Cam., lives parasitically in the nests of Myrmecocystus viaticus in 

 Algeria. 



Stibulaspis fortisteiata, sp. nov. 



Blue with brassy and dark purple tints ; the apex of femora, 

 tibiae, and tarsi pale testaceous, the lower half of the abdomen rufo- 

 fulvous ; antennae black ; the wings clear hyaline, the nervures 

 pale. ? . 



Length 5 mm. 



Natal. Durban. 



Head from the ocelli to the clypeus longitudinally, closely striated, 

 the striae becoming weaker below ; the raised centre of the face 

 transversely striated ; the clypeus smooth and narrowed above, 

 transversely striated below. Mandibles dark purple. The fourth to 

 ninth joints of the antennae are stoutly produced above ; the serra- 

 tions broad at the base, becoming gradually narrowed towards the 

 apex. Malar space almost twice the length of the eyes ; it is stoutly 

 striated ; the striae are curved. Mesonotum stoutly, transversely 

 striated ; the striae sharp, clearly separated. Scutellum similarly but 

 longitudinally striated; the striae somewhat stronger and more widely 

 separated ; they converge towards the apex ; the two apical teeth 

 are united at the base, stout, slightly diverging ; about three times 

 longer than thick, the apex rounded. Metanotum closely reticulated 

 in the middle ; the sides irregularly transversely striated. Pleurae 

 longitudinally striated, the striae sharp, clearly separated ; the upper 

 part of the propleurae closely reticulated. The dorsal part of the 

 abdomen is dark blue to near the apex, which is rufo-fulvous. 



Stibulaspis atropurpurea, sp. nov. 



Head and thorax blackish purple, the abdomen black with a faint 

 bluish tint ; antennae black ; legs black, tinged with purple ; the 

 apex of femora, tibiae, and tarsi testaceous; wings hyahne, the 

 nervures pale fuscous. $ .

Natal. Estcourt. 



Face opaque, alutaceous, bare, a broad depression or furrow in 

 the centre ; clypeus finely irregularly transversely striated ; malar 

 space irregularly, finely, obliquely striated ; it is about one-half 

 longer than the eyes. Sides of vertex and front finely longitudinally 

 striated. Pro- and mesonotum transversely, regularly striated ; the
