 The spot on the front above is black. The rings said to sur- 

 round this spot are interrupted for a considerable distance at 

 the back. The inner ring is yellow, not green. The outer 

 ring is blue only in front and fuscous at the sides. The blue

74. Hacromia illinoiensis Walsh. 



This beautiful species was taken in considerable numbers 

 from June 15th to July 15th at Orono and Bradley. The 

 Orono specimens were taken in open woods along roads, the 

 Bradley specimens along the Penobscot River. The}' were 

 flying up and down the rocky shore. We waded out to their 

 line of flight and took ten in one hour. The specimens are 

 quite variable as to the spots on the abdomen. Eight speci- 

 mens examined had two spots on dorsum of 2. Usually no 

 dorsal spots on 5 and 6, but one male and one female had 

 dorsal spots on these segments. All the males examined had 

 two spots on dorsum of 8, but only one female was so marked. 

 Yellow spots on thorax at dorsal base of wings. Wings some- 

 times hyaline, often fumOvSe throughout. 



66. Gordnlia Shnrtleffi Scud. 



Taken in 1898 in Bradley over a small meadow brook. We 

 have taken only two specimens.
