purpose I have found are the so-called Riker mounts. This type of 

 mount does not permit one to see both sides of the insect but allows 

 the removal of the top for a more careful examination of all parts of 

 the specimen. If the above mentioned writer, "C," has a better mount 

 I would be interested to receive a sample. A. N. CAUDELL, U. S. Na- 

 tional Museum, Washington, D. C. 



QUESTION No. 2. I wish to ask the opinion of entomologists as to 

 which is the best way to keep overwintering pupae that pupate in the 

 ground. Should they occasionally be moistened and if so how often?

ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS 

 OF THE GLOBE. 



Argyresthia thuiella Pack, in New Jersey (Lep.). 



This species, known as the Arbor vitae leaf miner, has a much more 

 extended distribution in New Jersey than is generally supposed. 

 Smith in his Cat. Ins. of N. J., p. 554, lists it only from Essex Co., 

 (Kf.). As a matter of fact, it occurs in many of the large nurseries 

 in the northern part of the state and is undoubtedly being further 

 distributed by them. The larvae mine the terminal sprays, the tips 

 of which eventually turn brown. In severe infestations, which how- 

 ever appear to be rare, the foliage has a rusty, brownish appearance, 

 detracting much from its ornamental use. Light infestations escape 

 the attention entirely of most nurserymen, who assume that the dis- 

 colored tips are due to root troubles or adverse weather conditions.

Agrilus viridis L. in New Jersey (Col.). 



An account of the occurrence of this member of the family Bupres- 

 tidae in New Jersey and its damage to Rosa rugosa can be found in 

 the Jour. Econ. Ent., Dec., 1914. Inasmuch as I said nothing in this 

 account concerning its life history, it might be well to state that 

 Theobald in his bulletin on The Animal Pests of Forest Trees, gives 

 beech, alder, birch, aspen and oak as food plants and states that the 

 adults appear in June and July and fly in bright sunshine. Eggs are 

 deposited singly on the bark near the ground and the larvae live 

 under the bark, boring in the sap wood and into the wood itself, liv- 

 ing in the trees for two or three winters and pupating in April or 

 May. It attacks healthy as well as unhealthy saplings. Its long larval 

 period makes it an unsatisfactory insect to breed out in the laboratory 

 and accounts for the few adults which I obtained from many infested 

 stems. It was evidently introduced into New Jersey in woody roses 

 or shade trees imported from Europe. HARRY B. WEISS, New Bruns- 

 wick, New Jersey.
