128 THE ENTOMOLOGIST. 



these readings ave at different times. Still these, together with 

 a brief description of the day and night weather, and the varying 

 results, have been duly tabulated, and may be of some interest. 

 It will be seen that our best takes (June 27th and 29th) were with 

 a north-east wind, a cloudy sky, and a night temperature of not 

 less than 56° F. In explanation of the words "good " and " bad," 

 it should be stated that they refer to the gross number of insects 

 attracted, and not to their rarity (see p. 130). 



As our captures included such species as Hadena atripUcis, 

 Dicycla oo and its var. renago, Toxocampa pastinum, Acidalia 

 ruhiginata {ruhricata), &c., a few remarks on these and other 

 species may be worth recording. 



Cymatophora octogesima. — Three examples came to sugar on three 

 separate nights. One was boxed at 1.10 a.m. on the 22ud, when but 

 six insects altogether were seen at treacle. 



C. or. — This occurred sparingly during our visit. 



C. duplaris. — Two worn specimens on July 2nd. 



Acromjcta leporina. — Our first capture came at midnight on June 

 20th, and settled on the glass front of our forty-candle power acetylene 

 lamp ! Two were taken at sugar about 9.15 p.m. Two are of the 

 ordinary light form ; the third is dusted with dark grey. 



A. ligustri. — We took four. Two are the dark " var. coronula." 



Xylophasia siiblnstris and A', hepaiica. — These two species were fairly 

 common, particularly the first named. 



X. vionogliipha. — Three very dark — and one absolutely black — speci- 

 mens were obtained. 



Neuria reticulata. — This came to light and sugar ; about twelve 

 in all. 



Apamca gemina. — This insect came next in point of numbers to 

 A. exclamationis. About one in ten was the var. remissa. 



A. unanimis. — Occurred sparingly. 



Agrotis exclamationis. — This occurred in tens of thousands, as noted 

 above. We secured some nice varieties — practically every one figured 

 in Barrett — but still, considering the numbers, the insect varied won- 

 derfully little. 



A. obscura {ravida). — Three perfect examples were secured at sugar 

 on July 2nd, 3rd, and 4th. 



Dicycla oo. — This first came to sugar on July 3rd. Four males and 

 one female. Next day (our last) we sugared an immense area, and 

 only obtained eight. One of these was the var. renago. [On July 11th 

 five worn specimens were taken by Mr. R. Brooke, and three ditto on 

 the 17th by Mr. T. P. Gardner. On the 19th they appeared to be 

 over.] This erratic species appears to be maintaining its reputation. 

 The numbers taken from this locality, according to our present know- 

 ledge, are roughly : — 1902, two hundred (Entom. xxxvi. 14) ; 1903, 

 twenty ; 1904, one (Entom. xxxvh. 214) ; 1905, twenty-one. This is 

 the only Noctua captured which is not in ' The Fenland ' list. It surely 

 must have been very much scarcer formerly to have escaped the notice 

 of even the late Mr. F. Bond. Is it not a fact that the var. renago 

 is mainly, if not entirely, confined to be counties of Northampton 

 and Hunts ? '
