The Triphaense are all characterized by their beautiful yellow 

 under-wings, bearing a black submarginal band. The Cater- 

 pillars feed only in the night, and conceal themselves during 

 the day at the roots of the plants on which they feed. It is 

 probable that they live through the winter, for I once saw a 

 considerable number, belonging I think to this genus, beneath 

 the ice which covered some meadows that were under water. 

 The following are British species : 



1. T. consequa Hiib. Curtis' s Brit. Ent. 348. — subsequa Hub. 



23. 106. var.? 

 That my specimen is distinct from our other species, there 

 is no doubt, for the superior wings are formed more like those 

 of Cerigo texta, the stigmata are larger than in T. o?-boJia, the 

 fascia of the inferior wings is broader, and the superior margin 

 beneath is black and not rosy : in colour it most resembles the 

 N. consequa of Hiibner ; his N. subsequa is more like N. orbona. 

 On the 27th July 1825, two flew out of the heath that covers 

 the hills at the back of Mr. Kean's house in the Isle of Bute, 

 one of which I captured. It is probable that the third stigma 

 is accidental, for the specimen is rubbed. 



2. T. orbona Fab. Don. 10. 343. 2.— Corner Hiib. Och. 

 Common, from the end of June to the beginning of July, in 



gardens. The Caterpillar feeds on the Plantago lanccolata. 



3. T. Pronuba Linn. Doji. 9. 311. — innuba Och. var. 



Very common, from the beginning of June to the middle of 

 July, in gardens, hay-fields, and hedges, flying short distances 

 when disturbed during the day. Mr. Lyell found one on 

 Mont Blanc, above the height of perpetual snow, between the 

 Cuvercle and Jardin, on the 7th of July 1818. The larva 

 feeds on the Primrose, Violet, Shepherd's -purse, and a Senecio, 

 but not I believe on the roots. 



4. T. interjecta Hiib. 23. 107.— Goda, pi. 59. 1. 



June and end of July, open parts in Birch, Darent, and 

 Coomb-woods, and in Norfolk. 



5. T. J anthina Fab. Hiib. Don. 10. 343. 1. — Domiduca Fues. 



3. 1. 16. 

 End of July and middle of August, Birch-wood, Epping- 

 forest, and Norfolk. The larva feeds on the Arum maculatum 

 and a Chick weed. 



6. T. fimbria Linn. Don. 6. 208. — Solani Fab. 



This beautiful moth was formerly very rare, but is now be- 

 come more plentiful. It frequents oaks from the end of June 

 to the middle of August. My friend, Henry Browne, Esq., 

 has found it at Hethersett, Norfolk, and I once took it in 

 Norwich ; the late Mr. Blunt used to breed it in Epping- 

 forest, and it has been captured at Carlisle by T. C. Hey- 

 sham, Esq., also at Darent and Norwood near London, in 

 Yorkshu'e, Derbyshire, and Devon. The larva^ are found in 

 the spring and autumn ; they feed on the Cynoglossum, Prim- 

 rose, Violet, and Potato, and Godart says they will attack other 

 Caterpillars, and even those of their own species. 



The plant is Primula Veris (Cowslip).
