KELLICOTT. 87 



male are not present. The species is common in the 

 north western part of the state along the Manmee 

 River. The males fly well out, and consequently are 

 seldom taken, the females oviposit among leaves and 

 alga? near the shore. 



Macromia illinoisensis, Walsh. 



Length: of abdomen cT 48-50, 9 50; hind wing, o 7 * 

 45 9 46. 



Male ; colors fuscous, brown and yellow. Head 

 very much as in ta^niolata. Thorax brown or fuscous 

 with metallic greenish reflections. Yellow before the 

 base of the anterior wings, and lateral band present as 

 in the latter species, btit the antehumeral absent. 



Wing hyaline often brownish tinted, more promi- 

 nently at the apex. Superior yellow markings, often 

 very small, on abdominal segments 2, 3, 4, 7 and 8, oc- 

 cupying nearly a third of 7 at base. This last is 

 strikingly prominent when the species is on the wing. 

 Superior appendages much as in taeniolata, but more 

 gradually narrowed towards the apex ; slightly longer 

 than 10. Inferior appendage about as long as the su- 

 periors, conical, apex elevated. Female differs in having 

 superior yellow markings on segments 2—7 and the 

 wings are often more uniformly brownish. 



The species flies most commonly during July, and 

 may be seen at times some distance from water. I have 

 taken the female flying over ripples of our larger 

 streams, and a pair in copulation resting on alow bush 

 not over two feet from the ground. It is more common 

 than the preceding species and may be expected in any 

 part of the state. 



Its smaller size will separate it from tseniolata. 



DIDYMOPS, Rambur. 



The single species of ^this genus is commonly taken 

 in Ohio. We have found it most common in May,
