puncturation of the body is strong and close ; there is a distinct, curved tooth ou 

 the top of the hiud coxae near the base. 



New Mexico, Santa Fe District. In coloration this species is not 

 unlike A. philetas Cam., except that philetas has the clypeus black 

 with a yellow line on the top ; it is, however, a much stouter, broader 

 form with the 1st abdominal segment shorter, cup shaped, gradually 

 rounded from the base to the apex, broader than long, while in the 

 present species it is longer than broad; in it too, the apex of the 

 post-scutellum is transverse, not rounded; the base of the 1st ab- 

 dominal segment has almost a neck, showing an approach to Nortonia. 

 A. {Nortonia f) acanthopus Cam. is not unlike it, but is more slenderly 

 built, wants the oblique lines on the 1st abdominal segment, and the 

 clypeus is black except above. 



Ancistrocerns Foxeanus sp. nov. 



Black, the clypeus, an irregular line on the lower part of eye orbits, a small 

 squarish mark over the antennae, a short line ou the top of outer orbits, a large 

 mark, rounded and narrowed behind, on the prouotum, a conical mark below the 

 tegulfe, basal half of post-scutellum, a line ou the top of the 1st abdominal seg- 

 ment, narrowed laterally, a broader one all round the apex of the 2nd, narrower, 

 more obscure, lines ou the 3rd and 4th and an irregular spot on the sides of the 

 2nd, bright lemon-yellow. The apices of the four anterior femora, the tibiae and 

 tarsi yellow, the tarsi tinged with rufous; tegulse brownish red. Wings hyaline, 

 iridescent, the radial cellule fuscous violaceous; the stigma and nervures black. 

 Apex of 2nd abdominal segment strongly reflexed, a strongly crenulated furrow 

 behind. %. Total length 7 mm. 



Clypeus as wide as long, strongly, but not closely punctured, the apex with a 

 semicircular incision. Base of thorax transverse, with clearly defined lateral 

 edges, but not toothed. Apex of post-scutellum transverse. Sides of metanotum 

 blunt, rugosely punctured, the centre depressed, irregularly striated and punc- 

 tured. Apex of 1st abdominal segment smooth, slightly raised, behind this 

 smooth part is a strongly, deeply punctured border. The 2nd abdominal segment 

 is as long as wide and is slightly narrowed at the base. Antenual scape yellow 

 below, the flagellum stout, black, the hook brownish, stout, narrowed towards the 

 apex, which reaches to nearly tlie apex of the 11th joint. On the lower outer 

 lateral edge of the metanotum is a stout, unequally bifid spine. 



Sunbury, Pa. Belongs to Saussure's Section B, h. It cannot 



well be confounded with any of the few species known of that 



group. 



Aiicistrocerus quebeceiisis sp. nov. 



Black, the head, thorax and base of abdomen densely covered with long hair, 

 that on the head distinctly longer than it is on the thorax ; the sides of the meta- 

 notum margined by a stout keel ; the clypeus, labrum, mandibles, except at apex, 

 underside of antennal scape, a line on the top of 1st abdominal segment, and 

 broader lines on the following all round, pale yellow, almost white; the tibiae and
