New Mexico Coccide of the Genus Ripersia. 53 
This is an ordinary-looking form, with antenne much as 
in R&. candidata, King, ined., but it is of a different colour 
from that species and occupies a different region. It differs 
from R. flaveola by having the third joint always longer than 
the second, whereas in flaveola these antennal joints are equal 
in length. &. Kingit is a pink species with a superficial 
similarity to confusella, but the antenne are decidedly 
different *, 
In &. confusella and R. candidata the fourth antennal 
joint is always decidedly the shortest; in R. Kingii it is no 
shorter than the fifth, or, at any rate, is not noticeably the 
shortest joint of the antenna. Prof. Tinsley gives the 
following formule for Kingit:—6 (12)543; 631 (245); 
Gran, By (5 4). 
Ripersia fimbriatula, Ckll. & King, ined. 
Hab. Las Vegas, in nests of Lastus americanus, often in 
the same nests as f. confusella. Also at Santa Fé. 
Hasily distinguished by its small size (about 1170 uw long), 
uniform yellow colour, and fringe of cottony tassels all round 
the body. Antenne 6-jointed. 
Ripersia flaveola, Ckll. 
-Hab. Las Vegas, N. M.; originally described from Massa- 
chusetts. 
The following particulars refer to specimens taken at Las 
Vegas with Lasius interjectus, April 30, 1901 :— 
2? .—Length a little over 13 millim.; light orange, thickly 
covered with white meal; caudal lobes quite prominent ; 
bristles of anal ring 89 w; middle legs with tibia 102, tarsus 
72; antennal segments:—(1) 36-39, (2) 42, (38) 42-45, 
(4) 36, (5) 80-33, (6) 33-36, (7) 75-84. This accords well 
with Mr. King’s measurements of Massachusetts specimens. 
The antennal formule of Las Vegas specimens are 7 3 2 1 
4 (5 6) and 7 (2 8) (14.6) 5. Prof. Tinsley has found the 
formule 7 2 (43) (1 6) 5 and 72 5 1 (6 3) 4in Massachusetts 
material. 
Ripersia Portere, sp. n. 
9? .—Globose, very pale pinkish or sometimes yellowish : 
mounted specimen 2? millim. long and 24 broad; enclosed in 
a snow-white sac just like that of Dactylopius lichtenstoides.
