C. dotata [jjyraliata), C. associata [dotata), Eubolia limitata {niensuraria), 

 E. phimharia (palumbarla), E. bipunctaria. — About 130 species. The 

 season of 1890 has not been a good one for light. There have been very 

 few favourable nights, and it has only been by the use of two traps, and 

 their being almost constantly at work, that I have obtained so many 

 species by means of the attraction of light. As it may be of interest, I 

 append particulars, meteorological and otherwise, of three of the best 

 nights this year. May 20th. — Warm, several violent squalls, with drench- 

 ing rain, during the night : — E. dolabraria, 1 ; M. montanata, 1 ; A. remu- 

 tata, 2 ; T. crepuscularia, 4 ; E. lariciata ; N. trepida, 2 ; L. camelina, 1 ; 



D. pudibunda, 6 ; D. coryli, 1 ; E. vulgata, 1. June 7th. — Minimum 

 during night 40°, windy ; the trap was placed in a narrow wood-ride, to be 

 protected from the wind : — H. velleda, 1 ; L. camelina, 1 ; 8. lubricipeda, 

 several ; 8. mentliastri, several ; H. tenehrosa, 1 ; H. adtista, 1 ; C. biden- 

 tata, 2 ; N. pidverarla, I ; L. viridaria [pectinitaria), 3 or 4 ; JS. lariciata, 1 ; 



E. vidgata; E. plumbeolata ; M. montanata, abundantly ; M. fluctuata, 2 : 

 C. truncata {russata), 1. July 2nd. — Warm; at 11.30 p.m. the 

 thermometer stood at 57°; W.N.W. wind; moon full, but well obscured 

 by clouds : — 8. lubricipeda and 8. menthastri, as usual ; R. tenebrosa, 1 ; 

 N. f estiva, 1 ; F. moneta, 1 ; M. margaritaria, 5 ; G. papilionaria, 1 ; 

 C. exanthemaria, 1 ; P. tersata, 2 ; T .amataria, 1 ; A. imitaria, 1. —

Fraudulent Colour-varieties. — I think that it is incumbent on me 

 to utter a note of warning on this subject to collectors. We all know that 

 occasionally " varieties " are manufactured and passed off upon the unwary 

 as being genuine examples ; and some time since an imposture of this sort 

 was detected, and described in the ' Entomologist.' In that case, however, 

 as also, I believe, in many others, the fraud was perpetrated by means of 

 painting, and was, therefore, pretty easy of detection. Now, however, anyone 

 who cares to take a hint from my experiments may manufacture the most 

 excellent varieties, and without fear of detection. I would undertake to 

 produce, myself, yellow varieties of normally red species, milk-white speci- 

 mens of P. phlceas, " sea-bleached " varieties of the heath butterflies, and 

 60 on, that would, I think, defy detection as artificial, and would very safely 

 be passed off as genuine varieties. Since, then, I feel that I have thus 

 opened a door to the unscrupulous, it is only right that I should fairly warn 

 the readers of the * Entomologist' against the chances of such deception. 

 I would strongly recommend collectors, therefore, to buy no varieties 

 similar to those artificial ones that I have described in the tables on pages 

 248—251, &c., of the last volume, and neither even to accept them- in 

 exchange, unless from correspondents whose good faith is already known to 

 them. If, after this warning, any enthusiastic variety-hunter is cheated by 

 imitators of my experiments, I shall feel that I have washed my hands of 

 responsibihty. — F. H. Perry Coste; Eavenshoe, Burnt Ash, Hill, S.E.,

The Distinguishing Marks between T^eniocampa opima, T. popu- 

 LETi, AND VARIETIES OF T, iNCERTA. — Will any readers of the ' Entomologist ' 

 kindly inform me of the definite difference in the markings of the above 

 insects? I have read Newman and Stainton closely on all three insects;
