instead of laterally. Mr. Caudell considered it very closely 

 related to the Forficulidae, the males having forcipated and 

 toothed anal appendages and there being other points possessed 

 in common with the earwigs. It looks very much like a wing 

 less Embiid (Embia iihrichi wSaussure) from Trinidad.* The 

 systematic position of this insect was further discussed by Messrs. 

 Cook, Howard, and Hunter. 



Dr. Stiles, referring to a disease which has of late proven 

 so fatal to horses in the Philippine Islands, said that it is known 

 as Surra and is closely allied to the tsetse-fly disease of South 

 Africa ; it seems to be spread by flies of the genus '/ abauus' 

 The disease originated in India where Tabanus tropicus was the 

 supposed transmitter. Unlike the malarial parasite, which goes 

 through a double life-cycle, a sexual in the mosquito and a non- 

 sexual in man, Trypanosoma, the parasite of Surra, has only a 

 non-sexual generation so far as is known. This being the case, 

 the disease may probably be carried by any biting or piercing 

 insect. 



Dr. Howard said, in discussing Dr. Stiles' note, that the con 

 ditions governing the spread of this disease pointed as well to 

 some biting Muscid allied to the tsetse-fly as to one of the 

 Tabanids, since both are dependent for successful breeding on 

 moisture conditions. The biting Muscids breed most success 

 fully in moist manure and the Tabanids in damp soil muck, 

 while the Surra is well known to be most prevalent in damp 

 localities and during damp seasons. He agreed with Dr. Stiles 

 that the disease is probably carried by either of these types of 

 biting flies. 



Mr. Morris read extracts from a letter from Mr. Pollard, 

 written from Baracoa, Cuba, where the latter, in company with 

 Dr. Edward Palmer and Mr. William Palmer, was making a 

 collection of plants and zoological specimens. 



The first paper was by Mr. Caudell and was entitled : 



SOME INSECTS FROM THESUMMIT OF PIKE'S PEAK, FOUND 



ON SNOW.

No tourist visiting the Rocky Mountain region for the first time 

 thinks of leaving without ascending Pike's Peak, that most acces
