may therefore be considered rare. Dr. Skinner exhibited a living 

 tick, Ornithodorus megnini Duges. It had been for several 

 months in the ear of a man who lived in Fremont Co., Idaho, 

 for several months. It emerged from the ear on Sept. 15, 1 902 . * 

 The specimen was kindl}^ identified by Mr. Nathan Banks, who 

 wrote as follows: "It occurs in Mexico and the Southwest. 

 I have seen specimens from as far north as Nebraska ; I guess 

 this is about the same region. It occurs in the ears of horses, 

 cattle, etc., and sometimes in man. It is usually in the ear in 

 the nymphal condition. They can usually be dislodged by the 

 use of a little oil." The specimen was received wrapped in a 

 paper and has since been kept in a pill box. The specimen is 

 therefore nearly a year old, and still hale and hearty. 



Mr. Laurent exhibited a specimen of Tramea Carolina taken 

 April 15th, in Fairmount Park, by Horace Ebert. The pre- 

 vious earliest record was May 26th (Calvert). Dr. Skinner 

 exhibited the larva of Arzama mela^iopyga Grote, which feeds 

 on the bonnet-plant in Florida. These larvae attract black- 

 birds in great numbers, the birds pulling them from the stalks 

 of the plants. 



Mr. Rehn exhibited some roaches covering the old and new 

 worlds. Edobius, new to New Zealand, was shown. Also 

 some new species from the West Indies. Colocampra, n. sp. 

 from Cuba, and a new sp. of Epilafnpra from South America. 

 The difference between some of these genera were pointed out. 

 Dr. Calvert spoke on the formation of local races in the dragon- 

 flies. Ainphigrio7i saiicium was mentioned. Those from Da- 

 kota and westward are hairier than those from further east. 

 Ischmira dcnticollis ranges from southern California and Arizona 

 to southern Mexico Those from Southern California and 

 Arizona have fewer cross-veins on the second half of the fore- 

 wings than those from farther South. Calopteryx csquabalis, 

 from the east, has a race known as yakima from the west. 

 The latter has the dark color on the tip of the wing of greater 

 extent. Variations in size in a single species was shown in 

 specimens of Megaloprepus cceurulaUis from Panama.
