TWO YORKSHIRE WASPS. 
Chrysis ruddii Thuck and Psammochares 
approximatus Sm. 
A. E. BRADLEY. 
Dr. R. C. L. Perkins, in his valuable comments on certain 
bees and wasps recorded in Messrs. Butterfield and Fordham’s 
* Aculeate Hymenoptera in Yorkshire ’ (Naturalist, 1933, 
p. 119) indicates that Frederick Smith’s record for the Chrysis 
may possibly be open to doubt. As far as I know, my own 
record in their supplementary list (N aturalist , 1933, p. 69) 
for Bardsey, near Leeds, 7/6/14 ( not Bards/ey, 7/6/12, as 
printed), is the only other one we have for Yorkshire, so it 
seems desirable that something should be said in its justifica- 
tion. My specimen agrees perfectly with the Rev. F. D. 
Morice’s description in his ‘ Annoted Revision of the British 
Chrysididse,’ 1896. The only other Ruby Wasp with which 
it could be confused is the common C. ignita, which is also 
quadridentate behind and similar in size and dorsal colouring. 
Apart from certain less conspicuous differences, my capture 
may be recognised at once as C. ruddii by the very strong 
fiery-red reflections on the undersides of the legs. According 
to Morice, this character is never found in C. ignita. I may 
add that for many years I have been familiar with C. ruddii 
in West Carnarvonshire, where it seems to be the commoner 
of these two species. 
Dr. Perkins suggests that one Psammochares approximatus 
Sm. might possibly be P. cardui, an allied species described 
by himself in 1916. I have compared the beautifully fresh $ 
I took at Collingham (see Naturalist, 1933, p. 69) with Dr. 
Perkins’ original description of P. cardui, and also with his 
comparison of that species with its two near allies (Ent. Mon. 
Mag, 1920, p. 36) . According to these I can say with certainty 
that my specimen is not P. cardui (nor P. nigerrimus) , but 
P. approximatus Sm. I cannot speak for the one from 
Buckden, bred by Mr. Butterfield (see Naturalist, 1930, 
p. 368). 
Trioza velutina Forst. in Cumberland. — I possess a 
single Cumberland example of this rare species, taken near 
Easton in the Longtown district. It was swept in a grassy 
lane on 25/6/29. I am uncertain what plant it came from, but 
saw no Bilbery near. It has already been recorded from 
another part of the county in the Ent. Mo. Mag., 1918, pp. 
114-115. I have also met with it very sparingly in Dum- 
friesshire by general sweeping. — Jas. Murray, Gretna.
