120 HYMENOPTERA OF SARAWAK. 



lum rounded, clearly separated, not furrowed or tuberculate in 

 the middle. Metanotum closely, distinctly and deeply punc- 

 tured, the punctures appearing to form reticulations in places ; 

 there is an oval fovea in the centre near the end of the upper 

 part ; the apical slope in the centre above projects, the projec- 

 tion being broader than long ; the part below it is slightly de- 

 pressed ; the spiracles are bordered behind by a deep, curved 

 furrow; the sides of the apex of the metanotum are bordered 

 by a deep, curved, crenulated furrow, Abdominal petiole near- 

 ly twice the length of the hinder coxae, curved, irregularly punc- 

 tured above, on either side of a shallow longitudinal furrow. 

 The 3rd joint of the antennae is slightly longer than the basal 

 two- joints united ; the 4th is about one fourth shorter than it ; 

 the latter is shorter than the 5th. The 1st and 2nd transverse 

 cubital nervures are obliquely sloped, parallel ; the 2nd cubital 

 cellule is clearly longer than wide ; the 3rd cubital cellule is 

 much narrowed in front, being there not much longer than the 

 space bounded by the 2nd transverse cubital and the 2nd re- 

 current nervures ; the 1st recurrent nervure is received about 

 half the length of the third abscissa of the radius from the 2nd 

 transverse cubital, the 2nd about its length from it. The trans- 

 verse median nervure is not quite interstitial ; the neuration 

 being very similar to that of S. mnbrosus, cf. Kohl, Ann. K.K. 

 Natur. Hofmus. V. Taf . VIII. f. 10. Claws bidentate, the basal 

 slightly longer and thinner than the apical. The labrum is 

 broadly rounded, neither toothed nor keeled. The 3rd to 5th 

 ventral segments are roundly incised, the incision on the 5th 

 being deeper than on the others ; the last ends in a sharp point 

 and is covered with long fulvous hair. The abdominal petiole 

 is shorter distinctly than the hinder tibiae, being almost of the 

 length of the hinder metatarsus. 



Should be readily recognized by the red apical segments 

 of the abdomen from the known Indian and Malay species. In 

 this respect it agrees with S. con/rater Kohl from New Britain 

 with which it cannot well be confounded. Sphex Franzi Cam. 

 Ann. Mag. Nat.- Hist.* April 1902, 246 from Borneo has the ab- 

 domen ferruginous, except the petiole and the wings are fus- 

 cous violaceous.
