Sarcophaga ? pitnct'ipennis, 



Fcem. — Nigra, cinereo-tomentosa, capite antice argentco, thorace 

 vittis quatuor nigris, abdomine asneo-nigro, fasciis interruptis

 somewhat short and depressed, with an interrupted white band on 

 the fore border of each segment ; wings grey ; veins black ; a black 

 dot on the veinlet between the cubital and the praebrachial, one at 

 each end of the discal transverse vein, and one on the flexure of 

 the praebrachial ; praebrachial vein forming an acute but rounded 

 angle at its flexure, near which it is very much curved, almost 

 straight from thence to the tip, which ends at very far in front 

 of the tip of the wing ; discal transverse vein curved near its 

 base, and forming an angle near its tip, parted by much more 

 than its length from the border and by much less that its length 

 from the flexure of the praebrachial ; alulae white. 



Length of the body 83 lines ; of the wings 7 lines.
