556 Crepuscular Lepidoptera 



all of the species of Sesia enumerated by Laspeyre and Ochsen- 

 heimer are to be found in Switzerland.) 



Sphi'nx. 



37. /uciformis. In May and June, on flowery slopes; rather common. 



38. fiombyliiformis. Similar places to the last. 



39. stellatarum. Very common everywhere in July and September. 



Late ones often winter in houses. 



40. cenotherae. Near Berne, very rarely. By Winterthur, &c, the larva 



is found in July at its full growth, and changes above ground. The 

 fly is produced the following year ; often in April, but frequently 

 not till June ; and requires several hours for the full developement 

 of its wings. 



41. nerii. I insert this species with doubt, not knowing that any indivi- 



dual has been taken wild. It is probably native to the southern 

 parts of the Tessin, as it is unquestionably found in the Borromean 

 Islands. (The breeders in the Valais, &c, rear many of them ; but 

 I have my doubts as to whence they obtain the larvae.) 



42. Celerio. Italian Switzerland; extremely rare in Northern Switzer- 



land. In 1804, a perfectly fresh specimen was taken at the Orphan 

 House, in the town of Berne ; and it has since been found at Yver- 

 don. (In 1834, one was also taken under the arcades at Berne.) 



43. Elpenor. Rather common everywhere. At Berne the larva is 



usually found on Impatiens Nolitangere. (Elsewhere on various 

 species of Epilobium ; and at Thun, very frequently in vineyards, 

 which Duponchel says it rarely inhabits.) 



44. Porcellus. (Similar places to the preceding, but much more rare.) 



45. lineata. Everywhere rare ; but has sometimes been taken near Berne. 



In the summer of 1818, it was more than usually plentiful ; and I 

 was much surprised at finding it at noon-day on Cirsium eriopho- 

 rum, on the Alp of Sollalex, at the foot of the Diablerets. 



46. galii. Rare. Near Burgdorf. I once found the larva at the foot of 



the Gemmi, near the baths of Louesch ; and the sphinx also near 

 the Bourg of Louesch, in a meadow. (In 1834, many were taken; 

 not a few near Berne.) 



47. hippophaes. This rare sphinx is found in the Lower Valais, and in 



the neighbourhood of Geneva. (Chiefly in the valley of the Arve, 

 on the road from Geneva to Chamouni, where the i/ippophae rham- 

 noides is scarcely more abundant than in the Lower Valais. This 

 plant is also extremely common about Thun; but I cannot learn 

 that the insect has ever been taken here. Godart observes, in 

 1822, that the price of this sphinx at Geneva was still ten napo- 

 leons. It remained for some time at three napoleons ; but, from 

 the numbers bred at present, good specimens are sold for three 

 francs.) [Mr. Spence has noted (in IV. 148.) thus on this species: 

 — " Sphinx (Deilephila) hippophaes, formerly sold at fifty francs 

 each, and of which one of the first discovered specimens was sold 

 for 200 francs, is now [Mr. Spence' s communication is dated Au- 

 gust 27. 1830.] so plentiful, in consequence of the numbers collected 

 and bred by the peasants all along the course of the Arve, where 

 i/ippophae rhamnoides grows in profusion, that a specimen costs 

 but three francs.] 



48. euphorbiae. In the warmer parts of Switzerland, Canton de Vaud, 



near Bex, and in Valais, &c, very common ; near Berne, rarely ; 

 near the signal on the Belpberg (between Berne and Thun), abun- 

 dant. 



49. Fespertilio. First taken near Baden, at the foot of the Lagerberg 



(Argovie), sitting on a rock: since in several other places, as at
