ing the space between the edge of the segment and the medial raised portion, 

 the raised portion within this V and the raised portion of the lateral edge of the 

 segment are rather sparsely punctured with smaller regular punctures; third 

 segment with a basal crenulate groove that bifurcates in the middle of each side 

 of the segment at the anterior margin and thus forms two nearly equilateral 

 triangles, which are slightly impressed near the posterior margin, the re- 

 mainder of the segment is partially keeled medially with a raised line on each 

 side of which, for a short distance, the segment is rather confluently pitted or 

 rugulose beyond this medial rugulose space, to each side, the segment is first 

 irregularly punctured and then impunctate or minutely punctured and polished; 

 the fourth segment is polished and sparsely, irregularly punctured; the fifth, 

 sixth and seventh segments are polished and impunctate or nearly ; the ovipositor 

 is nearly as long as the abdomen and meta thorax combined. Black ; mesothorax, 

 upper half of pleura and abdomen red; the second and third segments partly 

 testaceous, the third and fourth segments brownish, at the junction of the meso- 

 pleura with the mesosternum is a castaneous line. Thinly sericeous with short 

 white pubescence, the pubescence on the metathorax longest.

Iphiaulax propinquus, n. sp. 



Female. — Length, 8 mm. Agrees very well with I. militarie, but differs in 

 the following important characters: Antennte fifty-six jointed or nearly. The 

 metanotum has a distinct median furrow ; the first abdominal segment is more 

 distinctly sculptured and has a median raised line on the posterior half; the sec- 

 ond segment is rather striated, and the triangular smooth space is reduced to a 

 semicircular space or lunule ; the ovipositor is as long as the abdomen and meta- 

 thorax combined. 



Type: University of Kansas. Type locality: Oak Creek Canyon, Ariz. One 

 specimen. August, 1902, F. H. Snow. 



Iphiaulax cinnabarinus, n. sp. 



Female. — Length, 6 mm. Structure very much as in militaris, with the follow- 

 ing differences : Face minutely rugulose, the clypeus differentiated and a supercly- 

 peal space outlined; parapsidal grooves practically absent; wings pale brownish, 

 nervureg and stigma dark brown. Antenna fifty-two jointed. Abdomen: The 

 elevated portion of the first segment not very high, rugulose, the innermost fur- 

 raws rather crenulate, the outermost furrows smooth; second segment rugose, 

 appearing rather as if confluently punctured, the diverging, oblique impressed 

 lines shallow aud similarly sculptured ; third segment with the bifurcation of the 

 crenulate suture not very distinct, the triangles formed by the bifurcation smooth, 

 punctured at the edge ; the fourth and fifth segments sculptured like the second, 

 somewhat coarser; ovipositor a little longer than the last two segments. Red, 

 almost like cinnabar; antenna?, except the scape above, tips of the mandibles, 

 ovipositor and tips of the feet, black.

Chelonus texanoides, n. sp. 



With the form of C. texanus, to which this species is related. 



Female. — Length, 5 mm. Head dull; face shining, face except the clypeus, 

 front, vertex, occiput and cheeks almost uniformly rugulose and somewhat stri- 

 ated ; clypeus smooth, closely punctured, the punctures small and not deep, an-
