S. Celebes : Bua Kraeng, 5000 feet (taken by Fruhstorfer 

 in 1896 : type in coll. mea) (cm., B.M. Mus. Berol.). 



Easy to recognize by the long sinuous forceps and generic 

 characters. 



2. Nesogaster loallacei, sp. n. 



Statura parva ; N. doJicho, Burr, vicinus ; ab eo diffort statura 

 minore, capita rubro, elytris angulo postico interno rotundato, 

 forcipis bracchiis S brevioribus, deute uuo valido acuto armatis. 



Long. cor])oris 4*75 mm.

Celebes {Wallace). 



The type ot" this species is a unique male in tlie Hope 

 Museum, Oxford ; it was taken in ihe Celebes by Wallace in 

 1861; it is labelled in blue paper, in what appears to be 

 Westwood's handwriting, " Celebes, Wallace, Dr. Dohrn, 

 1861." 



It closely resembles N. dolichus, also from the Celebes, but 

 difTers in the points mentioned above. 



3. Nesogaster tristis (Bormans). 



Labia tristis, Borm. apud Burr, 1903, Ann. & Mag. Nat. Hist. (7) xi. 

 p. 240. 



New Caledonia. 



I have not examined a specimen of this species; but 

 de Bormans's description, together with a sketch in my 

 {)ossession, leaves no doubt whatever that it is referable to 

 this genus. It is apparently allied to N. dolichus.
