being moderately short. The eastern specimens, of both forms, 

 have the second antennal joint longer, and the third joint only 

 about one and one-half times as long as second. 



The typical form was identified by Coquillett as Calliphora 

 splendida Macquart, and specimens of the other form were 

 included in the series so labeled by him. Macquart's specimen 

 was from Galveston, Texas, and the size was given as five lines 

 or 10 mm. The thorax and scutellum were stated to be black, 

 the abdomen greenish-blue with tip golden. The first two 

 antennal joints were said to be very short, and testaceous in 

 color. Also the wings were said to be fuscous on costal border. 

 On account of these discrepancies, I am unable to identify 

 the present forms as Macquart's species, which appears cer- 

 tainly to be a synonym of chrysorrhea Meigen.
