148 THE entomologist's record. 



thick, the general outline similar to a Tcsniocampa, 15 mm. long, 

 of which the free abdominal segments (9th-i4th) are only 

 5 mm. ; the width is 5 mm., the widest part being about the 

 4th abdominal segment. The colour is brown, tending 

 dorsally to black, especially along the posterior margins of the 

 4th, 5th and 6th abdominal segments. The head, legs, and 

 wing cases are very smooth and polished, but the remainder of 

 the pupa, especially dorsally, is sculptured in a very definite 

 manner, of which only the dimmest suggestion is to be found 

 in any of the Cuspidics. A special pattern affects the dorsum of 

 each segment, viz., two furrows or channels crossing from side 

 to side, leaving a median and two marginal ridges. On the 

 prothorax these furrows meet laterally ; the anterior is inter- 

 rupted in the middle line by a very slight ridge, but the second 

 is so interrupted as to present only two ends and two pits 

 between the divided ends. On the mesothorax, the pattern is 

 so modified by the expansion of the median ridge and central 

 interruption, as hardly to come within the definition of the 

 pattern which is fairly applicable to the other segments. 



The furrows form a horse-shoe shaped depression, with the 

 convexity forwards, and the posterior ends dilated, leaving in 

 its centre a raised surface, shaped like a heraldic escutcheon or 

 shield. On the metathorax, the furrows coalesce and the 

 dividing ridge is represented by only a faint elevation in the 

 dilated ends of the furrow. 



On the first abdominal segment, the median ridge is divided 

 on each side of the middle line. On the following segments, 

 the pattern is more typical, the median ridge widens at its 

 extremities, and flattens out to join the marginal ridges, and in 

 the flat portion the spiracles are situated. The marginal 

 rido^es of adjoining segments are separated by a sharp but 

 narrow incision, so that the pupa appears to have alternately 

 double and single ridges transversely. All these ridges, from 

 the posterior thoracic margin to the median ridge of the 7th 

 abdominal segment, are very sharp and well-defined. There 

 are no minute pits as is so usual with Nocxu^. The pro- 

 thoracic spiracle is distinct, the six abdominal spiracles are oval 

 and have a shallow depression behind them. The pupa tapers 

 to a point behind, which has, however, a very definite though 

 minute armature, consisting of eight short points hooked down- 

 wards (towards the venter), disposed almost in the pattern of 

 the hooks of tridens, two being dorsal, and the other six in a 

 line anterior to this, the central ones being the largest. There
