a large collection of insects from the Austral Islands recently 
brought to the Bishop Museum by Mrs. A. M. Stokes. They 
bore the label, “November 26, 1921, Rapa, Ahurei. From larvae 
on mango blossoms. Entire crop destroyed.” 
Pyralis manihotalis Guen.— Mr. Swezey reported having 
secured a specimen of this moth at his house in Kaimuki, and 
that among insects collected at Pawaa Junction by Mr. Issiki, 
entomologist from Formosa, were two of this moth. 
New Immigrant Bruchid.—Mr. Swezey exhibited a Bruchid 
which he had recently collected in a patch of cow peas at the 
United States Experiment Station, Honolulu, which is appar- 
ently different from the Bruchids at present known here. What- 
ever species it 1s has not yet been determined. 
Pheidole megacephala Fab.—Mr. Illingworth stated that on 
April 3, 1923, he had found this omnivorous ant destroying the 
parasitic wasps, Scolia manilae Ashm. Sweet potato blossoms 
on the banks of reservoir No. 6, in the Oahu Sugar Company’s 
plantation, were simply alive with these ants. They were prob- 
ably driven out of the soil by the recent heavy rains, and were 
certainly improving their opportunity by waylaying every Scolia 
wasp that visited these flowers. Many of the wasps were ob- 
served overpowered by the ants, and in various stages of being 
dismembered. It must be stated, however, that conditions at 
the time were very exceptional and probably do not occur more 
than a few days out of the year. At any rate, he stated, this was 
the first time that he had observed the ants attacking Scolia in 
such numbers. It is a well-recognized fact that the ants are more 
troublesome during the wet season, coming into houses, getting 
into bee-hives, etc., hence, they will probably let the wasps alone 
as soon as the soil becomes sufficiently dry for them to return 
LON sik: 
Pycnoscelus surinamensis (Linn.)—Mr. Hlingworth gave the 
following note on this roach: In my search for early references 
to Hawaiian entomology, I found that Eschscholtz, who was here 
in 1816, described a roach, Blatta punctata, in his Entomo- 
graphien, p. 86, published in 1822. I recently wrote Mr. Morgan 
Hebard, requesting information as to which of our present spe-
