232 OUTHEZIA UETICJE. 



(fig. 4) large, circular, exterior thickly set with, minute 

 glandiferous spines ; marginal abdominal spiracles 

 (fig. 5) tubular, rather long, and much smaller than 

 the ventral series. Anal orifice (fig. 3) large, with six 

 rather long hairs, ring broadly and regularly punctured. 

 Gland-tracts almost continuous ; glandiferous spines 

 (fig. 6) rather long, curved, and bluntly pointed. 

 Dermis between the gland-tracts with numerous 

 spinnerets and a few scattered slender spines. Mentum 

 biarticulate, basal joint shortest. 



Long, 4-6 mm. 



Larva, after treatment with potash, rather short 

 ovate, and narrowed posteriorly. Gland-tracts form- 

 ing transverse bands, narrowly separated; glandiferous 

 spines like those of the adult female, but smaller. 

 Antennas (fig. 8) of six joints ; formula usually 6, 3, 2, 

 1 (4, 5) ; the last joint is much the longest and bears 

 an apical spine. 



Habitat. Douglas ('Ent. Mo. Mag.,' I.e., p. 176) says: 

 " This Orthezia is not scarce in the larva state, in 

 August and September, in many places, on various 

 plants." The only food-plant named is Stellaria 

 holostea. In July, 1895, I found the larvae swarming 

 on Glaux maritima. Old adult females, with empty 

 marsupia, were plentiful on the same plant, and also 

 on Statice armeria, grass, etc. I have not met with 

 the species elsewhere ; it is, apparently, a local insect. 



Distribution. Common in many parts of Europe. 

 It is said to feed upon a large number of plants, chiefly 

 of the orders Urticaceas, jEuphorbiacede, and Labiate. 

 Miss L. E. Tomlin found it abundantly at Courmayeur, 

 Italy, in August, 1895, chiefly on composites and 

 labiates. Mr. Brockton Tomlin has quite recently 

 (May, 1903) collected the species at Cape Sunium, 

 Greece. His specimens consist chiefly of male pupaa 

 in various stages of development.
