HYMENOPTERA OF SARAWAK. 97 



sides with a large tooth at the base and a smaller, more rounded, 

 one at the apex. Mesopleural depression punctured throughout. 

 Legs thickly covered with white pubescence, as are also the 

 breast and metapleurae. 



Megacolus rujitarsis, sp. nov. 



Black, the abdomen and tarsi rufous, the hind femora with 

 7 short teeth; a longish stout tooth or spire between the 

 antennae; the apex of scutellum projecting in the middle, its 

 apex almost transverse. 6 



Length 8 mm. 



Hab. Kuching. July. 



Head rugosely punctured, the punctures running into reti- 

 culations ; the frontal depression above stoutly transversely stri- 

 ated, with a stouter longitudinal keel down the centre; the lower 

 part with curved furrows ; the occiput irregularly longitudinally 

 striated. Metanotum with large, irregular reticulations. Pro- 

 pleurae smooth; near the middle is a wide, oblique furrow, bor- 

 dered below by a rounded keel ; mesopleurse covered with large, 

 round deep punctures; the central depression wide, slightly 

 narrowed below, smooth, obscurely striated above. The 3 basal 

 teeth of the hind femora are narrower and closer together than 

 the others. 



In colouration this species is identical with M. striolatus, 

 from which it may readily be known by the greater number of 

 teeth on the femora, by the transverse apex of scutellum and by 

 the frontal spine. 



Megacolus striotatus, sp. noy. 



Black ; the 1st abdominal segment and the tarsi testaceous, 

 the wings hyaline, narrowly streaked with fulvous, the nervures 

 and costa black ; hind femora with 5 teeth, the basal 3 short and 

 rounded; the apical 2 sharper and longer. $ • 



Length 8-9 ; terebra 3-4 mm.
