AND THEIR TRANSFORMATIONS. 107 
13. Catocalides (Catephia, Catocala, Ophiusa, &c.) 14. Noctuo-Phalenides (Euclidia, Brephos, Anthophila, 
Erastria, &c.) 
M. Guenée, who has especially studied the Noctuze of Europe, and has published a series of papers upon the 
genera of these insects in the ‘ Annales de la Société Entomologique de F rance, has in the last volume of that work 
(1841, p. 235) given a complete revision of the genera and species, which differs from that of Boisduval in 
several respects; for instance, he divides the group into eighteen tribes, arranged as follows:—J. Bom- 
bycoidi. 2. Noctuo-Bombycidi. 3, Bryophagidi. 4. Leucanidi. 5. Apamidi. 6. Noctuelidi. 7. Orthosidi. 
8. Hadenidi. 9. Xylinidi. 10. Heliothidi. 11, Plusidi, 19. Calpidi. 13. Amphipyridi. 14. Ophiusidi. 
15. Catocalidi. 16. Phalenoidi. 17. Acontidi. 18. Noctuo-Phalenidi. 
The benefits resulting from this cutting up of the group into so many minor divisions, are to be found in 
an enlarged idea of the natural relations of the different genera. My reasons for not adopting them in this 
work are, first, that such an arrangement, founded only upon insects of a certain district, without the slightest 
reference to those of other parts of the world, must necessarily be inaccurate and unnatural; and secondly, 
that it has been thought advisable in this work to follow, as far as practicable, the arrangements of recent 
English authors upon this order.

The whole of the above insects are from specimens presented to me by Mr. H. Doubleday, with the exception of C. cytherea from the British 
Museumand T. subsequa from Curtis. The Caterpillars, 12 and 13, are from Hiibner. 11 is froma living specimen. The Primula elatior is 
from a specimen sent me by Mr. H. Doubleday, from Banfield, Essex, where there are several acres nearly covered with it, and where it constantly 
preserves its drooping character, and never throws up single flowers from the base, as is frequently the case with the common Oxlip, which is 
generally considered a hybrid. Mr. Doubleday thinks the present plant may be the true Primula elatior of Linné. It is perfectly scentless— 
H.N.H. 
TRIPHAINA, OcusenHEIMeER. 
This very well marked group has the antenne simple in both sexes ;'the palpi reaching beyond the head 
and ascending; the terminal joint very short; the thorax smooth, or but very slightly crested in front; the 
abdomen broad and flattish, reaching beyond the hind wings; terminated by a brush in both sexes; the fore 
wings narrow and elongate, with the two ordinary marks distinct ; the hind wings yellow, with a broad dark 
submarginal bar. When at rest, the fore wings are carried almost flat. The caterpillars have sixteen feet, and 
are smooth, thick, cylindrical, somewhat attenuated in front, and fleshy, with the ordinary lines distinct. They 
feed exclusively on low plants or grasses, and keep themselves hidden during the day under stones. The pupze 
are smooth, shining, and cylindric-conic, and are inclosed in cocoons of earth, of a slight consistence, but at a 
considerable depth underground. The perfect insects are amongst the most powerful fliers in the order.
