The use of ground, unslaked lime or naphthalin is advised byCollinge for the destruction of larvae of the allied Bibio marciLinn, in leaf mold, in which they occur. REPORT OF THE STATE ENTOMOLOGIST I913 67 Bolitophila cinerea Meign. Numerous white, black-headedlarvae of this species were found in the base of a decaying, probablyfungous-infected, birch stump at Albany in March, the adults issu-ing early in April. The larva appears to be unknown and isdescribed below. £. x 6 y(2Q Larva. Length 4 mm. Head shining jet black. Body white,with jet black tubercles. The head is moderately large, having awidth fully two-thirds that of thebody and with moderately well-de-veloped triarticulate or possiblyquadriarticulate palpi. Each an-tenna is supported upon a broadbase surrounded by a narrow ringof fuscous chitin, possibly the firstsegment; the next segment is cylind-ric, tapers slightly and has a lengthone-half greater than its diameter;the third segment is conical andabout 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 slightlyto a somewhat narrowed, subtriangular terminal segment. Ventralsurface, the margins of the abdominal segments broadly bandedwith transverse lines of fine, chitinous points resembling somewhatthose of Miastor.
