ox ALIJCITA (ORNfiODEs) HEXADACTYLA. 260 



present are : — anterior and posterior trapezoidal, one supra-spiracular, 

 two sub-spiracular, or rather one with two bristles, and two 

 marginal, represented by hairs whose length is about one-sixth of 

 the diameter of the larva ; there are two hairs on the foot 

 base, the skin is rough, with very minute sharp spicula3 y^T^th 

 of a millimetre in length. The jaws are not so much like a 

 mole's paw as are those of the newly-hatched larva, but are of a solid 

 triangular form, with the inner surface rather hollow and scoop- 

 shaped just below the teeth ; the antenna is the same as in the young 

 larva, save that it is rather more slender ; the two terminal processes 

 are of about equal size, and each has two hairs with a long stiff 

 bristle between them ; the maxillary palpi also are like those of the 

 young larva, their terminal bristles comparatively minute ; the 

 labial palpi have a long basal joint and a short terminal one carrying 

 a bristle. The legs have three joints, each furnished with half a 

 dozen hairs, and terminate in a well-hooked -claw, the battledore 

 appendage being very small. The pro-legs have complete circles of 

 fourteen strongly curved hooks at the end of a short pedicel ; the 

 anal pro-legs have twelve hooks situated on the margin of a rather 

 open horse-shoe. The hairs are longer on the head and on the 10th 

 abdominal segment than elsewhere. 



The pupa remains in the cocoon on the emergence of the imago ; 

 only the 5th and 6th abdominal segments are movable, the wing and 

 leg-cases being attached to the first four. On the emergence of the 

 imago, the wing-, antenna-, and leg-cases remain attached together, the 

 antenna-cases separating from the head. The pupa is 6 mm. in 

 length, and in general proportions and outline is very like that of a 

 NocTUA, say of Orrhoilia racrinii. It is pale brown and somewhat 

 delicate ; the terminal armature also reminds one a good deal of that 

 of a NocTUA ; it consists of a double bunch of hooks, ten or twelve in 

 number, with slender shafts ; these are curved and cross each other 

 lyre-fashion, their extremities being a little flattened, and curved 

 roimd into a small closed circle. The hairs present are two on each 

 thoracic segment and one on each abdominal segment on each side, 

 one above and one below each abdominal spiracle (where not 

 covered by wings). The hind- wings do not finally disappear beneath 

 the fore-wings till near the hind margin of the fourth abdominal 

 segment. The customary six abdominal spiracles are large and well 

 developed, as also is that of the first abdominal segment beneath the 

 wings. The first spiracle is likewise large, and is protected by the 

 usual shield of pro-thorax, which is finely spiculated. The labium 

 and jaws are better marked than usual, whilst the cheek beside 

 projects doAvnAvards and terminates in a right angle, the central 

 portion of the maxilla occupying the intermediate space. The front 

 appendages are the two antennte, which terminate level with the second 

 pair of legs and a little short of the wings — the third pair of legs 

 appear from beneath the second and project a little beyond the Avings ; 

 the first pair of legs are nearly three-fourths of the length of the 

 Avings, and fall a little short of the maxillfe ; the femur and 

 trochanters of the first pair of legs appear betAA'een the maxillae and the 

 first legs, even more than is the case in many Noctuides. There are no 

 maxillary nor any labial palpi. The Avings are rounded in place of 

 having an anal angle, but are squarer at the apex than in most of the
