(7.) The large pentagonal areas below Cu 3 in hind wing are shown 



in the figure. There is a suggestion of something similar in 



JE. juncea. 

 (8.) The forking of the radial sector occurs considerably anterior to 



the stigma, especially in the hind wing. This is like M. con- 



stncta and calif oniica, not like jinicc:i. 



I am much indebted to Mr. E. B. Williamson for the loan 

 of a number of photographs, which greatly facilitated the 

 above comparisons. The recognition of the identity of Dolac- 

 schna with Oligoaeschna is due to Dr. Calvert.

THREE MOUND BUILDERS. 

 BY ABRAM HERBERT MANEE, A. M. 



(Plates XX and XXI) 



As reported to me by Mr. E. A. Schwarz through Dr.- L. 

 O. Howard, the genus Bradycinctus is confined to Central and 

 North America, the only species in the Atlantic States is 

 ferrugineus; nothing hitherto known of habits save that in 

 Florida it is taken late at night as it is attracted to light ; 

 species rare. 



In winter of 1904-5 I found a fragment of a male with thorax 

 under a board. This was probably the first specimen taken in 

 North Carolina. About 9 P. M., on June 5, 1905, two males 

 came to our window as we were light hunting for moths. On 

 July 16, 1906, our discovery of the haunts of Strate^us antacus 

 suggested to my wife the probability of finding more of our 

 species not yet identified and which I classed as a Bolboccras. 

 Finding a four-inch mound in our yard, Mrs. Manee soon 

 dug out a lively pair of B. ferrugineus and a few minutes later 

 two other mounds each disclosed a pair, and that summer we 

 unearthed over sixty specimens. During the three seasons of 

 'o(S, '07 and '08 we have taken over TOO specimens, whereas 

 had we not known the day haunts our entire find would have 

 comprised not more than 4 specimens and those all males. 



The beetles fly and evidently mate at night. T have ob- 

 served a male moving about but a few inches above the earth
