24 Lake Maxinkuckee, Physical and Biological Survey 



38. ANOMALAGRION HASTATUM (Say) 



This is another genus with two types of female, the orange and 

 the black. It is found flying about in the shelter of the pickerel- 

 weed along the shores of Lost Lake and at the South Inlet of Lake 

 Maxinkuckee, and also at Hawk's marsh. It sticks closely to the 

 weeds and does not usually venture very far from them even to 

 get its food. Both sexes alight on the side of a weed stem when 

 ovipositing and the female then backs down into the water. The 

 species was fairly common at the places mentioned. 



Mr. E. B. Williamson of Bluff ton, Indiana, reports the following 

 species not found by the present writer at Lake Maxinkuckee : 



39. Anax junius, May 24, 1900, two males and one female. 



40. Tetragoneuria cynosum, May 21 and 25, 1900, two males. 



41. Tramea lacerata, May 21. and 25, 1900, two males. 



42. Enallagma calverti, May 27, 1900, two males and one 

 female. 



A few of our field notes for May and June, 1901, may be given 

 here. May 1, first dragon-fly seen ; 5th, several dragon-flies ; 14th 

 small dragon-fly; 15th, many small dragon-flies (Agrionids) ten- 

 erals arise out of grass in damp ponds ; 16th, dragon-flies of various 

 sorts, mostly slender, as yesterday, some robust forms; all look 

 pale; 18th, some large dragon-flies seen; 20th, dragon-flies come 

 out of the water, emerging in great numbers; 22d, some dragon- 

 flies came out; 23d, a good many dragon-flies seen, both large ones 

 and slender steel-blue ones; some of the latter copulating; 29th, 

 one large and one small dragon-fly seen ; 30th, several dragon-flies 

 seen. 



June 3, many slender steel-blue dragon-flies copulating on 

 rushes; 6th, great numbers of small dragon-flies in grass near 

 lake; 8th, many dragon-flies, a small slender species coming out of 

 cases at noon ; 12th, dragon-flies, small ones quite abundant. Saw 

 two large teneral dragon-flies in morning and several larvae in 

 afternoon; 17th, multitudes of small blue-green dragon-flies near 

 Outlet Bay in evening; 20th, dragon-flies laying; 21st, good many 

 small dragon-flies; 22d, dragon-flies plentiful. 



In 1904, a rather slender red-bodied dragon-fly was noted ovi- 

 positing, and another was seen October 18. They seemed at this 

 time to be the most abundant species. They were noted copulating 

 and flying about October 26 and 27 and so on until November first. 



Two years after the completion of the above list, another visit 

 was made to the lake earlier in the season and a number of addi-
