combined length of tlie second and tliird joints of the 

 flao-ellnm. Pronotum sunk a little below the mesoriotum, no 

 higher in the middle than at the sides, the dorsal snrt'nce 

 almost linear, very sharply sloped anteriorly. Thorax very 

 closely punctured, tiie pleurse covered with short silver-white 

 pubescence. Median segment longer than the mesonotura, 

 granulate, without any distinct median sulcus or carina, the 

 apical slope finely and closely punctured. Abdomen smooth 

 and shining, the first to fifth dorsal segments with a broadly 

 interru[)ted apical baud of white pul)escence ; pygidial area 

 elongate, jiointed at the apex, finely and very sparsely punc- 

 tured. Anterior tibiae with a row of spines on the outer 

 margin. Third abscissa of the radius equal to the second, 

 the recurrent nervures separated from each other on the 

 cubitus by a distance equal to nearly two-thirds of the 

 distance between the first recurrent nervure and the first 

 transverse cubital neivure.

This is the Australian representative of L. mansueta, Sm., 

 a New Guinea species. 



In a former paper (Proc. Zool. Soc. London, p. 473, 1908) 

 I identified this species erroneously as Larrada m'gripes, 

 8auss., and treated Lnrra psilocera, Kohl, as a synotiyin. 

 Schulz (Zool. Ann. p. 191, 1911), having consulted Saussure's 

 collection, applies the name 7iigripes to quite a different 

 insect, which now bears the type-label. Saussure's descrip- 

 tion, however, seems to iiave been taken from a headless 

 female, whereas ihe specimen mentioned by Schuiz is a male 

 and not headless. But Saussure/s description is insufficient 

 for any certainly. With regard to L. psilocera, Kohl, the 

 description of the antennaj does not agree either in colour or 

 form with the present species, the clypeus also is more 

 polished. The locality given is Australia, but I suspect tiiat 

 the specimen may have come from one of tiie Austro- 

 Malayan or Melanesian islands.
