A NEW COCCID FROM CALIFORNIA AT A VERY HIGH 



ALTITUDE. 



BY EDW. M. EHRHORN, MOUNTAIN VIEW, CAL. 



Exceretopus caricis, n. sp. 



Adult 9 salmon pink, shiny, about 2 mm. long and 1 mm. broad, 

 elongate oval. Legs and antennae light brown. $ secretes a mass of 

 cotton all over her body, becoming so dense as to completely envelope 

 the entire body, looking more like an elongated Eriococcus. This 

 secretion extends caudad, forming a large egg-sac, which, including the 

 whole insect, measures from 4 to 5 mm. Eggs salmon pink. Young 

 larvae orange colour. Adult $ after boiling in K. O. H. derm remains 

 light brown. Margin beset with fine, short, straight spines, incisions 

 having two stout curved spines. There are numerous short conical 

 spines scattered over the derm with irregular rows of long fine hairs. 

 Anal plates large and thick, each with four short, stout spines. Anal ring 

 with six very long, stout hairs, which extend to caudal end of plates. 

 Antenna long, slender, tapering, 8-jointed. Joint 3 always longest and 

 joint 7 always shortest, each joint with one or more fine hairs, joint 8 

 with several long hairs. Formula: 3.4. 5. S. (1.2.) 6. 7.

 curved clubs, about 32/;.. Legs not very hairy, trochanter with a long

H a b — On stems of Trisetum subspicatum, (L.) Beauv., and Carex 

 Brewer/, Boott. Mt. Shasta, above timber line, September 3rd, 1901. 



Note. — I have placed this interesting species in Exceretopus owing 



to its two-jointed tarsus. The only other species known is E. 



formiceticola, Newst. (The Ent. Mo. Mag., Vol. V., p. 204), and differs 



very much from the above species. E. caricis abandons the food-plant
