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



Head cubical, glabrous and nitidulous, dark blue or metallic 

 green, with the internal orbits both above and more broadly belo\v 

 the antennae, 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; mesonotum oval and elongate, with the notauli deeply im- 

 pressed and extending to its base ; metathorax apically rounded, 

 shagreened, with four irregularly sinuate longitudinal carina?, of 

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

 distinct red tooth on either side of the petiole ; costulae emitted 

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

 spiracles linear. Scutellum 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, arid the extreme 

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

 Havens ; 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 pair with the apices of 

 the coxae subinfuscate, of the femora and tibiae, with the claws 

 and onychii, black ; hind tarsi stramineous ; anterior tibiae basally 

 sinuate and constricted. Wiyg hyaline, sometimes with an 

 infumate cloud at the junction of the radial with the cubital cells ; 

 tegulae and nervures testaceous. 



Length 17 rnillim.

Type. Location unknown. 



Bingharn'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. 



42. Xylonomus annulicornis, Cam. 



Epirhyssa annulicornis, Cameron, Manch. Mem. 1899, p. 133 ( $ ). 



A caerulescent species with fulvous markings, the apical half of 

 the flagellum white and the terebra shorter than the body. Head 

 nitidulous and caeruleous, with the cheeks, frontal orbits and outer- 

 orbits below broadly, and the clypeus laterally (more narrow ly 

 below), flavous ; face somewhat strongly punctate ; clypeus sub- 

 itnpunctate, densely and elongately fulvous-pilose, centrally and
