hatching, may be seen opening and closing within the shell, and the 
larva projecting its segments up and down within the little space at 
its disposal. 
A good way to hatch out the eggs is to remove them, in 
their batches on very small portions of the bark to which 
they are attached, with a penknife. Place them on a plate 
and cover them over with a flower-pot, moistened occasion- 
ally if the weather is very hot and dry. The pot should not 
be exposed to any fierce heat. With the aid of the lens 
the young larve may easily be seen when they hatch out, 
and each day’s hatch gathered up with a fine brush and 
placed on their food. 
Should ova become detached from the bark they may 
be reattached by very slightly moistening the bark with a 
weak solution of gum arabic and laying the ova on it. I 
have found these hatch out as well as others if they are 
very lightly touched. 
Left loose at the bottom of the jar they hatch out equally 
well. On one day in September 1906 I took upwards of 
40 healthy young larve from the bottom of a jam Jar, 
where the 2 had laid them in some wood-dust which 
adhered to the glass, the ova, with hardly an exception, 
hatching out successfully, a very unusual thing for late 
autumn eggs of a second brood. 
Tue Larva (Plate XX, fig. 1).—Fleshy, susceptible ; scantily 
clothed throughout with short hairs: with legs small and slightly 
corneous: scansorial prominences present on ventral surface of 
abdominal segments. 
Widest in front, a little wider than } of whole length. Pro- 
thoracic segment bearing scutum widest of all, capable of receiving 
the rather large head, which for the most part is retracted into it. 
Tapering from the prothoracic segment to the 6th abdominal: 7th 
and 8th explanate below the spiracles. Prothoracic segment slightly 
corneous above, equal in length to meso- and metathoracic segments 
together. First four abdominal segments subequal: 5th to 8th 
the longest. Spiracles present on mesothoracic and first eight 
abdominal segments as in Asemwm and Criocephalus ferus. Mandibles 
longer, in proportion to their size, and narrower on the biting surface 
than in Asemum. Two blunt corneous tubercles on the dorsal 
surface of the 9th abdominal segment, set closer together than the 
corresponding spines in Oriocephalus and Asemwm, and inclined 
slightly inwards (Plate XX, fig. 4). In asingle instance only I have 
known these absent in a full-fed larva. In this case the larva had
