ORTHOT.ENIA, Curtis. 

 The palpi are porrected horizontally, thickly squamosa, but with the terminal joint exposed and slender ; 

 the antennae are slender, and slightly pubescent beneath, in the males ; the head is coarsely squamose ; the 

 thorax not tnfted ; the fore wings rather elongate, triangular, with the apical margin rather rounded ; the disc 

 generally of red or brown colours, with slender silvery markings forming irregular spots and fascise. The 

 caterpillars are naked and sixteen-footed. 



Species 1 — Orthot^nia Tdrionella'' — (Plate XCIX., Figs. 1, 2) — Measures from 6 to 11 lines in 

 expanse ; fore wings dark orange-coloured, with five transverse, irregular, silvery, anastomosing streaks ; the 

 second and fourth forked next the costal margin, the third forming a ring in the centre ; and the fifth 

 abbreviated, and subapical fringe with a blackish line near the base : hind wings dusky. The caterpillar is 

 reddish-brown, with a black head, and feeds on the shoots of the Scotch fir. Taken in June, in Kent, Norfolk, 

 and Yorkshire ; but rare. See the history of this species in " KoUar's Treatise on Injurious Insects," translated 

 by Mrs. Loudon, and published by the publisher of this work.

Species 2.— Orthot^nia geminana^' — (Plate XCIX., Figs. 3—6) — Measures from 6 to 8 lines in 

 expanse ; fore wings of a cinnamon red colour, (darker than in the preceding species,) with several duplicated, 

 clear, silvery striga and connecting dashes of the same ; the costa slightly dotted with white : hind wings

 some of the other species of the genus, its caterpillar feeds within the young shoots of the fir, occasionally doing 

 considerable mischief.
