CAMERON, FOSSORES. 235 



Tiphia erythrostoma, sp. nov. 



Black, Ihc clypeus, mandibles, palpi, tibia? and tarsi red, the middle joints of 

 Qagellum fuscous above; wings hyaline, the nervures pale fuscous, the sligma blackish; 

 propleurse aciculated, the mesopleuno strongly, but not closely punctured, the metapleime 

 finely, closely striated, weakly at Hie base, more strongly towards the apex. Pygidium 

 reddish in the middle, finely longitudinally striated throughout; the basal 2 segments of 

 the abdomen smooth, the others closely punctured. Basal half of pronotum strongly 

 punctured, the apical smooth; the mesonotum with large, deep, widely separated punctures. 

 Scutellum punctured at the base and apex, the apical rows stronger than the basal. 

 The 2nd transverse cubital nervure is roundly curved outwardly to shortly beyond the 

 middle, the apical part straight, slightly obliquely sloped. $. 



Length 78 mm. 



Mcrn low lands, December. One example. 



Tiphia cariuicollis, sp. nov. 



Black, the antenme, apex of clypeus, mandibles, palpi, tibia? and tarsi red; the 

 Qagellum of antenme largely infuscated above; wings hyaline, the nervures and stigma 

 black; teguUe large, conchiform, dark fuscous at the base, the rest pale testaceous. 

 Base of pronotum transverse, strongly keeled and with a crenulated furrow at the apex 

 of the keel. There are 3 keels on the metanotum, the outer two distinctly converging 

 towards the apex; the space between them irregularly, somewhat strongly transversely 

 striated. Propleime smooth; the mesopleurre in the centre finely, closely, almost rugosely 

 punctured; the metapleurte striated, more closely below than above. First abdominal 

 segment longish pyriform, distinctly narrowed at the base. The transverse median 

 nervure is received in the costal cellule before the transverse basal; the 2nd recurrent 

 nervure near the apex of the cellule. Temples short, the occiput broadly rounded, o 71 . 



Length 6 7 mm. 



Merit low lands, December. 



A slender species, readily recognised by the transverse, keeled base of pronotum, 

 by the large tegulte and by the longish, pyriform 1st abdominal segment. One specimen. 



Tiphia tiuctipeiiuis, sp. nov. 



Black, the mandibles broadly in the centre, the femora and the tibia?, red ; the 

 wings highly iridescent, fuscous violaceous, the hinder pair lighter in tint than the an- 

 terior; a faint hyaline cloud near the apex of the basal cellule, a narrow hyaline line 

 runs in front of the cubilus from the base to the apex, a similar one on the other side 

 of it, commencing near the 1st recurrent, and a curved one runs across obliquely the 

 middle of the 2nd recurrent. Metanotum opaque, covered with a white down; it has 3 

 keels all extending to the apex, the outer two slightly more widely separated at the base 

 than at the apex; the basal half of the metapleurse smooth and bare, the apical finely, 

 closely obliquely striated. $. - - Length 1-i mm.
