This insect is very common and quite characteristic of the upland 
bogs, the gorges and deep, cold Canadian woods in May and June. 
From the tent-trap observations made in 1914 by Miss Ruby B. 
Hughes, at Ithaca, N. Y., ifc is quite certain that the l^rva lives, in 
wet earth near water.

lateral margins of the sclerite pale, yellow; scutum with the median 
area pale yellow pollinose; the lobes dark brown, enclosing two 
paler brown areas, of which the larger lies proximo-caudad; scutellum
