margin of the case (fig. 5). The distance from the caudal extrem- 

 ity of the orifice to the caudal margin is four and one-half times the 

 length of the orifice. On the dorsum there are a number of minute 

 clear circular spots, but from the condition of the specimen it is 

 difficult to give the number or arrangement of these. The balsam 

 mount stiU shows traces of a marginal wax fringe. Type in the 

 MaskeU collection. 



Adult. — Unknown. 



Habitat. — In India, on Saccharum officinale. The specimens were 

 collected by the late Mi-. Cotes, of the Indian Museum, Calcutta, from 

 Baroda, who reported that they were rather damaging to the sugar cane 

 in those parts. 



ALEUROLOBUS FLAVUS, new Bpecies. 



Plate 42, figs. 1-8. 



This species was collected by R. S. Woglum on an unknown tree in 

 the Royal Botanic Gardens, Ceylon, in October, 1910, and by A. 

 Rutherford on Lorantlius, Peradeniya, Ceylon, May 27, 1913. It is 

 represented by pupa cases and eggs only. 



E'^r^r.— The egg (fig. 7) is 0.224 mm. long and 0.096 mm. wide. It 

 is stalked at its larger end and slightly curved at the smaller end. 

 It is yellowish brown in color and some specimens are covered with a 

 waxy reticulation, which reticulations are 0.18 mm. in diameter. 

 This apparently may be destroyed in preparing mounts. 



Pupa case (fig. 1). — Size 1.28 by 0.976 mm.; form broadly eUip- 

 tical; color light yellowish brown to almost transparent. There is 

 no waxy secretion of any kind. Dorsal disk separated from the mar- 

 ginal area by a delicate fine all around, just within which is a heavily 

 chitinized wavy fine (fig. 3); nearer the margin and within the sub- 

 marginal area some specimens show a dehcate fine all around, but 

 the presence of this is not constant. The body segments are distinct 

 on the dorsal disk, and the median area of this disk is dehneated from 

 the lateral areas by wavy lines, as indicated in the figure. There are 

 also upon the median area of the dorsum four longitudinal rows of 

 minute pores and several others irregularly placed on the marginal 

 portion of the dorsal disk. Three or four pairs of similar pores are 

 also present on the thorax. The submarginal area is marked with a 

 large number of irregular fines, extending mesad from the margin, 

 which is crenulate (fig. 6). The thoracic breathing folds are quite 

 distinct on the margin and terminate in three rather prominent 

 rounded teeth (fig. 2). The vasiform orifice (fig. 4) is triangular, 

 and longer than broad ; its inner caudal margin is armed mth a number 

 of tooth-hke projections. The operculum is similar in shape with, 

 and almost entirely fills, the orifice. The lingula (fig. 5) is elongate, 

 swollen toward the distal end, setose, and armed with two stout
