ACULEATE HYMENOPTERA IN YORKSHIRE. 
Corrections and Additions. 
ROSSE BUTTERFIELD, F.E.S., AND W. J. FORDHAM, M.R.C.S. 
Since the manuscript of this list was completed, there have been no 
additions to the county list but there are a few additional localities to 
record and a few corrections. 
1. Elampus auratus L. (Nat., 1930, 363), 64 M.W. Roundhay, 28/6/25, 
with a Pemphredon (? lethifer Shuck) A.E.B. 
2. Chrysis ruddii Shuck (Nat., 1930, 364), 64 M.W. Bardsley, 7/6/12, 
on a sandy bank with Halictus rubi-cundus Chr. A.E.B. 
(Mr. Bradley „ has not taken Chrysis ignita L. near Leeds.) 
3. Ancistrocerus antilope Panz. (Nat., 1930, 366), 64 M.W. Shadwell, 
18/5/12, a $ on a sunny bank at pondside. J. C. Hesselgrave. 
4. Priscnemis pusillus Schiodte (Nat., 1930, 368), 64 M.W. Roundhay,. 
6/8/19, 99 dragging a small, elongated, flesh-coloured spider. 
A.E.B. 
5. Priscnemis schiodtei Haupt. ; recently separated from pusillus, 
occurs in Notts, and should occur in Yorkshire. 
6. Priscnemis gracilis Haupt. also separated from pusillus, may possibly 
occur on the Yorks, coast. 
7. Psammochares approximatus Sm. The record under nigerrimus Scop. 
from Collingham, 1919 (A.E.B.), refers to this species. 
8. Psammochares pectinipes Anct. Brit. (Nat., 1930, 369), now called 
campestris on the Continent, is inquiline on other Psammocharidae 
like other members of its group. 
9. Astatus stigma Panz. (Nat., 1930, 369), 61 S.E. Allerthorpe,. 
31/7/28, 31/7/31 , 2 W.J.F. (see Nat., 1931, 174). 
Its parasite Hedychridium integrum Dhlb., has not yet been taken 
in Yorks. 
10. Nysson spinosus F. (Nat., 1931, 156), stated in error to be parasitic 
on Gorytes and Arpactus. This is a definite parasite of Gorytes 
mystaceus but does not attack the closely allied campestris which 
has N . interruptus . Arpactus is too small to be parasitised by 
spinosus and has its own parasite N. dimidiatus. 
11. Metacrabro lituratus Pz. (Nat., 1931, 156). During the last thirty 
years has become<very general in the southern counties, often as 
in Devon, extremely common locally. 
12. Crossocerus anxius Wesm. (Nat., 1931, 157). Breeding in bramble 
stems is unusual (Halifax, O.G.S., 1908). It occurs numerously 
in a number of counties, always burrowing in the ground, mostly 
in vertical cuttings, generally of clay soils, but sometimes in more 
sandy soil. Colonies are frequent in hedge banks. 
61 S.E. Allerthorpe, 27/7/29, £, W.J.F. 
13. Crossocerus elongatulus V.dw. (Nat., 1931, 158). Smith’s records 
for small Crabros are doubtful. Dr. Perkins says that he had many 
elongatulus from York with black hind -legs and no yellow at 
base of tibiae. (Litt. 29/1 1/31). 
14. Colletes glutinans Env. (Nat., 1932, 235). The parasitic Diptera 
Hammomyia grisea Fin. and Milto-qramma punctatum Ing. have 
been bred from this bee, the former from Allerthorpe (Nat., 1930, 
330), the latter from Skipwith (Nat., 1932, 260). 
15. Sphecodes dimidiatus v Hag. (Nat., 1932, 236), is quite a scarce 
insect. Yorkshire appears to be its northerly limit. 
16. Halictus smeathmanellus Kirb. (Nat., 1932, 257). According to 
Dr. Perkins, Yorkshire specimens of this species are not typical 
— as also are all specimens from north of a line drawn from the 
1933 March 1
