OF WASHINGTON, VOLUME XIII, 1911. 181 



This pretty North American species has a striking resem- 

 blance to Leptostyla constricta Champ., described from Guate- 

 mala and Panama. It differs, however, in having the costal 

 margins less sinuate behind the middle and the elytra not 

 narrowing toward the apex; besides, it seems to be even 

 smaller than Champion's species. At the present time the 

 species is known only from this region and from Texas. It is 

 found close to the ground on a small Leguminosae, Clitoria 

 mariana, from the month of June to October.

 from the bald cypress, which are extensively eaten by wild 

 ducks. He also showed a female seventeen-year Cicada, to 

 which a hind part of the abdomen of a male was still coupled, 

 which had been caught in Arlington, some bird having 

 probably been responsible for the tragedy.

 nomic groups,' which was discussed by Dr. Howard and Mr. 

 Rohwer.
