side of the middle, and a small, double, fulvous spot behind 

 the middle: scutel with a white lateral spot': metathorax 

 with a white line at base and an oblique one each side 

 towards the tip: tergum \dv\ed with yellow and black

or green and black ; the posterior margins of the segments, 

 dull rufous ; about four distinct black spots : feet honey- 

 yellow ; thighs black beneath : tarsi paler: venter honey- 

 yellow, with a black spot before the anterior spine. 



Length from seven tenths to four fifths of an inch. 



With the short maxillary palpi and the one toothed 

 mandible of Bembex, this insect has the radial and last 

 cubital cellules as widely separated at their tips as in 

 MoNEDULA. The proboscis is not folded, but extended 

 horizontally beneath the body. These characters may 

 justify the formation of a distinct genus, or at least of a 

 division, under the name of Steniolia. 



2, B. fascidiay Fabr. A male in my cabinet has 

 six bands upon the tergum and two spots on the ultimate 

 segment ; the first band is double the width of that of the 

 female, and is interrupted by a very small space only ; 

 second band not interrupted, but its two lunules are so 

 continued as to enclose two black spots j third band with 

 the lunules not or hardly interrupted ; fourth and fifth 

 bands interrupted ; sixth band entire, undulated ; spots on 

 the ultimate segment, orbicular; the female has but five 

 bands.
