occiput with two elongated tubercles ; first three segments 

 blackish-brown, slightly tinged with reddish, and with small 

 tubercles above, from which arise long fuscous hairs ; three fol- 

 lowing segments black, polished, and each above furnished with 

 a broad hump, surmounted with elongated, setigerous, black 

 tubercles ; seventh, eighth and ninth segments polished, white, 

 veined with black above, and with minute tubercles, each of 

 which furnishes a short white hair ; tenth segment black, pol- 

 ished or shining, veined with white, and tuberculated ; penulti- 

 mate blackish, furnished above with a large, flat-topped hump, 

 studded with piliferous black tubercles ; tail black, veined with 

 white, and tuberculated ; an obsolete, white, dorsal line ; pec- 

 toral feet reddish-brown, varied with black ; abdominal or 

 spurious feet very long, anteriorly blackish, laterally white, 

 with black lines ; body beneath blackish, varied with reddish. 

 Length twelve lines ; breadth one and one-half or two lines. 

 Food, the leaves of winter-berry {Prinos verticellatus). Time, 

 last of August. Transformation of larva into pupa, September, 

 above ground in dry wood. The larva gnaws a cavity in the 

 interior of a round dry stick, and closes the entrance with a 

 firm web. The perfect insects were disclosed in June, after 

 remaining in the pupa state almost two years. Pupa naked, 

 subcylindrical ; terminal segments blunt, without a spine. The 

 manners of the larva are somewhat remarkable. In repose 

 the anterior portion of the body is elevated, resting only on 

 the four hindermost pair of pro -legs ; and when the larva is 

 at any time disturbed, it moves the elevated part sideways very 

 rapidly." Your figure represents a female specimen. Thon, 

 in his Archives, has figured an insect almost identical with 

 71(j, which he placed in the genus Notodonta.
