PARAMINTHO. 269 
Group SARCOPHAGINE. 
In this group the arista is plumose, but not quite to the end; the macrochete of 
the abdomen are usually present on the last two segments only ; and the male genitalia 
are very prominent and, when not exserted, globular in form. 
These characters are well-defined in the large genus Sarcophaga ; but in some of the 
other genera, which are related more or less to the neighbouring groups, they are less 
evident. | 
Of the five genera of Sarcophagine now known from Mexico, one is not represented 
in the collections before me.

PARAMINTHO, gen. nov.* 
Front broad, flattened, prominent; face perpendicular, not carinated; oral margin slightly elevated; cheeks 
‘broad, convex, somewhat bristly, their inferior portion equalling more than one-half of the longitudinal 
diameter of the eyes; vibrisse at the oral margin and accompanied by several other bristles. Eyes bare. 
Antenne short, inserted above the median line of the eyes; second joint somewhat prominent ; third joint 
a little longer than the second ; arista plumose, except at ‘the end. Proboscis and palpi short ; the palpi 
thin, slightly thickened towards the tip. Abdomen slender, conical; the segments of equal length ; discal 
and marginal macrocheete present on the second and following segments. Legs rather long, with scattered 
bristles; foot-claws and pulvilli (in the ¢) slightly elongate. Wings longer than the abdomen; small 
cross-vein under the end of the first vein; third vein curved upwards in its middle; curvature of the
