fere totis, coxisquo flavis ; pedibus pallide ferrugineis flavo- 

 variegatis ; alis hyalinis, flavo tinctls, venis fuscis. 

 $. Nigra; scutello tibiisque extus flavo-testaceis ; segraentis 

 dorsalibus primo tertioque fascia lata transversa, quarto, quinto 

 sextoque macula obscura lateral! utrinque flavo-ochraceis ; seg- 

 mento dorsali secundo carinis 9 transversis. 

 Long., J 17, $ 10 mm. 



c? . Clypeus convex, sparsely punctured, broadly truncate 

 at the apex, the ang^les not produced, ahuost pointed at the 

 base, luterantennal prominence well developed, connected 

 with the base of the clypeus by a short narrow carina, 

 divided by a longitudinal sulcus which almost reaches the 

 anterior ocellus. Eyes slightly divergent towards the 

 clypeus, the posterior ocelli as far from each other as from 

 the eyes, the anterior ocellus situated in a depression. 

 Antennse about as long as the thorax and median segment 

 combined, the joints not arcuate beneath, the apical joints 

 not quite so stout as the basal. Head closely but not 

 coarsely punctured, thorax and abdomen more sparsely 

 punctured, subopaque ; mesopleurae very closely atid finely 

 punctured. Scutellum ending in a blunt point ; post- 

 scutellum depressed below the scutellum, the apex subacute 

 and produced beyond the base of the vertical truncation of 

 the median segment. First abdominal segment as broad as 

 the second, vertically truncate anteriorly ; sixth ventral 

 segment with an acute spine on each side at the apical 

 angles. Seventh dorsal segment produced into a fiat 

 process, longitudinally striated. Hypopygium obliquely 

 striated above, as broad at the base as long, with a strong 

 spine on each side near the base, narrowed towards the apex 

 and rather broadly truncate at the base of the stout apical 

 spine. Third abscissa of the radius longer than the second, 

 first recurrent nervure received at three-quarters from the 

 base of the second cubital cell, second just beyond one- 

 quarter from the base of the third cubital cell. 



? . Head rather small, no broader than the pronotum ; 

 mandibles falcate, acute at the apex ; clypeus without a 

 carina, punctured. Front with a deep excavation on each 

 side, smooth and shining ; the excavations elongate and 

 nearly reaching the eyes, separated by a rather narrow 

 elevated space the lateral margins of which are raised into 

 carinae, the space between the carinse punctured, with an 

 obscure median carina and a few long cinereous hairs. 

 Vertex smooth and shining, the posterior margin of the head 

 widely emarginate. rronotum coarsely and shallowly punc- 

 tured, with a low median carina from the base to the apex.
