Eniirely of a brownish-red, finely pubescent, the abdomen brighter coloured and rather 
shining. Head smal] ; mandibles short and slightly curved, very hairy ; face with a central 
channel extending io the front ocellus ; ecelli placed in a curved lime. Thorax very gibbous in 
front and at the scutellum. Abdomen with the peduncle nearly as broad as the following seg- 
ment, its posterior angles rounded off, its upper surface entire and slightly convex, the ventral 
portion slizhily angulated ; abdomen with the intermediate segments slightly constructed at the 
base ; anal plate with a very deep noich, the lateral processes very acute. Wings very slighily 
tinged with cinereous, more fulvous towards the costa. Stigma fulvous brown; marginal cell 
evidently acuminate beyond the apex of the second submarginal cell, the first transverso- 
cubital vein curved, and the second cubital cell receiving the recurrent vein nearer the base than 
the middle of its length, beyond which the cubital vein is strongly thickened. The legs are 
exceedingly short. 
O&s.—Most of the characters given above will distinguish this species from L. Halidaii, 
whilst the colour of the head, thorax, and peduncle, the shorter scape to the aniennz, and the 
more Villose and more robust thorax, distinguish it from L. Iligeri, and its considerably larger 
size from L. Swainsonii.

capite (mandibulis antennisque exceptis) castaneo ; peduncalo abdominis transverso-quad- 
rate, supra subconvexo, pedibus brevibus.
