distinctly before the transverse median nervure. Eyes reaching to the base of 

 the mandibles on inner side. The tarsal comb long in $. The transverse 

 median nervure is received shortly behind the transverse basal, almost inter- 

 stitial. 



This species does not fit into any of the genera in Ashmead's Revision (Can. 

 Ent. XXXIV, p. 80 — 87). It comes nearest to the character given for Ferreola, 

 but that has the claws in the $ with a tooth and in the $ they are cleft, it 

 differing also in some other respects. The silvery pile on the base of the 

 abdominal segments may become rubbed off. 



SPHEGIDiE. 



Oxybelus latilineatus, sp. nov. 



Black, a line on apex of pronotum, tubercles, a large oblique, somewhat oval 

 spot on sides of scutellum, the base of post-scutellum broadly, the squamae, the 

 apex of central squama narrowly, and broad lines on the basal 4 abdominal 

 segments, pale yellow, the Pygidium rufous, the underside of the 4 front femora, 

 their tibiae except for a black line behind, the hinder except for a line on the 

 lower basal third and the greater part of the tegulae, pale yellow ; the tarsi 

 yellow, tinged distinctly with fulvous. Wings hyaline, the nervures black. 

 Central scutellar spine curved, about 4 times longer than wide, of equal width, 

 the centre depressed, the apex transverse ; the lateral spines rounded on outer 

 side, gradually narrowed to a point, longer than they are wide at the base, the 

 outerside depressed. Scutellum keeled down the middle. Metanotum areolated, 

 the arese large, the upper central smooth, shining, longer than wide, broadly 

 pyriform, the narrowed end below. Mesopleurse closely, rugosely punctured, 

 opaque ; the metapleurae with curved, distinctly separated stria?. Abdomen 

 strongly punctured throughout ; the pygidium appears as if longitudinally 

 striated and covered with a stiff depressed pile. Flagellum for the greater part 

 reddish brown. Mandibles yellow red and black. There are no distinct furrows 

 on the mesopleurse. $ . 



Length 4 mm. 



This species should be known by the areolated metanotum, the wide yellow 

 band uniting the lateral spots on the post-scutellum, and the fulvous pygidium. 



Oxybelus pictisentis, sp. nov. 



Black, antennal scape except above, a line, narrowed on inuerside, on the sides 

 of the pronotum, tubercles, tegulae, an oblique ; oval spot on the sides of scutel- 

 lum, the lateral squamae, apical half of spine, a semi-circular mark on the sides of 

 1st abdominal segment, a longer line, roundly dilated on the inner side at the 

 base on the sides of 2nd, 2 longish lines on the 3rd and a continuous one on the 

 4th, pale yellow. Anterior coxae black, the 4 posterior black above, yellow below, 

 fore femora red in front, black behind at the base and above, the black line gra- 

 dually narrowed towards the apex, the apex below it yellow, the 4 hinder red, 

 the middle with the apical half broadly yellow ; the tibiae and tarsi yellow, the 

 middle tibiae broadly, the posterior at the apex behind black ; hind spurs 

 fulvous. Lateral squamae large, broad at the base, gradually narrowed to a fine
