comparison with the illustrations and description of the latter 

 species (Coccidae of Ceylon, pt. Ill, 1909, p. 331, and pi. CXXII, 

 fig. 1-5) by having the discal paired pores slightly but distinctly 

 smaller than the largest marginal paired pores, the marginal row 

 of unpaired glands single, except at a few points, and by having 

 a more or less distinct faded salmon-colored fringe on the margin 

 of the test, and a test more elongate in proportion to its width. 



The following details and corrections may be added to the 

 original description of this species as given by Prof. Cockerell 

 (Can. Ent. XXXIV, 1902, p. 89). 



Adult Female. Test in unmutilated specimens with a relatively wide, 

 straight, continuous fringe of faded salmon color, and with a considerable 

 quantity of dirty curled-thread secretion over the uniformly convex dorsum; 

 marginal paired glands in a double row as stated in the original description, 

 except on about the posterior fifth of the body, where the row is single; with 

 the marginal paired gland pores varying slightly in size, but with some of 

 them, at least, larger than the discal paired gland pores; with numerous 

 dorsal paired gland pores scattered without apparent order over the dorsal 

 surface of the body. 



Young Larva. Elongate oval, tapering behind, antennae and legs small, 

 the former 6-segmented, with a complete marginal and median double row 

 of paired gland pores, and an incomplete intermediate row of the same on 

 each side; anal ring with 6 small hairs, surrounded by 4 chitinized plates 

 making up a ring, on each side of which projects one short and outside of 

 this one long hair; tarsal claw straight, sharply bent at extreme tip. 



Statements as to details of structure at variance with the 

 original description have been verified by an examination of the 

 type slide of the species, deposited by Prof. Cockerell in the 

 National Collection of Coccidae. 



Genus Birchippia Green. 



Birchippia americana Leon. 



(PI. 4, fig. 4.) 



The specimens of this species in the Jorgensen collection are 

 from Cordillera de Mendoza, Argentina, on Larrea divaricata, 

 Feb. S, 1909, under collection number u'a. 



It may be noted with reference to the original description of this 

 species (Bol. Lab. Zool. gen. e agr. R. Scuola sup. d'Agr. Portici, 

 vol. V, 1911, p. 240-248, fig. VI), that Dr. Leonard! gives B. 

 anomala as the species heading in the explanation of his figures, 

 but this is apparently incorrect, since the drawings agree with his 

 description of B. americana, and do not agree with Green's figures 

 and descriptions of B. anomala. The genus Birchippia Green 

 appears to be separable from Solenococcus Cockerell only by the 

 absence of a median caudal tubercle, between the uniu-d anal
