outer, a bifid mark, broad and rounded on the inner, longer and 

 narrower on the outer sides on the apex of the first abdominal segment, 

 and narrow lines all round the apices of the second to fifth abdominal

The narrowed basal part of the abdominal petiole is about one- 

 fourth of the whole ; it becomes gradually thickened above and 

 laterally ; the apex is depressed above ; the narrowed base of the 

 second is a little more than one-fourth of the whole. The first and 

 second are impunctate, except the apex of the latter, where there is a 

 punctured belt. The third, fourth, and fifth segments are strongly 

 punctured. The pronotal crest is conspicuous, and extends almost 

 half-way down the sides. Mesonotum and scutellums smooth, shining, 

 except the part at base of scutellum, which is strongly striated. Centre 

 of metanotum strongly striated, the top lateral angles as strongly, 

 obliquely striated, the stria? twisted ; there is a stout keel down its 

 centre. Mesopleura? strongly, closely punctured, the pro- and meta- 

 pleurse smooth. Front and vertex rather strongly and closely punc- 

 tured ; the ocelli in a triangle, the hinder separated from each other 

 by a greater distance than they are from the eyes ; they are placed 

 opposite the end of the eyes. Clypeus rounded, its apex broad, 

 clearly separated, transverse, smooth, shining, the shining part broader 

 in the middle. Temples roundly, obliquely narrowed. There is a 

 stout keel down the basal half of the mesonotum, it being bordered by 

 a shorter, thinner one on the base. The four anterior tibia? are yellow 

 in front, and there is a narrow yellow line on the outer edge of the 

 hinder ; the apex of fore femora narrowly, of the middle more broadly, 

 yellow. Mandibles with two broad apical teeth. Scutellum flat. The 

 second lamina of second abdominal segment is narrow, distinctly re- 

 flexed. The post- scutellum becomes gradually narrowed towards the apex.

NOTES AND OBSERVATIONS. 



The Entomological Club. — A meeting of this old-established Club 

 was held on January 22nd last, in the Entomological Salon, Holborn 

 Restaurant. Mr. G. H. Verrall in the chair. Members and invited 

 guests began to assemble soon after 6.30 p.m., and by 8.30 p.m. — at 

 which time supper was served — there were over seventy present. 

 Supper being over, Mr. Verrall first proposed the toast of " The King," 

 and afterwards that of " The Entomological Club." In moving the 

 latter, he adverted to the fact that having been elected a member of 

 the Club in 1887, it was the twenty-first occasion on which it had 

 been his privilege and pleasure to occupy the chair. He also 

 remarked that although membership of the Club was limited to eight, 

 still they could elect honorary members, and that these would be 

 eligible in their turn to fill up such vacancies as might occur on the
