46 THE ENTOMOLOGIST. 
propodeum, but is markedly distinct in other ways, the ¢ 
having the abdomen almost black or deep plum-colour--an 
exaggeration of the black discal spot so characteristic of ¢ 
sabulosa. Also both sexes are of the same size, neither being 
so large as the average 2 sabulosa, nor so small as some of the 
latter’s males. For the last reason campestris can generally be 
distinguished on the wing. 
Psammophila hirsuta: This fine thing did not appear this year 
until both of the former were almost over, i.e. towards the 
middle of September. Locally common. My last capture was 
made in the first week of October, and several females were seen 
later at Setley. : 
Psammophila lutaria was not seen on the coast here at the 
end of August, but might have been taken afterwards. 
Pemphredon: Members of this family were scarce, and as 
most of the trunks and palings in the forest were sodden with 
rain I did not take a single P. lugubris or black crabro. 
Diodontus : Once seen ; probably tristis. 
Mimesa: Only two specimens, which are probably bicolor. 
They were picked out from mixed wasps collected for me and 
pinned before determination, so that markings on mesonotum are 
difficult to make out. 
Gorytes mystaceus (Royden) and Hoplisus laticinctus (Royden) : 
A fine 2 of the latter in July flying over a tangled mass of 
brambles, heather, ete. Wet weather spoiled the search for this 
species and Nysson, of which family none were seen. 
Mellinus arvensis: Extremely abundant locally. At Setley it 
occurs in one gravel-pit commonly, but not once seem in another 
close by! Preys here on various T'achinide (Diptera) ; on several 
occasions taken with the bright green Pseudopyrellia cornecina. 
Females are very fond of resting on leaves, especially bracken, 
probably in search of flies. 
M. sabulosus I did not see on the coast here between Milford 
and Highcliffe. 
Cerceris ornata occurred singly at places widely apart. 
C. labiata and C. interruptus both taken, but the fine C. arenaria 
not even seen. 
Oxybelus uniglumis: Setley and elsewhere, but not common. 
Crabro: As referred to under Pemphredon, I did not take 
any of the ‘‘black’’ species. C. quadrimaculata was not seen on 
any dead trunks, old posts, ete. The same may be said of 
C. dimidiatus, although both no doubt were present. 
C. cephalotes, C. chrysostomus (Royden in September) ; a single 
? C. cribrarius from G. Gulliver; C. peltarius (females not 
uncommon on banks at Norley Wood and singly elsewhere). 
C. lituratus: One g at Royden. C. albilabris did not appear. 
Vespa: V.crabro not nearly so common as last year, and 
entirely absent at Royden, where the previous autumn it swarmed
