474 MR. R. E. TURNER ON [May 12, 



Larra scelesta, sp. n. 



2 . Clypeus very finely and closely punctured, the anterior 

 margin shining and very slightly and broadly rounded. Mandibles 

 strongly notched on the outer margin, very blunt at the apex, 

 with a fringe of short stiff hairs on the outer margin. Antennae 

 inserted nearly as far from each other as from the eyes ; the 

 second joint of the fiagellum only a little more than half as long 

 again as the first, the third intermediate in length between the 

 first and second. Eyes separated on the vertex by a distance not 

 quite half as gTeat again as the length of the second joint of the 

 fiagellum. Labrum bilobed. Front smooth and shining, with a 

 longitudinal furrow on each side, the anterior ocellus lying in a 

 broad and shallow transverse depression ; the posterior ocelli very 

 indistinct, with an irregular, shining, transverse depression behind 

 them ; the vertex minutely j^unctured. Thorax veiy finelj^ and 

 closely punctured, the pronotum longer and less abruptly depressed 

 than in L. nigri2)es Sauss. Median segment much longer than 

 the mesonotum, longer than in L. nigrijjes, finely rugose, with a 

 carina from the base to the apex, most strongly marked at the 

 base, vertically truncate posteriorly, the face of the truncation 

 finely rugulose, with a median sulcus. Abdomen shining, very 

 shallowl}' and minutely punctured, the three basal segments with 

 a band of white pubescence on the sides ; the pygidial area 

 broadly triangular, rather sparsely but deeply punctui'ed. Anterior 

 tibiae without spines. The second cubital cell is as long as the 

 third on the radial nervure ; the third is nearly three times as 

 long on the cubital as on the radial nervure, the third transverse 

 cubital is oblique and almost straight. 



Black ; the mandibles and the spines of the tibiae fusco-ferru- 

 ginous ; tegulse testaceous. Wings f usco-hyaline, faintly iridescent ; 

 nervures black. 



Length 14 mm.

Difi"ers from L. nigrijies in the shorter antennae with diflferently 

 proportioned joints, in the much closer approach of the eyes on 

 the vertex, the longer pronotum and median segment, and the 

 broader pygidium. The pronotum and abdomen difier markedly 

 from those of L. australis, with which it agrees in the smooth 

 anterior tibiae, which are heavily spined in L. nigri2)es.

If my identification of this species is correct it is a Larra.

5 . Clypeus very broadly truncate at the apex, oi^aque and 

 almost smooth, with a row of large punctures before the apical
