2. Larva — incertae sedis ; — an Dmcmm cujusdam ? 



I am induced to think it probable that this may be the 

 larva of a Dircaea (Xylita, Paykull), from its almost per- 

 fect accordance with Mr. W. S. Macleay's description of 

 the thysanuriform larva of the Xylita buprestoides, (Horse 

 Entomological, note, p. 464.) As Mr. Macleay's work is, 

 unfortunately, very rare, it may be useful to transcribe 

 his description : — " Larva, whitish, elongate, scaly, 

 " with few hairs, except about the last segment of the 

 " abdomen ; body thickest at the middle and tail, upper 

 " side rather convex, under concave ; head semi- 

 " globular, with vestige of eyes ; antennas Particulate, 

 " short, with the first joints greatest; mandibles short, 

 " strong, and sharp ; maxillary palpi acute at point, 

 " and labial excessively minute; second segment of the 

 " body large, subthoraciform, and composed apparently 

 " of two segments ; anterior feet large, compressed, 

 " hooked, extending nearly to the top of the head ; 

 " the two posterior pairs of the same shape, but so 

 " short as scarcely to reach beyond the coxa of the 

 " first pair, besides being in some measure hid in the 

 " concavity of the body ; the third segment of the body 

 " is shortest, and the others lengthen gradually to the 

 " 12th, which is convex, and marked with strongly 

 " impressed points ; but the singular part of the body is 

 " the tail, or 13th segment, at the base of which is the 

 " anal aperture : this segment is slightly convex above,
