Lake Maxinkuckee, Physical and Biological Survey 29 



weaken, particularly on the coolest nights, when it would give only 

 a few very weak calls, usually consisting of "she did" ; sometimes 

 of "she did, she did," slow, deliberate, and weak. On the night 

 of October 24 we heard a single low, weak, slowly uttered "she 

 did," after which it became quiet and we heard it no more. 



Crickets, especially the common black field cricket {Gryllus as- 

 similis lactuosus) , were fairly common and musical, especially in 

 the fall. Our notebooks have many records of their singing, the 

 earliest entry being May 17. From then on they were heard almost 

 nightly and often in the daytime, until November 22. Mole crickets 

 {Gryllotalpa) are rather common about the lake. Their burrows 

 may be often seen in the sandy beaches. Their interesting musical 

 note can often be heard, especially in August. Tree crickets were 

 abundant, especially in low copses and thickets and, more than 

 anything else except perhaps the katydids, made the autumn nights 

 musical. 



The following species of Orthoptera have been identified as oc- 

 curring about Lake Maxinkuckee : 



Diapheromera femorata Say 

 Chorthippus curtipennis Harr. 

 Dissosteira Carolina Linn. 

 Melanoplus atlanis Riley 

 Melanophts bivittahis Say 

 Melanoplus differentialis Thomas 

 Melanoplus femur-rubrum DeG. 

 Melanoplus fasciatus (Barnston-Walker) 

 Scudderia curvicauda DeG. 

 Pterophylla camellifolia Fabr. 

 Neoconocephalus robustus Scudd. 

 Gryllus assimilis lactuosus Serv. 



ORDER HEMIPTERA 

 Bugs, Cicadas, Aphids, and Scale Insects 



Of all the groups of insects found in the lake and in the immedi- 

 ate vicinity, the least attention was paid to the Hemiptera or bugs. 

 In the course of seining, raking weeds, taking plankton, etc., vari- 

 ous forms would attract the attention either because of form, color, 

 habit or abundance, and these would be preserved for identification. 



The Water Boatman, Corisa (Arctocorisa) inter rupta Say, ap- 

 pears in our collection and was probably common in the lake. We 

 have no special notes concerning it.
