first. Mandibles rather broad, striated ; their terminal edge long 

 sharp, with a pointed tooth at the end and an obtuse one at its posterior 

 third. Clypeus very triangularly advanced, nearly acuminated, strongly 

 carinate, longitudinally striated. Laminae frontales extremely short ; 

 sulcus frontalis broad and short. The sides and the anterior part of the 

 head longtudinally striated. Vertex and occiput shining, nearly smooth. 

 Mesothorax strongly strangulated after the mesonotum ; the strangula- 

 tion much widened. Mesonotum small and narrow. The basal surface 

 of the metanotum narrow, rounded, as long as the pronotum and the 

 mesonotum together. The declivous one moderately short, transversely 

 wrinkled, rounded at the sides and above. The rest of the thorax is 

 shining and nearly smooth, except the sides of the mesothorax and of the 

 metathorax, which are more or less rugose. Scale raised, narrowed in 

 front, smooth and shining, as long as the breadth of its posterior sur- 

 face. Abdomen shining and nearly smooth, strongly strangulated after 

 the first segment. 



Here and there a few erect hairs on the legs, the scapi, and the under 

 side of the body. Applied pubescence nearly totally wanting. Yellow- 

 ish or reddish brown, darker over the head, the thorax, and the scale. 

 Funiculi, tibise, and tarsi testaceous. Sibsagar. 



N. B.— Smith (Trans. Ent. Soc. Lond. 1876, Fart IV, 6 Sept.) de- 

 scribes a Ponera castanea from New Zealand and says that the genus 

 Ponera had not been previously ascertained to inhabit New Zealand. 

 Now Mayr had previously (Novara Reise, Formicidae, p. 69, 1865) also 

 described a Ponera castanea (!) from Auckland (New Zealand) ; but 

 I cannot ascertain if P. castanea, Smith, and P. castanea, Mayr, are two 

 different species or not.
