the apex of the prouottim, the radical callosities, marks between 

 both base and apex of the- notauli, the mesopleurse below and 

 mesosternal marks, large curved marks on the metapleurse and a tri- 

 lobate one in the petiolar area, citrinous ; mesonotum strongly and 

 closely punctate, more closely between the notauli ; metanotum 

 very strongly punctate; pleura closely punctate, becoming stronger 

 apically, with the propleune centrally striate. Scutellum not very 

 closely punctate, broadly at its sides and apex, and the post- 

 scuteilum entirely citrinous. Abdomen closely punctate, strongly 

 at the base, but more finely towards the anus ; apices of the seg- 

 ments broadly citrinous and dilated laterally ; venter, except 

 basally, and the sides of the second and third segments broadly 

 paler ; terebra less than halt' the length of the body (5 millim.). 

 Legs : anterior pairs flavous, with the tarsi and, to a less extent, 

 their tibiae iufuscate above ; hind femora and tibiae fulvous, with 

 the apices of both black, their tarsi and coxa? flavous, with a large 

 black apical mark on the latter. Wings hyaline, with the stigma 

 and nervures black ; areolet small, longer than broad, centrally 

 sinuate at the emission of the recurrent nervure ; nervelet dis- 

 tinct ; upper basal nervure emitted from the median behind the 

 lower ; first recurrent of the hind wings intercepted shortly above- 

 the centre. 



Length 14 millim.

Head cubical, broadly developed behind the large and parallel 

 eyes ; occiput broadly incised and distinctly, though not sharply, 

 margined ; cheeks elongate ; clypeus not distinctly discrete, 

 apically not produced, but transverse and often obliquely de- 

 riexed ; labrum elongately prominent ; mandibles stout and apically 

 bidentate. Antennae stout and elongate, with the second and 

 third joints of equal length. Thorax with the pronotum centrally 

 tuberculate ; notauli apically distinct ; mesosternum indistinctly 

 sulcate laterally in front ; metathorax large and posteriorly 

 rounded, with but a single basal transverse carina ; spiracles linear 

 arid not elongate. Scutellum large, subdeplanate and apically 

 rounded ; its basal carinse incrassate. Petiole stout and basally 

 constricted, its spiracles nearly central ; penultimate (i. e. 7th) 

 segment strongly developed and nearly as long as the four pre- 

 ceding united ; the apical distinctly longer laterally than the pen- 

 ultimate, with its apex deplanate and obviously discrete ; terebra 

 about half the length of the body. Legs both stout and elongate ; 

 tarsi densely spinose, with the front ones longer than their dis- 

 tinctly basally constricted tibias ; claws simple ; hind coxaa large
