Prionus.) LONGICORNIA. 219 
lum rounded behind ; elytra broad, rugosely punctured, with obsolete 
traces of raised lines, indistinctly mueronate at sutural angles; legs 
rather long and stout, femora and tibizw compressed. lL. 25-38 mm. 
Male with the antenne distinctly 12-jointed, longer, more robust, 
and more strongly serrate, abdomen pubescent, fifth segment depressed 
and slightly emarginate at apex. 
Female with the antenne 11-jointed, the last joint being obsoletely 
3-jointed, shorter and less strongly serrate, abdomen glabrous, fifth seg- 
ment very slightly emarginate at apex. ' 
In decaying trees ; on fennel, &c. ; occasionally taken on the wing ; local, and asa rule 
not common, but occasionally abundant; Richmond Park, Oakland Park, Coombe 
Wood, Sevenoaks, Haslemere, Belvedere, Tonbridge; Windsor Forest * ; Loughton, 
Essex ; Colchester ; Cambridge ; Hertford; Shipley, near Horsham ; Hastings; Folke- 
stone; Arundel, once in abundance in an old tree (S. Stevens) ; New Forest; Devon 
(not uncommon at the roots of old oaks in winter) ; Swansea; Llangollen ; Aston, near 
Birmingham ; Cannock Chase ; Dunham Park and Stretford, near Manchester. The 
Rev. C. T. Cruttwell informs me that he found the species flying in swarms on a 
hot damp evening early in July, 1873, on the edges of Shotter Mill Wood, near 
Haslemere ; he did not see any flying on any other evening, but on that occasion 
they were as numerous as cockchafers in early summer. Mr. Parfit records the 
capture of a female which contained 162 eggs, which filled the entire abdomen; 
these eggs are somewhat cylindrical, but taper slightly towards one end; they are 
rather thickly punctured all over with two sets of punctures, the interstices between 
the larger being filled with minute punctures, the whole being smooth and somewhat 
polished ; their length is from 3} to 4 mm. 
CERAMBYCIDA., 
This family contains a very large number of genera and species, which 
are distinguished from the Prionide by not having the thorax margined 
or the prosternum produced behind the anterior cox, and by the free 
and distinct labrum; from the Lamiide they may be known by not 
having the tibiz grooved on their inner side, and, as a rule, by having 
the last joint of the palpi truncate and never acute at the tip; the family 
is by some authors separated from the Lepturide, but it seems the best 
course to regard the Cerambycina and Lepturina as tribes of one family ; 
by many authors the term Cerambycide is apphed to the whole group 
of the Longicornia. In the last European catalogue, Heyden, Reitter, and 
Weise adopt this plan, and divide the group into two series, the Anau- 
lacnemite (containing the Parandrini, Spondylint, Prionini, Lepturini, 
and Cerambycint) and the Metaulaenemite (containing the Lamiini) ; 
this appears, however, to be only carrying the distinction of the grooved 
tibiz a little further, and it is hardly worth while to upset the old 
arrangement. The Cerambycide, as arranged in this work, are repre- 
sented in Europe by considerably more species than the Lamiide; the 
two tribes may be distinguished as follows: the differences, however, 
are not very striking in many cases :— 
* Mr, J. C. Bowring has taken several specimens this summer (1889) in this 
locality, all of which ‘* emerged from roots of oak trees running along the ground, 
leaving holes like those of bees’ nests.”
