Genus HOUGHIA, new genus. 
The characters of this genus may be gleaned from the table of genera 
given on previous pages, and the following description of the type spe- 
cies: Black, the palpi and apex of proboscis yellow; front of female 
five-sixths as wide as either eye, frontal bristles descending almost to 
middle of second antennal joint, two pairs of orbital bristles and two 
pairs of backwardly curving macrochaetae outside of the frontal bris 
ties, cheeks one-twelfth as broad as the eye-height, four or five bristles 
above each vibrissa 1 , antenna' almost as long as the face, the third 
joint from four to five times as long as the second, arista thickened on 
the basal two-fifths, the penultimate joint broader than long; thorax 
gray pollinose, marked with four black vitta 1 , four postsutural and 
three sternopleural macrochaetae, scutellum bearing three long mar- 
ginal pairs and a very short apical pair; abdomen shining, the last 
three segments except their apices whitish pollinose, each segment 
bearing marginal macrochaetae \ middle tibia' each bearing a single 
macrocha'ta on the front side near the middle, hind tibia' outwardly 
subciliate; wings hyaline, first vein bristly except on its base and 
apex, third vein bristly almost to the small crossvein, hind crossvein at 
last third of distance from the small to the bend of the fourth, the lat- 
ter not appendiculate, calypteres whitish: length, 6 to 7 mm. Tiftou, 
Ga. Two females collected June and September 1, 1890, by Mr. G. R. 
Pilate, and transmitted by Dr. Garry deX. Hough, after whom the genus 
is named. Type No. 3623, U. S. National Museum setipennis n. sp.

Tachinomyia Townsend, Trans. Anier. Ent. Soc, Vol. XIX, p. 96; April, 1892. 
Eutachina was proposed for Tachina under the mistaken idea that 
the latter is identical with the genus Eehinomyia. Clnetotaehina is 
given by its authors as a subgenus of Eutachina. 1 The synonymy of 
Tachinomyia is by the Avriter and is based on a cotype specimen of the 
type species. Our species have three sternopleural ruacrochaBiae, and 
two or more on the front side of each middle tibia near the middle: 
1. Apices of last three segments of abdomen shining black, tip of abdo- 
men black, genitalia not or only slightly projecting beyond the 
tip of the fourth segment, frontal bristles descending on sides 
of face nearly halfway to the vibrissa*, facial ridges bristly 
almost to the lowest frontal bristles 2. 
Apices of last three segments of abdomen usually opaque gray 
pollinose, apex of scutellum and of abdomen usually yellow, 
genitalia of male projecting more than half the length of the 
Zweif. Kais. Mus. Wien, VI, p. 125; 1893.
