Hymenopterenfauna von Paraguay. 179 
II. On the Thynnidae and Scoliidae collected in Paraguay 
by Professor Anısıts with descriptions of other 
South American species. 
By 
Rowland E. Turner. 
With Plate 11. 
This paper is based upon the collection: of South American 
Thynnidae in the Berlin Museum, including those collected by Prof. 
Anısırs in Paraguay. I have also added notes on some species 
received from Dr. H. v. JHERING of Säo Paulo and a few from other 
sources. Unless otherwise mentioned the types are in the Berlin 
Museum. 
The collection considerably extends the known range of the 
family in South America, no species having been previously described 
from Colombia. They will probably prove to be more numerous at 
high elevations than on the plains in the more tropical countries, 
only one species having been collected by Bates in the Amazon valley. 
Family Thynnidae. 
Aelurus unecifer n. Sp. 
(Pi... 21, 2Wio221e,) 
d. Clypeus very narrowly produced and deflexed at the apex, 
emarginate and depressed on each side of the produced apical portion, 
with a small tuberele on each side on the depression; smooth and 
shining at the base, sparsely punctured in the middle. Mandibles 
very broad at the base, with a small tooth on the inner margin near , 
the middle, thence sharply narrowed and bidentate at the apex. 
Head shining, finely but not very closely punctured, with a shallow 
suleus reaching from the base of the clypeus to the anterior ocellus.
