normal, hook.s brown in small complete crochets. Skin dull red, slightly tinged with 

 purple, greenish in incisions between segments pink on ventral surface. 



Pupa. — From empty pupal shell. Length 4.5 mm., slender, cylindrical, taper- 

 ing evenly to anal end, which is rounded, not pointed, and armed with two short 

 recurved hairs. Wings and antenncc extend down to posterior edge of fifth abdominal 

 segment. Labial palpi slender, tapering evenly to almost a point and half as long as 

 wings. Vertex of head rounded and smooth, eyes rounded, moderate, prominent. 

 Dehiscence accomplished by labial palpi, to which is attached labrum, clypeus, and 

 eye caps, separating from prothoracic feet covers, on one side the split extends down 

 to lower end of palpi. On dorsal line the split extends length of thorax. Pupa 

 remains in cocoon when moth emerges. 



The eggs are deposited in the summer, and young larvcC begin 

 mining in the preceding year's leaves, avoiding the tender and resin- 

 ous young leaves of the present year ; they are probably more than 

 half grown by fall and hibernate in this stage. In the very early 

 spring, late February and early March, on warm sunny days the larvae 

 can be seen travelling a few inches farther out the twig and starting a 

 fresh mine, this time in the growth that was new their first year. 



The interior of the peculiar close-jointed leaves, is completely 

 excavated, causing the empty leaves to turn yellow, and these small 

 patches are easily seen as contrasted with the natural dark green foli- 

 age (Plate IX, Fig. 21, enlarged). When ready to pupate the 

 larva lines one of the leaflets with white silk, making a roomy little 

 cell and begins pupating latter part of May, first moths emerged June 

 7, and continue during June. 



A few hymenopterous parasites were bred, issuing about the same 

 time as the moths, which Dr. Ashmead describes as new in this num- 

 ber of the Journal (p. 144) under the name of Protapantelcs recur- 

 varicc Ashm. 



Recurvaria piceaella, sp. nov. Plate IX, Figs. 10 and 19. 



Markings same as thujaella, except the light shades have an ochreous tone 

 rather than fuscous as in thitjnella. The average size of piceaella is about I mm. 

 greater than of piceaella. Otherwise, the two species are very difficult to separate 

 in the imago state, and my only justification in making two species is in the consider- 

 able ditference in the larva.> and their food plants. Alar expanse, 9.5 to 1 1. 5 mm.

 brown, prothoracic shield same but lighter. Skin red on dorsal, lateral and ventral
