fine vertically impressed line above it ; antennal carinoD rather wide 

 apart, short but prominent; antennne of moderate length, the scape 

 very nearly extending to the top of the head ; eyes lateral, rather 

 small, placed about tlie middle of the iiead. Thorax with the 

 characters of the genus, a slight transverse carina between the 

 prouotal spines, the latter triangular, dentate : mesonotum with a 

 prominent transverse carina about the middle, generally bidenbate; 

 basal portion of metanotura short, widening posteriorly, the meta- 

 notal spines long, acute and slightly curved. Pedicel rather long, 

 the nodes punctured and opaque, transverse ; the 2nd node 

 liroader than the 1st, this latter with a moderately long petiole in 

 front and a shorter one posteriorly, the upper margin straight with 

 distinct lateral angles ; the 2ud node rounded above ; alxlomen 

 broadly oval.

^ . Greatly resembles L. fn(adrispi)iosiis, Jerd., but constantly 

 differs as follows: — Smaller, the head proportionately narrower; the 

 pronotal and metanotal spines, especially the former, more robust 

 and longer ; the metanotum has in the middle two obtuse low 

 tubercles, instead of the very distinct bidentate carina as in 

 L. tjuadrispinosus ; the nodes of the pedicel are smooth and 

 shining, not punctured and o])aque. In the typical specimens from 

 Karennee the colour is a pale dull yellow, but specimens I have 

 from both Upper and Lower Burma are more or less shining 

 chestnut-brown, with the thoracic spines and the form of the 

 mesonotum characteristic of L. hurmanus.

^ . Adult light yellowish with a tinge of brown to a fairly dark 

 yellowish brown, the legs paler. In some specimens the abdomen 

 and legs are much paler than the head and thoi'ax ; for the most 

 part smooth and shining with a fe\\' iudistinct punctures, the 

 metanotum finely and closely punctured and rugulose ; pilosity 

 pale and very sparse. Head longer than broad, slightly convex, 

 much broader jjosteriorly than in front, the sides convex, the 

 posterior margin distinct; mandibles broad, finely rugulose ; clypeus 

 convex, its anterior margin slightly bent inwards ; autennal carinae 

 short, wide apart ; antennae long and somewhat massive, the scape 

 extending to the top of the head ; eyes comparatively large.
