yond the transverse basal. Mandibles testaceous, black at the apex. Cly- 

 peiis with a large fovea at the sides. Base of first abdominal segment 

 with a stout curved keel which extends shortly beyond the basal depres- 

 sion; in the center of the apical half is a longitudinal depression or 

 furrow. Comes near to G. tuberculifrons WaLsh. 



o96.S Lampronota aciculata sp. uov. 



Black, the legs except the hind tibiae and tarsi bright red; the palpi 

 testaceous. Wings hyaline, the stigma and nervures black. Female. 

 Length 8 mm.; terebra 4 mm. Taken at Gunnison, Colorado. 



Face and clypeus alutaceous, the latter vith a distinct border above; 

 front and vertex shining, indistinctly finely punctured . Mesonotum clo- 

 sely punctured, the middle lobe more distinctly and strongly than the 

 lateral. Scutellum roundly convex, smooth, shining, its apical slo])e and 

 })Ostscutellum strongly aciculated. Pro-and mesopleurae closely punctu- 

 red and more or less finely striated; the metapleurae finely rugosely punc- 

 tured. Metanotum finely, closely rugose, except on the apical slope where 

 it is sniooth and shining; there are two fine slightly twisted keels down 

 the center, a stout smooth keel down the center of the apex, with one 

 or two broken keels on either side; the sides are bordered by an irregu- 

 lar keel. First abdominal segment aciculatd at the base, smooth and 

 shining at the apex, the rest strongly aciculated and finely closely 

 striated; the basal half of the second segment finely aciculated, the rest 

 of the abdomen smooth and shining. Transverse median nerAaire placed 

 shortly behind the transverse basal; the recurrent nervure received at a 

 slightly greater distance than its length from the transverse cubital. Te- 

 gulae whitish yellow. Ventral segments broadly white at the apex. Meta- 

 pleural keel acute, not reaching to the apex. The apices of the second and 

 third segments are narrowly testaceous. Flagellum of antennae densely co- 

 vered with black pubescence; its first joint nearly f' long as the follo- 

 wing two united. 



Possibly this may be a form of L nrciiloiutlis Cr. The ovipositor is 

 certainly not as long as the abdomen and the sculpture is different. The 

 same form of coloration occurs with European species.

3984 Cidaphurus nigrolineatus sp. nov. 



Black, the face except for a line down its center, clypeus, labrum, man- 

 dibles except at the apex, the orbits, — the outer entirely — the inner line 

 not reaching to the top, a curved line at the sides of the front ocellus, 

 the two lines uniting into one and running down to near the bottom of 

 the front, palpi, two lines on the basal three fourths of the mesonotum, 

 narrow at the apex, thickened and dilated laterally outwardly at the 

 base, scutellums, their keels, median segment except l)roadly at the base.
