i^S CONNECTICUT EXPERIMENT STATION REPORT, I907-I908. 



dopteryx ephemeraeformis Steph. is an entirely different insect 

 and is much more common in the southern states than here. 

 Nevertheless it occurs here and is occasionally found feeding 

 upon arbor vitae in the shore towns. Specimens of larvae with 

 their bags of cases attached to fence posts were received from 

 Cheshire. 



The Rabbit Bot-fly. In September we received from South- 

 port, large larvae which had been found under the skin of a 

 rabbit below the neck. Though not familiar with this parasite 

 I consulted Professor Osborn's paper on "Insects Infesting 

 Domestic Animals" * and found that the larvae agreed with the 

 description and figures of the rabbit bot-fly, Cuterebra cuniculi 

 Clark.
