anal tube either absent or very short; anal opening and tube sometimes not 

 differentiated from anal ring, which is close to or actually on the surface ; ring 

 represented by a somewhat elliptical plate, sclerotized on 1 side only in a narrow 

 band connecting bases of 2 setae 9-10 /a long ; a sclerotized collarlike area 

 inclosing a minute pore at base of each seta ; a circular opening in curve of 

 sclerotized band similar to opening in center of circular anal rings ; ventral 

 surface of apex, near margin, slightly sclerotized and rugose. 



Larva. — Elliptical. 



Margin: With 28 8-shaped pores, axes of all diagonal or transverse; a pair 

 of minute setae close to each of the posterior 3 pairs of pores ; 3 pairs of setae 

 anteriorly. 



Dorsal surface : 8-shaped pores in a lateral row of 9 on each half of body, 

 uniform in size or anterior pores slightly larger than the others, at least three- 

 fourths the size of marginal pores; disk pores between dorsal and marginal 

 8-shaped pores. 



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

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

 apical, 1 pair basal; spiracle with 2 trilocular pores; leg setae, coxa 2, femur 



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

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

 minute submarginal setae, on abdomen and thorax, 2 pairs of submarginal larger 

 setae at anterior end ; 3 pairs of setae between antennae and mouth parts. 



Apex of abdomen : Setae, apical 30 n long, interapical 7.2 fj. long, outer ventral 



2 fi long ; anal opening minute, in margin ; anal tube very short, barely evident ; 

 anal ring a circular sclerotized band almost on surface, with 2 setae 1.8 m long. 



Data. — Described from tests, 3 mounted females, and 2 mounted 

 larvae on Maximilliana sp., Esmeralda, Venezuela, G. H. Tate, No- 

 vember 8, 1928, N. Y. B. G., paratypes; tests, 2 mounted females, and 

 10 mounted larvae on Cocos nucifera, Bahia, Brazil, intercepted at 

 Philadelphia, Pa,, W. J. Ehinger, January 12, 1934, holotype and 

 paratypes. 



This species appears to be a degenerate form closely resembling 

 urichi, simile, and difficile. It differs from urichi in having multi- 

 locular pores, and apical setae the same length as the ring setae ; from 

 simile in having marginal 8-shaped pores extending across the apex 

 of the abdomen, in having fewer marginal trilocular pores with none 

 across the apex of the abdomen, and in having only 4 or 5 multilocular 

 pores, and from difficile in having at least 8 marginal 8-shaped pores 

 across the apex of the abdomen, in lacking a sclerotized heart-shaped 

 plate composing the anal ring, as well as in having the ring setae 

 practically the same length as the apical setae, and in having only 5 to 



8 pores in the atrium of each spiracle. 



Asterolecanium delicatum (Green) 



(Fig. 18, K-N; pi. 8, A) 



Described briefly in 1896 (40, p. 5) as Planchonia delicata, and re- 

 described and placed in Asterolecanium by Green in 1909 (42, v. 332) . 



Hal) it. — Living on the lower surface of leaves. 



Test of female. — Nearly elliptical, posterior end sometimes rather pointed ; 

 2-2.5 mm. long, 1.25-1.5 wide ; flat or very slightly convex dorsally, with a faint 

 longitudinal median carina, flat or slightly convex ventrally : bright brownish 

 yellow, transparent, fairly thin, finely punctate ; marginal filaments very pale 

 yellow ; elliptical larval exit in ventral surface close to margin. 



Adult female.- — Shape similar to that of test, 1.7-2.25 mm. long, 1-1.4 wide. 



Margin : 8-shaped pores in a single row terminating around twice length of 

 a posterior pore from bases of apical setae, anterior pores 13-14 n long and 



9 wide, the others 12-13 /* long and 7-8 wide, nearly contiguous; 6-8 quinque- 

 locular pores where each spiracular pore band meets body margin, usually 1 

 opposite each 8-shaped pore at these points; disk pores dorsad of, and less 

 numerous than, 8-shaped pores.
