250 LONGICORNIA. | Mesosa. 
MESOSA, Serville. 
This genus contains a dozen species, which are widely distributed ; 
three are found in Europe, and the remainder have been described from 
China, Japan, Ceylon, Thibet, the Amazon district, &e.; they are broad 
and robust insects, and may be distinguished from all the preceding g genera 
of the tribe, to some of which they bear a rather close resemblance, by 
the fact that the thorax has no lateral spines ; the forehead is excavated 
between the antenne, and the antenne are long and pilose beneath ; the 
prosternal process nearly reaches the apex of the anterior cox, the 
cavities of which are narrowly closed behind; the mesosternum is 
prominent in a blunt tubercle between the intermediate coxe ; the legs 
are moderately long and robust; the larva of M. nubila is found in 
decaying logs of poplar, lime, beech, &c.; it appears closely to resemble 
that of Pogonochwrus, having the prothorax a third broader than the 
eighth segment of the abdomen, and the anal segment trifurcate; the 
patterns of the tubercular or scansorial areas of the abdominal segments 
of various species of Longicorns vary very much, and afford good 
characters for their distinction ; ; they are, however, hard to describe ; 
those of M. nubsla and P. pilosus will be found ficured by Schiddte, 
Pars ix., Tab. xvii., figs. 20 and 16 respectively, and many others will be 
found figured by Schiddte and Chapuis and Candéze in their works on 
the larvee. 
M. nubila, Ol. (ncbulosa, F.). Short, broad and robust, rather 
convex, black, variegated with black, brownish-ferruginous and white 
pubescence ; head large, together with thorax marked with longitudinal 
lines of pubescence, antennze longer in male than in female; thorax 
transverse, without spines at sides, coarsely and sparingly punctured ; 
elytra broad, sparingly and closely punctured, with a broad common 
waved whitish or whitish-brown fascia about middle, bounded above 
and below by a narrow dark line, that on the posterior margin being 
strongly dentate ; legs pilose, variegated. L. 9-13 mm, 
In decaying boughs; rare; most of our specimens have been taken in the New 
Forest ; while I was collecting with Dr. Sharp and Mr. Gorham in that locality on 
May Ist, 1885, Mr. Gorham took two specimens from a small bough lying on the 
ground. Monks Wood (not uncommon); Cambridge; Stephens also records it from 
Coombe Wood, Windsor, and Bewdley Forest. 
AGAPANTHIA, Serville. 
This genus may be easily known by its elongate form, taken in 
conjunction with its 12-jointed antenne, which are longer than the 
body; the mandibles are bifid at apex; the thorax is not spined at 
the sides, and the anterior coxal cavities are closed behind, the cox 
themselves being slightly separated ; the intermediate tibiew are slightly 
sinuate externally towards apex, and the tarsi are long, being almost as 
o) 
long as the tibize ; the number of species at present known is about thirty,
