Eggs, according to Professor Parrott, are deposited during July on 

 small twigs, in oval patches about 4 or 5 mm. in diameter. Hatching 

 occurs in early autumn and the tiny caterpillars remain sheltered 

 through the winter under the protecting egg mass. It is consequently 

 much easier to find the nearly full grown caterpillars in June than 

 to detect the rather inconspicuous egg masses and the hidden cater- 

 pillars at the time nursery stock is usually imported. The ermine 

 moths are considered abroad as very destructive fruit tree pests and 

 are forms which should be excluded from this country. 



Saturnia pavonia Linn. One specimen of the dark reddish brown 

 cocoon of this Bombycid was found on nursery stock at Eochester, 

 N. Y. The cocoon is 3.5 cm. in length, 2.5 cm. in diameter and with one 

 end somewhat produced and partially open. The moth has a wing 

 spread of 7.5 cm., is smaller than our well known Calosamia prome- 

 thea Drury, and the coloring is mostly in shades of gray with distinct 

 ocellate spots on both the anterior and posterior wings. There should 

 be no difficulty in excluding this rather large species. 



Monarthropalpus biixi Lab. This European box leaf midge was 

 found by Prof. A. E. Stene in May, 1910, infesting a box hedge, 

 Buxus sempervirens, at Kingston, R. I. Galls received May 25 pro- 

 duced an abundance of midges, the insects completing their trans- 

 formations in the galls and on emerging left their whitish exuviae 

 protruding. It would not be surprising were this European species 

 to be found in other parts of the country. The insect undoubtedly 

 became established in this country by the importation of infested box 

 trees. 



Gall. This is a more or less irregular, oval swelling of the leaf, 

 with an eccentric, oval, clear space excavated by the yellowish larvae. 

 There is a very slight elevation of the leaf with an irregular, yellow- 

 ish or brownish discoloration, the margin of the enlargement being 

 indicated by a darker green. The' gall is most easily seen by trans- 

 mitted light. 



Adult. The rather large, yellowish orange midges have a length 

 of 2 to 2.5 mm. in the male and female, respectively. Antennal seg- 

 ments 14, the flagellate binodose in the male; the female having the 

 fifth with a stem about one half the length of the cylindric basal en- 

 largement. These midges are easily separated from Hormomyia by 

 the mesonotum not projecting over the head, and from their other al- 

 lies by the uniarticulate palpi. 



Detailed descriptions will be published in the authors' monograpji 

 on this group.
