THE SCALE IXSECT GENUS ASTEROLECAXIUM 101 



Larva. — Nearly elongate elliptical, posterior end narrowed. 



Margin: With 2S 8-shaped pores, the posterior pores very slightly -mailer than 

 the others, axes of the posterior G pairs of pores transverse, of the others longi- 

 tudinal; a pair of minute setae close to each of the posterior 3 pairs of | 

 2 pairs of setae anteriorly. 



Dorsal surface: 8-shaped pores, totaling 42-44. in a submedian row of 11 and 

 a lateral row of 10 or 11. on each half of body, the anterior pores slightly larger 

 than posterior ones and practically same size as marginal pores of same seg- 

 ments, the posterior pores usually slightly larger than the marginal pores of the 

 segments on which they occur : a disk pore near each of posterior and penultimate 

 marginal 8-shaped pores and near anterior 8-shaped pore of lateral row. 



Ventral surface: Antennal setae. T. 2: IV. 1: V. 0: VI, 2 long, 2 stout, 3 fairly 

 stout. 2 slender; antennal bases one-fourth length of antenna apart; beak setae, 

 2 pairs apical. 1 pair basal: spiracle with 2 trilocular pores: leg setae, coxa 4. 

 femur 1 on inner margin near base and 1 each on inner and outer margins near 

 center, tarsus 2 on inner and 1 on outer margin ; tibia one-half as long a- arsus : 

 6 pairs of submarginal 8-shaped pores, none between antennae; apparently 10 

 pairs of submarginal minute se:ae. on abdomen and thorax, 2 pairs of submar- 

 ginal larger setae at anterior end: 1 pair of setae between antennae and mouth 

 parts. 



Apex of abdomen : Notch present ; lobes indicated ; setae, apical 108 fi long, 

 interapical 12 /jl long, dorsal 3 u long, inner ventral 3.4 u long, outer ventral 3.6 

 a long: anal ring with 6 setae, each around 23 m long, and an inner row of 6 and 

 an outer one of 12 or 14 pores ; ventral surface of apex sclerotized in dentate rows, 

 or rugose. 



Data. — De-cribed from unmounted material and the following 

 mounted specimens : One female on Yucca sp.. Phoenix. Ariz.. A. E. 

 Frazier collector, February 5. 1935. loaned by G. F. Ferris; 3 females 

 and 10 larvae on Agave sp.. Phoenix. Ariz.. C. D. Lebert. July 24. 

 1935. including holotype: 7 females. 5 second-stage specimens, and 

 5 larvae on Yucca sp.. Phoenix. Ariz.. C. D. Lebert. January 6. 1936; 

 2 females and 14 larvae on Idria colurrmaris, Mexico, intercepted at 

 San Ysidro. Calif.. C. L. Ritchie. September 24. 1936: 11 females and 

 2 poor larvae on Cactaceae. Xew Mexico, intercepted at Blvthe Quar- 

 antine Station. Calif.. December 23. 1937 (1 loaned by G. F. Ferns). 



Closely related to viridulum^ but with fewer marginal quinque- 

 locular pores, with median dorsal 8-shaped pores larger than the 

 majority of the marginal 8-shaped pores, and with all setae in the anal 

 area, except the ring setae, much longer than in viri&ulvm. 



Asterolecaxium gutta Green 



(Fig. 2S, F-Mj fig. 29, A-F; pi. 3, G) 



Described in 1922 (40. pp. 1036-1036). 



Haljit. — "Ou young branches of Calophyllum walker i: Pattipola." 



Test of female. — Nearly circular, or slightly longer than wide, posterior end 

 slightly produced; around 3 mm. in diameter, or 2.5-3.5 mm. long. 2-3 wide: 

 strongly convex or hemispherical dorsally, flat or slightly concave Neutrally: 

 greenish or clear yellow, opaque owing to a waxy secretion inside test and with 

 a honeycombed appearance resulting from position of eggs in waxy secretion, 

 smooth, shiny: marginal filaments rubbed off; larval exit circular, in dorsal 

 surface of produced area. 



Adult female. — Nearly circular or broadly ovoid, posterior end slightly pro- 

 duced; 2-3 mm. in diameter. 



Margin: 8-shaped pores in an irregularly double row terminating around 

 twice length of apical seta from bases of setae, -paces between pores usually 

 about equal to the length of a pore but sometimes less or much more, pores in 

 the double row mostly alternating, but when opposite, less than a pore's length 

 apart, of unusual shape. 12-15 /j. long and wide and their halves closely ap- 

 pressed ; pores with 5-9 loculi in a single row (sometimes crowded and appearing 

 double for short spaces), interrupted posterior to the last pair i^' 8-shaped pores
