Bolitophila cinerea Meign. Numerous white, black-headed 

 larvae of this species were found in the base of a decaying, probably 

 fungous-infected, birch stump at Albany in March, the adults issu- 

 ing early in April. The larva appears to be unknown and is 

 described below.

Larva. Length 4 mm. Head shining jet black. Body white, 

 with jet black tubercles. The head is moderately large, having a 

 width fully two-thirds that of the 

 body and with moderately well-de- 

 veloped triarticulate or possibly 

 quadriarticulate palpi. Each an- 

 tenna is supported upon a broad 

 base surrounded by a narrow ring 

 of fuscous chitin, possibly the first 

 segment ; the next segment is cylind- 

 ric, tapers slightly and has a length 

 one-half greater than its diameter; 

 the third segment is conical and 

 about one-third as long as the pre- 

 ceding; the terminal segment is very 



slender, about two-thirds the length of the preceding. Body stout, 

 apodous, the segments distinct ; posterior extremity tapering slightly 

 to a somewhat narrowed, subtriangular terminal segment. Ventral 

 surface, the margins of the abdominal segments broadly banded 

 with transverse lines of fine, chitinous points resembling somewhat 

 those of Miastor.
