Vipio piceipectus, n. sp. 



Related to croceus, from which it is at once separated by the shorter ovi- 

 positor. 



Female. — Length, 7 mm. Head shining and polished, face dullish, minutely 

 sculptured, vertex sparsely punctured, the space between the antennie and ocelli 

 not deeply impressed, but with a narrow median groove; pedicellum a little more 

 than half as long as the first joint of the flagellum; first joint of the flagellum 

 nearly as long as the next two joints combined. Antenn;e more than thirty eight 

 jointed; broken. Thorax polished, the parapsidal grooves rather deeply im- 

 pressed; metathorax rather indistinctly punctured, the sinuate impressed line 

 on the metapleura quite deep, the adjoining surface rather closely punctured ; 

 wings strongly brownish, nervures and stigma nearly black. Abdomen shining 

 and polished; first segment with a median elevated convex disc that is longi- 

 tudinally striate, smooth on the anterior and posterior edge, an uneven space on 

 each side of the central disc, the space bounded by a narrow fold that constitutes 

 the upper lateral edge of the segment, the lower lateral edge not extending be- 

 yond the upper lateral edge, a very narrow groove lies between these edges; sec- 

 ond segment with three smooth triangular spaces at the base of the middle space 

 largest and terminating posteriorly in a narrow polished raised line, the remain- 

 iDg portion of the segment with closely arranged longitudinal stria? that do not 

 attain the posterior border of the segment which is smooth; third segment with 

 lateral basal, triangular, smooth spaces and small median triangular space which 

 is rather striated and has the apex prolonged as a low ridge, in the middle of the 

 segment the basal half is striated longitudinally, on the sides the strite extend 

 further back, but leave a broad smooth margin at the apex of the segment, 

 the bifurcation of the crenulate furrow is not sharply defined; the fourth seg- 

 ment is smooth in the middle and has short stria? prolonged from the base at the 

 sides of the segment; fifth and sixth segments smooth; ovipositor a little longer 

 than the abdomen. Honey yellow; antenna> black at base, the flagellum largely 

 dark brown; anterior legs black, excepting the apex of the femora, tibit^, and 

 tarsi; tips of the mandibles, pectus, middle legs excepting joints black; trochan-
