Toxotus. | LONGICORNIA. 233 
Britain ; it is a large and conspicuous insect, and may be known by the 
large tubercle at the sides of thorax and the short fourth joint of the 
antenne ; the antenne are almost approximate, and inserted at some little 
distance from the eyes, which are very slightly emarginate ; the elytra are 
gradually and strongly narrowed from base to apex ; the anterior coxal 
cavities are open behind ; the legs and antenne are long and slender; 
like most of the other members of the tribe, it is found in June 
and July on Umbellifere; the larva is found in stumps of deciduous 
trees. 
T. meridianus, Panz. (chrysogaster, Schrank.). A conspicuous 
species, very variable in size, with the head and thorax much narrower 
than the elytra, and the elytra considerably narrowed behind ; colour 
variable, the head and thorax being always black, and the elytra entirely 
black or entirely rufo-testaceous, or with the apex broadly and the 
suture black and the rest testaceous, or with the base only testaceous ; 
under-side black clothed with silvery pubescence, or testaceous clothed 
with golden pubescence; antenne and legs black in black specimens, 
and more or less red in those that have the elytra rufo-testaceous ; 
thorax oblong, with a central channel, furnished at sides with a strong 
tubercle but not spined, dise uneven; scutellum black; elytra with 
well-marked shoulders, very finely sculptured, with obsolete raised 
lines; legs long, with strong tibial spurs. L. 15-24 mm. 
Male smaller, with the elytra more attenuated to apex, and the 
antenne longer than in female, and with the fifth segment of the 
abdomen subtruncate at apex ; in the female this segment is sinuate on 
both sides, and longitudinally impressed in the middle. 
On flowers, especially Umbellifere, in woods; often flying in the hot sunshine ; 
somewhat local, but generally distributed and common from the Midlands south- 
wards; rarer further north ; Northumberland and Durham district, not common ; 
not recorded from Scotland. 
PACHYTA, Serville. 
The British members of this genus are known from the preceding by 
having no distinet tubercle at the sides of the thorax, and by the fact 
that the third and fourth joints of the tarsi are nearly equal; they are 
also smaller and more robust-looking insects ; as ordinarily constituted 
the genus contains about seventy species, which are all found in Europe, 
North America, and North and Central Asia; the constitution of the 
genus has, however, been much altered by modern authors. In the last 
European catalogue the genus Pachyta contains only two species, neither 
of which are found in Britain, and of our three species two are referred 
to Leptura and one to Acmcops. 
I. Eyes slightly emarginate ; thorax black ; elytra 
yellow with black markings, or black with yellow 
markings.
