 1898, p. 116, pi. A. tigs. 5, 5 « ( $ ). 



Head cubical, glabrous and nitidulous, dark blue or metallic 

 green, Mitli the internal orbits botli above and more broadly below 

 the antennte, and the cheeks broadly, white. Antenna' filiform and 

 black, with the tenth to sixteenth, and sometimes the four apical, 

 flagellar joints white. Thorax rugose, metallic green and imma- 

 culate; mesonotnm oval and elongate, with the notauli deeply ini- 

 ]n*essed and extending to its base ; metathorax apicuUy rounded, 

 shagreened, with four irregularly sinuate longitudinal carinas, of 

 which the inner pair extend to the apex and there terminate in a 

 distinct red tooth on eitiier side of the petiole ; costulfe emitted 

 beyond centre ; basal area parallel-sided and apically open ; 

 spiracles linear. Scntelhun immaculate. Abdomen dark shining 

 blue or green, with the base and a diamond-shaped or transverse 

 fascia on the first, a similar fascia on the second, and the extreme 

 apical discal margins of the three or live following segments, clear 

 flavous ; eighth segment elongately exserted and brunneous ; the 

 basal segments subdeplanate, the apical subcompressed, and the 

 second and third triangularly impressed discally ; spicula black, 

 with the valvulae white- banded before their apices, hardly a third 

 shorter than the body (13 millim.). Leys flavous, with the anterior 

 pairs sometimes dark-marked; the hind j.iair with the apices of 

 the cox?e subinfuscate, of the femora and tibiae, with the claws

 sinuate and constricted. Whufs hyaline, sometimes with an

Ti/pe. Location unknown. 



Bingham's description of the coloration of the anterior legs is 

 a little involved, but apparently all the joints in the typical form 

 are more or less nigrescent at their apices ; I have, however, seen 

 the anterior legs immaculate testaceous.

Epirhijssa annulicornis, Cameron, Mauch, Mem. 1899, p. 133 ( $ ). 



A coerulescent species with fulvous markings, the apical half of

 nitidulous and csjeruleous, with the cheeks, frontal orbits and outer 

 orbits below broadly, and the clypeus laterally (more narrowly
