PRISTOilERUS. 511 



apically broadly rouiicled, strongly transverse and, like the 

 strong mandibles, entirely testaceous, the latter with the lower 

 tooth longer. Antennm broken, broadly separated and black, with 

 the scape and the three elongate basal flagellar joints testaceous. 

 T/tora.v shining and distinctly punctate ; notauli entire and deeply 

 impressed ; sternauli basally strong and elongate ; metathorax 

 with complete, tliough not strong, arese ; areola hexagonal, Jialf 

 ^s long again as broad, and emitting the costulaj nearly from its 

 base ; basal area very small ; petiolar area trans-strigose, discrete 

 and basally bisinuate ; spiracles small. Scuiellaiii black and sul)- 

 ■convex. Abdomen black, with the anus indefinitely paler; two 

 basal segments deplanate and finely aciculate, the remainder verv 

 strongly compressed and subglabrous ; the first basally petiolate, 

 with its spiracles but sliglitly beyond the centre ; terebra two- 

 thirds the length of the abdomen and apically sinuate. Leqa 

 slender and testaceous, with the hind femora a little darker ; bind 

 tibiae flavescent, with their apices and a subbasal mark infuscate ; 

 hind femoral tooth minute but distinct, followed by no serration. 

 Wings hyaline and not narrow ; radix and tegulas testaceous, 

 stigma hiteous and large; subrnarginal uervure shorter than its 

 distance from the second recurrent ; basal nervure continuous ; 

 lower wing with the median nervure strong to base, the recurrent 

 longer than the basal abscissa of the radius, and the straight 

 nervellus not geniculate or intercepted ; remaining uervures 

 ■obsolete. 



Length nearly 5 millim.

Tribe PORIZONIDES. 



This tribe is very easily recognised by its triangular radial cell, 

 the very broad stigma, and comparatively small abdomen ; no 

 hesitation can be experienced respecting its members if it be 

 borne in mind that, in addition to the above features, the median 

 nervure of the hind wings is entirely wanting between the 

 nervellus and the base, and that in the front wing the basal 

 nervure is very distinctly thickened at its point of junction with 

 the costa, forming an often not inconspicuous pseudostigma. 

 The two latter points at once distinguish it from the Pjusto- 

 MBRiDES, CREMA.STIDES, and Plectiscides, while from the remainder 

 of the Ophionix.e the large and broadly triangular stigma and 

 not apically pi'oduced metathorax render it very different. 



It has been subdivided into a score of genera, for the most 

 part of doubtful stability, of which only two have hitherto been 

 noticed in our fauna, no doubt owing rather to the lack of 

 observation and collection of such small insects than to the 

 Absence or rarity of si)ecimens.
