area there is a row of spines forming a ring about the case. These 

 are variable in length, the longest being about 0.19 mm. On the 

 subdorsal area there is a row of smaller spines, four on each side of 

 the thorax and four on each side of the abdomen. These are all small 

 but the most caudal pair, which is as long as those of the submar- 

 gmal ring. On or near the median ridge there are the following spines : 

 One pair of small ones in about the middle of the thorax; one pair of 

 very small ones on the first abdominal segment; one pair of long 

 ones on the second abdominal segment; and just cephalad of the 

 vasiform orifice two pairs of moderately long spines, the spines of 

 the most caudal pah' situated close together, and the other one on 

 each side of the median ridge. The vasiform orifice (fig. 8) is situated 

 on a well-marked tubercle which forms the caudal extremity of the 

 median ridge. It is rounded or subcordate, and its inner margm is 

 armed with a series of folds. The operculum almost entirely fills the 

 orifice obscuring the Imgula. Just cephalad of the orifice there is a 

 pair of minute setae. The margin is dentate, the teeth bemg of 

 moderate size and swollen at thek- tips ; in this character resembhng 

 those of mangiferae. A space of 0.1 mm. is occupied by 13 teeth 

 (fig. 7). Around the margin near the base of the teeth there is a 

 row of minute tubercled setae. The case under the microscope is 

 dark brown, particularly so near the margms. On the leaf it is 

 shining black with httle or no dorsal secretion and a narrow white 

 waxen marginal frmge.

ALEUROCANTHUS CITRICOLUS (Newstead). 



Aleurodes citricola Newstead, Jlitteilungen aus den Zoologischen Museum in 

 Berlin, vol. 5, Heft 2, 1911, p. 173. 



We have seen no examples of this species. 



Puparium. — Elongate ovate; black and slightly glossy when free 

 from exuviae of previous moults. Dorsum may or may not be keeled ; 

 with one bilateral, subdorsal row of large spines, and one submarginal 

 row; the latter projecting beyond the secretionary margin, in some 

 instances; these spines are generally laden at the tips with irregular 

 nodules of almost colorless secretion. Marginal fringe broad, white, 

 and practically homogenous. In most cases the dorsum is partly 

 hidden by the exuviae of the previous moult; these are paler in color 

 than the puparium of the adult, but they are free from secretionary 

 matter. Ventral margin or flange (fig. 1) very narrow, inner edge 

 deeply crenulated, but the crenulations are generally rendered ob-
