Body thinly covered with a white secretion. Segmentation distinct. 

 Boiled in KOH, cleared and mounted in balsam, practically colorless 

 except around the area of the grouped spines, which is tinged with yel- 

 lowish-brown. These groups are variable in size and the spines are 

 conical in shape, short, stout and placed close together. The dorsum is 

 quite thickly beset with short conical spines and thin, not at all long, 

 hairs. These not uniform in length. Legs, mouth -parts and antennae 

 yellowish-brown. Legs long and stout, quite hairy. Middle leg coxa 

 320 long ; femur, with trochanter, 560 ; tibia, 500 ; tarsus, 200 ; claw, 60. 

 Antenna nine jointed, measuring as follows in length: [i) 120, (2) 120^ 

 (3) 140, (4) 76, (5) 80, (6) 88, (7) 80, (8) 92, (9) 140. Formula : (39) (12) 

 86 (57) 4. All the joints have short, thin hairs. Segments well marked 

 by suture. Mentum large, apical half with several long hairs. 



Had. — lyone Pine, California, on Atriplex. Collector un- 

 known. Sent to Prof. Cockerell, who turned it over to me. 

 Superficially it looks very much like a Dadylopiiis. On the 

 same plant were some Ceroplastes, probably C. irregularis Ckll. 

 new to California. 



Aspidiotus Hcdcrae in Australia. 



By James Lidgett. 



In September, 1899, I forwarded some species of Coccidse 

 collected in Victoria to Dr. L. O. Howard, including a species 

 of Aspidiotus in situ, which was quite unknown to me and 

 distinct from any of our Australian species. This material 

 was subsequently handed over to Mr. C. L. Marlatt to work 

 up, and recently I received from that gentleman a communica- 

 tion, in which he recognized the insect as Aspidiotus hederce 

 Vallot. 



This is the first time A. hederce has been discovered in the 

 Australian region, and is, therefore, another illustration of 

 how civilization is scattering over the earth's surface many 

 kinds of insects. I have not yet been able to ascertain the 

 name of the host plant, which is an exotic tree resembling 

 American ash. It was planted fourteen years ago from Mel- 

 bourne nurser)' stock. The trunk, branches and leaves were 

 infested, the $ scales being confined to the latter. 



By way of illustrating how scale insects may be — and, in- 

 deed, often are — disseminated, it may here be remarked that
