Lund's Larva. 



Endemic in the region of the Congo State ; called after Commander Lund, from 

 the skin of whose arm it was extracted ; 12*5 mm. long, 4*5 mm. broad ; colour 

 yellowish, with brown rings, on account of the division of the brown spines ; head 

 cone-shaped, with two hemispherical smooth antennas, two thick black mouth hooks 

 and wart-shaped bodies, between which are situate two to three longitudinal rows 

 of dark brown chitinous laminae. The body segments are covered over their whole

surface with irregularly distributed triangular yellow spines, the points of which are 

 coloured dark brown. Its size increases from the second to the sixth segment, 

 diminishes from the seventh to the ninth, at the tenth it is reduced, and at the 

 eleventh quite small. The posterior stigmata are bean-shaped, each with three 

 markedly tortuous openings. Duration of the larval stage unknown ; the same 

 applies to the pupal and imago stages.
