THE CANADIAN ENTOMOLOGIST. 65 



of similar, but smaller, \V\\.s, about ten in number, no two close together ; 

 sides abruptly descending, with submarginal and marginal rows of pits, 

 the submarginal quite large, the others very small. Margin with scattered 

 hairs. On the under side is a small amount of mealy secretion, arranged 

 in radiating lines upon the sides of the abdomen. In some specimens the 

 back is more or less coated with an easily deciduous waxy material. 



Mouth-parts small, labium rounded. Margin with long bristles, and 

 numerous very broad and rather short palraated or bifid plates. Antennae 

 stout, very small and pale, 5-jointed, with a long 3, or 6-jointed by the 

 division of 3, in which case 4 is longer than 3, being a trifle longer than 

 broad, while 3 is conspicuously broader than long. Legs stout, small and 

 pale; tarsus and tibia subequal, but tarsus a little the longer; claw large, 

 strongly hooked. Anal orifice dark brown, consisting of a circular 

 chitinous plate, in which is a large quadrangular opening filled by two 

 subquadrangular plates, each of which has on its surface a pair of 

 darkened rounded processes or lobes, and also a pair of foramina, the 

 foramina of the anterior plate near its anterior margin, and those of the 

 posterior plate near its posterior margin. The hind margin of the anterior 

 plate is concave, leaving a slit between the two. No bristles are apparent. 

 Skin with many minute circular gland orifices. Ventral surface in the 

 abdominal region with a transverse fold fringed with hairs. 



Larva (from body of 9 ) broad-oval, with a similar dorsal anal 

 orifice, but it is surrounded by the six long bristles of the anal ring. The 

 anterior plate, which bears these bristles, is horseshoe-shaped, with the 

 opening directed backwards, and into the opening falls the more or less 

 oval posterior plate, which is longitudinally divided in the middle line, 

 and no doubt represents the anal lobes. Margin with bristles and large 

 flattened bifid or trifid plates as in the adult, only they are much larger 

 in comparison with the size of the insect. Antennte stout. 



/:/al>. — Cameroons, W. Africa; very numerous specimens in alcohol, 

 collected by Dr. Yngve Sjostedt, of the Naturhistoriska Riksmuseum at 

 Stockholm. Several of the bottles are only labeled as from the 

 Cameroons; a few contain more exact labels — " Itoki, Feb., 1891"; 

 " Eskundu," and " Bonze." This is the first Coccid on record from 

 the Cameroons.
