]Mr. South also exhibited TriphcBiia comes, Hb., from 

 Dundee and Perth, and made the following observations on 

 the markings of the secondary wings : — 



" The central spot on under surface of secondaries is 

 generally less conspicuous than above, and often entirely 

 absent. In specimen No. i, for instance, the spot on the 

 upper surface is large and well defined, but beneath it is 

 very small. In Nos. 3 and 4 the spot is absent below, whilst 

 in No. 5 it is as large as on the underside of No. 2, but is 

 hardly visible on the upper surface. 



" Another phase in the variation of this species is illus- 

 trated by No. 5, and here again it is the ornamentation of 

 the secondaries which is aberrant. In the black band pre- 

 ceding the outer margin we have a character which is sub- 

 ject to modification in several ways, but two only of these 

 will be referred to, i.e., A. Disruption ; B. Abbreviation. 

 In No. 5 we see the band is distinctly separated at a point 

 where it is intersected by the first median nervule. In the 

 two examples above, the band exhibits a tendency to break 

 up at the same point. (The band in No. 3 is on one side 

 apparently intersected by the three median and second sub- 

 costal nervules, but this is really due to abrasion.) 



" Again, the band is usually broad towards the costa, 

 where it unites with a black or blackish costal streak ; but in 

 No. 6 we see the band is contracted beyond the first subcostal 

 nervule, and there is no costal streak for it to unite with." 



Mr. South, referring to Mr. Turner's query at the last 

 meeting as to Triphczna pronuba, L., and its var. innuba, Tr., 

 stated that in the variety the wings and thorax were 

 concolorous. 



i\Ir. J. A. Cooper exhibited a series of Deilephila galii, 

 Schiff., bred this season from larvae found in Suffolk and 

 Essex ; and stated that although he had this autumn again 

 looked for larvae, he had not been able to find any. Mr. 

 Tugwell remarked that his experience coincided with that of 

 Mr. Cooper as to the total absence of the larvse even in those 

 places where it had been abundant the previous year. 



Mr. Wellman exhibited examples of Gnophos obscuraria, 

 Hb., from Lewes. Mr. Weir having stated that this pale 

 form of the species only seemed to occur at Lewes, Mr. Tutt
