" With regard to the antennje of the burnets I agree fully with 

 what Mr, Curwen says. 



" LonicercE tends to have longer and more tapering antennas than 

 trifolii, and in addition the terminal segment of lonicene is usually 

 fully extended and pigmentless (red in colour); that of trifolii 

 blunter, with a partially retracted terminal segment, which is fully 

 pigmented (black in colour). 



" My Oxford trifolii are invariably of this type, but I have seen 

 exceptions from other colonies. A Hampshire colony invariably 

 shows intermediate pigmentary characters. 



" Early and late tili/ienilulcr are usually of the lonicerte type, with 

 unpigmented tip, but intermediate and fully pigmented ones occur. 

 All the Oxiovd filipe7idi(l(c are entirely devoid of pigment. 



"In my examination of the antennae of various species I did 

 discover one interesting point. All the transalpina examined had a 

 patch of white scales on the last scaled segment or last two scaled 

 segments. This is very obvious with a lens. If it is a constant 

 character, or even a usual one, it may prove very valuable. White 

 scales are never found in British six-spotted burnets, but are very 

 conspicuous in ephialtes, which, as Mr. Curwen says, is in some 

 other respects near tiansaljiina. 



" With regard to the status of limicera; this species has a very 

 distinct facies, difficult to put into words, and is very constant. It 

 is the only species of five-spotted burnet found in Ireland. Ap- 

 parently it is much more fertile with fiiipendiihc than trifolii. 

 Pierce says that the genitalia are unlike those of trifolii, there 

 being teeth of different shape on the penis. On these grounds I 

 regard it as a separate species. 



" The early and late filipendiihc must be grouped as one species at 

 present. I consider that the differences in appearance and time of 

 emergence in different colonies are due to their isolation and 

 marked tendency to minor variation in rate of growth of larva and 

 in imaginal characters. The larvae are alike and the pupae placed 

 in the same situations. Slight differences occur in the genitalia, 

 but only in the size of the different parts, and are probably to be 

 regarded as mere variations, like those which occur in the wing 

 characters in different colonies, but my material is insufficient to 

 make me sure of this point. 



" If a new species is to be found at all I think A. trifulii-urinor 

 will supply it. 



" In addition to a marked difference in appearance ivom jxdatitris,
