of a vein on the discocubital nervure. Abdomen mostly dull; petiole with lateral 

 ridges that just attain the spiracles, basal third of the petiole largely polished 

 and without sculpture of any kind, the middle and apical thirds of the segment 

 minutely roughened and rather indistinctly, longitudinally striate; the second 

 segment very closely punctured with small, shallow, rather indistinct punctures 

 that give a dullish appearance; the following segments smooth, more shinicg 

 and apparently impunatate and devoid of appreciable sculpture. Covered with 

 short, inconspicuous, whitish pubescence. Black; joints 10 to 17, inclusive, of 

 the antennae yellow, the ninth joint partly yellow; orbits, from a little back of 

 the middle of the top of the eye to a little below the insertion of the antencje 

 within, with a narrow yellow band; superior margin of the prothorax interrupted 

 in the middle, a transverse band below the tegulte, basal two-thirds of the ante- 

 rior tibife externally, basal half of the middle tibite and a little more than the 

 basal third of the posterior tibite white; anterior tibise beneath, the apical third 

 entirely and the tarsi of anterior legs brown.

This might be referred to I. ferrugator Kirby, but that is said to have distinct 

 lateral spines or teeth on the metathorax. 



Male. — Length, 14 mm. Head shining; face closely, distinctly punctured, 

 the punctures near the antennte rather confluent and apparently between stride ; 

 punctures of the cheeks and clypeus more separated than the punctures on the 

 face ; malar space about as high as the mandibles are broad at base ; scape and 

 pedicellum together as long as the first joint of the flagellum, antencse forty-three 

 jointed. Thorax mostly shining; dorsulum and mesopleura shining, with sep- 

 arated punctures, many of the punctures separated like the punctures of the 

 clypeus; scutellum more sparsely punctured than the middle of the dorsulum: 

 metathorax dull rugulose, the metapleura excepted where the surface is shining 

 and the punctures close together, adjoining or nearly, basal area of the superior 

 face of the metathorax nearly obliterated, areola distinctly broader than long, 

 rather horse-hoof shaped, but nearly as wide at apex as at base, the petiolarea 

 indistinctly or not at all defined, so it appears to occupy all of the posterior face 

 of the metathorax, the lateral areas not well separated from each other; wings 

 strongly brown, stigma and nervures dark brown; the pentangular areolet with 

 the transverse cubiti and first cubital side of equal length, the radial side two- 

 thirds or a little more the length of the first transverse cubitus and equal or very 

 nearly to the length of the second cubital side. Abdomen dull; petiole rather 

 shining, not coarsely but somewhat longitudinally sculptured, the broad apical 

 portion very uneven, produced into distinct elevations; the succeedicg segments 

 with rather distinct adjoining punctures, the apical segments shining with the 

 punctures rather separated and more indistinct than elsewhere. The pubescence 

 is whitish and thin, nowhere very conspicuous, most abundant and apparent on 

 the dorsulum and metathorax. Black ; legs, except coxa? and trochanters which 

 are black, abdomen, except petiole which is black, almost entirely yellowish fer- 

 . ruginous to ferruginous; base and sides of second abdominal segment and base 

 of third with blackish, the posterior femora dark brown at apex.
