7. trochanteratus, Holmgr. 
Tryphon rutilator, Gr. 1. E. ii. 308, varr. 1 et 2. T. trochantcratus, Holmer.

Shining, punctate and black with the mouth, clypeus and face flavous. 
Differing from 7. rufi/a/or in having the:—Frons mutic, very obsoletely 
carinulate and not at all striate; metanotum with costulae entire and 
areola subelongate; abdomen black with segments two to four alone red, 
and the anal ones white-margined; basal segment apically only some- 
what smooth, with carinae extending to a little beyond its centre; apices 
of coxae, whole of trochanters and base of hind tibiae, stramineous or 
testaceous. Length, 8—1o0 mm. 
This species is extremely like 7. rufi/afor and is probably no more than 
a variety; but with the frons although coarsely and deeply punctate-rugose 
not striate, the metanotal costulae entire, anterior femora red, the hind 
trochanters always entirely pale, and anus at least subnigrescent. 
Its distribution is probably as wide as that of Z. rufilafor, though only 
recorded on the Continent from Sweden, Germany, Holland and France; 
with us it appears to be even broader, though rarer—my twenty-three 
specimens and other records show a distribution through Hampshire 
(Adams), Sussex (Bloomfield), Surrey (Capron), Kent (E. Saunders), Lon- 
don (Brunetti), Suffolk (Tuck), Norfolk (Bridgman), Devon (Parfitt and 
Marshall), Cornwall (Marquand), to Loo Bridge in Co. Kerry and Nairn 
(Yerbury), Bishopston (Dalglish), Skene (Elliott), Aberdeen (Bloomfield), 
Rannoch and Govilon in South Wales (Marshall). It appears to be 
abroad longer than 7. rufi/afor, since I possess specimens taken by 
Saunders at Dover in May, 1872, and in Scotland on 7th August, 1909, 
by Elliott. But that it is distinct from that species I cannot credit, since 
I have invariably taken them together, often upon the same flower-table 
of Heracleum, upon which it has invariably occurred to me at Moulton, 
Barham (misnamed 7° rufilator at E. M. M. 1897, p. 267), Bramford and 
Monk’s Soham, in Suffolk.

Shining, punctulate and black, with mouth and apex of clypeus pale ; 
frons rugosely punctate and very obsoletely sulcate centrally. Antennae 
flavidous beneath; metanotal areae complete, with the areola elongate 
and apically subdilated. Abdomen red with only the first segment black; 
basal segment somewhat narrow, with its apical margin nearly smooth 
and carinae extending a little beyond its centre. Legs red, with the 
tibiae externally paler, and hind legs mainly black. Length, 8—11 mm.
