SPATHIMEIGENIA MEXICANA, new species 



Besides having all the characters mentioned as pertaining to the 

 genotj'pe, the following may be mentioned : 



Male. — Front rather narrow, at narrowest about 0.21 of head 

 width (three measured : 0.2, 0.22, 0.22) ; pollen deep golden on 

 parafrontals, parafacials, and posterior orbits; face with yellow 

 pollen; facial ridges bristly about halfway up; antennae black; 

 palpi yellow. Thorax with gray pollen, on which are two pairs of 

 inconspicuous stripes, ending considerably before the suture. Abdo- 

 men elongate; irregular discals of several sizes on last three seg-

 last three segments, the apical third or thereabouts brown ; generally 

 in an oblique side view it will appear light on one side of the middle 

 line, dark on the other, and these shades will reverse themselves in 

 a dilferent view. Tip of fourth joint red, sometimes a little red on 

 sides of second, rarely on third. Legs black. Anterior tibia with 

 a single outer posterior bristle ; middle tibia with one on outer front 

 side, one flexor, and two on outer hind side. Hind tibia with a 

 scattering row of bristles of unequal size on outer hind side. Wings 

 distinctly infuscated toward base, third vein with two or three 

 hairs. 



FeTTiale. — Front narrowest at extreme vertex, where it measures 

 about 0.29 of head width (three measured : 0.27, 0.3, 0.3), thence very
