tends beyond the apex of the penultimate joint. The niaik over tlie antenna i-s 

 continued as a line below, and the lower part of the eye incision is lined with 

 yellow. The tegulte in both sexes are for the greater part rufo-fulvous. 



I, at first, thought that this species might be 0. colon. Cress., but 

 that species, according to Mr. Cresson's Catalogue (Cat. of the Des. 

 Hym. of N. Am. North of Mexico, p. 288), is an Odynerus sensu 

 str. ; it has also a spot on the side of the second abdominal segment, 

 and the % has the clypeus " deeply notched at apex " which is cer- 

 tainly not the case with my species. 



'^^'''^Odynerus (Ancistroeerus) philelas sp. nov. 

 This species comes near to 0. fundatus Cress., which also occurs 

 at Fedor. The two may be separated thus : 



Legs dark ferruginous, black at the base; the oblique mark on tlie first abdo- 

 minal segment small, not extending to the middle of the segment ; the 

 mark on the second abdominal segment small f uiiflal us. 



Legs black, the apex of femora, tibise and tarsi bright lemon-yellow; the 

 oblique mark on the first segment large, wide, extending to the mid- 

 dle ; the mark on the second segment large philelas. 



Total length 10 mm. 9- Black; a curved mark on the top of the clypeus, a 

 small mark, dilated above, over the antennee on the front, one in the eye incision, 

 a narrow line on the base of mandibles, a short line behind the eyes, two large 

 marks on the base of thorax on the outer edge, a small square mark on the apex 

 of mesonotum, postscutellum, the sides of metanotum broadly, the mark extend- 

 ing on to the pleurae, a large mark, widest above, on the base of mesopleurae 

 above; a line on the apex of the first abdominal segment, largely, obliquely dila- 

 ted at the sides to the middle of the segment, where it is obliquely narrowed ; a 

 large, oval, transverse mark on the sides of the second near the base, a broad line 

 on the apex of the second and narrower ones on the apices of the following three, 

 lemon-yellow; the apex of the femora (the posterior only narrowly) and the 

 tibife of a brighter yellow color; the tarsi rufous, as also the apex of the tibiae 

 narrowly. Antenna; black, the scape yellow below. Wings hyaline, slightly 

 tinged with fulvous, the apex fuscous-violaceous. 



Clypeus longer than wide, the punctures longish, clearly separated, the apex 

 transverse. Front and vertex closely, rugosely punctuied. Prothorax and meso- 

 thorax closely, rugosely punctured. Metanotum rugosely punctured above, tlip 

 rest closely, obliquely striated, its sides rounded. Base of metapleiirse almost 

 smooth, the rest closely, finely punctured. Apex of first abdominal segment 

 slightly raised; the basal slope weakly punctured, compared with the rest; the 

 two parts not very clearly separated. The second segment is clearly longer than 

 it is wide at the apex, where it is more strongly punctured and has a coarsely 

 crenulated furrow behind the raised apex. The apical segments are closely 

 punctured.
