576 NEW YORK STATE MUSEUM 



Head retracted within the prothorax, only the blunt tips of the antennae 

 showing at the sides. 



Color greenish brown, darker toward the head and on the dorsum of 

 the penultimate segment, paler on the ventral surface, and most trans- 

 parent on the sides of the body. 



Each of the middle abdominal segments has a secondary transverse 

 groove at two thirds its length, and on its posterior third a transverse 

 line of setigerous tubercles, from which another line extends anteriorly 

 at the sides of the dorsum ; the seta at the posterior end of this lateral 

 row is much longer than any of the other setae. The yellow color on 

 these setigerous ridges forms the basis of the color pattern, which con- 

 sists elsewhere of multitudinous spots that are mainly arranged sym- 

 metrically in pairs. 



Anal prominence pale yellowish, bearing at its sides three pairs of 

 similar, equal appendages, each about as long as the greatest diameter 

 of the body. The respiratory disk bears three pairs of marginal lobes or 

 teeth, and, between the base of the lowermost or ventral pair and the 

 anal prominence, a conspicuous, setigerous tubercle. The six marginal 

 lobes are all blunt at the apex, where they bear a few, fragile hairs, and 

 are covered except on the posterior face with a close, brownish 

 pubescence. Paired black lines extend up the posterior face of each lobe, 

 and at the base of these lines there is, on each lobe of the lowermost 

 pair, a pair of black spots. Between the brown, cup-shaped, spiracular 

 openings there is a pair of black marks.

 description) 

 This fine soldier fly was not uncommon along the railroad track east 

 of the Saranac Inn station on small clumps of goldenrod during August. 

 On August 12 Dr O. S. Westcott and I collected a few, finding them asso- 

 ciated with the wasp-mimicking conopid, Physocephala furcil- 



1 a t a Will., and wasps of many species and cerambycid beetles. The flower 

 clumps were rather few and small, and collecting from them was ex- 

 cellent. 



A single stratiomyiid larva was taken during the season. It clearly 

 belonged to the genus Stratiomyia, of which this was the only 

 species observed. 



Larva. Length of body 27.5 mm, caudal tuft of plumose hairs 



2 mm additional ; greatest diameter (across base of abdomen) 4 mm ; 

 width of head 1.7 mm. Color uniform blackish.
