Dr. Abbot and Mr. Dale have observed that the Larvae lie un- 

 der ground seven days before they change to Pupae. S. Quer- 

 ais is the only European Smerinthus that is not found in En- 

 gland. 



1. S. ocellalus Linn. — Curt. Brit. Ent. pi. 482. ? . — Don. 8, 



269.— Wood, pi. 4./ 7. 



Superior wings with the posterior margin but slightly undu- 

 lated. Rosy, variegated with brown, a chocolate oval spot on 

 the thorax ; base of the under wings fine rose colour with a 

 large black spot at the anal angle, bearing an azure ocellus. 



The Caterpillar is full grown the end of August ; it feeds 

 on the Sallow, Willow, Apple and Sloe ; also on the Peach 

 and Almond in France. The Moth appears the end of May, 

 and is distributed through the country from Northumber- 

 land to Devonshire. 



2. S. Populi L.— Don. 7. 2^\.— Wood, pi. 4./ 9. 



All the wings denticulate, especially in the male; bright 

 grey or pale cinereous, variegated with brown, superior wings 

 with a white spot on the disc, inferior brick-colour at the base. 



Caterpillar found the end of August and middle of Septem- 

 ber on Poplar, Asp and Willow : Moth the end of June, mid- 

 dle of August and rarely in September throughout England. 

 Mr. Dale has a very large and light var. from Capt. Blomer, 

 and he obsei'ved one in Mr. Leplastrier's collection which 

 had no red at the base of the under wings; it was found near 

 Dover. It is very remarkable that several hermaphrodite 

 specimens of this Moth have been discovered ; a very fine one 

 was presented to me by C. K. Sheridan, Esq., in which the 

 wings, antennae and legs on the right are male, and those on 

 the left female, as perfectly as if a male and female had been 

 divided lengthwise vertically, and the opposite halves of the 

 two sexes united ! 



3. S. Tilise L.—Dcm. 10. 325.— Wood, j^l. 4^.f. 8. 

 Superior wings deeply and irregularly excised at the pos- 

 terior margin : olive green ; thorax with a pale lobe from 

 the base towards the head : superior wings more or less rosy 

 at the disc and towards the base, with an oblique olive green 

 fascia across the middle, lobed externally and frequently di- 

 vided ; inferior wings black at the anal angle, diffused in an 

 oblique ray. 



Caterpillar middle of August on Lime and Elm-trees ; it is 

 said also to feed upon the Alder, Birch and Oak. Imago the 

 middle and end of May and occasionally in July and August. 

 Not uncommon round London and I believe wherever Lime- 

 trees are plentiful, but Mr. Dale has only taken one specimen 

 in Dorset. It is a very variable species, and the same gentle- 

 man has a curious variety with the upper wings dissimilar, 

 and there are two in the British Museum exhibiting the same 

 differences.
