1088 Insects. 



the wind, should there be any, it is best to put the mixture on the side which is so ex- 

 posed, as the scent is thus carried further. Should the wind be rather high, some 

 should also be placed on the opposite side of the trees, as when once attracted to the 

 spot, moths will more readily settle on the sheltered side. Instead of putting the su- 

 gar on in stripes, I find the better way is, if the tree is not very large in circumference, 

 to lay it on thickly in a circle round the tree, it then runs down in narrow lines, and 

 is thus more conveniently sipped by the greedy moths. Should the tree be of very con- 

 siderable bulk, it can easily be laid on in the same manner on portions of the tree. I 

 met with the greatest success in a small wood, where I sugared about a dozen oak 

 trees. On the 4th of July, I took there specimens of twenty-one different species of 

 moths, among which were the following. Thyatira Batis (twelve specimens), Thyatira 

 derasa, Polia herbida, Mamestra Persicariae, Apatela Bradyporina, Acronycta Ligus- 

 tri, Xylophasia characterea and Polia bimaculosa. About a week after, I took eleven 

 more specimens of Thyatira Batis, and several other kinds different from those taken 

 on the 4th. I have not yet been able to find the names of many, having no illustrated 

 work on the subject. — J. Pemberton Bartlett. 



Flowers and Shrubs most attractive to Lepidopterous Insects. As none of your abler 

 correspondents have replied to Mr. Hepburn's enquiries (Zool. 482 and 946), respect- 

 ing the flowers and shrubs most frequented by the nocturnal Lepidoptera; I beg to 

 offer a few remarks on those from which I have met with the greatest success, and 

 shall mention first, — 



The Honeysuckle, the attractive properties of which are well known ; in the neigh- 

 bourhood of Ely, where Deilephila Elpenor and Porcellus are more plentiful than they 

 are here, I have taken several specimens of each from this plant, with a few of Sphinx 

 Ligustri, Cucullia umbratica (in abundance), Plusia Iota and Chrysitis: but at Bal- 

 lingdon it seems of little use ; I have had a fine plant in bloom for the last two months, 

 but have only taken from it one specimen of Sphinx Ligustri, one of Cucullia umbra- 

 tica and Mamestra Brassicae. 



The Jasmine is a great favourite with Macroglossa stellatarum, which I have se- 

 veral times seen eagerly enjoying its sweets, both in the middle of the day, when the 

 sun was shining very hot on the plant, and also in the dusk of evening. 



The Valerian is a very attractive flower ; among others I have taken from it Deile- 

 phila Porcellus, iEgeria Tipuliformis, M. M utilise form is, Mamestra oleracea, Plusia 

 Iota, Gamma and Chrysitis and Polia dysodea; with the last it is an especial favorite. 



The Sweet William, Larkspur and Candy-tuft are also visited by most of the spe- 

 cies mentioned above, but are not so attractive as the Valerian. 



Amongst the wild flowers I have found, like Mr. Hepburn, the bladder campion 

 (Silcne infiata) the most attractive. I have taken from it two specimens of Deilephila 

 Porcellus, and amongst the Noctuidse may be mentioned Agrotis segetum, Graphi- 

 phora triangulum, Hadena ochracea, H. capsincola, Xylina putris, Polia advena, &c, 

 and Xerene adustata, Eupithecia venosata and Emmelesia decolorata, many of which 

 swarm round it. 



The Ivy and Sallow being well known, and as your valuable periodical has already 

 recorded several captures from them, I shall pass them and conclude with 



The Reed, which appears to be less known, but which is a great favourite with the 

 autumnal moths. From the blossoms of some reeds growing by the side of a small 

 plantation near Ely, I captured on the 10th and 21st of October, 1831), specimens of 

 Orthosia Loti, O. macilentn, Ghea subnigra, Miselia Oxyacanllne, Nonagria crassicor-
