margin slightly curved caudad. The caudal and lateral margins 

 inside are armed with a number of short, acute fimbriae; the lower 

 inner lining of the orifice is coarsely reticulate, giving it an irregular 

 serrate appearance. The operculum is semicircular or slightly cres- 

 cent shaped, and about half fills the orifice, obscuring the lingula, 

 which is setose and armed with two fme bristles (fig. 3). 



Represented by one pupa case in balsam in the Maskell collection. 



Habitat. — New Zealand, on Drimys axillaris, on the leaves of which 

 it produces a characteristic pitting.

Paratypes of this species are in the bureau collection and consist of 

 eggs, larvae, and pupa cases. We have also for study specimens of 

 pupa cases and adults taken by Mr. G. E. Bodkin, on leaves of jasmine, 

 Georgetown, Demerara, British Guiana, February, 1912. 



Egg. — Size about 0.178 mm. long by about 0.096 mm. wide a short 

 distance from the unstalked end, narrower at the stalked end; color 

 yellowish. In hatchmg the egg sphts doAvnward for 0.09 mm. and 

 spreads open considerably; surface without sculpturing; stalk at- 

 tached near the middle. 



Larva, first instar (pi. 67, fig. 11). — Size 0.24 by 0.16 mm.; regularly 

 elliptical; color light yellow, with dark brown eyespots. There are 

 on the margin of the specimens at hand 14 pairs of hairs, the po- 

 sition of which is best shown in the figure. It will be noted that 

 there are a number of marginal papillae on which no hairs are shown, 

 while in one of our specimens there are no hairs on any of the papillae 

 of the cephahc half. This absence of hairs from some tubercles may 

 be due to imperfect specimens, but this occurs in citri Ashmead, 

 where it is normal. 



Pupa case (pi. 67, fig. 1). — Much resembles citri; size about 1.84 by 

 0.846 mm.; many of the cases, however, are smaller than the above 

 dimensions; shape elhptical, with sHght indentations on margin at 

 the pores of the tracheal folds; form flat, thoracic sutures plainly 

 visible as transparent lines oh the dark brown median area; abdom- 

 inal segments not distinct. Color transparent or yellowish, with a 

 median brown longitudinal area. This sometimes occurs only on the 

 thorax, and again it extends caudad to the vasiform orifice. Tracheal 

 folds (pi. 67, fig. 3) marked with minute dots, the pore located near the 

 margin and being without fimbriae, though with a distinct rim. 

 Vasiform orifice (pi. 67, fig. 2) cordate, somewhat rounded, with the 

 cephalic margin straight. The caudal margin is armed with 25 or 30 

 rather well-defined fimbriae or teeth; size of orifice 0.039 by 0.039 mm.
