 Eiker mounts for this purpose. 

 Contributions to our Knowledge of the Host Rela- 

 tions of Ticks: W. A. Hookeb. 



Discussion by Messrs. Skinner, Cooley, Viereck, 

 Bruner and Miss Mitchell. 



At 3 P.M. a joint session with Section 1*' of the 

 American Association for the Advancement of 

 Science was held in the Eastern High School. 

 Dr. J. B. Smith presided over the meeting. The 

 following papers were read: 

 Investigations of Toxoptera graminum and its 



Parasites: Mr. F. M. Webster. 



This paper was published in Science, February 

 12, 1909, p. 278. 



Discussion by Professor Washburn and Mr. 

 Hayhurst. 

 On the Muscular System of Spiders' Legs: A. 



Petbunkevitoh. 



A Note on the Habits of the Wall-bee, Chalico- 



doma muraria: J. N. Comstock. 



This insect is very abundant at Dendera, Egypt, 

 where it is covering the walls of the ancient 

 temple, that have been unearthed, with its cement- 

 hke nests, rendering it impossible to read the 

 inscriptions upon them. 



Evolution and Adaptation in the Palpi of Male 



Spiders: J. A. Nelson. 



To be published in full in the Annals. Discus- 

 sion by Drs. Hopkins and Petrunkevitch.

Adjournment. 



At 10 a.m. on December 31, the meeting was

 papers read: 



Death-feigning by Zaitha fluminea : H. P. Sevebin. 



Bead by Professor Osborn. 

 Some Habits of Seed-infesting Chalcis Flies: C. 



R. Cbosbt. 

 The Development of the Scent-pockets of Anosia: 



W. A. Riley. 



The pupal development of the scent-pocket or, 

 as it is proposed to designate it, the murotheca, 

 of the male Monarch butterfly was discussed. Its 

 future position is indicated in the earliest pupa 

 by the richness of the supply of tracheoles, indica- 

 tive of the greater physiological activity in this 

 region. Before pigmentation is apparent in the 

 rest of the wing the murotheca stands out as a 

 densely pigmented black disk overlapping vein 

 Cu,. Sections show that the androconia originate 

 on the free surface of the upper wing membrane, 

 which pushes out over the vein and later in pupal 

 life folds on itself, giving rise to the pocket-like 

 murotheca with its opening directed caudad. The 

 structure of the androconal glands was briefly 

 discussed. 



The Tracheal Supply in the Central Nervous Sys- 

 tem of the Larva of Corydalis: William A. 

 Hilton, Cornell University. 

 There are three pairs of tracheal branches going 

 to the brain and two to the subesophageal gan- 

 glion. The first thoracic has one pair and a 

 median tracheal branch. All the other ganglia 

 have one pair except the last or eighth abdominal.
