264 MR. It. E. TURNER ON THE [Feb. 1 5, 



finely and very closely punctured, rounded at the sides, short and 

 steeply sloped posteriorly. Abdomen elongate, the segments con- 

 stricted near the base, the extreme base very finely punctured, the 

 apical portion more sparsely and coarsely punctured, with a large 

 smooth patch on each side near the apical margin ; the seventh 

 dorsal segment with a tubercle on each side at the apex, prolonged 

 between the tubercles into a short narrow process, which is as 

 broad as long and truncate at the apex. Hypopygium ending 

 in a long recurved spine. The position of the second recurrent 

 nervure is rather valuable, being received by the third cubital cell 

 from one-fifth to one-quarter from the base ; the division of the 

 first cubital cell is well marked, but not quite complete. 



Black, the two apical abdominal segments ferruginous red. 

 Wings hyaline, slightly tinted with fuscous, nervures black. 

 The ventral segments are fringed at the apex with white 

 pubescence. 



Length 14-15 mm.

2 . Differs from the female of aculeatus st. acutaugulus Turn, 

 in the shorter and broader head, which is rather less than half as 

 long again as broad in the typical form, and considerably more 

 than half as long again as broad in st. acutangulus . The mandibles 

 have a short blunt tooth on the inner margin.

<3 . Clypeus convex, narrowly produced and strong!}- porrect, 

 deeply and narrowly emarginate at the apex, the angles of the 

 emargination produced into short spines; closely and finely punc- 

 tured ; with an obscure median carina from the base to the 

 middle. Head and pronotum shining, shallowly and not very 

 closely punctured, the head slightly narrowed behind the eyes, 

 but broader posteriorly than the pronotum. Antenna3 inserted 

 as far from each other as from the eyes ; the interantennal pro- 

 minence very small and low, V-shaped ; a small longitudinal 

 depression halfway between the anterior ocellus and the base of 

 the clypeus ; antenna? a little longer than the thorax without the 

 median segment, the apical joints slightly arcuate. Anterior 

 margin of the pronotum strongly raised ; mesonotum and scu- 

 tellum closely punctured. Median segment smooth and shining 

 at the base, finely and very closely punctured rugulose beyond the 

 shining area which is divided by a very short longitudinal sulcus,
