constricted sides of the pronotum, the larger size, the angular nervure 
on the inner margin of the corium, and blackish color. . 
“Moderately large and robust. Head long, hairy, strongly deflected, 
with two distinct, longitudinal furrows (the furrows converging an- 
teriorly) and a distinct median ridge between these furrows, the sides 
very strongly depressed above the eyes, and a longitudinal furrow just 
beneath the eyes and antenne. Eyes prominent, the facets few and 
large. Antenniferous tubercles large, prominent. Antenne very short, © 
a little longer than the head; first, second and third segments subequal, 
the fourth stoutest, longest and fusiform. Buccule large, with a longi- 
tudinal furrow on each side at the base. Pronotum rugulose, very 
coarsely punctate or pitted, beset with a few hairs, moderately con- 
stricted at the sides, with a broad, median longitudinal furrow in which 
are two rather regular rows of fovew, with a rather broad, transverse, 
punctate depression on each side just back of the collar. Collar prom- 
inent, ornated with foveze. Humeri well defined by a sulcus in which is a 
row of six or seven fovexe; posterior margin of pronotum also with a 
transverse row of fovezr. Sides of thorax with quite regular rows of 
fovee. Scutellum distinctly carinate. Rostral sulcus broad; rostrum ex- 
tending a little beyond the thorax. Acetabuli very far apart, especially 
the intermediate and posterior pairs. Legs rather stout, hairy; claws 
very long, almost half the length of the terminal tarsal segment. Entire 
body velutinous. Abdomen densely hairy beneath; connexivum narrow. 
Venter longitudinally depressed in the male, concave in the female. 
Hemelytra with large, hairy nervures. Length, 1.6 mm.; width, .75 mm. 
“Color: General color blackish. Antenne dark-yellow, the terminal | 
segment infuscated. Prothorax blackish, the disc more or less reddish- — 
brown. Legs testaceous, the tips of tarsi infuscated (the claws excepted). — 
Body beneath blackish, the thorax and abdomen covered with a grayish © 
pubescence. Hemelytra white, with dusky patches; nervures brownish- — 
black. Wings white, opaque.”

“Shorter than M. foveata Drake, the pronotum more abruptly con-— 
stricted on the sides, the inner margin of the corium rounded, the head 
and the pronotum reddish-brown or dark reddish-brown, and the dusky - 
patches on the hemelytra evanescent. 
“Macropterous form. Head hairy, strongly deflected, the sides strongly 
depressed above the eyes, with two longitudinal furrows converging an- 
teriorly (a median narrow ridge between the longitudinal furrows), a 
longitudinal furrow on each side of the head just beneath the eyes and 
antenne. Antenniferous tubercles large and prominent. Antenne short, 
a little longer than the head; first, second, and third segments subequal; 
fourth segment longest, stoutest, fusiform. Rostrum reaching a little 
beyond the posterior coxze. Pronotum rugulose, coarsely punctate, 
sparsely hairy, the sides more abruptly constricted than in foveata, with 
a transverse, punctate depression on each side just back of the collar. 
Collar prominent, ornated with fovere. Scutellum with a narrow median 
carina. Sides of thorax with somewhat regular, transverse rows of 
fovez. Abdomen hairy beneath; venter is slightly depressed longitudi- 
nally and convex in the female. Hemelytra with large, prominent ner- 
vures; the inner nervure of corium broadly rounded. Wings about as 
long as the hemelytra. Length ( a and ? ), 1.45 to 1.5 mm.; width, 
about .65 mm.
