" Six forma of this are described in the book. 



1. With narrow orange patch crossed by black nerviires, ab. 

 restricta-Uneata, n.ab. 



2. With broad orange patch crossed by black nervures, ab. lata- 

 lineata, n.ab. 



3. With narrow orange patch not crossed by black nervures, ab. 

 restricta, n.ab. 



4. With broad orange patch not crossed by black nervures, ab. 

 lata, n.ab. 



5. The orange markings yellowish in colour, ab. fisoni (Wheeler). 



6. With sub-marginal series of interneural orange streaks in hind- 

 wings pointing towards base, ab. cuneata, n.ab. 



" These forms, or something approaching them, are shown in my 

 box. There is also another specimen which I cannot place under 

 any of the above names, and which I think may be a rare if not a 

 unique variety. It has almost a complete orange border to all 

 wings and much orange suffusion. 



'' Pachygastria trifoli i.— Tntt divides the forms of this insect that 

 are found in Britain into five groups, depending on ground colour. 



1. Ground colour pale yellow, ab. flava. 



2. ,, ,, yellow-grey or buff, ab. medicaginis. 



3. ,, „ fawn-grey or reddish-grey, ab. ce>-ijma. 



4. ,, ,, reddish-brown, trifolii (Esp.). 



5. ,, ,, deep foxy red -brown, ab. rufa. 



" On looking over a number of specimens this division appears to 

 be fully justified. The further sub-divisions are less numerous in 

 some cases than in others, but there is little doubt that specimens 

 could be found in each division, if the insect were sufficiently abun- 

 dant, which would show — 



(a) All the wings unicolorous and without markings (except pre- 

 sumably the white spot). 



{b) The forewings with two transverse lines, including a more or 

 less defined median band. 



(c) The median band in forewings more or less contracted. 



{(1) Ill-defined transverse lines, but well marked longitudinal 

 nervures. 



(e) The basal line obsolete. 



" It would be a good collection that exhibited all these sub- 

 divisions of each shade of ground colour. Myown falls sadly short 

 of it, and even Tutt's division fails to give many of them, perhaps 

 some of them have not yet been observed. It is not necessary to 

 trouble you further with named aberrations or those for which
