206 THE CANADIAN ENTOMOLOGIST. 



The type is just transformed, as is proved by specimens from Ala- 

 bama, which made their transformation on the same day ; one has all 

 four wings developed, one only the fore wings, and the third has all wings 

 crumpled. Nevertheless they have all the same colours of the type, and 

 it is to be supposed that older specimens will show a darker coloration. 



I have never seen more specimens. When I published the synopsis 

 I had before me the type of Burmeister and two specimens of M. imma- 

 culatus, and believed all three to belong to the same species. 



Myrmeleon formicalynx L. 



The synonymy need not be repeated here ; compare Stett. Ent. 

 Zeit., 1866, p. 439.

 in shape and size, and an engraved spot in the middle between the

 face ; mouth yellow.

 or less pronounced median impression, on top with a transversal corrug- 

 ated band, and some glossy flat spots ; two approximate anteriorly and
