( 443 ) XIX. Descriptions of neiv species of Scoliidse in the collection of the British Museum, u-ith occasional reference to species already known. By W. F. Kirby, F.E.S., Assistant in the Zoological Department, British Museum. [Read July 3rd, 1889.] Plate XV. In rearranging the collection of Scoliidce in the British Museum I have met with several interesting new species, which I describe in the present paper. The Scoliida are an interesting group, and, as a rule, not specially difficult, and it is singular that almost nothing has been done in this family since the catalogue (or more properly, monograph) published by Saussure and Sichel in 1864. Their genera are very easily recognisable, and therefore I have retained them provisionally, although they are founded too exclusively on neuration, and therefore sometimes separate closely-allied species, and in some few cases would lead to sexes or varieties of one species being placed in different genera. The present paper relates only to the typical genera of Scoliidce included in Saussure and Sichel's monograph, which, af'ter fixing the types and weighing the claims of the various names to priority, should stand as follows : — 1. Liacos, Guer. (= Triliacos, S. & S.). 2. Diliacos, S. & S. 3. Scolia, F. (= Triscolia, S. & S.). 4. Discolia, S. & S. 6. Elis,F. {=Trielis, S. & S.). 6. Campsomcris, St. Farg. {=Colpa, St. Farg.,=: Dielis, S. & S.). I have not included the doubtful genera Cosila and Epomidioptn-on, which hardly belong to the restricted family Scoliidce, in the present paper ; nor two genera, likewise of doubtful position, described since the mono-graph, viz. Pseudoscolia, Bad., and Dyscolesthes, Westw., which the Museum does not at present possess. TRANS. ENT. SOC. LOND. 1889. PART III. (OCT.; 2 H
