INSECTS INJURIOUS TO THE VINE. 317 



name of Pyralis Vitana. For certain reasons, which I shall 

 presently adduce, neither of these names can be retained : in 

 order to avoid all confusion we have named this insect Pyralis 

 Danticana, after Bosc's second name — Dantic ; as we could not 

 make use of Bosc, his first name, Fabricius having already 

 appropriated it in his Pyralis Boscana. 



The second species is the Procris Ampelophaga of Duponchel, 

 Bayle, and Passerini, named P. vitis by Boisduval. 



The third is the Tortrix Roserana of Frolich, or the Cochylis 

 Roserana of Duponchel and Treitschke, Tinea Ambiguella 

 Hubn. 



The fourth is the Tortrix Heperana of Treitschke and 

 Duponchel, or Pyralis Fasciana, Fab. 



The caterpillar of Cochylis Roserana, which has been men- 

 tioned by Frolich as committing great devastation in the 

 vineyards in the neighbourhood of Stuttgard, has not been 

 described by him, nor, as I believe, by any other entomologist. 



There is then Pyralis Danticana? the Ampelophaga* of Boyle 

 and Passerini, and Fasciana, respecting the destructive effects 

 on the vine of which, there can be no doubt. Except on the 

 caterpillars of two species, we have no observations sufficiently 

 exact to enable us to determine the species. 



The caterpillar of the first of these, b P. Danticana, is, 

 according to Bosc, comprehended, in the neighbourhood of 

 Paris, in the collective term Larva?, or grubs hurtful to the 

 vines; in Burgundy, and the vine countries, it is called Ver- 

 coquin, an epithet sometimes applied to the larva of the cock- 

 chafFer (the Spondylus of Pliny). 



This caterpillar is, a short time after it leaves the egg, 

 about a third of an inch in length ; its head is black, body 

 green ; it has a yellow spot on each side of the neck. 



It is first seen in the month of May, towards the end ; the
