telluin, basal half of second abdominal segment, the apex of the third, the fourth 

 and fifth almost entirely, the apices of the basal three ventral, of the fourth 

 more broadly, the band dilated broadly laterally, and almost the whole of the 

 fifth, yellow. The four front tibiae yellow, black behind, the posterior for the 

 greater part yellow. Wings hyaline, the stigma fulvous, the nervures paler 

 colored. £> . Length 10 mm. 



Antenual scape yellow, the flagellum brownish at the base and apex below. 

 Vertex strongly but not closely punctured, an oblique smooth space and a raised 

 longitudinal one in the centre behind. Front closely rugosely punctured; the 

 raised part above the antennae smooth. Clypeus and cheeks very sparsely punc- 

 tured. Basal half of mesonotum with large, deep, clearly separated punctures, 

 the apical almost impunctate. Scutellum with a curved row of punctuies in the 

 middle. Postscutellum smooth. Metanotal area with a wide crenulated furrow 

 in the centre; the part bordering it finely, closely, longitudinally striated, the 

 outerside punctured; the apical slope finely, distinctly, closely punctured; the 

 central fovea large, deep, somewhat triangular. Propleurse strongly, below 

 finely punctured, the lower part being also striated. Mesopleuiae coarsely punc- 

 tured, as is also the sternum ; the metapleuras less strongly punctured and 

 striated in the middle. Basal 3 segments of abdomen strongly, deeply, but not 

 very closely punctured. The 3rd cubital cellule, along the radius, distinctly 

 shorter than the 2nd, the 1st recurrent nervure received almost in the centre of 

 cellule.

This species appears to belong to Dr. Ashmead's genus Epiphi-

Dimorphomutilla ? luatha sp. nov. 

 Black, densely covered with lougish white hair; the calcaria and tarsal spines 

 white; wings hyaline, the nervures black ; radial cellule short, wide, the radius 

 forming almost a semicircle ; the 3rd transverse cubital nervure only distinct in 

 front, the 2nd recurrent nervure with the lower half only distinctly defined ; 

 the 1st transverse cubital nervure straight, obliquely sloped; the 2nd roundly 

 curved. Head wider than the thorax, the temples long, oblique, not much nar- 

 rowed ; the occiput almost transverse, the hind angles not acute but rounded. 

 Mandibles lougish, bidentate, the subapical tooth small. Front and vertex 

 strongly, distinctly punctured, the former more closely than the latter. Face 

 closely rugose, obliquely narrowed above to a point, forming a triangle. Anten- 

 nal tubercles rufous. First joint of flagellum wider than long, the second longer 

 than wide, longer than the third. Pro- and mesonotum somewhat strongly 

 punctured; the former more closely than the latter, the punctuies on it being 

 clearly separated. Metanotum reticulated. The upper part of the metapleurae 

 is irregularly reticulated, and finely, closely, longitudinally striated. Abdomi- 

 nal petiole becoming gradually wider from the base to the apex, in length 

 slightly more than the width at the apex ; at the base is a stout spine on either 

 side. The hair on the abdomen is long, but not forming bands; the pygidium 

 punctured towards the apex ; its apex rounded ; epipygium punctured, depressed
