THE CANADIAN KNTOMoLOGlsT. 



Aspidiotus rapdx (Comst.). 



Two specimens of what seem to be this species on a weed from Flint 

 Island. 



Aspidiotus lierculeanus, n. sp. (Fig. 8). 



Female puparium: Scales extremely inconspicuous, resembling the 



bark and often covered, with the 

 bark, by a green mould. Exuviae 

 indicated by a white ring with a dot 

 in the centre. Exuviae pale yellow 

 in colour, not noticeable with the 

 insect in situ. 



Male puparium (?) 



Adult Female : Rather large, cir- 

 cular, dark brown in colour. Abdo- 

 minal segments usually distinct. 



Pygidium : Median lobes large, 

 very close together, rounded at the 

 apex, and strongly notched on the 

 outer side. Second lobes represent- 

 ed by very small, inconspicuous 

 processes ; no other lobes present. 

 Median lobes strongly chitinized, 

 the chitinized base projecting far 

 into the pygidium. A long, narrow 

 chitinized portion extending anteiior to the base of the lobes, and two 

 shorter curved ones across the pygidium, near the base. 



Lobes followed by a series of large, strong spines, varying in number, 

 but usually from 8-10. A single pair of spines some distance anterior to 

 the first series. 



A very large club shaped gland opening at the outer base of each 

 median lobe; these glands about 200/1 long, with a round club-shaped 

 end ; the tube swollen, fusiform. The second pair of claviform glands, 

 close to the first, represented by a minute rudiment. Laterad of the 

 second lobe is a pair of small fusiform glands. 



No circumgenital glands. Anal orifice close to the base of the 

 median lobes. Arranged in a somewhat regular row, laterad of the 

 chitinized portion of the pygidium, and scattered irregularly at the bases 

 of the lobes are a number of cylindrical, tubular spinnerets, suddently
