nating about 8 8-shaped pores from the posterior pair of 8-shaped pores, nearly 

 as numerous as 8-shaped pores toward posterior end of row, usually one and 

 one-half times as numerous elsewhere. 



Dorsal surface : 8-shaped pores scattered except at posterior end, 10-16 /j. 

 long and 7-12 wide, the majority 12-16 /j. long and 10-12 wide; minute 8-shaped 

 pores numerous ; disk pores fairly sparse ; tubular ducts 24 fx long. 



Ventral surface : Antenna a circular, raised area with 2 setae as long as, and 



2 longer than, diameter of antenna ; beak broken, presence or absence of setae 

 indeterminable ; spiracle with bar triangular, atrium enlarged and containing 

 4 or 5 quinquelocular pores, 7-9 similar pores extending to body margin in a 

 single row; multilocular pores, with 7-10 loculi, arranged in 2 complete and 1 

 interrupted row, the posterior complete row with 11 and the other with 19 

 pores, the interrupted row with 2; 4 dark-rimmed 8-shaped pores each side of 

 beak, a few in lateral area of abdomen, and a few tending toward arrangement 

 in a transverse row anterior to multilocular pores ; submarginal 8-shaped pores 

 in a single row terminating near the posterior row of multilocular pores, nearly 

 as numerous as marginal 8-shaped pores ; submarginal setae in a complete row 

 terminating about one-half length of apical seta from bases of apical setae; 7 

 setae in posterior complete row of multilocular pores, 2 in anterior complete 

 row, and 2 anterior to those but posterior to interrupted row of pores. 



Apex of abdomen : Notch minute : lobes indicated, apparently on ventral 

 surface ; setae, apical 60-64 tx long, interapical 7.2 n long, a pair 1 /x long entad 

 of interapical on dorsal margin, intermediate and outer ventral (both nearly 

 anterior to apical) each 3.6 n long; anal opening ventral, very close to margin in 

 a slight indentation between lobes, circular, its margin membranous. 



Lama. — Nearly elliptical, posterior end narrowed. 



Margin : With 28 8-shaped pores, anterior pores slightly larger than the 

 others, axes of all longitudinal : a minute seta close to each pore of the posterior 



3 pairs ; 3 pairs of setae at anterior end. 



Dorsal surface : 8-shaped pores in a submedian row of 4-8 and a lateral row 

 of 9, on each half of body, with a total of 26-33, posterior pores of each row 

 the smallest, submedian pores about one-fourth larger than lateral and slightly 

 or distinctly smaller than marginal pores of same segments; 2 disk pores between 

 lateral and marginal 8-shaped pores. 



Ventral surface : Antennal setae. I, 1 : IV, 1 : V, 1 : VI, 3 long, 2 stout, 3 fairly 

 stout ; antennal bases one-half length of antenna apart ; beak setae, 2 pairs apical, 

 1 pair basal ; spiracle with 1 trilocular and 1 quinquelocular pore ; leg setae, 

 coxa 3, femur 1 on inner margin near base, tarsus 1 each on inner and outer 

 margins ; tibia one-fourth as long as tarsus ; apparently 9 pairs of submarginal 

 8-shaped pores ; apparently 9 pairs of submarginal minute setae, on abdomen, 

 thorax, and head : 3 pairs of setae between antennae and mouth parts. 



Apex of abdomen : Lobes sometimes indicated ; setae, apical 54 /x long, inter- 

 apical 5.4 fi long, a pair 1 n long entad of interapical, intermediate and outer 

 ventral (both nearly anterior to apical) each 1 \x long; anal opening in margin, 

 circular, its margin sclerotized. 



Data. — Described from one unmounted specimen, one mounted 

 female, and six mounted larvae on Caryota sp., Cerro del Galipan, 

 north of Caracas, Venezuela, August 15, 1891, U. S. N. H., holotype 

 and paratypes. 



In general appearance this species resembles boliviae and pdlmae, 

 but the absence of anal ring setae sets it off from these species im- 

 mediately. It can be segregated from any other known species in- 

 festing palm by the presence of numerous 8-shaped pores scattered over 

 the dorsal surface. 



Asterolecanium japonicum Cockerell 



(Fig. 34, C-K; pi. 7, M) 



Described by Cockerell in 1900 (22, p. 71) as a variety of 

 Asterolecanium, variolosum-, and raised to specific rank by Takahashi 

 in 1934 (95, p. 4). Although Takahashi based his action on a mis- 

 identification of specimens (those he placed as this species belonging
