OnSKRVEI> IN WEST HERTS. 187 



Calligcnia miru'ata. — The rosj^ footman or red arches. — This 

 insect is ix-corded as having been taken at Haileybury, and in 1888 

 at Hertford. In 1899 it was abuntlaut in liricket Wood. From 

 July 13th to the end of the month we took it at sugar every night 

 that we went to the wood, and it remained in good condition to 

 the last. 



Lithosia hcrideola (complanuia) also occurred at sugar in Bricket 

 Wood. It has not been previously recorded as taken there. 



Stauropus fa(]i. — The lobster-moth. — On the evening of Gth July, 

 1899, a beautiful fresh specimen of this moth flew into my room, 

 attracted by the light, and tlic following night another came to the 

 window, which happened to be shut, and before I could open it 

 the moth flew away, but not before I had seen clearly what it was. 

 This insect has been recorded by Mr. Bowyer from Haileybury, 

 but is, I think, new to this side of the County. 



Noiodonta chaonia. — I took one of these moths at the electi'ic 

 light at Bushey on 23rd May, 1898. 



Lopliopteryx camelma. — Both at Watford and Bushey Heath at 

 light. 



Pterostoma palpina. — At Watford at light. 



NOCTU^. 



I give a list of these in their proper order, omitting only the 

 very common species which are taken always and everywhere, 

 and I have added a note where one seems to be required. 



In 1897 and 1898 "sugaring" — the best means, as a rule, 

 of catching this group of moths— was quite useless during the 

 summer, but the sweets became atti'active in the autumn. In 

 1899 the reverse was the case ; the summer Noctuse came to sugar 

 in numbers, but in the autumn hardly any came. The sallow 

 bloom was a failure- in the spring of 1899. 



^^^lere the name of a species only is given, without locality, it 

 has been taken at Bricket Wood, "Watford, and Bushey Heath in 

 one or other of the three years included in this paper.
