K0.2219. ^1 REVISION OF TlIK VliEMA^TlNI—CVtillHAS. 641 



Eight years later the same writer synonymizod the two species and 

 called it Cremastus fusiformis. Since incompletus has page prece- 

 dence over fusifo7^7nis, the earlier name must be used. The fact that 

 Provancher described another species under the name Atradodes in- 

 completus docs not alter the case, since the present species was never 

 referred to Atradodes nor has the name incowpletus ever been used in 

 Cremastus. 



From most of the species which fall near it, this species is readily 

 separable by its small size and entirely black thorax and abdomen, 

 and from the few species which approach it in these characters by the 

 very characteristic arrangement of color in the orbits. 



CREMASTUS (ZALEPTOPYGUS) ROHWERI, new species. 



Female. — Length 8.5 mm., antennae 5 mm., ovipositor 3.3 mm. 

 Head from above more than twice as wide as long, temples strongly 

 rounded; eyes slightly divergent below, slightly shorter than greatest 

 width of face; malar space about as long as basal width of mandible; 

 clypeus little more than half as long as interfovcal line, very weakly 

 rounded at apex; interfoveal line little longer than foveo-ocular line; 

 face weakly elevated in middle, sparsely punctate at sides; anterior 

 orbits swollen; lateral ocelli about half as wide as postocellar line, 

 the latter about one and one-half times as long as ocell-ocular line; 

 occipital carina narrowly interrupted in middle. Thorax rather 

 slender, propodeum declivous beyond middle, but reaching beyond 

 middle of coxae, pronotum laterally deeply impressed and strongly 

 puntate; mesoscutum coarsely punctate, notauli strong; scutellum 

 more finely punctured without lateral carinae; mesosternum and 

 mesopleura coarsely, densely punctured except small polished area 

 immediately below wings; metapleura more finely, sparselj'' punc- 

 tured; propodeal carinae strong, areola and petiolar area separated, 

 the latter slightly the longer; apical areas transversely ruguloso, 

 areola and basal lateral areas sparsely punctate, other areas densely 

 punctate; stigma half as wide as lang, radius at apical third, second 

 discoidal cell scarcely a third as wide at base as at apex; nervellus 

 strongly antefurcal, not broken; hind legs slender, basitarsus three- 

 fifths as long as tibia and about as long as other four joints united. 

 Abdomen not quite twice as long as head and thorax, first and second 

 tergites subequal in length and together shghtly longer than rest of 

 abdomen; petiole with carinae strong to base, ventral edges of ter- 

 gites separated, parallel, not inclosing sternite, postpetiolo elevated 

 shghtly above level of petiole; second tergite between five and six 

 times as long as wide at base, its sides almost parallel, longitudinally 

 striate; tergites beyond second strongly compressed; ovipositor 

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