8 PEOCEEDINGS OF THE NATIONAL MUSEUM vol.71 



margin of the body; no tiny simple pores definitely observed; anal 

 region very slightly protruding, anal lobes broad, hardly differenti- 

 ated, inner faces somewhat chitinized, usually with a small ventral 

 thickening; ring somewhat invaginated and with a narrow collar 

 above; anal ring with pores and six setae, these about 32)a long; 

 apical seta more than 50/>i long, one moderately stout seta within 

 apical seta about KV, and two slender ones below it about 6/^ long. 



Larva (Embryonic). — Very similar to that of stypheliae^ but Avith 

 the intermediate row of 8-shaped pores on each half of the body 

 nearly or quite complete, instead of almost wholly lacking as in 

 stypheliae. 



Described from a very few mounted specimens taken from the 

 Maskell collection material. The original collection source of these 

 specimens is uncertain and could not be determined from Maskell's 

 descriptive notes. It seems at least a possibility that these specimens 

 may represent the Tasmanian material Avhich Maskell assigned to 

 the species stypheliae. 



Holotype and paratypes. — Cat. No. 40361, U.S.N.M. Paratypes 

 also in Maskell collection of Coccidae located with the New Zealand 

 Department of Agriculture. 



The species is evidently very closely related to Asterolecanium 

 stypheliae Maskell. It appears to differ definitely in certain respects, 

 jncluding the distinctly broader test and body, the larger number of 

 quinquelocular disk pores in each of the rows between spiracles and 

 margin (from 12 to IT instead of from 6 to 9), and in the reduction 

 in the extent of the chitinization on the anal lobes.

The Maskell collection contains four slides labeled as this species, 

 one of " 3 adult females, 1894," one of " adult female, 1894," one of 

 " test of female, 1894," and one of " larva, 1894." The larva is quite 

 plainly an Eriococcine form, and consequently, can be given no fur- 

 ther consideration. The remaining slides are in fair condition, so 

 that it has been possible to check them against mounts which have 

 been made from the unmounted specimens included in the collection 

 under No. 423. Two species are very evidently present of which that 

 described by Maskell as being on dark red bark and having a test 

 with pinkish fringe, since it is mentioned first, is to be taken as the 

 true ventruosmii and the specimens from such bark as the type speci- 

 mens. The description which follows is restricted to these specimens. 



Adult female. — See Maskell publications for description of test 

 and other points in the external appearance; body, as mounted, ap-
