THE SCALE INSECT GENUS ASTEROLECANIUAI 185 



quinquelocular pores extending from opening to body margin; an area without 

 pores completely surrounding spiracle but a double or Triple row of quinque- 

 locular pores in a circle surrounding clear area except occasionally when the 

 pores extend in a direct line to a point before anterior spiracle instead of curving 

 and completing the circle; 8-shaped pores similar to those on anterior part ,,f 

 dorsal surface usually scattered anterior to beak, and 2-5 rarely posterior to 

 beak; approximately of the same size and number as those on dorsal surface; 

 submarginal row of 8-shaped pores absent; apparently 6 pairs of submarginal 

 setae on abdomen (5 pairs in membranous area and 1 in sclerotized area) ; 2 

 setae posterior to genital opening, usually 6 in successive pairs anterior to 

 opening. 



Apex of abdomen: Heavily sclerotized; setae, apical 12 fj. long, others normally 

 absent but sometimes a minute seta close to 1 apical seta; anal opening apical, 

 circular ; anal tube sclerotized near opening, membranous on inner half, slightly 

 larger in center than at ends ; anal ring a sclerotized band with 2 setae about 



2 n long. 

 Second stage. — Ovoid; margin apparently with 12 pores on each side of body, 



posterior pores largest, gradually decreasing in size anteriorly, quinquelocular 

 pores between spiracular pore bands; dorsal surface with 5 or 6 8-shaped pores 

 at posterior end, smaller than anterior marginal 8-shaped pores ; ventral surface 

 with bar of spiracle fairly broad, area around spiracular opening membranous, 

 4 or 5 pores between opening and body margin, a few disk pores in a submarginal 

 row on abdomen, setae indeterminable ; apex of abdomen too poor for deter- 

 mination of structures. 



Larva. — Ovoid. 



Margin : With 18 8-shaped pores, situated on abdomen and thorax, posterior 

 pair the largest, the others gradually decreasing in size to anterior pair, which 

 is one-half as large as posterior pair, axes of all practically longitudinal, except 

 sometimes axes of the posterior and the anterior pairs transverse or diagonal ; 



3 pairs of setae at anterior end. 



Dorsal surface : One or 2 8-shaped pores each side of median line on thorax, 

 about the same size as anterior marginal pores ; disk pores in lateral area. 



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

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

 1 pair median ; spiracle with 1 quinquelocular and 1 quadrilocular pore ; leg 

 setae, coxa 4, femur 1 each on inner and outer margins near center, tarsus 2 on 

 inner and 1 on outer margin ; tibia one-half as long as tarsus ; 2 pairs of sub- 

 marginal 8-shaped pores, 1 pair posterior to antennae and 1 pair posterior to 

 anterior spiracles; 12-16 disk pores in a submarginal row extending from near 

 anterior marginal 8-shaped pores to a point 2 or 3 8-shaped pores before posterior 

 8-shaped pore ; 6 pairs of submarginal minute setae on abdomen, 2 pairs of sub- 

 marginal larger setae at anterior end ; 1 pair of setae between antennae and 

 mouth parts. 



Apex of abdomen ; Lobes indicated ; setae, apical 40 ^ long, interapical approx- 

 imately 3.6 ft long; anal opening an elongate incision in margin; anal tube short, 

 sclerotized, bulbous ; anal ring a sclerotized band with 2 setae around 4.5 /j. long ; 

 derm around opening sclerotized in a small rectangular area. 



Test of male. — Elliptical, 0.75 mm. long, 0.45 wdde ; dorsally slightly convex 

 anteriorly and flat posteriorly; flat ventrally ; pale brownish yellow, transparent, 

 fairly thin; marginal filaments apparently same color as test*, fragmentary. 



Adult male. — 0.75 mm. long. 



Head: Antenna 9-segmented, formula (longest to shortest), (IX), (HI, V. VI. 

 VIII), (IV), (VII), (II), (I) ; antennal setae, I, 2; II, 12; III-IX, 10-18; VII 

 and IX also with 1 stout seta, very long setae not observed on ninth segment : 

 basal bars curved; 12 setae anterior to ventral eyespots. 



Thorax: Bar between wing bases curved on anterior margin, three times as 

 long as wide, with a faint longitudinal median fold; tibia very slightly longer 

 than tarsus. 



Abdomen: Three segments each apparently with a seta dorsally on lateral 

 margin, apparently 2 segments each with a seta in ventral lateral area; each 

 lobe area with 1 rather short seta ; penis sheath apparently without setae on dor- 

 sal surface, 6 large setae on each side of ventral opening near base. 3 or 4 

 smaller setae nearer tip. 



Third-stave male.— Elongate void ; margin with 27 8-shaped pores on each side 

 of body, extending from a transverse line drawn through anterior part of mouth 

 parts to within once or twice a pore's length from bases of apical setae, the
