THE SCALE INSECT GENUS ASTEROLECANIUM L89 



1 lout: seta and 1 or 2 short setae: penis sheath very -leader, with 1 pair of 

 small setae dorsally near base, 2 pairs of large setae ventrally near base, and 



3 short, and a few minute, setae on each side of ventral opening. 

 Male nymph. — Distinguishing characters similar to those of adult male. 

 Thirdstagt male. — Elliptical: margin with 8-shaped pores in a complete row 



terminating near median line, the posterior 2 pores separated by twice the length 

 of a pore, the others about a pore's length apart, trilocular pores in a single row 



terminating near the posterior marginal 8-shaped pores. 1 near each 8-shaped 

 pore: dorsal surface apparently without minute 8-shaped and disk pores; ventral 

 surface with atrium of spiracle somewhat enlarged and containing 1 quinque- 

 locular pore, apparently sometimes with 1 quinquelocular pore also between 

 spiracle and body margin. 1 or 2 dark-rimmed 8-shaped pores each side of beak, 

 number of submarginal 8-shaped pores, submarginal setae, and areas represent- 

 ing legs indeterminable; apex of abdomen with apical setae apparently present 

 but broker:, other setae and anal opening not observed. 



Data. — Described from unmounted specimens and the following 

 mounted material: Six females. 7 larvae, and 1 adult male from 

 Attalea coJvune^ La Ceiba. Honduras, intercepted at New Orleans. La., 

 Benton and Kostal. November 24, 1920. including holotype : 1 female 

 and 1 larva from Attalea rohune. Puerto Sierra, Honduras. Percy Wil- 

 son. February 18. 1903. U. S. X. H.: 11 females, 19 larvae. 3 adult 

 males, and 1 male nymph from Attalea colwne, Honduras, inter- 

 cepted at Philadelphia. Pa.. W. J. Ehinger. April 25. 1928; 1 female 

 and 2 larvae from coconut palm. Honduras, intercepted at Xew Orleans, 

 La.. J. C. Pritchett. June 25. 193-1: 7 females, 23 larvae. 2 adult males, 

 and 1 male nymph from Palmae. Jamaica, intercepted at Philadelphia, 

 Pa.. M. Kisfiuk. July 6. 1934: 3 females. 3 larvae, and 2 third-stage 

 males from Attalea cohune. Honduras, intercepted at Xew Orleans. 

 La.. U. G. H addon. June 28. 1935: 3 females and 12 larvae from palm. 

 Honduras, intercepted at Washington. D. C. H. Y. Gouldman. Sep- 

 tember 11. 1935. 



Closely related to degeneratum, difficile, and wichi. Characters 

 distinguishing it from degeneration and difficile are discussed in the 

 treatment of those species. It is distinguished from vrichi by having 

 multilocular pores, and by the length of the apical setae, which are only 

 approximately as long as the ring setae. In no other species of the 

 genus have apterous males been observed. 



ASTEROLECANIUM SIMPLEX, new Species 



(Fig. 64. A-E; pi. 9, .4) 



Habit. — Living on stems. 



Test of female. — Elliptical, around 2 mm. long, 0.0 wide: convex dorsally, some- 

 times with 2 or 3 minute flattened tubercles on median line, posterior end some- 

 what flattened: slightly concave ventrally : pale brownish yellow, translucent, 

 dull, punctate; marginal filaments fragmentary, apparently whitish; elliptical 

 larval exit in dorsal surface at margin. 



Adult female. — Elliptical. 1.8 mm. long. 0.9 wide. 



Margin: 8-shaped pores in a single row terminating about a pore's length 

 from baSes of apical setae, posterior pores S-'.> n long and 5 wide, the others 

 Ui-ii n long and 5 wide, about a pore's width apart : quinquelocular pores in a 

 single row terminating with the 8-shaped pores, in the proportion of i to each 

 8-shaped pore and 1 for each interval toward posterior end. 3 or -1 to each S shaped 

 pore between spiraeular pore bands, and 2 or :> to each 8-shaped pore elsewhere. 



Dorsal surface 1 : Minute 8-shaped pores fairly numerous: disk pores rather 

 sparse: tubular ducts 30-32 ft long: dorsal tubes present. 



Ventral surface: Antenna jagged, conical, apparently with 2 setae as 

 as diameter of antenna: beak without setae: spiracle without a bar, the atrium 

 enlarged and containing t> or 8 quinquelocular pores, L5 20 similar pores extt 

 from spiracle to body margin in a double row: :i or 4 dark-rimmed 8-shaped |
