20 Lake Maxinkuckee, Physical and Biological Survey 



22. LESTES FORCIPATUS Rambur 



Nearly as large as vigilax, the males with slender and nearly 

 black abdomens, the pterostigma entirely black in both sexes. 



This is also a swift flier and a frequenter of the marshes and 

 sedges, but it does not seem to remain concealed as persistently as 

 unguiculatus. Williamson says it is the first of its genus to ap- 

 pear in spring, and it was found late in August at Hawk's marsh, 

 where it was taken in connection with the preceding species. It 

 was not found elsewhere. 



23. LESTES VIGILAX Hagen 



Notably larger than the preceding species and more brightly 

 colored, its colors, however, harmonize so well with its environ- 

 ment as to effectually conceal it. It is a slender and graceful spe- 

 cies, preferring the rushes and weeds around the lake rather than 

 along the streams. Its eggs are deposited amid the rush stems 

 and the sedges, the sexes pairing during oviposition. The male 

 retains such a firm hold of the female at this time that the two may 

 not only be taken together but they may be killed and placed in the 

 preservative still fastened together. 



Found in special abundance in Lost Lake around the Outlet and 

 at the South Inlet of Lake Maxinkuckee and rarely along the west- 

 ern shore of the latter lake. 



24. ARGIA MOESTA PUTRIDA (Hagen) 



A large and dull-colored species which frequents the open shore 

 where there is plenty of sunshine. They do not alight so much 

 as the other species on the weeds and grasses but upon boards, 

 sticks, stones, etc. They are not as lively as the other species and 

 allow a close approach and easy capture. 



In every instance observed the eggs were being deposited in 

 the yellow, filth-laden algas close to the shore. The male also, in 

 these particular instances, held his body suspended above the fe- 

 male at an angle of about 45 by the rapid vibration of his wings. 

 He was not seen to be drawn under the female, but the observa- 

 tions were very limited. 



Found only at Aubeenaubee Bay in Lake Maxinkuckee and amid 

 the pickerel-weed on Lost Lake. 



25. ARGIA VIOLACEA (Hagen) 



A common species which remains all summer and may be found 

 along the shores of the lake anywhere. It prefers the dense vege- 

 tation close to the shore, and is also found along the banks of the
