two stout spines ; anal ring with six long hairs; legs (Plate V, Fig. 6) very stout, 

 tarsus less than half as long as the tibia, well armed with spines and hairs as indi- 

 cated in the figure ; claw stout, strongly curved, the four digitules present. Anten- 

 n?e (Plate V, Fig. 7) eight-segmented (some specimens show a tendency of the 

 eighth segment to divide, see Fig. 7), length .36 mm.; formula, 8 (32), i (20), 2 

 (i8),3(i6), 5(13), 7(i2),4(ii), 6(10). 



Larva ( Plate V, Fig. 8). — The newly hatched larvce are of a transparent whitish 

 color and about .9 mm. in length; antennre seven-segmented, formula, 7, 3, i, 2 

 (4, 6), 5. Legs about the same as in the adult female, except more slender; body 

 hairs, spinning glands, spines, etc., as in the adult. 



The Egg. — The eggs are rounded oval, dark yellow and about .3 mm. in length. 



Male. — Not known as yet. 



Habitat. — In April, 1901, a few specimens of this species were 

 discovered by the author, on some herbarium specimens of Cupressus 

 viacnabiana, which were collected by Professor W. R. Dudley, of 

 Stanford University, near Clear Creek, four and one half miles west 

 of Shasta P. O., Shasta Co., Cal., July 19, 1899. As Cupressus 

 macnabiana is a very rare cypress, being known but from three or 

 four localities in the state, I paid a visit to the locality above men- 

 tioned, Aug. 29, 1 90 1, and found the adult, with young insects very 

 abundant. 



The trees on which this coccid are found are situated at an ele- 

 vation of about one thousand feet in a little flat, in a dry, sandy, 

 chalky soil, and consists of about a dozen small trees, not more than 

 ten feet in height. Several of these trees were literally covered with 

 the insects and none was free from them. This is the only locality 

 from which they have been obtained. 



Named for Professor W. R. Dudley, of Stanford University. 



Note. — D. ryani Coq., also found on cypress in California is not 

 the same, it having the last antennal joint 99 ;/ ; penultimate joint 

 47 p.. It is also larger and differently colored. (Ckll.)

 Aspidiotus californicus, sp. nov. 



Scale of Female. — Length about 2 mm., width about l mm.; oblong-oval and 

 rather conical in form ; color blackish with pale edges ; exuvii^ central, reddish- 

 brown. (An examination of hundreds of specimens shows a great variation in form 

 and size ; where crowded together on the tree they are small and more nearly circu- 

 lar in outline, but where only a few are on the tree they are larger and more oblong 

 in shape. ) • 



Adult Female. — Length about .9 mm., width about .65 mm.; egg-shaped ; color 

 light greenish-yellow ; eyes rather large ; antenna; reduced to a single large, flat, circu-
