April,” while Mr. V. T. Chambers, Can. Ent., vol. VI, p. 76, says that a 
species, which he doubtfully refers to this, was found by him in the 
pupal stage in Blue Grass pastures, and expresses the opinion that the 
larvee were probably miners in the leaves of that grass. 
My rearing was, of course, untimely, and it is altogether probable 
that, under a natural environment, the imago would not have emerged 
until early spring. Therefore it seems probable that in central Ohio 
the species is two-brooded, eggs being deposited in April or early in 
May, and again in September of October.—F. M. WEBSTER. 
ENTOMOLOGICAL SOCIETY OF WASHINGTON. 
January 7, 1892.—Election of officers for 1892 resulted as follows: President, C. V. 
Riley; first vice-president, C. L. Marlatt; second vice-president, William H. Ashmead; 
treasurer, E. A. Schwarz; recording secretary, Nathan Banks; corresponding secre- 
tary, L. O. Howard; additional members of the executive committee, William H. 
Fox, George Marx, and B. E. Fernow. 
In the report of the Recording Secretary it was shown that during the year 1891 17 
new members had been added to the rolls of the society, raising the total number to 
53 persons, of which number 27 are active and 26 corresponding members. 
The retiring President, Dr. Marx, delivered his annual address on ‘‘ An Introduction 
to a Monograph of the American Ticks (Ixodidz).” Jn an introductory chapter the 
author drew attention to the absence of monographic works which would attract and 
facilitate the work of the beginners in arachnological studies, and also the inherent 
difficulties in the obscurity of many of the classificatory characters. He pointed out 
the nature and extent of the work already done in the various groups of Arachnida, 
and followed with a reference to the bibliography of the writings, both foreign and 
American, on the Ticks of this country. 
A full chapter on the morphology of the Ticks followed, and also extended notes on 
the biology of these parasites, in which personal observations were recounted, showing 
that Ticks are not necessarily parasitic on warm-blooded animals, but may reach full 
growth and in fact complete the cycle of their existence on a strictly vegetable diet; 
and also that Ticks after being gorged with blood may revert to vegetable food. The 
address was discussed by various members. 
C. L. MARLATT, 
Recording Secretary. 
February 4, 1892.—Messrs. D. G. Fairchild and M. B. Waite were elected active 
-members of the Society. f 
Under the head of short notes Mr. Ashmead made some interesting remarks on 
Eunotus, a peculiar Chalcidid genus, new to the United States. It was his opinion 
that it belonged to the subfamily Aphelinine. 
Mr. Banks exhibited a specimen of Loxosceles, which had but six developed legs. 
Dr. Marx exhibited a peculiar Theridiid spider with extremely long mandibles. 
Dr. Stiles made some instructive remarks on the liver-fluke story that was circu- 
lated in certain papers. According to this story the young stages of the liver-fluke 
were passed in the House Fly, whereas they are passed in snails. 
Mr. Mally read a paper on ‘‘An Insectivorous Primrose.” He drew attention to the 
fact that @nothera speciosa captures small Dipterous insects upon its gummy style 
and stigma. But one species was seen trapped. As the insect could not be eaten by 
the plant, the author thought that the insect must in some way aid the fertilization 
of the ovules. Discussed by Messrs. Ashmead, Test, Schwarz, Marx, Howard, 
Stiles, and Marlatt.
