PROCEEDINGS OF SCIENTIFIC SOCIETIES. 
ENntomoLocicaL Society or Lonpon. 
September 1, 1880.—H. T. Srainton, F.R.S., Vice-President, in the 
chair. 
Miss Emily A. Smith, Assistant State Entomologist of Illinois, of 
Peoria, Illinois, was ballotted for and elected a Foreign Member. 
Mr. J. Jenner Weir exhibited a male Odonestis potatoria having two- 
thirds of the upper wings of the yellow colour of the female, and a female 
of the same species of the usual dull red colour of the male: also a male 
Smerinthus Populi, having the wings almost without markings, and of the 
light colour generally found in the female, the right antenna being clubbed 
at the extremity, and not pointed as usual. 
Sir Sidney Saunders exhibited six winged examples of the Stylopideous 
genus Hylechthrus, five having been obtained from the specimens of 
Prosopis rubicola exhibited alive at ‘the last meeting, one of the latter 
having produced two of the former. Four adult larve of males were found 
in another of the same bees which became arrested in its development in 
the pupal stage. He also exhibited several of these bees having females of 
Hylechthrus in situ, and the puparium of a male extracted entire with the 
imago enclosed therein; also various Hymenoptera obtained from the same 
briars, among which were specimens of the Chalcideous genus Melittobia, 
and a new species of Scleroderma. 
Four other species of Sclererdoma from Greece are recorded in Professor 
Westwood’s monograph of this genus published in the second volume of 
the ‘ Transactions,’ 1837—1840. This species is also met with in Corfu in 
the dry snags of fig-trees during winter. 
Miss E. A. Ormerod exhibited some galls found on Tanacetum vulgare, 
and stated that Mr. Fitch had obtained some of a similar kind last year 
near Maldon, Essex; but the present specimens were peculiar from the 
gall-growths being not only in the axils of the leaves, but also on the midribs 
and pinne and on the inflorescence. The galls on the leaves are smaller than 
the others and solitary; those into which the axillary growth of shoots has 
merged itself are for the most part confluent, forming bunches of as many 
as seven solid bell-shaped galls grown together at the sides, or sometimes 
completely surrounding the main stem. In the inflorescence also as many 
as six or seven galls may be found on the receptacle of the composite flower, 
these being generally single, but occasionally confluent, and frequently 
bearing one or more florets on the side of the gall. The galls vary much 
in size, those on the leaves being only about three-sixteenths of an inch
