HUN'IER: the COCCIDA', of KANSAS. 
Five groups circumgenital 
glands. Caudo-laterals 6 to g, 
cephalo-laterals g to 14, anterior 
o to 2. (Majority of specimens 
show I or 2 glands in anterior 
position.) 
Four groups circumgenital 
glands. Caudo-laterals 8 to ii, 
cephalo-laterals g to 14, anterior 
group wanting. 
The fifth group of glands, greater number of plates and spines, 
and additional well chitinized incision on margin of anal plate, to- 
gether with peculiarities of the scale, are differentiations worthj' of 
consideration in forming a specific separation. I prefer for the 
present, however, to place solus as a sub species, and have allied 
it to cesculi on account of similarity in contour of margin of anal 
plate of female. Later I hope to be able, with A. Juglandis, A. 
/uglans-regi(e, var. pruni, var. albus, var. kafka and A. cesculi before 
me, to establish the exact position of solus. 
Mytilaspis pomorum Bouche. 
The scales longer than measurements given in description, being 
2)4 to 3 mm. Structure of female conforms with typical forms. 
Found upon the outer branches of two apple trees in one locality. 
Lawrence, Kans. 
Diaspis snowii, nov. sp. Plate VIl, Figs. 31, 32, 33. 
Scale of female. Flat, oval, 2 by 3 mm., exuviae laterad of center 
on the shorter axis. Scale sometimes more nearly circular and 
more regular in outline, then exuviae appear to be located nearer 
margin. Margins ragged. Central portion of scale dark gray, 
pallid on border, scale very flat approaching margin so that the 
connection between scale and bark is not readily discerned. A 
very delicate ventral scale. 
Scale of male. White in fresh specimens, orange white in older 
specimens, i mm. long, narrow, rounded longitudinally, but slightly 
carinated. Exuviae orange yellow, terminal. Some specimens 
not quite so long and broader. The mature male has not yet been 
observed. 
Female. Oval, lemon yellow. Anal plate extended but little 
beyond the general shape, orange, ^ell chitinized. Anal orifice 
situated at base of aperture between median lobes. 
Circumgenitals, five groups, caudo-laterals 5 to g, cephalo-later- 
al.s 8 to 15, median o to 2. 
One pair lobes, notched on outer margin, two incisions on each 
side showing chitinous processes.
