America ai'e : New York, i ; Arizona, 

 I ; Oiclahoma, i ; Colorailo, i ; Kansas, 

 2; California, 3; Massachusetts, 4; 

 Mexico, I ; and one variety from 

 Texas. Although Kcrmcs were known 

 before the time of Moses, there were 

 none described from America until 

 Jnne, 18S1. A brief synopsis of the 

 species follow in the order in which 

 they were originallv described. 



I. Kermes galliformis Riley, iSSi. A 

 large, dark, dirty gr.iy form, which turns to 

 a nearly clear white color when exposed a 

 season on the twigs. ? scale 6 mm. long, 7 

 broad, 6 high, with black spots, and viewed 

 with a hand lens the scale is seen to be cov- 

 ered with minute black specks. Newdy 

 hatched larva dirty gr,\y. See tables. Origi- 

 nally described from Iron Mountain, Mo., 

 and Silver City, New Mexico, the latter col- 

 lected by Mr. H. H. Rusby, on J^iiercus 

 emoiji, also recorded from Colorado, Florida, 

 Connecticut, South Carolina, and Massa- 

 chusetts. A new locality is Las Vegas, New 

 Mexico, March, 1900 (Cockerell and Porter).

la. Kermes galliformis^ var. cucroeiisis. 

 Cockerell, n. var. " Large, transverse 

 diameter 8 mm., convex, with no medi- 

 an constriction ; brownish-white, obscurely 

 marbled with very pale gray, with linear 

 transverse brown bands, somewhat wavy, 

 and thickened at intervals; surface minutely 

 speckled with brown dots. On small 

 branches of post oak {^iierciis sp.), at 

 Cuero, Texas, June 2, 1898, collected by 

 Prof. C. H. T. Townsend" (T. D. A. Cock- 

 erell, MS.). 



After my MS. was sent to the printer 

 Prof. Cockerell sent me some of the young 

 larvae of the above variety, and I lind them 



very different from any yet described, and 

 belong to the galliformis group; the follow- 

 ing is a description of them. 



$ larvae light yellow, elongate oval, 400 

 long, 200 broad. Antennae 6-jointed, 3, 6 

 and I equal in length and longest, 2, 4 and 



5 equal and short, nearly as broad as long. 

 All the measurements are in micromilli- 

 meters, joints (i):;o (2)12 (3)20 (4)12 (5ji2 

 (5)20. Formula (36i)(245), i, 4 and 5 have 

 two short bristles. 6 seem to have about 

 nine or ten, two of these at the apical and 

 very long. Marginal spines point backward 

 and slightly curved, not very stout, i;; long. 

 Caudal tubercles long, each with a long 

 bristle 140 long, and three stout spines 20 

 long. Legs normal Avith the coxa 20 long. 

 Femur with trochanter, 64; tibia, 28; tarsus, 

 48; claw, 16. Coxa, 36 broad. Femur with 

 trochanter, 28; tibia, 16; tarsus, 16. The 

 tarsus diminishes in breadth rapidly near the 

 claw. Digitules of tarsus and claw normal, 

 with small knobs. Mentnm and rostral 

 loop tinged with yellow, all the other parts 

 are colorless after boiling in K. l\. O. 



2. Kermes gil/e/lei Ck\L, 1895. ? scale 

 8 mm. long, 7.5 broad, 7 high. Segmenta- 

 tion distinct, dorsum with round tuberosities, 

 general coloring white and dark brown mot- 

 tled, usually with a white dorsal band. 

 Young larva pale purplish pink. Antennae 



6 jointed, 3 and 6 equal and longest, 4 and 5 

 equal and shortest and about as long as 

 broad, 2 a little longer than 4 and much 

 shorter than 3, 3 about as long as 4 plus 5. 

 Formula (36) 2 (45). Described from Mani- 

 tou, Colorado, on ^iierciis muiulaia. Coll. 

 by Prof. Gillette, Nov. 26, 1894, also found 

 in New Mexico, in Santa Fe Canon (Cock- 

 erell), and at Beulah (Cockerell and Porter, 

 March, 1900).
