 American Entomological Society, which refers to material (Odonata) col- 

 lected by the U. S. Eclipse Expedition to the Congo and by Dr. W. L. 

 Abbott at Zanzibar and in the Kalimanjaro region. Inasmuch as the paper, 

 in its entirety presented to the U. S. National Museum for publication, 

 would be long in coming out he had, by permission from Dr. Riley, pre- 

 sented an abstract to night. Mr. Calvert reviewed the contents of the 

 paper and made drawings on the black-board to illustrate points in the 

 neuration of the old world genus Orthetrum. The characters of some of 

 the species were dwelt on at length. Mr. Calvert also exhibited a speci-

ENTOMOLOGICAL SOCIETY OF WASHINGTON. The seventy-ninth reg- 

 ular meeting was held March 3, 1892, at the residence of Mr. E. A. 

 Schwarz. Mr. Wm. Ross Harris, of Texas, 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, stigma, excretory organs and glands of the head. 

 Discussed 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, "Class, of Animals from Embry. 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 distri- 

 bution of fossil insects. This showed that the Orthopteroid, Neuropteroid, 

 Hemipteroid and Coleopteroid insects were not only the insects of the 

 PaUeozoic, but also the prevailing insect types of the Mesozoic age. The 

 I >iptera, Lepidoptera and Hymenoptera, which have a larva or caterpillar 

 stage, were later developments. Discussed by Messrs. . \shmead, Banks 

 and Gill. NATHAN HANKS, A'< ,;-<//;/<,' St-cirtary.
