on the dorsum of case are about 0.32 mm. in diameter and are 

 arranged as shown in the figure. Those forming the row of six on 

 the abdomen between the submarginal row of papillae and the 

 double median row are about 0.16 mm. from the outer pores of the 

 double median row. A channel extends from the vasiform orifice 

 to the margin of the case. On either side of the channel is a thickened 

 wrinkled lobe-like ridge between the orifice and the margin. 



We have specimens taken on ArctostapJiylos species, near Camp 

 Rincon, San Gabriel Mountains, California, July 4, 1911, by P. H. 

 Timberlake. These specimens show some differences from the 

 para types mentioned above. The most noticeable difference is in the 

 submarginal papillae, which are elongate in these specimens and 

 measure about 0.048 mm. The pores also are somewhat larger.

Two collections of this species are in the Bureau of Entomology. 

 Q. No. 1980 was taken on Liihraea caustica, at Santiago, Chile, by 

 Manuel J. Rivera, October 25, 1905, and Q. No. 8821 was taken on 

 Quillaja sapororia and sent from the same city by Carlos E. Porter 

 in March, 1905. 



Pupa case. — Size 1.44 mm. by 1.12 mm., subelliptical, broadly 

 rounded at the ends. The margin of the dorsal disk shows a very 

 irregular, somewhat thickened Une. The median dorsal abdominal 

 ridge is armed on each segment with three to five irregular pore-like 

 areas, which are usually crowded together. These are much smaller 

 than the corresponding ones in iridescens. The transverse cephalic 

 row of pore-hke areas upon the thorax consists of sometimes as 

 many as 18. On the submarginal area of the abdomen some dis- 

 tance mesad and often occupying a part of the margin of the dorsal 

 disk there is an irregular row of minute pore-like areas. This row 

 is most often of three pores in thickness, but often is only a single 

 irregular row. Sometimes it is scarcely visible at all. The pores 

 forming this row are much smaller than those present on the similar 

 region of iridescens. The papillae-like structures forming a row 

 about the case just within the margin are in this species short, ex- 

 tending mesad only about 0.016 mm., but the suture-like markings 

 between them extend considerably farther mesad. In iridescens, on 

 the other hand, the sutures between the papillae extend scarcely 

 mesad of the papillae themselves. Comb of the thoracic tracheal 

 fold very similar to that of iridescens, consisting of three teeth. 

 Vasiform orifice typical for the genus, about 0.112 mm. by 0.096 mm. 

 in size and about 0.128 mm. from caudal margin. There is a channel
