on each side of the median line, this line is visible only near the 

 base. The scutellum is transversely rounded, with a small 

 depression near the apex. The elytra are very faintly punctate 

 and striate, and leave the pygidium exposed. The fore tibiae are 

 armed externally with five teeth, the spur on the inner apex is 

 only slightly securiform, being very much narrower than in many 

 of the genus ; the mesosternal point is obtuse and not prominent. 



Length, 6 lines. 



One specimen (a male) is all I have ever seen of this species. I 

 received it some years ago in a collection from South A ustralia. 



In the Annales Musco civico of Genoa for the year 1875, p. 999, 

 Dr. Gestro describes under the name of Neolamprima a genus 

 differing only from Lamjjrima in the very remarkable form of the 

 mandibles of the male. The species on which he forms the genus 

 is from Arfak on the North-west part of New Guinea and he names 

 it Ncolamprina Adolphinae I have lately received from the 

 Herbert District, Queensland, a specimen of the genus, and I think 

 a distinct species. 



Neolamprina mandibularis. n. sp. 



Male. In colour and form of body much like Lamprima aurafa. 

 The thorax very thinly and minutely punctured, the elytra smooth. 

 The mandibles are very long, (more than half the length of the 

 insect) slightly narrower in the middle than at the base, widening 

 again a little at the apex, which is tx'identate, without notch or 

 tooth on the upper surface, curving upwards from the middle, 

 densely bearded on the inner surface, and serrated on the lower 

 edge from a little below the middle to the apex ; the teeth forming 

 the serration being regular, truncate — resembling the cogs of a 

 wheel — and eight in number. The mesosternum is acutely pointed. 

 The fore tibiae are strongly six-toothed on the outer side, the inner 

 spur is strongly securiform. 



Length, without mandibles 10 lines.
