14 MESSRS. R. E. TURNER AND J. WATERSTON ON THE 



apical carina, of the basal area broadly interrupted in the middle ; 

 areola smooth, the carina dividing it from the petiolar ai-ea com- 

 plete ; petiolar area smooth ; postero-intermedial area with a few 

 longitudinal strife ; external area with a few minute punctures ; 

 dentiparal area smooth in the middle, with a few punctures on 

 the sides and a minute tooth at the external apical angle; spira- 

 cular area finely punctured-rugulose ; pleural and juxta-coxal 

 areJB not divided, smooth. Petiole narrow at the apex, without 

 teeth between the base and the spiracles. Hind empodia not very 

 long, not more than two-thirds of the length of the tarsal unguis. 

 Both transverse cubital nervures somewhat oblique and longer 

 than the second abscissa of the radius, the distance between the 

 recurrent nervure and the second transveise cubital nervui-e less 

 than half as great as the length of that nervure.

Nearly allied to L. spiviferum, of which it may be the male, 

 but the colour of the antennfe and the number of antennal joints 

 difler much, also the spines on the dentiparal and external arese 

 are much more distinct in spiniferu7n. The elongate mandibles 

 are common to both.

(^ . Face much broader than long, face and clypeus sparsely 

 but not very finely punctured. Antennae 42-jointed, third joint 

 more than half as long again as the fourth, the fifth distinctly 

 shorter than the fourth, the joints as far as the sixteenth longer 

 than broad, those beyond transverse. Mesonotum with the middle 

 lobe prominent ; notauli short, but deep and crenulate ; the 

 median lobe densely punctured anteriorly, sparsely postei-iorly ;
