improbable that Mr. Samouelle means that it is then to be found externally to 

 the tree. It was in December that Mr. Bree found imagoes along with larvas, 

 in the decayed wood of the interior of an ash tree. On the authority of 

 Marsham, the species inhabits the wood of ash, willow, and elm. It is stated 

 in Kirby and Spence's Introduction to Entomology, of this species in the 

 imago state, that it *' will bear almost any weight that passes over it upon the 

 ground ; the head and trunk forming a slight angle with the abdomen." 



Sinodendrum cylindricum. 



Egg. Information remains to be acquired. 



Larva. There is some information in the " Facts" &c., above. 



Pupa. It [.seems from the " Facts^^ &c., above, that the pupa is not oc- 

 current in December. 



Imago. (Jig- 78.; a, female; b, male.) Information is in the " Facts," &c., 

 above : the following is additional : — Some description of the imago's person. 



— Cylindric, black, shining, impressed-punctate, cicatriculose ; the punc- 

 tures umbilicated; the umbilici perforated. The male with a conic-compressed 

 horn on the head ; the female with a short one. Antennae with a lamellated 

 club, that is not capable of being folded ; the lamellae very short, resembling 

 the teeth of a saw. Maxillae coriaceous, bilobate. (Samouelle's Entomolo- 

 gist's Useful Compendium.^ 



The haunts and topography of it. It " inhabits old trees, especially the 

 ash. It is very abundant near Cheltenham and Plymouth." {Id.) 



Mr. Rivers has noticed (p. 461.) that the Wasp and the Hornet 

 delight to feed upon the Sap of Pear Trees. It is a kindred Fact 

 that the extravasated Sap of dying Elm Trees is,, when to be 

 found, appropriated by Insects as Food : thus supplying One of 

 countless Instances of the Truth of the Sentiment that, in Nature, 

 not Anything is wasted. In the Magazirie of Natural History, 

 vol. vii. p. 525 — 530., is an account of flies, hornets, and wasps, 

 as observed feeding upon the extravasated sap of some elm trees. 

 Before the instances given there, of the appropriation, by in- 

 sects, of the extravasating sap of elms, were published, I re- 

 ceived, on Sept. 20. 1834, a notice of another instance of it; 

 this : — The elm tree which has had the branch of another elm 

 tree naturally inarched upon it, has been, this year, a very in- 

 teresting object to us, by butterflies, hornets, wasps, and green 

 flies feeding on the sap by day ; and different moths by night.

Art. VII. A Series of Designs for laying out Suburban Gardens 

 and Grounds, from One Perch to several Acres in Extent. By Mr. 

 T. RuTGER. Design 11. For laying out a Place of Half an Acre 

 in. Extent. Design 12. For laying out a Place containing Three 

 Quarters of an Acre. 



This design {Jg. 79.)? No. 11. of the series, encloses half an 

 acre. The stable is placed on the right, with a way to it from 

 the main road. The shaded part at the south of the house is 

 intended for a veranda. A small pond for gold and silver fishes
