60 ENTOMOLOGICAL NEWS. [February, 



above, transverse striae within, below passing into a long median carina; 

 lateral faces striato-punctate, the striae transverse. Abdomen long trian- 

 gular, rather strongly constricted between the segments, coarsely punc- 

 tate, with four pairs of lateral spines; last segment trapezoidal, evenly 

 emarginate at tip. Color black; flagellum dark rufous; silvery pubes- 

 cence thin on face, sparse on thorax and abdomen. Tegulae rufous; tu- 

 bercles, squamae, widely separated spots on sides of abdominal segments 

 1-4, and two faint discal spots on segment 5, lemon-yellow. Legs black, 

 small spots at tips of fore and middle femora beneath, and a line on out- 

 side of all tibiae, lemon-yellow; tarsi rufous towards tips. Wings hyaline, 

 nervures quite dark. Length 7 mm. 



Fort Collins, August. This species is nearest cornutiis, with 

 which I at first placed it as a well-marked variety. It, however, 

 shows specific differences as above described. 



Oxybelus striatas n. sp. $. Thorax coarsely punctured, on mesothorax 

 more coarsely. Occiput up to back of posterior ocelli coarsely trans- 

 versely striato-punctate. Face very finely sparsely punctured. Ocelli 

 nearly normal, but showing a tendency towards the position in cornntus. 

 Vertex behind posterior ocelli with a distinct median tubercle. Prothorax 

 carinate, sharp angled at the sides. Mesonotum, scutellum and postscu- 

 tellum, carinate. Posterior margins of mesonotum and scutellum coarsely 

 rugose; squamae arising from lateral edges of postscutellum, rather sud- 

 denly narrowed to a point, which is strongly bent inward. Spine long, 

 narrow, slightly larger towards the tip. Metanotum above reticulated; 

 median area large, triangular, nearly smooth within, tip approximating 

 apex of metanotum and passing into a very short median carina; lateral 

 faces finely transversely striato-punctate. Abdomen broad oval, slightly 

 constricted between the segments, punctures of medium size, rather 

 sparse, especially on discs; with three pairs of lateral spines. Last two 

 segments very coarsely punctured, the last nearly rectangular, gently 

 emarginate at tip. Color black; pubescence of face brownish in certain 

 lights, on rest of body silvery ; flagellum deep chocolate. Tubercles, 

 spot on tegulae, squamae, tip of spine, and narrow fasciae on abdominal 

 segments 1-5 (slightly interrupted on 1-4), whitish. Posterior margins 

 of abdominal segments silvery. Legs black; foie tibiae and all tarsi ru- 

 fous, stripes on outside of all tibiae white. Wings hyaline, nervures 

 rufous. Length 6.5 mm. 



Fort Collins, August. This species is near subcornutus Ckll. 

 Among other differences, however, the scutellum is strongly 

 carinate, and the squamae are confined to the sides of the post- 

 scutellum. 



Oxybelus punctatiis n. sp. rj\ Closely related to striatns, but differing 

 .as follows : Mesothorax closely punctured. Extreme vertex coarsely 

 punctured. Occiput more strongly punctured, the striae not nearly so
