The State list now numbers 91 species of Odonates. Four of the above ad- 

 ditions are due to Mr. Weith, who has also added several species, known from 

 other points in the State, to his local list. Collections are being made at Lake 

 Maxinkuckee, Winona Lake, Evansville, and perhaps at other points, so further 

 additions to the list may be expected, and our knowledge of seasonal and geo- 

 graphical range within the State is certain to be augmented. Descriptions of two 

 of the species mentioned above are unfortunately not found in "The Dragonflies 

 of Indiana." They are given in the notes which follow.
