" Quite the same as A. pustulans, and ev'idently introduced by man. 

 The antennre are not really lo-segmented ; the apparent segments are 

 rings; compare certain Aphids and Psyllids" (Cockerell). 



Lecanium (Saissetia) hemisphaericum 7W;y. (Plate IV, 

 Figs. I 2-1 6.) 



Afdture female. — Length about 2.5 mm.; hemi.spherical in shape; color light 

 brown. After treatment with KOH, the female becomes transparent with the excep- 

 tion of the margin of the body which is golden-yellow. Under the microscope may 

 be seen many round, rather large pits all over the dorsal aspect ; mouth parts small : 

 antennae 8-segmented, .14 mm. long, terminal segment bearing many long fine hairs, 

 segment 3 longest, segment I next, then 8, segment 6 the shortest ; the proportional 

 length of antennal segments are as follows :

The three pairs of legs are subequal, strongly chitinized, coxa stout, longer than 

 wide ; tarsus shorter than tibia, digitules on tarsus fine and hair-like, knobbed ; dig- 

 itules on claw very large, of dumbbell shape, and extending beyond claws ; margin 

 of the body with fine forked hairs ; anal ring small with many hairs ; anal plates 

 small but heavily chitinized, bearing a few short hairs. 



Habitat: On Chicocca racemosa (60), Psychotria ni/ipes (117) 

 Tagus Cove, Albemarle Island and on Polvpodiutn squamatKin (499), 

 Chatham Island. 



" The scale looks like Seissetia hemisphicrica Targ. , and the anten- 

 nae and legs are not specially different. I think this is not to be 

 separated froin S. hemispluvrica " (Cockerell). 



Lecanium (Calymnatus) hesperiduin Z. pacificum, \ar. nov. 

 (Plate V, Figs. 17-22.) 



Mature feDiale. — -Length 2-3.5 inrn.; color pale yellow : elongate oval in form, 

 nearly flat, smooth. Under the microscope after treatment with KOH, the skin 

 shows but very few pits, irregular in size and distribution. Antennae 7segmented, 

 about .2 mm. long, segments, 4 longest, 3 next, 5 and 6 subequal and shortest, seg- 

 ment I thickest, wider than long, terminal segment bearing many long hairs, for- 

 mulae, 4, 3, 7, 2, I (6, 5). The proportional length of antennal segments are as 

 follows :
