ON DEEMAPTERA PRESERVED IN AMBER, FROM PRUSSIA. 



? Pygidickana sp. (PL 31. fig. 13.) 



No. 4181. 



Another young larva. The body is 3 mm. long and the forceps also 3 mm. long ; these 

 are quite straight and hairy, with no visible trace of segmentation : the femora are 

 unusually broad, and the tarsi short and slender, though I think I can detect a slight 

 dilation on one of the second segments. But the whole appearance of the creature is 

 that of a larva of a JPygidicrana : the broad femora, especially, are suggestive of the 

 latter, a group which is now confined to the tropics. The four or five antennal segments 

 are, however, long and slender, and not quite short as in that group.
