NOTES ON LAPHYGMA EXIGUA. S 



and posterior to iv, is present, and well-developed in this skin, as is the 

 case with some Noctuid larvte, and vi, the other subprimary, as a 

 minute hair, is in evidence beneath v. Owing to damage done to the 

 larva in mounting, I can only make out the base of vii, and its exact 

 location cannot be determined, as the leg has been torn off. On the 

 abdominal segments, iii is situated close above the spiracle, iv close 

 beneath, and v still further below on the raised area that forms the 

 lateral flange ; vi below v is well-developed, and a marginal group (vii) 

 consisting of either one or two hairs. [Tubercle vii has two hairs on the 

 1st and 2nd abdominal segments of adult larva.] The spiracles are 

 distinct with slightly raised black rims. The small tubercular point, 

 slightly above and anterior to spiracle, is very distinct for so small a 

 larva, as also is the marginal one in front of ii. 



Note. — The tubercles of the adult larva are the same as in the 

 larva in its first skin, and their positions are practically unaltered. [1

Pupa. — Described from a dead and somewhat shrivelled specimen. 

 Length 10-50mm. It is very much shrunken dorso-ventrally ; the 

 greatest thickness is at the metathorax (B-50mm.), where the strong 

 dorsal plates have withstood the forces that have elsewhere caused it 

 to collapse. In shape it was probal^ly tolerably cylindrical, short and 

 full, being relatively long to end of wang-cases at 4th abdominal 

 segment. The abdomen beyond this has suffered greatly from shrink- 

 age, and it is not possible to say with any chance of accuracy what its 

 shape may have been. The head is l)lunt and rounded ; head, eyes, 

 &c., being rather prominent ventrally. Colour bright brown, and 

 surface as a whole smooth and shining. Anus smooth and somewhat 

 blunt, its armature, which possibly may have received some damage, 

 consists of two low conical processes with blunt points, these are 

 situated a short distance apart, and point slightly away from each 

 other. In addition to these, and situated near one of them, is a single 

 slender spine, without hook, taller than the conical process. Probably 

 it had a fellow near the other process, but if so it was broken off. 

 The spiracles are large and distinct, oval, with raised rims. The 

 upper portions of the 4th, 5th, 6th, and 7th abdominal segments are 

 coarsely and deeply pitted, the pits being very deep and rather closely 

 set ; on the anterior abdominal segments this pitting is only faintly 

 marked. There are no traces of setae on the abdominal segments under 

 1" objective, but there are two or three short and fine hairs on head- 

 piece. Ventral head-pieces are prominent and glazed, eyes large. 

 There are two small centrally situated covers beneath labrum and 

 between the maxilla' representing the labial palpi. The maxilhe are 

 very broad at base, and extend to very near the end of the wing-cases. 

 The antenna-cases are raised, but narrow, and extend about the same 

 distance. The covers of the first pair of legs do not extend more than 

 half way. The second leg-covers to end of wings, and tips of third legs 

 just protruding beyond them. The wing-cases are somewhat darker 

 than the ventral shield and the other parts of the pupa, excepting the 

 anterior margins of the lower abdominal segments.
