OF WASHINGTON, VOLUME XIII, 1!H1 231 



Cocoon double, an open mesh of pale brown silk, within a similar, 

 larger outer envelope. The pair come together at the anterior end 

 where the adult emerges. 



Pupa pale with transverse black lines on the abdomen and black 

 lines on the veins of the wing-cases. 



FAMILY NOCTUID^E. 

 Erebus odora Linnaeus. 



Mr. Gugelmann has sent three stages of the larva, presum- 

 ably the last three. The small larva is pale yellow with 

 broad black transverse bands on the anterior thirds of the 

 segments; a continuous black shade below the subventral fold; 

 head, feet, and shields dull red. A long black subdorsal fila- 

 ment, or "horn" on joints 3 and 4, and a single dorsal one on 

 joint 12. 



The next stage is colored like the fully grown larva, though 

 the secondary hairs and granular markings are less conspic- 

 uous. The five black horns are present. 



Last stage. Head rounded, wider than high, flat across the mouth, 

 shining dark brown, covered with short coarse pale secondary hairs. 

 Body cylindrical, uniform, without a trace of the black "horns" of the 

 previous stages. Anterior thirds of the segments dorsally black, 

 middle thirds red-brown, posterior thirds yellowish, the coloration con- 

 sisting of dense, flat, secondary granules; these cover the sides, except 

 for large black spots at the middle of the abdominal clasps; thoracic 

 feet and their bases black, anal shield and leg shield red-brown. The 

 granules are crinkled, annular and subconfluent. Skin densely cov- 

 ered with short pale secondary hairs, evenly throughout all the 

 markings. 



This large and conspicuous larva has a structure resembling 

 that of the Ceratocampidee in its younger stages. It would 

 be interesting to get the first stage of this larva and observe 

 the relations of these filamentous horns to the primary 

 tubercles. 



FAMILY NOTODONTID^. 



Dicentria laciniosa Hy. Rd wards. 



Larva. Head high, tapering a little above, with a small vertical 

 notch, much higher than joint 2; shining, creamy white with black 

 spots at the tubercles; the black forms a patch at vertex, a bilobed 

 mark across the face, a band above the mouth and a ring-spot on the 

 side. Body cylindrical, the anal feet small and apparently not used. 

 General color ocher yellow; a short bright red prominence on joint 5,
