divorus Cushman differs as follows : Head in dorsal view more than 

 twice as wide as long; temples less strongly rounded and more sloping; 

 eyes distinctly longer than width of face, parallel, only about two- 

 thirds as wide as long; clypeus broadly but strongly rounded at apex, 

 but little more than half as long as interfoveal line; malar space 

 barely half as long as basal width of mandible; cheeks not rounded 

 below eyes; ocell-ocular line barely half as long as postocellar line, 

 diameter of ocelli distinctly greater than former; propodeum less 

 strongly arched and extending only about one-third of way over 

 coxae; mesopleural impression distinctly, transversely striate; 

 sternauli rather strong; mctapleura less densely punctate than 

 mesopleura; areola and petiolar area subequal in length, the areola 

 slightly narrower, petiolar area nearly as wide as long, rather strongly, 

 transversely striate; vestiture of head and thorax inconspicuous; 

 stigma slightly narrower; nervulus briefly postf ureal; hind basitarsus 

 relatively shorter. Abdomen nearly twice as long as head and thorax; 

 postpetiole slightly elevated above level of petiole; ovipositor only 

 about one and one-half times as long as first tergite. 



Black; yellow color of head embracing also the face; pronotum, 

 sternauli and lateral edges of mesoscutum 3"ellow; mesopleura and 

 metapleura piceous with an obscure yellowish spot at base of each 

 coxa; scutellum yellowish red; tergites 1 and 2 black, becoming 

 piceous toward apex; other tergites broadly yellowish laterally; 

 legs colored as in cleridivorus, but hind legs, especially coxae, paler. 



Type-locality. — Probably Michigan. 



Type.— Cat. No. 20269, U.S.N.M. 



One female from A. J. Cook, Lansing, Michigan, July 30, 1887. 



CREMASTUS (ZALEPTOPYGUS) ROSAE, new species. 



Female. — Length 6 mm., antennae 4 mm., ovipositor 2.3 mm. Very 

 closely allied to plesius Cushman and differing from that species as 

 follows: Eyes barely as long as width of face, about three-fourths as 

 wide as long; clypeus two-thirds as long as interfoveal line; malar 

 space about three-fourths as long as basal width of mandible; cheeks 

 slightly rounded below eyes; ocell-ocular line nearly as long as post- 

 ocellar line, diameter of ocelli nearly as long as former. Propodeum 

 extending about two-fifths of way over hind coxae, areola much 

 narrower than petiolar area, the latter distinctly longer than wide. 

 Abdomen but little more than one and one-half times as long as head 

 and thorax; first and second tergites subequal in length and together 

 but little longer than rest of abdomen; postpetiole only about as long 

 as petiole and rather abruptly swollen. 



Color similar to pleisus except that entire mesopleura, metapleura, 

 and propodeum, except basal areas, are red.
