26 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 11 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, 11 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 r3th 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 nth 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
