tal bristles mostly black above and yellowish at the sides, beard 

 white. Thorax furnished with yellow dust, mid-dorsal stripe dark, 

 narrowly divided anteriorly. Legs to the tips of the femora pure black, 

 tibia yellow with black tips, metatarsi mostly yellow, other tarsal 

 segments black, each with a narrow yellow base. Abdomen brown 

 with narrow, light colored posterior margin to each segment. Male 

 forceps about as long as abdominal segments six, seven and eight, ovi- 

 duct shining black, first segment equal in length to abdominal seg- 

 ments six and seven, apical segment slender and style like. 



The species is distributed, at least, from North Carolina to Canada 

 and most specimens have been taken near the Atlantic coast, although 

 there are records for Ohio. 



Asilus antimachus Walker. 



A light brown species with clear white m^^stax and with the legs 

 almost wholly reddish. Length 16-20 millimeters. 



Face and front clothed with gray dust. Facial gibbosity rather 

 prominent, mystax and beard white; in some specimens there may be 

 a very few black hairs just above the oral opening and once in a great 

 while a specimen may be found that has a few short black hairs in the 

 extreme upper part of the mystax; palpi and proboscis black, the 

 former with black hair; some of the occipito-orbital bristles may be 

 black but most of the hairs over the whole occiput are white ; antennae 

 black ; first two segments together plainly longer than the third which 

 is somewhat shorter than its arista. Thorax clothed with gray dust 

 on the sides, and with 3^ellowish dust above, mid-dorsal stripe and some 

 spots on either side dark brown. Wings hyaline with slight coloring 

 at apex and along the posterior border. Coxae colored like the sides 

 of the thorax, femora largely red in most specimens, but varying from 

 one having a small elongate black spot on the anterior side to one large- 

 ly black with a wide preapical band ; tibiae yellow, each with the apex 

 narrowly black or brown, metatarsi yellow, each with a black tip; 

 other tarsal segments black, some at least with yellow bases. Abdo- 

 men dull grayish brown, posterior margin of each segment lighter but 

 the contrast between the segment and its margin not so pronounced 

 as in novae-scotiae. 



Common in various sections of Ohio in late summer. Specimens 

 also from Indiana, Kansas, Virginia and Missouri. In the locality of 

 Akron, Ohio, the species is abundant on weeds and in the pastures 

 during the greater part of August. 



Asilus maneei n. sp. 



A small black species with black legs, gray stripes and markings on 

 the thorax and gray posterior borders to the abdominal segments. 

 Length 10-12 millimeters. 



Facial gibbo.sity rather prominent, mystax composed of a mixture 

 of gray and black hairs, face and front black btit sparsely clothed with 

 gray dust, beard white, occipito-orbital bristles black, proboscis and 

 palpi black, the latter with black hair. Thorax black, largely cov- 

 ered with gray dust, the mid-dorsal stripe black but distinctly divided
