then a broad white ring followed by a fuscous tip. The ground colour of the insects 

 varies considerably ; some have the ground colour of a much lighter orange than 

 others. I think this is more apparent than real, and due to the lighter insects being 

 worn and having lost some of their scales. Herr Snellen's description (Ent. Mo. 

 Mag., xxi, pp. 196, 197) is a first class one of ray insects, but I find in my longer 

 series one or two points worthy of notice. With regard to the pale silvery fascia 

 near the base, twelve out of the twenty-three just captured have the fascia broken 

 (as have others captured previously), and in six specimens the fascia is not continued 

 beyond the break, extending only about one-third across the wing. The small spot 

 on the inner margin is often absent, the caudal hook is as Herr Snellen says, very 

 variable in position ; in two of mine it is quite absent. The streak on the hind 

 margin extends to the anal angle, and is much brighter in the female than in the 

 males. I have one specimen perfectly unicolorous, with the exception of what Herr 

 Snellen ealls the fifth streak (on the costa). In fact, the size, number, position and 

 shape of the spots is very inconstant. 



There is a great deal of difference too in size. Some appear almost twice as 

 large as others, those that have partially lost their fringes look very stumpy, but fine 

 ones are sometimes very small. 



It is certain that I have only one species, and that ray species contains, I believe, 

 undoubted specimens of Leewwenhoekella and Latreillella, and probably nodosella. 

 Some of the finest specimens in my series are without doubt the former, and unless 

 this species sometimes has males with dark antennae, those with dark antennae must 

 be the so-called Latreillella. 



I have hardly ground for positively stating that I have anything referable to 

 nodosella in my series, as I have not quite a distinct idea of the ehai-acter of the 

 thickening of the antennse which occurs in this species. The finest females cer- 

 tainly have a slight thickening, and it must be remembered that all my insects were 

 active when I captured them. 



At any rate, I incline to Herr Snellen's opinion, so far as our own two species 

 are concerned. Mr. Stainton's summary of Herr Snellen's opinion (Ent. Mo. Mag., 

 xxi, 193) is that he " gets nodosella in Holland in company with Latreillella, of 

 which he thinks it is the female, and that he thinks our Leeuwenhoekella consists 

 only of worn specimens of nodosella, of which the thickening scales have vanished 

 whilst actively on the wing." 



I always take Latreillella with Leeuwenhoekella, and that there is much force in 

 what Herr Snellen says with i-egard to the absence of the thickening scales, any one 

 who has watched this active little species can readily believe. They scuttle rapidly 

 about in the grass, and are so exceedingly active that there can be little doubt they 

 soon get worn. 



Some of my female specimens of Leewwenhoekella are very fine, and, like the 

 late Professor Zeller (Ent. Mo. Mag., xxi, 193), I also have perfect specimens of the 

 female, which do not show any traces of the thickening on the antennse so charac- 

 teristic of nodosella. But although the insects niay be fine, there seems no reason 

 ■why a few scales on the antennse should not be readily worn off as soon as the insect 

 becomes active. 



I have little doubt that Herr Snellen's view will turn out correct, and I have
