208 Mr. Edward Saunders on Rymcnoptcra acuUata 



renders determination doubtful, and as it would be dan- 

 gerous to remove specimens of this age I have not at- 

 tempted to found any new species on them. At the same 

 time there is a bronzy Halidus which I think will prove 

 to be new, and also a $ Frosopis entirely black with the 

 exception of the yellow facial spots; it is larger than the 

 species described here and stands in the collection with a 

 label under it in F. Smith's handwriting — n. sp. ? allied to 

 signata. It is represented by a single specimen only and 

 is not referable to any species I know. 



In spite of the poor condition of Wollaston's specimens 

 it is important to record, as far as possible, the forms 

 which existed over half a century ago in an island so 

 liable to accidental immigration as Madeira. 



Professor Forel has kindly examined the ants of the 

 collection and verified those already determined by Mr. 

 F, Smith. I am indebted also to Mons. J. Vachal, who 

 has recently examined Brulle's Canary Island types in the 

 Paris Museum, for confirminGf, and in some cases correcting 

 my identifications of the Halidi. 



In Mr. Bellamy's collection is a fine series of the dark 

 form of tcrrestris mentioned above, including six females, all 

 coloured exactly like those met with by Mr. Eaton. As 

 all the specimens of both collections came from Tenerife, 

 it would be interesting to ascertain if the species has the 

 same coloration in the neighbouring islands. 



In the following list Mr. Bellamy's captures are indicated 

 by his name, the late T. V. Wollaston's by his initials, 

 while all specimens not specially indicated were taken by 

 Mr. Eaton.
