[June-August 
with an entrance tunnel ten feet long. Thirty female bees were 
found hibernating in the earth near the mouth of the tunnel. 
At the November meeting Prof. C. T. Brues read a paper on 
the triungulin larva of a meloid beetle from the Galapagos 
Islands. The peculiar mandibles were described which are 
modified for holding to the hairs of bees on which the larvae 
are carried to the nest where they become parasites of the 
bee larvae. The paper concluded with a review of the triungulins 
of Meloidae and Stylops. 
Prof. W. M. Wheeler followed with a paper on the planidium 
larvae of various Hymenoptera and Diptera. Some brilliantly 
colored Chalcids were found in ant’s nests where they grew up 
as parasites in the ant larvae, having been brought into the nest 
in the planidium stage attached to adult ants. The complicated 
life histories of several species were described. 
Mr. C. W. Johnson spoke of the European Muscina pas- 
cuorum which was so surprisingly abundant in the autumn of 
1922. This year only a few were found in the fall and spring 
in Attleboro, Brookline, Walpole and Worcester. Specimens 
had been found in the fall and spring under loose bark indicating 
that the insects hibernate as adults in such places. 
Dr. Jos. Bequaert reported an article in the Annals of the 
Natal Museum, So. Africa, October 1923 on the eating of small 
fishes by a spider of the genus Thalassius allied to our Salonedes. 
The paper is illustrated with photographs, one of which shows 
a spider in the act of catching a fish near the surface of the water. 
Dr. Bequaert described a nest of wasps from Panama in 
which the paper cells were closed, not as usual by convex caps but 
by flat covers a little inside the mouth of the cell. 
At the December meeting Prof. C. T. Brues gave an account 
of his last summer’s automobile excursion from Boston to Yellow- 
stone Park accompanied by Mrs. Brues and their son and daugh- 
ter. A tent was carried and they camped at night throughout 
the trip. Their route was through Massachusetts, New York 
and Ohio to Chicago, thence to St. Paul, Minn., and the Bad 
Lands of North Dakota. At the Yellowstone Park they met 
Prof. A. L. Melander from the Washington State College and
