more closely and the postscutelluni still more closely and finely punctu- 

 red. In the centre of the base of the metanotum are two areae, longer 

 than wide, divided by a stout keel, the outer edges at the apex rounded 

 and with two irregular oblique keels near the base; next to this is a 

 larger area, which, at the outer basal part, is continuous with a longer, 

 narrower, bounding area, with two stout keels at the spiracles, above the 

 apical slope is a row of deep areae, longer than broad. Propleurae punc- 

 tured, but not strongly or closely, the apex smooth. Metapleurae smooth 

 at the base, the rest stoutly obliquely striated. Abdomen closely punc- 

 tured, the segments fringed with pale golden hair. Pygidium strongly 

 punctured, smooth down the centre; epipygium brownish, raised above 

 over the pygidium. The oblique depression on the second ventral segment 

 is bordered above by two curved furrows w^hieh unite in the centre. The 

 apical abscissa of the radius is acutely angled below the middle; the 

 second abscissa of the cubitus distinctly shorter than the basal; both 

 the recurrent nervures are received shortly beyond the middle; nervures 

 and stigma black.

Black, the underside and apex of flagellum of antennae rufo-tes- 

 taceous; mandibles broadly rufous at the apex; palpi testaceous; fore 

 tarsi and tibiae in front rufous; metanotum with two keels; wings 

 hyaline, the nervures black. Male. Length ti.5 mm. 8an Marcos, Nicara- 

 gua. 



Head closely punctured, densely covered with silvery hair, the 

 cheeks, face, and clypeus much more densely with long white hair and 

 white pubescence. Pronotum sharply keeled at the base, the apex smooth, 

 the middle closely punctured. Mesonotum with large scattered punctures, 

 the sides bordered by a curved foveate furrow. Scutellum punctured, 

 except in the middle at the base. The centre of the metanotum between 

 the keels smooth, bare, shining, the top and apex of the meta-pleurae 

 strongly, irregularly striated, the striae clearly separated. First segment 

 of abdomen smooth, except for a band of large irregular punctures on 

 the base of the dilated apex; the apex near the end has a transverse, 

 deep, crenulated furrow; there is a broader, more curved, similar furrow 

 on the base of the second. The apical half of the abdomen, as usual, is 

 more thickly haired and more closely and strongly punctured. Comes 

 near to T. carinata Cam. and T. rugosa Cam. but is much smaller and 

 has only two keels on the metanotum. It is the smallest species known 

 fron Central America.
