CochyliS. By F. Charmeux (he Jardin, vol. xxi. No. 493, p. 268 ; 

 2 figs.). — One of the most redoubtable pests in French vineyards is the 

 cochylis, a minute nocturnal moth, yellow in colour, with black bars on 

 the wings. The caterpillar, 8 mm. in length, is a dull purple or 

 brown with dark-red head. This insect produces two generations a 

 year ; the first in the flowering season destroys the stamens and ovaries 

 by smothering clusters and leaves in its silky threads ; the second in 

 August attacks the grapes, piercing every berry and causing them to rot. 

 It is possible to destroy the insects in both generations, but a more 

 efficacious remedy is to pick off the cocoons in October or November, 

 burning all infected wood. It is to be noted that these insect pests 

 increase in proportion as the insectivorous birds are destroyed. — F. A. W. 



Codlin Moth Investigations in 1903 and 1904. By Fabian 

 Garcia (U.S.A. Dep. Agr. New Mexico, Bull. 65; May 1907).— A 

 brief outline of the life-history and appearance of this pest is given. 

 The question as to the number of broods and the influence of the 

 weather upon this point has been investigated, and the result is here 

 recorded. The caterpillars were caught in haybands after they left the 

 apples, and these bands . were daily examined. The conclusion is that 

 the first brood of larvae matures about the end of May, the second about 

 the end of July, and the third (often a partial brood) about the second 

 week in September. The weather appears to have very little effect upon 

 the time of appearance of the larvae. — F. J. C. 



Coelogyne cristata. By C. Sprenger (Bull. B. Soc. Tosc. On. 7, 

 1907, p. 188). — According to Bentham and Hooker, Coelogyne belongs 

 to the sub-genus Epidendrum. Ninety-seven good species are known, 

 which occur exclusively in the Old World. They are all perennial and 

 epiphytes, living on trees and shrubs, amongst ferns, on lichen-covered 

 rocks, and along the sides of streams ; occasionally they are semi- 

 epiphytic. In the Himalayas they grow as far up the mountains as 

 10,000 feet, and more. Hooker says of them : " Herbae epiphyticae, 

 caespitosae vel longe repentes." He also says, which is interesting to 

 cultivators : " Flores majusculi vel speciosi, in pedunculo vel scapo 

 solitarii, vel plures laxe racemosi." C. cristata Lindl. occurs up to 

 10,000 feet on the Himalayas on old trees, such as Laurineae, Querctts, 

 or Conifers, amongst epiphytic ferns, humus and lichens, and sometimes 

 close to the ground. It is one of the easiest plants to grow. — IF. C. W.
