combined length of the second and tliird joints of the 

 llaLTcllnm. Pronotum sunk a little bdow the mesonotum, no 

 liigher iii the middle than at the sides, the dorsal surface 

 almost linear, very sharply sloped anteriorly. Thorax very 

 closely punctured, the pleurte covered with short silver- white 

 ])ubescence. Median segment longer than the mesonotum, 

 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 

 interrupted apical band of wliite pubescence ; pygidial area 

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

 tured. Anterior tibife 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 uervure and the first 

 transverse cubital nervure.

This is tlie Australian representative of L. mansueta^ Sm., 

 a New Guinea species. 



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

 I identified tiiis species erroneously as Larrada nigripes, 

 Sauss., ;ind treated Larra psilocera, Kohl, as a synonym. 

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

 collection, applies the name tiigripes to quite a different 

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

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

 female, whereas the specimen mentioned by Schuiz is a male 

 and not headless. But Saussure's description is insufficient 

 for any certainty. With regard to L. psilocera^ Kohl, the 

 description of tiie antennge 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 that 

 the specimen may have come from one of the Austro- 

 Malayan or Melanesiau islands.
