STURMIOPSIS, new genus. 



Genotype. — Sturmiopsis infcrens, new species. 



Differs from Sturmia as follows: Male and female. Parafacials 

 with minute bristles, their profile full or shghtly bulged. Facialia 

 quite strongly ciliate not quite halfway up. Frontaha of female 

 little over half as wide as one parafrontal; those of male narrower 

 than one parafrontal. Eyes rather thicldy hairy in male, tliinly so 

 in female. Antennas inserted almost on eye-middle; frontal profile 

 slightly more produced. Normally only two sternopleurals ; some 

 times two additional very weak ones. Only two lateral scutellars, 

 but the long decussate apical pair with a pair of suberect shorter ones 

 between them. Both sexes with no median macrochaetae on first 

 two segments; no discals on any of the segments; only marginal 

 row on third and anal segments. Hind tibiae ciUate, without longer 

 bristle in either sex. Cubitus much approximated to hind margin of 

 wing, at right to shghtly acute angle; the apical cross vein strongly 

 bent in. Hind cross vein more removed from cubitus.

 parafrontals, thorax, and scutellum rather less thickly so; two linear 

 inner and two heavy outer vittae. Last three abdominal segments 

 broadly but very thinly silvery polUnose. Wings nearly clear. 

 Tegulae wliite, the hind scale somewhat pearly.
