is (3 [August, 



Scale of the ? circular, exuviae central, or nearly so ; the first exuviae in the 

 form of a "nipple-like prominence" (Comstock), covered with white v^ax in fresh 

 specimens, but red-brown or golden red-brown in denuded specimens ; nipple sur- 

 rounded by a circular depression, following this is a strong circular ridge, which, in 

 many specimens, is covered with the same white material as the nipple ; these are 

 situate on a distinct cii'cular prominence, or boss, with nearly perpendicular sides ; 

 below this the scale becomes very flat and wide, and is of a rich orange-brown, 

 varying to ochreous-brown. Diam., 1 — li mm. 



Scale of the J of the same colour, and has the same structure at apex as 

 the ?. 



Mr. Morgan, in his description of A. dictyospermi (I. c), states that the $ scale 

 is " greyish-white, with exuviae in the centre, depressed, of an elongate-oval shape." 

 Thus, it will be seen that the type differs very considerably in external characters 

 from the var. described above ; the arrangement of the marginal appendages of the 

 last segment and spinnerets of the $ , however, agrees in every way, both with the 

 description and figure given by Mr. Morgan ; so that, in spite of the diverse 

 character of the scale, I do not feel justified in considering it to be a new species. 



ASPIDIOTUS COCOTIS, n. sp. 

 Scale of the ? circular, white or yellowish- white, flat ; exuviae very large, central. 



Diam., 1 — 1^ mm. 

 ? (fig. 1) with three pairs of email lobes, median pair broadest, slightly re- 

 cessed, very slightly indented on their outer lateral margins ; second pair emarginate 

 on outer lateral margin ; thii'd pair of nearly uniform width throughout. There are 

 two plates between each of the first and second lobes ; three between the second and 

 third ; and beyond this there are seven or eight plates : two or three of which are 

 serrated. All the plates, however, are most difficult to determine, and it is only in 

 a few specimens that they can be traced at all. There are no spines or groups of 

 spinnerets in any of the specimens examined. 



Botli scales and insects are very badly infested with fungi ; the 

 latter to such an extent that the form of the body cannot be ascer- 

 tained. I was hoping that the species might prove the A. destructor, 

 of Signoret, which is said to be very injurious to palms, but there is 

 no resemblance between them. 



Sah. : on Cocos nucifera, cocoa-nut palm, to which it must be 

 very destructive, judging from the number of scales present upon 

 the leaves. 



ASPIDIOTFS AFEINIS, }l. Sp. 



Scale of the ? high convex, slightly elongate, or more or less circular, greyish- 

 brown ; exuviae a little on one side, covered with a pale reddish-brown wax, which, 

 when removed, exposes a sharp "nipple" of a brown colour, very like ^. ra^aa;, 

 Comstock. 



The ? has three pairs of lobes (fig. 2) : median pair convergent, very large, 

 deeply notched on the outer lateral margin, and sometimes slightly so on the inner
