THE CANADIAN ENTOMOLOGIST. 75 



Aspidiotus pseudospiiiostcs^ n. so. (Fig. lo) 



Scale. — The scale of the femile is ci'cular, or somewhat oval, slightly 



conve.x, 1.5-2 mm. in diameter ; covered by a brown fungus. 



Female. — The female is brownish-yellow, nearly circular, about .58 



mm. broad by .6 mm. long. '\\\t pygidium is furnished v\'ith two pairs 



of lobes. The mesal lobes are large, widely separated {5-6 //,), parallel, 



distinctly notched on both outer and inner sides, rounded at end, about 



I 2- [4 \i. broad by 12-13 /^ 'of^g- Lobes of the second pair are much 



smaller than the mesal lobes, entire or slightly notched on outer side. 



Incisions are wanting. Plates are well developed They are situated as 



follows : Two between the mesal lobes, two between the first and second 



lobes, and six to ten laterad of the second lobe. The interlobular plates 

 and the first three Literad of the second lobe are branched ; the remainder 

 are simple, unbranched. Spines are large. On the dorsal surface they 

 are situated as follows : One at the outer side of the base of the mesal 

 lobe, one at the base of the second lobe, one just beyond the third plate 

 laterad of the second lobe, one just beyond the last plate, and one at the 

 anterior border of the pygidium. The first three spines are as long as or 

 longer than the plates. Spines on the ventral surface are similarly 

 situated ; wanting at the mesal lobes. Spinnerets are in four groups ; 

 anterior laterals 5-7, posterior laterals 3-6. U'he anus is large, and 

 situated at the caudal end of the pygidium, about 28-33 /x from base of 

 mesal lobes. The vaginal opening is between anterior and posterior 

 lateral groups of spinnerets. The pores are large, in two rows on each 

 side of pygidium ; 6-10 pores in each row. Dorsal tubular spijinerets 

 are present, short, irregular, or seldom in two rows on each side, about 

 15-20 on each side. 



This species is closely related to A. spinosus, Comst., from which it 

 differs mainly by the presence of dorsal tubular spinnerets. The mesal 

 lobes are not prolonged inward as in spinosus, and are more widely 

 separated (2-3 /x in spinosus). The plates also differ. 



Habitat. — -The specimens were taken from Saw Palmetto, collected 

 in Florida by \V. H. Field in 1882, and since ha\e been in the collection 

 of the Entomological Department of Cornell University. 



Types of the two above described species are in the Entomological De- 

 partment of Cornell University, and the U. S National Museum.
