LISSONOTA. 225 



present genus are entirely homogeneous and at once known from 

 those of allied genera by their elongate and narrow abdomen, 

 simple tarsal claws, circular metathoracic spiracles, evenly sculptured 

 and excarinate metanotum, elongate terebra and the comparatively 

 constant shape of the normally entire areolet. Unlike the False- 

 arctic representatives, all our Indian species are brightly marked 

 and banded with flavous, and so much attention is paid to these 

 decorations in descriptions that few structural details upon which 

 to found a table of the species have been cited. The following 

 may, perhaps, serve, though it should be worked with the table of 

 Syzeuctus, as intimated above.

155. Lissonota brevicauda, sp. n. 



$ . A small black species, with the body marked and the 

 antennae banded with white, legs mainly fulvous and wings 

 hyaline. Head subvertical behind the eyes, dull, closely and 

 evenly punctate; black, with the facial orbits very broadly to 

 apices of elongate cheeks, the indistinctly discrete glabrous and 

 convex clypeus, and the mandibles (except their bidentate apices), 

 stramineous ; face deplanate and more sparsely punctate laterally, 

 irons flat, with the scrobes small and entirely punctate. Antenna? 

 fully as long as body, very slender and strongly attenuate apically,
