April," while ^Ir. V. T. Chambers, Can. Ent., vol. vi, p. Tfi, says that a 

 species, which he doubtfully refers to this, was found by him in the 

 l^upal sta^e in Blue Grass pastures, and exjiresses the opinion that the 

 larvic were probably miners in the leaves of that g,rass. 



My rearing was, of course, untimely, and it is altogether probable 

 that, uiMler a natural ciivironnient, 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, 1S92. — Election of officers for 1892 resulted as folloAvs: President, C. V. 

 Riley ; first vice-president, C. L. Marlatt ; second vice-president, William H. Ashmead ; 

 treasxirer, E. A. Schwarz ; recording secretary, Nathan Banks; corresponding secre- 

 tary, L. 0. Howard; additional meni1)ers of the executive committee, William H. 

 Fox, George Marx, and B. E. Feraow. 



In the report of the Kecordiug Secretary it was shown that during the year liSiJl 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. Mars, delivered his annual address on "An Introduction 

 to a Monograph of the American Ticks (Ixodidic)." In 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, 



Eecording Secretary. 



February 4, 1892. — Messrs. D. G. Fairchild and M. B. Waite were elected active 

 members of the Society. / 



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 belouge<l to the subfamily AphelininH». 



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 thtj 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 (Enothera speciosa captures small Dii)terous insects upon its gummy style 

 and stigma. But one sjiecies was seen trapped. As the insect could not be eaten by 

 the i)lant, th« 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.
