THE entomologist’s RECORD. 
the narrow end forward, between the anterior trapezoidals and 
the supra-spiracular. The dorsal tubercles of 3 and 4, being 
apparently fused trapezoidals, have each two hairs, all the 
other tubercles have each one long black hair. The plate of the 
2nd segment has four hairs on either side. The trapezoidal 
and supra-spiracular tubercles of ii are very small, and not so 
markedly angulated. The trapezoidals of 12 are large, 
rounded, and the posterior set immediately behind the an- 
terior, again a common arrangement in Acronycta and many 
other larvae. The tubercles are fuscous rather than black, the 
head black. Below the sub-spiracular there is a small ventral 
or “ marginal ” tubercle in 5. 6, ii and 12. The colour of the 
segments, that is the skin of the larva, is reddish brown on 
the 5th, 8th, gth and 12th, pale or whitish on the others. In 
psi, which is also somewhat larger, the 13th segment belongs 
to the coloured series. 
In the 2nd skin, the tubercles are large and black, and still 
present in a marked degree the form due to apparent mutual 
pressure, being flattened towards each other and angular. 
They have developed, as regards the number of hairs each 
carries, and certain coloured markings are already manifest. 
The trapezoidals are conical in form, terminating in a long and 
strong hair and possessing half-way up a circle of four to seven 
small short hairs. On the iith segment these tubercles are still 
simple, with only one hair each, and are remarkably small in 
contrast with those of the other segments, in the 5th segment 
there is already a tendency to a hump, due to the large size 
and tendency to coalescence of the anterior trapezoidal 
tubercles; all the trapezoidals are also of large size on 12. 
A lateral view of the larva gives a very echinate appearance, 
due to the pyramidal tubercles, with the raised bases of the 
secondary hairs. The secondary hairs of the supra-spiracular 
are less pronounced and the post-spiraculars dwindle, but are 
still obvious, with one hair. The sub-spiraculars are linear 
longitudinally, and possess two hairs, whilst the marginal 
tubercle possesses a similar form. 
When somewhat grown in this (2nd) skin, the larva is 
already more brilliantly coloured than psi at the same stage ; 
the dorsal band is orange, instead of whity-yellow, and is not 
interrupted except in the 5th segment, where the large black 
anterior trapezoidal tubercles stand up as a hump in its way, 
and, on the 12th, it runs as a narrow white line between the 
tubercles and forms a white cross ; the 13th segment is rich
