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.
