240 THE entomologist's record. 



pitted cells, Avhilst at the bottom of the depression the micropyle is 

 seen in the form of a tiny, raised, conical point. An ochreous shad(> 

 in the coloration of the sides suggests that the embryo is already well 

 formed, although the larva will not, if Buckler's observation be correct, 

 hatch until next spring. Eggs described September 16th. I am 

 indebted to Mr. Hamm for the eggs. — J. W. Tutt. 



Notes on the life-history of Papilio machaon. — The ova were 

 found by Mr. F. B. Harvey, on wild carrot, at Kanworth Marshes, 

 June 2Gth, 1896. 



Descriptinn of aifi. — Half sphere in shape, dull reddish when 

 found, turned afterwards to a dark livid hue. Hatched June 30th. 



Larva, 1st sla>i. — Length about |^ of an inch. A short square-ended 

 larva with a large black shiny head ; in superficial appearance very 

 similar to a young Liparid. Head. — Large, black, shiny, rather 

 square, notched at crown, with stiff black scattered hairs. Bo(h/. — Black, 

 except on dorsal area of the abdominal segments 8 and 4, where the 

 light cream patch (which makes the larva so closely resemble a 

 bird's dropping) is beginning to show. The scutellum large and 

 chitinous looking ; segments, very distinct. Body tapers towards 

 anus, and ends abruptly. Anterior trapezoidals large, bearing only 

 one hair. The posterior trapezoidals are immense, tall and 

 fleshy, bearing numerous long stiff black hairs, nearly half the 

 thijkness of body in length. At tip of hairs there is what appears to 

 be a knob of viscous paste, or drop of liquid. The (?) posterior trape- 

 zoidals on the pro-thoracic segment show up very plainly, though 

 perhaps not much larger than the rest, this still further heightens its 

 Liparid appearance, and, though the position of these tubercules is not 

 the same as the ear tubercles of Liparid, still the superficial resemblance 

 is remarkable. The height of the posterior trapezoidals is nearly, if 

 not quite, one-fifth of the thickness of the body. The folds of skin 

 between the head and the scutellum are pale grey, and shoAv up clearly 

 when the larva moves its head. The ostnatcrium is present in the 

 first skin, and appears very long in proportion to the size of the larva. 

 It is of a pale straw-colour. 



July 5th, 2nil Shin. — The body is not so flat, still rather short and 

 stumpy. Head. — As before, about same size as pro-thorax, or slightly 

 smaller. BikI;/. — The meso- and meta-thorax, and the abdominal 

 segments 1 and 2 are larger than the other segments, the meso-thorax 

 being the largest of all. The body tapers towards anus. The colour, 

 velvety black, with white patch on dorsum of 8rd and 4th abdominal 

 segments. This patch is divided into two by traces of a black medio- 

 dorsal line. (?) Anterior trapezoidals on thoracic segments bear 

 several hairs, but on abdominal segments only one. On the 

 1st abdominal they are nearly as large as on the thoracic. The 

 posterior trapezoidals are tall, conical and fleshy looking, they bear 

 several small hairs. The lateral tubercles are : the supra-spiracular, 

 the post- or pre- and sub-spiracular, the latter being very close together. 

 Numbers of secondary hairs are now present on body. All hairs 

 appear moist at tip, or slightly knobbed. By 9th July the larva was 

 about to undergo second moult. 



I was so busy after this date that I was unable to continue the 

 notes on this species, but as far as memory serves me the larvjo 

 pupated after the 4th moult. The resemblance of the young larva to
