811 A. EF. Verrilli— The Bermuda Islands. 399 
? Chaff-scale. (Parlatoria Pergendii Comstock, Annual Rep. Dep. 
' Agric. for 1880, p. 327, pl. xi, fig. 4; pl. xx, fig. 5.) Figure 185a. 
Mr. C. V. Riley (Bulletin No. 15, U. 8. Dep. Agric., Entomol. 
Diy., 1887) states that this species was introduced into Florida from 
Bermuda about 1855, but perhaps he had in mind Mytilaspis citri- 
cola, concerning which the same statement had long before been 
made by Glover (see note, p. 808), for this species was not described 
until 1880. I do not know that it has been otherwise recorded, 
though it may well occur. 
Aspidiotus Maskelli Cockerell ? 
Mr. Geo. A. Bishop, in a recent letter, states that this species 
infests the orange and other citrus fruits, fig-tree, and Japanese 
privet (Ligustrwm ovalifolium). It was first described as native o1 
the Hawaiian Islands, and has since been recorded from Mauritius 
and Brazil (t. Banks). It feeds on MWalva and other plants. The 
Bermuda form may possibly be some other closely related species, 
perhaps A. awrantii Mask. See Fig. 184, d. 
Figure 185a.—Chaff-seale (Parlatoria Pergandii); a, female scale; 6, male scale; 
enlarged; after Comstock. Figure 186b.—San José Scale (Aspidiotus 
perniciosus); a, females; b, males; c, d, young; after Comstock. Figure 
187.—Onion Thrips (Thrips tabaci); b, larva, all much enlarged. From 
Webster’s International Dictionary. 
For convenience of comparison I add cuts of several other species 
of Scale-insects that infest the orange trees in Florida and Califor- 
nia. Perhaps all or most of them occur in Bermuda. Figs. 184-186. 
Hitherto none of the various small Ichneumon-flies that destroy 
aphids and scale-insects in N. America and other countries have 
been found in Bermuda. Like the useful Lady-bugs, they might be 
introduced with great profit.
