Spanoparea-Morpholeria-Acantholeria group, from which Neoleria 
differs in having the anterior and posterior fronto-orbital bristles 
about equal in length. Other characters of the genus are: third 
antennal segment large and round, the arista relatively short and 
minutely pubescent; dorsocentral bristles 1-+3, but anterior bristles 
in some species weakened so that they are hardly distinguishable; 
scutellum bare except for the usual 2 pairs of lateral bristles; pro- 
pleural bristle present, 2 in N. fuscolinea (Garrett); mesopleuron bare 
except for several setae sometimes present in anterior corner; sterno- 
pleuron with 1 or 2 bristles in upper hind corner, several hairs or setae 
in front of the bristle and longer hairs ventrally between the coxae; 
remainder of pleura bare; prosternal bristles absent; middle tibia 
with several ventral apical bristles.

4. Mesonotum uniformly vellony i yellow orange. .. . . . . lutea (Loew) 
Mesonotum mostly grayish brown or black, with the none and (or) a portion 
of the scutellum yellow... . . . . inseripta (Meigen)

Neoleria inscripta (Meigen) 
Helomyza inscripta Meigen, 1830, p. 59. 
Helomyza humeralis Zetterstedt, 1838, p. 767; 1847, p. 2455. 
Blepharoptera inscripta (Meigen), Loew, 1859, p. 66. 
Blepharoptera leucostoma Loew, 1863, p. 28 (Centuria 3, 53). 
Blepharoptera humeralis (Zetterstedt), Meade, 1899, p. 101. 
Leria repetenda Pandellé, 1901, p. 347. 
Leria leucostoma (Loew), Aldrich and Darlington, 1908, p. 87. 
Neoleria inscripta (Meigen), Czerny, 1924, p. 123; 1927a, p. 29. 
Neoleria leucostoma (Loew), Czerny, 1924, p. 124. New synonymy. 
Specimens of this species in North American collections have often 
been labelled discolor Loew, which is in Spanoparea, and leucostoma 
Loew, which is a junior synonym of Neoleria inscripta (Meigen). 
2T am not able to place Neoleria czernyi (Garrett) in this key.
