168 Insects, 



common as Vespa vulgaris, but is scattered all over the country ; I 

 have taken it in Yorkshire. I have observed that its nests are smaller 

 than those of V. vulgaris, and its societies less numerous in individuals. 



Section II. — Tree Wasps. 

 Scape of the Antenna yellow in front in all the Sexes. 



Sp. 4. Vespa holsatica, Linn, and Fab. 

 Vespa Anglica, Leach. TJie Campamilar Wasp, Bingley. 



Female. — Length 9 lines. Head black ; clypeus yellow, with ge- 

 nerally a minute black dot in the centre ; scape of the antenna? in 

 front, a line close to the inner, another on the upper part of the outer 

 margin of the eyes, yellow ; mandibles yellow, their inner margin black. 

 Thorax black ; a line from the tegulse (which are black, having some- 

 times a small yellow dot), a spot under the wings and two on the scu- 

 tellura, yellow ; the third submarginal cell in the wings of this and 

 the following species is widest towards the marginal cell ; legs yellow, 

 * the thighs black, yellow at their 



apex, a black spot generally be- 

 hind on the anterior tibiae, termi- 

 nal joints of the tarsi feiTuginous. 

 The abdomen has a black band 

 at the base of all the segments, 

 that on the second is widest and 

 tridentate, the following are ge- 

 nerally unidentate, the third also 

 is sometimes tridentate. 



Tlie Neuter exactly corresponds 

 with the female. Length 6 lines. 



Vespa holsatica. k male. I female, m neuter. Tlie Male haS the anteunSB fili- 



form, proportionably stouter than in V. vulgaris ; in other respects, 

 and in colouring, it corresponds with the other sexes, except that the 

 abdominal bands are not so frequently dentate. Length 6 — 7 lines. 



Linnaeus appears to have drawn up his description from a specimen 

 of the neuter, and he says " half the size of V. vulgaris." 



Although I consider this species essentially a tree-wasp, still it 

 sometimes constructs its nest in banks in the West of England. A 

 friend of mine collected some tree-wasps for me in his garden in York- 

 shire, and they consisted principally of V. holsatica; I also possess 

 a nest which 1 took out of a gooseberry-bush : still I found a nest in
