Coccida. 
Aspidiotus graminellus, sp. 1.

with pale yellow exuviz, which are covered, and surmounted 
by a white boss. 
3 .—Scale white, elongate, Déaspis-like in outline, convex, 
shiny, not in the least keeled, with the wholly covered pale 
yellow exuvia at one end. 
?.—Yellow; after boiling in potash colourless, mouth- 
parts and caudal end remaining brown; anal orifice oval, 
about 21 « long and 36 wu from bases of median lobes; dorsal 
glands comparatively tew, in four longitudinal rows on each 
side; no circumgenital glands; three pairs of lobes, the 
median ones large, rounded, well apart; second and third 
lobes low and broad, the inner side perpendicular, the outer 
long and gently sloping, the apex rounded ; chitinous thick- 
enings at the bases of the lobes. 
Embryo in female about 280 w long. 
Hab, On leaves of grass, producing purple blotches ; Las 
Vegas, N. M., Jan. 6, 1901; first found by Wilmatte P. 
Cockerell. 
The scale is quite after the manner of A. Gutierrez, but 
the female insect is different. It differs from Gutierrezie in 
the rounded, wide apart, median lobes, the much larger blunt 
second and third lobes, and the dorsal glands, which are few 
aud in rows, instead of being numerous and scattered. The 
anal orifice in Gutierrezi@ is scarcely 12 w long. 
Orthezia occidentalis, Douglas. 
Beulah, N. M., March 1900; common on a very damp 
hillside. New to New Mexico. 
Antonina graminis, Parrott. 
Las Vegas, N. M.; on grass, limestone-ledges by the 
Gallinas River, Jan. 12, 1901 (W. P. & T. D. A. Ckil.).
