194 THE ENTOMOLOGIST. 



not one N. Senex : I went the nine following evenings, but 

 not one more N. Senex could I get. Many an evening have 

 I gone out with my sugar-can, brush, lanlhorn, and a bagful 

 of chip-boxes, the weather being warm and still ; but not a 

 moth came to the sugar, I have met with this sort of luck 

 so often that I resolved, if possible, to find out what was a 

 good night to start upon : I have found that the night must 

 be dark, with slight rain and little wind : such a night is 

 sure to be good. Now take a warm, still, dry night : you 

 will see Noctuae flying about as if they were mad, but none 

 come to the sugar: this is what I call a "breeding" night. 

 For about half an hour the Noctuae will thus fly; after that 

 there is not one on the move. On these nights seai'ch the 

 herbage and trees, and you will find lots of Noctuae and 

 others in cop. Last autumn, when out on the sand-hills, the 

 wind being south and still, the Noctuae were flying in swarms 

 for a short time ; then not one is to be seen on the wing : 

 on looking among the tall grass I am sure 1 could have taken 

 fifty pairs of Xylophasia sublustris, with many others. I 

 have been for three seasons after Acidalia emutaria, an insect 

 that will only fly on a warm, still night ; but I have never 

 taken one : it is there, but will not move. Summary. — 

 Wind south or south-west, dark, light rain, slight breeze, 

 good ; but if one point to east or north, no good. North- 

 west, if any wind, no good ; if calm, a little may be done. 

 South or west, still and warm : these are breeding nights ; 

 sugar little or no good. North, with a light wind, or east, 

 little good ; with a strong wind, no good ; stay at home. 

 No time is good just before rain : often have I been out with 

 every prospect of a good night, but nothing has come : I 

 have told my friends there would be rain before morning, 

 and it has invariably come. Sultry weather just before 

 a thunder storm is good, but not after. In general, entomo- 

 logise after rain, and not before it. By attending to these 

 rules the Entomologist will not be far out. Although I have 

 been speaking of coast-collecting, these rules will hold 

 equally good with inland-collecting. — H. J. Harding ; 171,

127. Luperina cespitis at Deal. — I have taken this insect 

 on the sand-hills at Deal. It is, I believe, new to the Kentish 

 coast. — Id.
