apart; beak setae, 2 pairs apical and 1 pair basal; spiracle witb 1 trilocular and 

 1 quinquelocular pore, or with 2 quinquelocular pores; leg setae, coxa 3, femur 

 1 on inner margin near base, tarsus 1 each on inner and outer margins; tibia 

 one-half as long as tarsus; 9 pairs of submarginal 8-shaped pores; apparently 

 9 pairs of submarginal minute setae, on abdomen and thorax, 1 pair of sub- 

 marginal larger setae at anterior end ; 3 pairs of setae between antennae. 



Apex of abdomen : Notch minute; lobes sometimes indicated ; setae, apical 45 /a 

 long, interapical 5.4 /* long, outer ventral (outside apical on margin) apparently 

 about 2.5 fi long ; without anal opening, anal tube, or anal ring. 



Data. — Described from unmounted material (paratype) and the 

 following mounted specimens collected on Attalea cohune : One female, 

 "Monte Cachirulo," Guatemala, April 1869, U. S. N. H., paratype ; four 

 females and one larva, Livingston, Guatemala, O. F. Cook, April 7, 

 1902, U. S. N. H., paratypes; one female, Puerto Sierra, Honduras, 

 Percy Wilson, February 18, 1903, U. S. N. H., paratype; nine females 

 and nine larvae. La Ceiba, Honduras, intercepted at New Orleans, La., 

 Benton and Kostal, November 24, 1920, holotype and paratypes. 



This species is unusual in having a large number of multilocular 

 pores segregated into groups within a row, and an extremely large 

 number of dark-rimmed 8-shaped pores, also arranged in groups on 

 the abdomen. It is the only species observed by the writer in which 

 the eggs are deposited in a thick mass of curly filaments that are thrust 

 out of the test through a splitting of the entire posterior margin. 



Asterolecanium elongatum, new species 



(Fig. 20, Q-U; fig. 21, A, B; pi. 7, D) 



Habit. — Living along midrib on upper surface of leaves. 



Test of female. — Lanceolate, 2.25-3 mm. long, 0.4-0.5 wide ; so strongly convex 

 dorsally that the raised area along median line appears as a strong carina with 

 slightly concave sides, flat ventrally ; pale yellow or light brownish yellow 

 translucent, dull, slightly punctate ; marginal and dorsal filaments rich golden 

 brown, the marginal ones slightly longer at anterior end than elsewhere, the 

 dorsal ones extending along median line and varying in length from half to quite 

 the width of test ; larval exit not apparent. 



Adult female. — Lanceolate, 2.25-2.85 mm. long, 0.45 wide. 



Margin : 8-shaped pores in a single row terminating about four times the 

 length of a posterior pore from bases of apical setae, posterior pores 8-9 ii 

 long and 4 wide, increasing in size to 12 fi long and 6 wide at anterior end, the 

 width to the length of a pore apart near posterior end, but almost contiguous at 

 anterior end; quinquelocular pores in a single row terminating between the pos- 

 terior pair of 8-shaped pores and apical setae, 3-6 posterior to posterior 8-shaped 

 pores, at least as numerous as 8-shaped pores near posterior end, elsewhere one 

 and a half to two times as numerous. 



Dorsal surface : 8-shaped pores arranged in a group of 3 close to anterior 

 margin, and in a single row extending along median line nearly to apex of body, 

 irregularly spaced, 54 counted in 1 specimen and 58 in the only other mounted 

 specimen available, the smallest pores 12-13 n long and 6-7 wide, but the majority 

 20 fi long and 12 wide; minute 8-shaped and disk pores fairly numerous; tubular 

 ducts 36 fi long; dorsal tubes present. 



Ventral surface: Antenna thimble-shaped, with 2 setae as long as diameter 

 of antenna; beak without setae; spiracular bar fairly broad; derm around 

 spiracular opening wrinkled, expanded, cup-shaped, and containing 4-9 quin- 

 quelocular pores, ]3-19 similar pores extending from spiracle to body margin in 

 a row 3 or 4 pores wide; 1 dark-rimmed 8-shaped pore each side of beak, 6 or 8 

 in median area arranged in 3 or 4 groups anterior to genital opening, and a few 

 scattered in lateral area ; submarginal 8-shaped pores in a single row terminating 

 near the thirteenth pore from the end of the marginal row and about one-half 

 as numerous as marginal 8-shaped pores; apparently (> pairs of submarginal 

 setae on abdomen, the posterior pair near the fifth pore from the posterior end of
