posterior 11 pores the largest though slightly variable in size, next 2 the smallest, 

 the rest slightly larger than the latter but smaller than the posterior pores, 

 quinquelocular pores in a single row extending from anterior end of row 

 of 8-shaped pores to the eighth 8-shaped pore from posterior end of row, some- 

 what more numerous than corresponding 8-shaped pores ; dorsal surface with 

 10 8-shaped pores scattered on anterior end, mostly anterior to mouth parts, one- 

 third as large as posterior marginal pores, disk pores arranged roughly in 3 

 transverse rows of approximately 4 each ; ventral surface with spiracular bar 

 broad, derm outside spiracular opening slightly wrinkled, faintly sclerotized, and 

 containing 5 or 6 quinquelocular pores, 4 similar pores between these and mar- 

 ginal pores, legs represented by 3 pairs of faintly sclerotized circular areas 

 without claws, 8 8-shaped pores similar to those on dorsal surface at anterior 

 end, disk pores occurring posterior to mouth parts and in a submarginal row, 

 submarginal setae present on abdomen but number indeterminable, none ob- 

 served in median abdominal area ; apex of abdomen without setae but possibly 

 with setal bases, anal opening in ventral surface close to margin, apparently 

 nearly circular, anal tube apparently as in adult female, anal ring with 2 minute 

 setae, derm immediately surrounding opening sclerotized, rest of apex mem- 

 branous.

This is the only known species of Astevolecanium in which the entire 

 apex of the abdomen is heavily sclerotized. It is also unusual in having 

 large 8-shaped pores ventrally and in lacking ventral submarginal 

 8-shaped pores. 



Asterolecanium semisepultum, new species 



(Fig. 63, A-E; pi. 8, T) 



Habit. — Living on both surfaces of leaves, and imbedded in the leaf tissue, the 

 dorsal surface of the test on a level with the surface of the leaf, the tissue 

 surrounding the test slightly raised. 



Test of female. — Nearly circular, posterior end slightly produced ; around 0.5 

 mm. long, 0.45 wide; flat dorsally, with distinct transverse striations, strongly 

 convex ventrally ; pale brownish yellow, transparent, shiny ; marginal filaments 

 not observed ; elliptical larval exit in dorsal surface at margin. 



Adult female. — Nearly circular, ventral surface so much larger than dorsal 

 surface, because of its greater convexity, that the whole extent of the slide- 

 mounted insect is larger than dorsal surface ; 0.5-0.65 mm. in diameter. 



Margin : 8-shaped pores in a single row which is probably normally complete 

 and which terminates the length of an apical seta from setal bases and the pores 

 once to twice a pore's length apart, but with considerable variation due to
