THE IDENTITY OF LEPTOFCENUS F. SMITH AND 
PELECINELLA WESTWOOD (HYMENOPTERA). 
By Chakles T. Brues. 
Bussey Institution, Harvard University. 
In 1862 Frederick SmitD described as Leptofoenus a 
peculiar Hymenopterous insect of doubtful affinities which he 
says unites some of the characters of Fcenus (Gasteruption), 
Megischus and Pelecinus). A recent examination of this paper 
led me to compare his description with a specimen of the re- 
markable chalcid-fly Pelecinella, and I find that the two are 
undoubtedly synonomous. As the Leptofoenus (1862.) antedates 
Westwood’s Pelecinella (1868), Smith’s name must take pre- 
cedence. 
These insects are now generally condeded to form a part 
of the family Cleonymidse although they constitute a very 
aberrant group represented, so far as is known, only in the 
neotropical region from Brazil to Panama
