Metopius grandior, n. sp. 



Related to M. montanus, from which it differs in size, color, and sculpture. 



Female. — Length, 15 mm. Head typical ; cheeks minutely, closely sculptured 

 and sparsely punctured ; shield of the face as broad as long, with a faint median 

 longitudinal elevation, closely punctured, the anterior margin almost pointed in 

 the middle; antennae fifty-four jointed, scape and pedicellum together about as 

 long as the first joint of the flagellum plus the second. Thorax very much as in 

 montanus, the dorsulum dull and very closely punctured ; propleura partly stri- 

 ate, partly punctured ; mesopleura with adjoining punctures; metanotum dull, 

 with a median funnel-shaped enclosure, which has the narrow portion nearly as 

 wide as one-half the widest portion ; wings as in montanus, more fuscous along 

 the anterior borders. Abdomen closely punctured, the punctures not distinctly 

 tending to become confluent, the segments not appearing coarsely, longitudinally 

 striate, the elevated portion of the first abdominal segment bounded by a strong 

 carina laterally, the carina not extending much beyond the middle of the seg- 

 ment. Almost uniformly covered with short, golden brown pubescence. Ferru- 

 ginous; shield of face with a narrow prolongation on the front between the 

 antennae and along each eye margin, a spot on malar space, a spot at base of 

 mandibles, a narrow band at base of labrum, coxae and trochanters of four an- 

 terior legs, most of posterior coxte and femora, apical margin of scutellum, post- 

 scutellum, basal abdominal segment, median and lateral spots on apex of third 

 abdominal segment, the fourth, fifth, sixth and seventh segments, except at base, 

 yellow; head, except as mentioned, a median band on the dorsulum, base of scu- 

 tellum, lower half of propleura and mesopleura more or less, metapleura partly 

 along the anterior margin and base of abdominal segments, the third broadly 

 black; antennte brown, blackish above; posterior femora blackish posteriorly, 

 legs, except as mentioned, brownish testaceous.

Bct'thus Eenigmaticus, n. sp. 



In color this species is related to B. howardi. 



Male. — Length, 5.5 mm. Head normal, polished, smooth, tubercles on the 

 clypeus thick and prominent; scape and pedicellum together as long as the first 

 joint of the flagellum. Thorax smooth and polished ; parapsidal grooves not im- 

 pressed; mesopleura with a small, shallow, puncture-like impression in the 

 middle of the sclerite near the posterior margin; metapleura with a short, 

 oblique groove directed forward and downward, and attaining the anterior 

 margin; wings fuscous, stigma and nervures very dark brown; the first abcissa 

 of the radius about one-half the length of the second; transverse cubitus about 

 one third the length of the first abcissa of the radius, the abcissa of the cubitus 

 beyond the transverse cubitus as long or very nearly as long as the transverse 

 cubitus, the terminal abcissa of the cubitus nearly straight; transverse median 

 nervure interstitial, though not exactly, being a trifle beyond interstitial; first 

 recurrent nervure straight, almost as long as the second recurrent nervure which 

 is curved; discocubital nervure not at all broken, with not even a trace of a 

 stump of a vein ; transverse median nervure in the posterior wings broken where 

 the basal fourth joins the succeeding fourth. Abdomen smooth and shining, 

 the thyridia of the second segment close to the lateral margin and parallel there- 

 with, not attaining the middle of the segment, though terminating near the
