THE SYRPPIIDAE OF OHIO 73 



with a pair of black spines, the posterior one curved backwards; above 

 the spines are small brown papillae; the posterior portion bears on each 

 side three large, hairy, spine-like processes, and terminates wdth a promi- 

 nent, shin}' brown respiratory tube, showing slight annulations on the 

 middle. 



"The larvae \vere collected near Auburndale, Mass., March 26, 1905. 

 The}^ commenced pupating March 3 r , and continued to do so until April 3, 

 the imagos appearing from April 12 to 15. The pupa is about 10 mm. in 

 length; dark brown in color, the black spines and small papillae of the 

 larva being still present with an additional pair of larger papillae above; 

 the posterior portion also has a similar appearance to the larvae, retaining 

 the lateral processes and respiratory tube. The imago emerges thru the 

 upper portion of the first two .segments."

 Verrall, Brit. Flies, p. 623. 



Brachypalpus — Reared from larva found between loose bark on 

 stump of a tree.^E. L,. Keen, Canad. Ent. Vol. 16, p. 149, 1884. 



' ' Metamorphoses probabh' occur in rotting portions of living trees. " — 

 \"errall, Brit, Flies, p. 593. 



Pocota — "It lives in rotten poplar {Popitlns) stems. Metamorphoses 

 well known, it .seems to be more frequently bred than caught." — \''errall, 

 Brit. Flies, p. 587. 



Criorhina — "The metamorphoses are but little known, but the species 

 are associated with the sap of rotten wood, probably occur in the sap 

 which flows from injured or ulcerated trees, or the debris of floods from 

 whicli C. oxyaca)ithae \\3.?,hQQnhre<i.'' — Verrall, Brit. Flies, p. 576, 577. 



Sub-Family Milesinae (Verrall) — "What little is known about the 

 metamorpho.ses shows that many species live in rotten wood or about the 

 sap flowing from injured tree trunks." — Verrall, Brit. Flies, p. 561. 



Ceria — The following notes on the puparium of C. signifera are 

 given by C. W. Johnson, Ent. News, W. 91. "This specimen (female) 

 was given to me by Dr. Henry Skinner; with it was a card, to which was 

 attached a leaf, and on this was a small pui)a-ca.se. On the card was 

 written: 'Found near Bala, Pa. Dead oak leaf on ground; hatched May 

 13, 1889.' It is evidently the pupa of this fly. It is about 12 mm. in 

 length ( the anterior part being broken in hatching) the ground color 

 brownish-gray, roughly and irregularly netted with black. There is a 

 dorsal, binate row of dark l)r()wn tubercles with single lateral rows alter- 

 nating with those on the back; above and l)el()w the lateral row there is
