good I give a more extended one of the Etna Bay specimen. 

 d". Length 24 m.m. Black, the head and basal two joints of 

 the antennœ red, the outer eye orbits tinged with yellowish ; 

 the 4 anterior tibiaî and tarsi rufo-testaceous, darker coloured 

 behind, tarsi white, slightly tinged with rufous ; wings fuscous 

 hyaline, tinged with violaceous, the nervures and stigma black. 

 Temples, sides and hinder part of the vertex smooth, shining, 

 impunctate, the rest in the centre transversely striated ; the 

 anterior part is much more strongly and widely striated, in 

 the centre, between the eyes, is a longitudinal furrow ; the 

 last keel is behind the anterior ocellus ; from the latter 2 

 keels run below; they converge below and have a less distinct 

 keel between. Front coarsely, transversely rugosely reticulated. 

 Labrum rounded, yellowish. Basal half of mandibles yellow, 

 tinged with red ; the palpi dark fuscous, rufous at the base. 

 The 2'"^ joint of antennae is not quite half the length of the 

 S'"^, the 4"* is slightly, but distinctly, longer than the latter, 

 the 5"' is still longer, being as long as the 2'^'^ and S'''^ united. 

 Apex of pronotum (forming the lesser part) smooth, shining, 

 the rest closely, somewhat strongly transversely striated and 

 with a distinct longitudinal furrow down the middle. Meso- 

 notum deeply punctured, the lateral punctures run into each 

 other ; there is a short longitudinal furrow in the centre of 

 the apex. Scutelluni smooth, sparsely, weakly punctured round 

 the sides and base. Metanotum with round, deep, clearly sepa- 

 rated punctures, the centre smooth, the smooth part twice 

 wider than long ; the apex is transversely striated. Propleurae 

 with a few punctures in the centre, the apex with a few 

 oblique striae. Mesopleurœ aciculated, smooth above, the centre 

 and lower part with small rounded punctures ; the depressed 

 upper part of metapleurse is smooth ; irregularly striated on 

 the apical half; the raised central part bears round, scattered 

 punctures. Abdomen (including the petiole) smooth and shining ; 

 the petiole is not quite so long as the following 2 segments
