130 Arthur M. Lea: 



fairly short (although somewhat longer than in other species 

 of Larnprima), with but one tooth on the lower surface of each. 

 In this form (which is quite a typical Lamprima) the mandibles 

 are about three-fifths of the length of the prothorax.i The 

 greatest length of the mandibles that I have seen is about twice 

 the length of the prothorax. 



Mr. H. H. D. Griffith has a specimen from Kuranda with the 

 left mandible of the normal (i.e., comparatively short) form, 

 and the right noticeably longer than the prothorax. I have a 

 similar specimen from Cairns. 



Following are given (in millimetres) some lengths of the males 

 and their mandibles, with the number of teeth on the lower 

 surface of each mandible.

The three terminal teeth also vaiy ; the one at a slight 

 distance from the apex on the upper surface is usually directed 

 straight up, but sometimes curves slightly inwards, sometimes 

 backwards and inwards, or backwards and outwards ; in two 

 specimens it is directed obliquely forwards. The median one of
