234 ENTOMOLOGICAL SOCIETY 
stata capitata Hentz, which consists of a pair of straight rows of 
rather long, flattened, and blunt, closely-set bristles or rods, 2$ to 
28 in number, situate at each side upon the inner surface and at 
the base of the first joints of the inferior spinnerets, closely over 
the underlying cribellum. From its structure and position, the 
speaker infers that these two peculiar comb-like organs might 
act as an accessory calamistrum. These organs have hereto- 
fore been overlooked by arachnologists, which is the more re- 
markable as they appear also in the common European species, 
Filistata testacea, as the speaker is informed by Prof. Thorell. 
JUNE 27, 1889. 
Nine persons present. President Schwarz in the chair. 
Mr. G. W. J. Angell, of New York City, was elected a corre- 
sponding member of the Society. 
In a note on May beetles, Dr. Marx stated that in the forests of 
Tuchel, near Graudenz, Prussia, comprising 16 forestry districts, 
30,000 litres of beetles (Melolontha vulgar is} had been collected 
this season in each district, or in all 480,000 litres of beetles. 
One litre will contain 450 beetles, thus making a total of 216 mil- 
lions destroyed. 
Referring to the appearance of the Periodical Cicada in the 
District of Columbia, Prof. J. B. Smith said that on June 22d 
he had heard the Cicadas singing on the old oak trees on the yth 
street road, not far from Soldiers' Home.

AN ANOMALOUS CHALCID. 
By WM. H. ASHMBAD. 
The little Chalcid, the subject of my remarks, and which I shall have the 
pleasure of showing you to-night, is not only one of the most anomalous 
of forms in the family Chalcilidce, but, on account of the peculiarity of 
the wings, one of the most remarkable insects in the order Hymenoptera. 
It was captured at large by my lamented friend Dr. R. S. Turner, at 
Fort George, Florida, and was only recently discovered among a quantity 
of unexamined material in this family that, for want of time, I have left 
unstudied. 
In nearly all of the hymenopterous families are forms that present 
marked structural peculiarities, spines or horns on the head, scutellum,
