Trichius. | LAMELLICORNIA. 61 
the spur at apex of tibia longer, and also with the pubescence of the 
whole body longer. 
Female with the first joint of the anterior tarsi simple, the spur of 
the anterior tibiz shorter, and the pubescence of the whole body shorter. 
On flowers ; very local, and, as a rule, decidedly uncommon ; it has been recorded 
by Dr. Leach from Exeter, and by Mr, Dillwyn as taken in some numbers on umbel- 
liferous plants near Swansea (v. Steph. Il. iii. 280), and Mr. Llewellyn has con- 
firmed the latter record by taking it at Neath, South Wales; it occurs, however, 
principally in the North, and has not been recorded from any localities in England 
except those above mentioned; it is very pro able that the Welsh record must be 
referred to the succeeding species ; Scotland, local, Highlands, Tay, Dee, and Moray 
districts. Mr. Dillwyn’s note on his capture of the species at Swansea is worth pre- 
serving (Catalogue of Swansea Coleoptera, p. 31) :—* About forty of these beautiful 
insects have been taken in the neighbourhood, and I have generally seen them in 
pairs. With the exception of one pair, which I found ou a double Sweet William, 
they were all taken on umbelliferous plants, and all, or nearly all, on the flowers of 
Athusa Cynapium. It has also been taken both at Coytrahene and St. Hilary, in 
this county, by my friend the Rev. J. M. Traherne, and one was caught by my son, 
Mr. L. LI. Dillwyn.” 
According to Erichson the larva is found in decaying trunks of various 
deciduous trees, such as alders, birches, &c, He does not, however, give 
any description of it. 
T. abdominalis, Mén (gallicus, Heer. ; zonatus, Schmidt). Very 
like the preceding, but, on an average, smaller, with shorter pubescence, 
and with the sides of the abdomen almost bare; the clypeus is shorter 
and less emarginate, and the thorax is broader, with the posterior angles 
more marked ; the black fascia at base is always interrupted, and the first 
yellow band reaches the shoulder ; the intermediate tibize are less dis- 
tinctly toothed, and the male has the posterior tibie slightly clavate at 
apex. L. 9-12 mm. 
On flowers, &c. I have had four or five specimens in my collection (from the late 
E. Brown’s collection), but I have never been able to make out anything satisfactory 
with regard to their capture, nor do I know of any certain locality for the insect ; 
Mr. F. Smith introduced 7’. zonatus, Germ., as British (Zool. p. 2216 [1848 ]), but did 
not know the localities of the specimens. Mr. S. Stevens believes that his examples 
were taken in Wales. 
The following is Mr. Smith’s description of “7. zonatus, Schmidt 
(gallicus, Dej. Cat.; abdominalis, var., Schmidt, Dej. Cat.”). ‘ Male.— 
The lateral margin of the thorax immaculate, the central segment of the 
abdomen transversely striated, and having two yellow macule; the 
anterior cox have a yellow macule in front. Female.—The lateral 
margins of the thorax yellow, sometimes interrupted; the ventral 
segments immaculate. The elytra in both sexes black, having the 
suture black, with two transverse yellow fascize united to a longitudinal 
one, which reaches the angle of the shoulder; the base never has a 
transverse black band; the yellow fascia are nearly or of quite equal 
width.” In 7. fasciatus the anterior coxe in the male are not maculate, 
nor are the ventral segments, and in the female the thorax has a lateral
