three segments deep, wide ; the keel on the second reaches to the 

 base of the apical fourth, becoming gradually narrowed from the base 

 to the apex. 



A specimen in my collection is only 12 mm. in length, and the 

 hyaline clouds on both wings are indistinct, being suffused with 

 fuscous. 



The Group of I. haaimactdo. 

 Black ; the abdomen red, short, broad, closely rugosely punctured, with deep, 

 wide striated furrows on all the segments ; there is no distinct area on the base 

 of the second segment.

 lied ; the head, marks on thorax, and legs black ; the wings dark fuscous, the 

 costa and stigma orange. The second segment of the abdomen rugose or 

 striated. 



The black legs distinguishes this group from the pictus section, the 

 reddish thorax from the basimacula one. 



Iphiaulax meridionalis, sp. nov. 



Red; the antennae, head, mandibles, palpi, pro- and mesosternum, 

 three large marks of almost equal length, the basal wider, roundly 

 narrowed towards the apex on mesonotum, a mark on the meso- 

 pleurae, tegulae and legs, black. Wings dark fuscous, the stigma 

 red. ? . 



Length 11 mm. ; terebra 8 mm. 



Cape Colony. Worcester Distr. 



Head and thorax smooth ; the abdomen with the centre of the first 

 and the second strongly, longitudinally striated ; the basal two 

 transverse furrows wide, deep, strongly crenulated ; the other basal 

 and apical segments smooth. Antennal scape of equal width, three 

 times longer than wide. Temples nearly as long as the eyes, rounded 

 behind. Apical abscissa of radius longer than the basal two united ; 

 the recurrent nervure is received in the apex of the first cubital cellule, 

 which has an oblique narrow hyaline cloud. 



There is no defined area or keel on the base of the second segment, 

 which is raised somewhat broadly and striated closely longitudinally ; 

 the lateral raised tubercles are much wider than long, becoming
