Some New Coccidae. 



By Geo. B. King, Lawrence, Mass. 

 To-day, April nth, I have just received a very pretty and 

 distinct ant-nest species of coccid from Prof. Cockerell, for 

 which he suggests the name Riper sia fimbriatiila, giving also 

 some descriptive names. 



Ripersia fimbriatuU n. sp. Ckll and King. 



$. — Small, oval, i>^ mm. long, i broad, of a light yellow color, with 

 a marginal fringe of cottony filaments and the entire body coated with 

 white powder. Placed in alcohol, they are light, delicate yellow tinged 

 with green. Boiled in caustic potash, they turn to a bright red-brown 

 color. The internal juice being removed, the derm is colorless ; mouth- 

 parts, antennae and legs light yellow. Antenna six jointed, with the 

 sixth longest, then three. One 4- two next and equal. Five is a little 

 longer than four, which is the shortest. Formula, 63(12)54. Measure- 

 ments of the several joints: (i) 40, (2) 40, (3) 56, (4) 20, (5) 32, (6) 76. 

 All of the joints have short, thin hairs, those on the sixth being somewhat 

 longest. Legs stout, quite bristly ; middle leg, coxa 48 long. Femur, 

 with trochanter, 160 ; tibia, 88 ; tarsus, 76 ; claw 20, broad ; coxa, 100 ; 

 trochanter, 60 ; tibia, 36 ; tarsus, 28. Claw thin, sharp, not much curved. 

 Digitules of tarsus and claw minute, indistinct, with small knobbed ends. 

 Anal ring normal, with the usual six but thin bristles. Caudal tubercles 

 small, with one short hair. 



Hab. — Las Vegas, New Mexico, April 7, 1901, in nest of 

 Lasius atncricana Em. under rocks ; collected by Mrs. Wil- 

 matte P. Cockerell. Also found last year at Santa Fe, N. M., 

 by Mr. T. D. A. Cockerell, but the material too scanty for 

 description. This .species is quite different from a yellow spe- 

 cies found in ant nests in Massachusetts, Ripersia Jiaveola 

 Ckll., which has practically seven jointed antennae and is 

 larger, although we find some individuals with only six joints, 

 measuring as follows : joint (i) 40, (2) 44, (3) 44, (4) 36, (5) 

 28, (6) 72. R. fimbriatula seems to be nearer to a species with 

 six jointed antennae, which was mixed with a lot of coccids 

 from ants' nests in Massachusetts found by me and described 

 by Prof. Cockerell in Can. Entom., 1896, p. 223, as R. lasii, 

 the latter having jointed antennae. I propose to call this six 

 jointed form, which is certainly distinct, Ripersia candidata 

 King. Although the antennal formula of this species is 

 nearly the same as that of Ripersia fimbriatula, the respective
