elevated apex being easily seen when the face is looted at from the side ; in Wesmaeli 

 the mesonotura is much more largely, closely, and deeply punctured, the post- 

 scutellum is dull, closely and rugosely punctured, and the clypeus in the ? is neither 

 raised nor produced, but has its apical margin deeply emarginate, the vertex of its 

 head is also more quadrate than that of Shuchardi. 

 Aepacttts, Panz., Gorttes, Latr., Hoplistjs, Lep. 



Following the views of Handlirsch (Monogr. der mit Nysson und Bembex, 

 verwandten Grrabwespen), Arpactus and Soplisus should be treated as sub-genera 

 of Oorytes. 

 Cerceeis emaeghnata, Panz. (sabulosa, S , Shuck., Saund., Synopsis, Smith?). 



This species was introduced into our list by F. Smith, Ent. Ann., 1861, p. 43, 

 on a specimen he captured at Kingsdown, near Deal, but he omitted it from his 

 Catalogue published by the Entomological Society, and so it escaped my attention, 

 and I have not recorded it either in my Synopsis or Catalogues. Dr. Mason has 

 kindly sent me the original specimen to examine, it is labelled " Kingsdown," and is 

 undoubtedly referable to this species ; the <? specimen standing in Shuckard's col- 

 lection under sabulosa is also referable to emarginata, and this has served for the 

 description of sabulosa, <? , in his " Fossorial Hymenoptera," in my Synopsis, and, I 

 think, also in Smith's " Fossorial Hymenoptera ;" the species is really very distinct, 

 as the second ventral abdominal segment is semicircularly raised at the base ; the 

 only other British species in which this character exists is ornata, Schafp., which may 

 be known at once from emarginata by the shining basal area of its propodeum, 

 which, in emarginata, is dull and deeply striated. 



C. QXTADRiciNCTA, Panz. (sABULOSA, Smith, ? , Saund., &c.). 



I adopt this name in compliance with the views of Schletterer (Die Hym. Gatt., 

 Cerceris, Latr., &c.). 



CrABRO 1ITURATT7S, Panz. (KoLLAEi, Dahlb.). 



Panzer's name is the oldest, and should, therefore, be retained. Vestitus, Smith, 

 is the cJ of this species. 



Vespa atjstriaca, Panz. (aeborea. Smith). 



It is only lately that I have had a copy of Andre's Hymenopteres d'Europe, &c., 

 in my hands ; in this he treats arborea, Smith, as a variety of the above, and I feel 

 no doubt that he is correct ; the continental specimens of austriaca, which I have 

 seen, are much darker than ours, and it never occurred to me that the two species 

 could be identical ; still, I can find no structural character to distinguish them apart, 

 and the mere matter of colour is hardly important in a genus where colour varies 

 so much in most of its species. The $ and $ only of austriaca are known, and it 

 is suggested that it may be an inquiline on other wasps, as Psithyrus is on JBombus. 

 The remark of F. Smith, Cat. Brit. Foss. Hym., &c., 1858, p. 219, " First discovered 

 by myself in 1836, near Wakefield, Yorkshire, building nests in fir trees," at first 

 sight seems to be against this theory, but an inquiline might be laying its eggs in the 

 nest of the other wasp, and so apparently be its rightful owner, and give the idea 

 that it was building the nest. I am very glad to think that this species has now in 

 all probability found its proper position.
