T imagine that the moth might be taken without diffi- 
culty at night in September, which appears never to 
have been attempted. It is not rare at Noguera and 
Bronchales. I believe Prof. Korb obtained over 
200 caterpillars last year, but did not meet with much 
success in rearing them. Another very rare insect, 
peculiar to the Albarracin, is Bombyx (or Albarracina) 
korbi, Staud., discovered by Prof. Korb in 1881, very 
rare at Albarracin and unknown elsewhere in Europe. 
Canon Zapater’s list of moths is long and interesting ; 
but these do not come within the scope of this paper. 
XX. New or little-known Sphegide from Hgupt—a 
Correction. By the Rev. F. D. Moricz, M.A., 
F.E.S. 
In my paper, published in these Transactions (1897, 
pp. 310-316), I unfortunately described one of the new 
species under the name of Tachysphew (?) integer (p. 308). 
‘This name is not available, having been applied by Kohl 
to another species (Ann. Hofm. Wien, vii., p. 216, 1892). 
I propose therefore to call my insect, instead, Tachysphex 
(?) hologuathus—this name referring (as my former 
name was intended to do) to the entire mandibles, which 
form so striking a characteristic of the insect in contrast 
with the notched mandibles of cther species belonging 
to the same genus.
