Genotype, Porizon liostllls, Grav. 



Head with the maxillary palpi quadri-articulate and the orbits 

 not pale. Antennse often apically attenuate, with the ilagelluui 

 multi-articulate. Thorax generally cylindrical and much longer 

 than high ; sternauli always distinct ; metathorax with no costulse or 

 lateral carinte ; basal area rarel}' entire ; petiolar area not extending 

 beyond centre. Abdomen short, with the petiole stout and some- 

 times discally excarinate ; second segment not transverse, with large 

 and triangular thyridii ; terebra reflexed and usually stout. Hind 

 femora simple and somewhat slender ; calcaria curved ; hind tarsi 

 elongate, with the joints gradually decreasing in length to apex. 

 Stigma broad and generally emitting the radius beyond its centre ; 

 areolet not entire, obsolete or wanting, Avith the submarginal 

 nervure very short ; anal nervure not arcuate, emitted from below 

 centre of brachial cell ; basal nervure subtriangularly thickened 

 at the costa ; radial cell with its lower angle subacute ; nervellus 

 not geniculate ; basal abscissa of radial nervure in lower wing- 

 equal in length to the recurrent nervure. 



liange. Most of the species of this genus are Paloearctic or 

 Kearctic, though a few have been found in Cuba, &c., and their 

 rarity in the tropics is probably due simply to ^ant of observation. 

 Only three Indian specimens have passed through my hands.
