214 SERRICOUNIA. [Ewicartftron. 



deeply emarginate in front, and produced into a small sharp horn at 

 each side of the emargiuation ; the thorax also is broader than in the 

 female. 



In fungoid prowth on irees ; local, and, as a rule, not common ; Caterham, Rich- 

 mond Park, Esher, Chatham, Sheeruess, Hawkhurst, Darenth Wood, Highgatc, 

 Chertsey, Loughton, West Wickham (where Mr. T. Wood has taken it commonly) ; 

 Hastings ; St. Leonard's Forest ; New Forest ; Robins Wood, near Itepton, Burtou-ou- 

 Trent ; Dunham Park, Manchester. 



OCTOTEMNUS, Mellid. (Oroplmis, 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, contains three or four species, which occur in 

 Europe, Madeira, and Japan ; they are distinguished by their 8- 

 jointed antennae, 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 tibiae 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 

 Cissidae. 



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 ; 

 antennae 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 antennas) by the shape 

 of the thorax which is distinctly narrowed in front, and by the fa'ner 

 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,
