TisckeriaanguslicoleUa^Heyd., and Solenohia triquetrella, Hubn. — I bred the above 

 additional species to our list in May last. The former makes a blotch mine in rose 

 leaves, the perfect insect resembling Gelechia tenebrosella ; the latter from cases 

 found on and under mill-stone, grit-stone, &c., on the moors. This species and its 

 habits are fully described in Bruand s ' Psy chides,' pp. 10()— 7. — R. S, Edleston ; Bow- 

 don, December 7, 1 857. 



Note on the regular Perforation of Leaves. — ^txy I venture to ask, through the 

 medium of the 'Zoologist,' if a satisfactory explanation can be given of the symme- 

 trical perforations found in the inclosed elm leaves ? Are they the work of an insect, 

 or the natural though unusual form of decay of the leaf The leaves thus perforated 

 were all found on the ground : can they be found in the same state when growing on 

 the tree? — Marie Wiry; Lentonfield, near Nottingham, November 10, 1857. [The 

 leaves are those of the wych elm, and the holes occur, with wonderful symmetry, at 

 equal distances on each side of the midrib. They are evidently the work of the larvae 

 of a sawfly, which lays its eggs on the midrib of the leaf, and the young larvae, de- 

 scending right and left, devour the leaf, each making a single hole. It is, however, 

 very difficult to account for the close similarity of size and shape observable in each 

 opposite pair of holes. Something very similar has been observed in the destructive 

 labours of the gooseberry grub, and a leaf thus perforated is very accurately figured at 

 p. 59 of the ' Letters of Eusticus.'— -E. iV.] 



Fungus on a Rhyncophorous Beetle. — Mr. Ingall has placed in my hands a speci- 

 men of Heilipus brachypterus which is in the finest condition, and looks as though it 

 had been pinned while living, yet has several specimens of a black thread-like fungus, 

 probably a Sphseria, growing from various parts of its body ; three of these, about an 

 inch in length, issue from the interstice between the prothorax and elytra ; a fourth 

 issues beneath the head, from the interstice between the head and prothorax ; and 

 there are many shorter ones in a diversity of situations ; but none appear to have 

 pierced the more solid parts of the exo'skeleton.— JEdward Newman. 



Notes concerning the capture of several interesting Species of Coleoptera. — Carabus 

 intricatus is no longer a great rarity in this country. I have given a deal of time 

 during the last three years to the working up of this insect, but until the autumn of 

 1856 had not met with living examples, having found remains only. Last autumn I 

 accidentally found a wounded but still living specimen, which gave a clew to a 

 habited locality. Having called upon a brother collector, and made known to him my 

 fortune, I proposed that we should go and try for other specimens ; accordingly, we 

 started, and on the first day obtained several examples. I worked the whole of last 

 winter and the preceding and present autumns, and find that up to the present time 

 I have captured no less than 115 living specimens. The modes of capture are various, 

 viz., by sugaring, searching among moss and loose stems of ivy upon trunks of trees, 

 and by baiting wide-mouthed bottles with dead slugs. The times of appearance are 

 early in summer and autumn, but the best time is the latter, as they are then fresh 

 from the pupa condition and still immature ; great care is necessary at this period in 

 handling them, or they harden deformed : October is the middle of the season. They 

 vary very considerably in size, as well as in intensity and shade of colouring, the size 

 varying from 10 to 15 lines in length and from 3J to 5i in breadth, and the colour of 

 some being almost black, others possessing fine tintings of green and violet. The period 

 of impregnation is the spring ; at no other time have I observed them in coition. The 

 larva of this species I have not yet met with. C. intricatus, in common with other 

 species of the genus, is supplied abundantly with a powerful acid of a caustic nature,
