 of 12 pores, and divided on dorsal side and tending toward division on ventral. 



Larva. — Elliptical. 



Margin : With 28 8-shaped pores, anterior pair slightly larger than the others, 

 axes of all longitudinal ; 3 pairs of setae anteriorly. 



Dorsal surface : On each half of body a submedian row of 3 or 4 8-shaped pores 

 and sometimes 1 pore laterally, anterior submedian pore slightly larger than the 

 others and two-thirds the size of marginal pores of same segment ; disk pores in 

 submarginal area and a few in lateral area. 



Ventral surface : Antennal setae, I, apparently 1 ; IV, 1 ; V, 1 ; VI, 2 long, 2 

 stout, 3 fairly stout, 1 slender ; antennal bases one-half length of antenna apart ; 

 beak setae, 2 pairs apical, 1 pair basal ; spiracle with 1 trilocular and 1 quinque- 

 locular pore ; 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 as tarsus ; 9 pairs of submarginal 8-shaped pores ; 6 pairs 

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

 anteriorly ; 2 pairs of setae between antennae and mouth parts. 



Apex of abdomen : Notch shallow ; setae, apical 62 fi long, interapical 9 fi 

 long, inner ventral (fairly close to median line) 3.6 //. long, outer ventral 5.4 t*

 6 and an outer row of 12 pores, and divided on dorsal and ventral sides. 



Data. — Kedescribed from unmounted material and the following 

 mounted specimens: One female on bamboo, Japan, I. Kuwana, 5-X- 

 1913, from E. E. Green, possibly type; 11 females on bamboo, New 

 Orleans, La., E. R. Sasscer, March 9, 1919; 6 females on Bambusa sp., 

 Taihoku, Taiwan (Formosa), R. Takahashi, January 1928, possibly 

 type material of tuberculatum; 2 females on PhyUostachys bambu- 

 soides, Keijo, Chosen, S. Nakayama, November 3, 1928; 1 female and 2 

 larvae on bamboo, Ocean Springs, Miss., H. Gladney, April 12, 1929; 

 8 females and 2 larvae on bamboo, Japan, intercepted at Philadelphia, 

 Pa., A. B. Wells, December 19, 1932. 



In the paper containing the original description of bambusicoJa 

 Kuwana (-5 J, p. llfl) published the following note: 



With regard to this species, Prof. Green has given me the following remark : 

 "This resembles A. bambusae Bdv. superficially, but differs from that species 

 in several important particulars. In the first place the marginal fringe is of 

 a bright pink color. I note that the marginal series of paired glands is single 

 on the abdomen but irregularly double on the thorax. There are numerous simple 

 circular glands immediately within the paired series, and bands of similar pores 

 connect the stigmata with the margin. There are no supplementary paired 

 glands on the dorsum." The writer should state here that he has not been able 

 to recognize the double series of paired glands on the thorax, mentioned by 

 Prof. Green. 



As shown by Kuwana, there is no indication of a double series of 

 marginal 8-shaped pores on the thorax or elsewhere on the margin. 

 Green might have been dealing with another species, or notes concern- 

 ing two species might have become confused. 



In the description of tuberculatum Takahashi mentioned a "trans- 

 verse tubercular ridge across about the middle of the scale." The 

 ridge is characteristic of the test, and appears as two tiny humps 

 immediately anterior to an imaginary transverse median line. 



Asterolecanium bellum, new species 



(Fig. 8, A-L; pi. 3, E) 



Habit. — Living on bark, usually in shallow pits, and occasionally on the lower 

 surface of leaves. 



Test of female. — Circular or nearly ovoid, 0.9^1 mm. in diameter ; convex dor- 

 sally, with or without faint transverse striations, posterior end flattened and often 

 upturned, flat or slightly convex ventrally ; greenish, brownish, or, rarely, clear
