings like the $ , but without the obscure ochreous colour 

 of the central fascia, apical streaks, and scales, which are in this sex 

 black. 



A common insect among Larch- and Fir-trees, and subject to 

 great variation in the intensity of its colouring, the northern 

 specimens being the most distinctly marked. 



The imago appears in June and July throughout the Metro- 

 politan district, near Brighton and other places in the south of 

 England. It occurs also in the vicinity of Edinburgh. 



Genus X. PAMPLUSIA, GUENEE. 



Palpi longer than the head, ascending, diverging ; basal joint 

 curved, short, nearly isometric ; apical slender, obovate, nearly twice 

 the length of the basal, directed horizontally; middle ascending,
