Ferrugineus ; apice antennarum nigro, medio sordide flavo ; alis nigris. $ . 

 Long. 12 millim. ; terebra fere 4 millim. 



Hab. Mexico, Valladolid in Yucatan (Gaumer). 



Antennae as long as the thorax and abdomen together ; stout, thickened towards the 

 apex, the third and fourth joints equal. Head a little broader than the mesothorax, 

 punctured and semiopaque, except above the antennae; front projecting in the middle, 

 a furrow on either side of it ; clypeus projecting, a semitransverse furrow at its base ; a 

 distinct furrow runs down from the ocelli to the antennae, through the. centre of the 

 depression. Mesonotum minutely punctured, the furrows distinct in front ; the pleurae 

 longitudinally striated (the striations large and curved). Scutellum shining, faintly 

 punctured. Metathorax strongly transversely punctured ; the base (behind the upper 

 transverse keel) aciculate and sparsely punctured ; the second transverse keel interrupted 

 in the middle; without tubercles. Petiole smooth, impunctate, and shining; the 

 postpetiole raised a little in the centre, a longish depression at the sides. The remain- 

 ing abdominal segments semiopaque, and finely and closely punctured ; sheaths of the 

 ovipositor black. Legs longish, stout. Areolet longer than broad, the lower side some-

This species comes very near the preceding, but is probably distinct. The metathorax
