striae above the insertion of the antennae; pedicel twice as long as 



wide, as long as joints three and four united, as wide as four; three 



a little longer than wide, narrower than four; five equal to four; six 



wider, slightly longer than wide; seven to nine mder than six, as wide 



as long; ten as long as the pedicel, sharply pointed apically, the upper 



side slightly curved ; thorax three-fourths as wide as long, broadened 



and rounded anteriorly, convex above, as high as wide; pronotum 



aciculate; mesonotum shining, faintly shagreened on anterior half; 



notauli distinct on basal half, the median lobe rounded posteriorly; 



scutellum transverse, highly convex, polished, sparsely pubescent; 



abdomen elliptical, a little over twice as long as wide, narrower than 



the thorax, as long as the head and thorax united, 



pointed apically; first tergite strongl}^ fluted, 



nearly perpendicular on the sides; dorsolateral 



ridges near the edge of the segment, the median 



area transverse, subconvex; second tergite a little 



longer than wide, not much narrowed anteriorly, 



the sides but slightly curved; tergites three to six 



unsculptured, equally long, united somewhat over 



soLiDAGiNis (AsHMEAD). half as loug as the second; six a little wider than 



Head of female, long;, subacutc; legs piccous ; trochanters, all tibiae

basally, anterior tibiae apically, and all tarsi (ex- 

 cept the last joint of each) ; yellowish. 



The relative length of the abdomen is variable, due to the tele- 

 scoping of the terminal segments. Sometimes it is as long as the 

 head and thorax united and at other times scarcely longer than 

 the thorax. 



Male. — Length 1.30 mm. Projection of vertex somewhat less prom- 

 inent than in the female; pedicle one-half longer than wide; third joint 

 triangular, transverse, as wide as the pedicel, narrower than the fourth; 

 four as long as the pedicel, widened and with a short projection below 

 at apical third, rounded apically, not much longer than wide; joints 

 five and six oval, one and one-half times as long as wide, narrower 

 than four; seven to nine as long and indistinctly wider than five and 

 six; ten as long as three and four united, pointed apically, the sides 

 parallel nearly to the apex; abdomen a little longer and narrower 

 than the thorax, not quite twice as long as wide; wings hyaline, ex- 

 tending one-third the length of the abdomen past its apex. 



The coloration of the legs is variable. They may be mostly yellow 

 (partly brown) , or mostly black (partly yellow) . One male has the 

 abdomen as wide as the thorax, another as wide as the thorax and 

 distended, as long as the head and thorax united.
