128 ENTOMOLOGICAL NEWS. [April, 'l8 



from the distal third of segment 2 (except the other segments broadly 

 proximad) ; large punctures on 7 distinct Propodeum rugose but with 

 five half-complete "median" carinae at base, all well separated. As 

 in the other species. 



One female, Santa Rita Mountains, Arizona, May 21 (H. 

 G. Hubbard). 



Type: Catalogue No. 20681, United States National Mu- 

 seum, the females on a tag, a fore wing and an antenna on a 

 slide. 



Pleurotropis kansensis new species. ' 



$. Similar to quercicola (Ashmead), but segment 2 of the ab- 

 domen is entirely glabrous and occupies but one-fourth of the surface, 

 the scutum is uniformly sculptured and the petiole quadrate. Lateral 

 carinae straight, long, the pair of median very close together. 



One female, Onaga, Kansas ( Crevecoeur). 

 Type : Catalogue No. 20694. United States National Mu- 

 seum, the female on a tag, the head on a slide. 



Polycystus clypeatus new species. 



Characterized by not having the clypeus advanced but its 

 apex tridentate, the teeth subequal ; moreover there is a very 

 narrow, hairlike "tooth," longer than the others, between the 

 third tooth and the sinus at lateral margin. Syntomopus 

 americanus Ashmead has the clypeus tridentate, but the lat- 

 eral teeth are very weak and short, the median one long and 

 conspicuous. Syntomopus affinis Ashmead has the clypeus 

 similarly armed. 



$ . Length, 0.85 mm. Dark metallic green, the wings hyaline, the 

 venation yellow; knees very broadly, tarsi and tips of tibiae white, 

 the tibiae yellow; flagellum beneath suffused with yellow. 



Antennae inserted below the middle of the face but above the ven- 

 tral ends of the eyes, the scrobes inconspicuous; pedicel somewhat 

 longer than wide at apex, longer than any funicle joint; i of funicle 

 quadrate, 6 nearly twice wider than long; ring-joints (2) short, a 

 little unequal. Mandibles 4-dentate. Head and thorax densely scaly- 

 punctate. 



Pronotum transverse. Parapsidal furrows about half complete. 

 Axillae separated. Propodeum neckless, tricarinate, the carinae join- 

 ing around the caudal margin, the cephalic margin to the spiracle 

 foveate, the fovese bounded by carinae, the spiracle elliptical; a 

 spiracular sulcus directly from the spiracle and along the lateral side
