the female nymphs in which they are encysted and often remain a long 
period. They are very common on newly cleared land. Heavy rains 
carry immense numbers to the shore, where they are frequently gathered 
with sea-shells and often strung as beads for necklaces, ete. This 
species was described by Guilding (Trans. Linn. Soc., London, 1833, p. 
115, pl. 1) as a parasite of ants, but it is probable that their relation te 
the ants is similar to that of other Coccide. A species M. vitwm, is de- 
scribed by Mayet (Ann. Soc. Ent. France, 1896. p. 419) as infesting the 
roots of the vines in Chili. Prof. Wheeler called attention to a new 
species of Margarodes recently described from southern Europe. 
Mr. Johnson referred to a recent paper by Prof. Stein (Wiener Ent. 
Zeitschr, XXIX p. 11, 1910) on the genus Fucellia. A study of all the 
material at hand from Labrador to Florida, shows only one species, refer- 
able to Ff. marina Macq. and not to F. fucorum Fallén. 
Prof. A. P. Morse gave a paper on “A Hopperdozer for Rough Ground.” 
This was illustrated by drawings of the apparatus which is designed to 
catch young grasshoppers when they are destructively prevalent as they 
are at times in New England and where the ground is so rough that any 
other device of this kind is useless. His suggestion that the plates be 
covered with “tanglefoot” used for banding trees was discussed by the 
members. 
Mr. Newcomb reported the occurrence of a noctuid moth flying on 
March 3rd. Dr. Reagh said that he had seen three moths flying on 
Feb. 22, and on the eighth of March took a specimen of Phygalia titea. 
Mr. Swett remarked on the records of the captures of Phygalia oliva- 
cearia and said that its occurrence seems to be limited to a few days 
about March 31st. Mr. Emerton showed two early spring insects, Chionea 
valga, a Tipulid fly with vestigial wings, found on snow at Three Mile 
Island, Lake Winnipesaukee, N. H., Feb. 21, 1910, and Capnia pygmea, a 
Neuropteriod insect on snow at Jackson, N. H., Feb. 21. 
The meeting then adjourned to the laboratory, where refreshments were 
enjoyed by all, through the kindness of Prof. Wheeler.
