Rich bfown. Antennse whitish. Head and thorax margined with white, 

 the latter with 4 white Hnes down the back also. Abdomen with a white 

 line down the middle with black spots at each articulation, and 5 large 

 black and white spots on each side. Superior wings with a broad oblique 

 ochreous fascia; nervures and an angular mark white: inferior wings rosy, 

 black at the base and a fimbria of the same colour. 



This species, which is common in North America, is said to have 

 been taken in Cornwall : some mistake may however have arisen 

 from this and the following species having been confounded. Mr. 

 Haworth has undoubtedly described the true Sphinx lineata, and 

 Mr. Donovan has figured the same species, but confessedly from a 

 foreign specimen.

Similar to the last. Antennee fuscous, whitish at the apex : the thorax has 



only 2 whitish lines on the back, each joint of the abdomen is margined 



with black, marked with 3 white spots, and there are but 3 white and 2 



black spots on each side from the base : the superior wings are also nmch 



narrower. 



The caterpillars of this rare moth feed upon Galium verum, Son- 

 chus arvensis, and occasionally upon the Vine, which great differ- 

 ence in the food may have caused the dissimilarity in the larvae 

 figured by Fuessly, since it is well known that such effects are pro- 

 duced in other Lepidoptera by the same means : they become c\\y\- 

 salides the end of July, and the moths appear 3 weeks or a month 

 after. It is very common in the South of France, but it is not 

 often found near Paris. The specimen in my own cabinet was 

 taken near Lynn in Norfolk, and Mr. Tardy has one (if it be not 

 S. lineata) that was found in a garden in Ireland. 



Esper's figure being represented without the large black and 

 white spots on each side of the abdomen at the base, is no doubt an 

 omission of the artist, which is not surprising when it is recollected 

 that Esper himself considered it only a variety of S. Celerio !

Similar to D. Euphorbias. Dark ochraceous brown. Antennee fuscous. 

 Abdomen with a line of white spots down the back and 3 on each side 

 near the apex. Superior wings with an oblique sinuated pale ochreous 

 stripe ; inferior wings pale fuscous ochre, not rosj', but red near the ab- 

 dominal margin : all the wings beneath with a brown fimbria. 



The caterpillar of this rare moth is figured by Esper ; and it is 

 probable that the larva found in marshy ground at Barns Cray near 

 Crayford in Kent, given in Harris's Aurelian, pi. 44. fig. b, was 

 the same. It feeds upon Galium verum and Molhigo, and upon 

 Rubia Ti7ictonim. The larva and moth appear at the same periods 

 as those of D. Eiiphorbice. Specimens have been taken near Pen- 

 zance, Cornwall; Kingsbridge, Devon; and in the neighbourhood 

 of London.

 states ; and although it was known to the earlier collectors, I am
