never been satisfactorily demonstrated. If, as held by some, 
kraunhiae and citri are synonymous, the Hawaiian insect repre- 
sents a very widely spread and polyphagous species. On the 
other hand, the distribution of typical kraunhiae is very lim- 
ited, it being confined to Japan and California outside of Hawail. 
Once it was recorded from quarantined plants in New Jersey, 
but the record lacks confirmation. ‘The Hawaiian insect is 
heavily parasitized by Leptomastidea abnormis as well as by 
Pauridia peregrina and is the prey also of other polyphagous 
mealy-bug enemies. It is, therefore, of much less significance 
as an agricultural and horticultural pest than some of the other 
mentioned species, although occasionally a heavy infestation will 
be observed. 
Ferris has described the morphological characteristics of both 
species in his paper on “The California Species of Mealy-Bugs” 
(loc. cit.), and figures the distinguishing characters. A good 
illustration of P. citri as it appears in nature, which might well 
pass for P. kraunhiae also, is found in connection with Sanders’ 
paper on “The Identity and Synonymy of Some of Our Soft 
Scale Insects” in Jn. Econ. Ent., Il, p: 428: 
Pseudococcus longispinus (Targ.).: 
This is another tropical or subtropical species of wide dis- 
tribution and with a wide range of host plants. It is particu- 
larly a greenhouse pest, flourishing most luxuriantly in a warm, 
still, moist atmosphere. Ferris treats this species in his paper 
on “The California Species of Mealy-Bugs”’ (loc. cit.), describ- 
ing the morphological characteristics and giving figures of the 
important characters. Sanders, in a paper on “The Identity 
and Synonymy of Some of Our Soft-Scale Insects” (loc. cit.), 
gives an excellent illustration of this mealy-bug as seen in 
nature. Green also describes and figures the species in Pt. V 
of the Coccidae of Ceylon.
