odes, Anepsius, Eulabis, Pyrota, Dinocleus, Cleonus, Lixus, and the 
different genera of Cistelide. 
Some changes are noticeable, e. g., the genus Trogoxylon is merged 
in Lyctus and the latter removed from the Ptinidz and placed in the 
Clavicorn family Cucujide, a change which is scarcely warranted when 
the biological affinities of this genus with the Ptinide and the wide 
divergence of its earlier stages from those of the Cucujide are taken 
into consideration.—F. H. C. 
FOURTH ANNUAL MEETING OF THE ASSOCIATION OF ECONOMIC ENTO- 
MOLOGISTS. . 
COLUMBUS, OHIO, May 10, 1892. 
In accordance with an action of the Association, taken at the Washington meet- 
ing, the fourth annual meeting will be held at Rochester, N. Y., two days prior to 
the meeting of the American Association for the advancement of science. 
All members intending to present papers are requested to forward titles to the 
undersigned before August 1, in order that the program may be prepared in proper 
season. 
The proceedings of our meetings are attracting the attention of working entomolo- 
gists of other countries, and it is to be hoped that members will spare no efforts to 
make the coming meeting even better than those which have preceded it. Owing to 
the continued ill health of President Lintner, and in order to relieve him of as much 
labor as possible, all correspondence, unless of a nature necessitating his attention. 
may be addressed to the Secretary.

ENTOMOLOGICAL SOCIETY OF WASHINGTON. 
March 3, 1892.—Nineteen persons present. Mr. William Ross Harris, of Tyler, 
Tex., was elected a corresponding member of the society. Dr. Stiles gave a talk 
on the “‘ Histology of Ticks.” He made some blackboard sketches and exhibited a 
number of slides illustrating the subject. He dwelt especially on the cuticular 
tissue, alimentary canal, stigmata, excretory organs, and glands of the head. Dis- 
cussed by Dr. Marx. 
Dr. Theo. Gill presented a paper on “‘The Larva of Insects as an Intercalated 
Stage.” He quoted and criticised certain statements in Agassiz’s ‘‘ Classification of 
Animals from Embryological Data.” From these criticisms he argued to show that 
the larva of insects was an added or intercalated stage. He-had prepared a table 
giving the distribution of fossil insects. This showed that the Orthopteroid, Neu- 
ropteroid, Hemipteroid, and Coleopteroid insects were not only the insects of the 
Palzozoic, but also the prevailing insect types of the Mesozoic age. The Diptera, 
Lepidoptera, and Hymenoptera, which have a larva or caterpillar stage, were later 
developments. Discussed by Messrs. Ashmead, Banks, and Gill. 
Thursday, April 7, 1892.—Twenty-one persons present. Mr. George ‘D. Bradford, of 
New York was elected a corresponding member. The discussion of Dr. Gill’s paper 
entitled ‘‘The Larva of Insects as an Intercalated Stage,” postponed from the pre- 
ceding meeting of the Society, was taken up and participated in by Messrs. Stiles, 
Riley, Gill, and Banks. Dr. Riley presented two papers, one ‘‘On certain peculiar 
Structures of Lepidoptera” and the other, ‘‘ Descriptions of new Prodoxide.” He 
spoke of various interesting structures of the Prodoxide, calling attention more par- 
ticularly to the saw-like ovipositors, the maxillary tentacles the cenchri-like spots
