8 THE CANADIAN ENTOMOLOGIST 



Holotype. — <^ , Eastern Harbour, Cape Breton Island, X.S., Canada. 

 (A. G. Huntsman). 



A close ally also of Tipula entomophtlwrae^ Alex., which it resembles in 

 hypopygial structures and from which it is differentiated in the bicolored, 

 flagellar segments and the ill-defined, thoracic stripes. It differs from Tipula 

 angulata Loew and Tipula hiiron Alex.^, in the angulate fascia not rendering the 

 posterior wing- margin. Tipula texensis Alex.^, has the pale fascia before the stigma. 



Respectfully dedicated to Dr. A. G. Huntsman. 



A NEW USE FOR THE AEROPLANE. 



The Department of Agriculture at Ottawa has discovered a new use for the 

 aeroplane. The Entomological Branch is investigating the mosquito in the 

 Lower Eraser Valley in British Columbia. By using the aeroplane, the country 

 can be surveyed in order to m.ap out the swampy areas and other breeding 

 places that are readily located in photographs taken from over head, according 

 to a statement by Dr. C. Gordon Hewitt, Dom.inion Entomologist, that appears 

 in the October Agricultural Gazette. The aeroplane was used in making a 

 comprehensive survey of the complicated water system of the Eraser River and 

 the adjacent bodies of permanent and temporary water in that district. A 

 flight reported by Dr. Hewitt has demonstrated the possibility of using this 

 machine also for making surveys of timber that is being killed or has already 

 been destroyed by various insects. Its use, it is believed, will help very greatly 

 in the entomological work with various insects being carried on In- the Federal 

 Department of Agriculture. 



THE HOUSE CENTIPEDE, CERMATIA FORCEPS RAF. IN MONTREAL. 



A specimen of, this Myriapod was found in a classroom of Goltman's Busi- 

 ness College on St. Lawrence Boulevard (corner of Sherbrooke Street) on July 

 22, 1919, and was sent by Mr. Robert Goltman to me for the Redpath Museum 

 where it Avas seen by Mr. A. F. Winn. It was kept alive feeding slightly upon 

 house-flies until August 19th, when, by an unfortunate accident, it escaperl. 

 The species is mentioned in Comstock's Manual (p. 46) as "often found running 

 on the walls of houses, especially in the Southern States." It was observed in 

 Albany from 1870 onwards by J. A. Lintner, but this is believed to be the first 

 record of its occurrence in Montreal. Lintner's account of its cleaninghabits was 

 confirmed; when cleaning the hinder limbs the body is bent sideways. The 

 appendages of one side are cleaned in succession, beginning with the antenna. 



The occurrence of this Myriapod in Canada has been recorded only once 

 previously, a specimen having been taken in Toronto. (Can. Enl., XLVI, p. 



219, 1914.) A.RTIIIR WiLLEY. 



Two other specimens of the house centipede from Toronto ha\'e been 

 sent me to for determination since the record cited h\ Prof. Wi!!e>' was published.
