214 SERRICORNIA. | Ennearthron. 
deeply emarginate in front, and produced into a small sharp horn at 
each side of the emargination ; the thorax also is broader than in the 
female. 
In fungoid growth on trees; local, and, as a rule, not common; Caterham, Rich- 
mond Park, Esher, Chatham, Sheerness, Hawkhurst, Darenth Wood, Highgate, 
Chertsey, Loughton, West Wickham (where Mr. T. Wood has taken it commonly) ; 
Hastings; St. Leonard’s Forest ; New Forest ; Robins Wood, near Repton, Burton-on- 
Trent ; Dunham Park, Manchester. 
OCTOTEMNWS, Melli¢é. (Ovrophius, Redtenbacher.) 
This genus, if we include under it the species of Orophius, which 
appears only to differ from it materially in its largely developed and 
prolonged mandibles, contaius three or four species, which oceur in 
Europe, Madeira, and Japan; they are distinguished by their 8- 
jointed antenne, of which the first two joints are large, the third elon- 
gate and slender, the fourth and fifth small, the last three being dilated 
and forming a well-marked club; the anterior tibie are also finely 
denticulate or spinose externally for their whole length; our single 
species is very shining, almost glabrous, and very finely and more or 
less obsoletely punctured ; it is one of the commonest of our species of 
Cissidee. 
O. glabriculus, Gyll. A small, short, convex species, with the 
sides somewhat rounded, glabrous and shining, of a lighter or darker 
castaneous brown colour; head finely punctured, with the mandibles 
slightly projecting, unequal, the left one being larger than the right ; 
antenne yellow; thorax as long as broad, narrowed in front, very finely 
punctured, with the angles rounded ; elytra very convex and shining, 
with fine and somewhat rugose punctuation, which is, however, stronger 
than that of thorax, and with a fine sutural stria ; legs yellow. L. 
1-1} mm. 
In boleti on old stumps, &c.; common and generally distributed throughout the 
greater part of England and Wales and Ireland; Scotland, in Polypori, local, Forth 
and Moray districts. 
The species much resembles Cis nitidus in general appearance, but 
may easily be known (apart from the 8-jointed antenne) by the shape 
of the thorax which is distinctly narrowed in front, and by the finer 
sculpture of the elytra. 
LONGICORNIA. 
This group is one of the largest and most important of the whole of 
the Coleoptera; in the Munich catalogue, published in 1872-73, some 
hundreds of genera and upwards of eight thousand species are enume- 
rated, and the supplement published by M. Lameere in 1883 contains 
the names of two hundred new genera and fourteen hundred new species,
