KELLICOTT. 



to those of the young males, often darker apically, 

 especially on the hind wings; the pterostigma 

 ( absent in the male ) is milk white, broad and reticu- 

 lated ; it varies greatly in size, but is always relatively 

 broad. 



This species is found throughout the State, and is 

 abundant in most localities. It prefers small streams, 

 especially the meadow-brooks and the clear, cool rivu- 

 lets from springs among the hills. It also occurs by 

 the borders of larger living waters where the banks are 

 overhung by foliage. In this form, the male does not 

 always seize the female with his feet previous to clasp- 

 ing her prothorax with the abdominal appendages. 

 He flits about her, when at rest, gradually approach- 

 ing, and, finally, the female not attempting to avoid 

 him, he poises himself with sufficient accuracy to pick 

 her up by the prothorax, when they fly away together. 

 The female places her eggs among the rubbish and mud 

 along the borders of the ditches. 



In central Ohio it occurs from May 15 to Sep- 

 tember; it is most abundant in June. 



It is perhaps true of all of this sub-family, but 

 especially true in case of maculata that the males en- 

 gage in fierce battles. Two combatants will fly about 

 each other, evidently with consuming rage, when one 

 finally appears to have secured a position of advant- 

 age and darts at his enemy attempting, often success- 

 fully, to tear and damage his wings. These battles 

 often last a long time, until the participants are ap- 

 parently exhausted. Sometimes a third and a fourth 

 happen along and "take a hand" when the melee be- 

 comes general, each doing his utmost to damage any 

 other that he can seize.
