Face and upper part of clypeus closely, strongly punctured ; tho 

 vei'tex and sides of front less closely and strongly punctured ; the 

 depressed centre of front strongly transversely striated above, 

 the middle with a wide furrow, keeled in the centre ; the lower 

 part smooth and shining. Temples wide, obliquely narrowed. 

 Face distinctly raised in the centre, the raised part bordered by 

 a depression. Thorax closely, regularly, distinctly punctured, 

 densely covered with short black hair; the apical slope of the 

 metanotum closely, strongly reticulated ; the metapleurse some- 

 what coarsely reticulated ; the hair on the segment is denser and 

 longer than it is on the rest of the thorax. Basal three segments 

 of the abdomen closely and strongly, uniformly punctured ; the 

 spiracles at the base of the clearly separated and dilated post- 

 petiole are prominent. The areolet is small ; it is not square ; the 

 recurrent nervure is received close to the apex ; the transverse 

 median nervure is interstitial ; in the hind wings it is broken 

 shortly below the middle. 



Stenaulax rufipes, sp. nov. 



Black, the legs, except the coxae and trochanters red ; the wings 

 fuscous violaceous, the nervures and stigma black. Face and upper 

 part of clypeus closely strongly punctured, the lower part of clypeus 

 smooth and shining ; the middle of the greatly depressed front is 

 stoutly, closely transversely striated, the middle with a stout 

 longitudinal keel ; the vertex is irregularly, weakly punctured. 

 Mesonotum and scutellum smooth. Base of metanotum weakly 

 punctured, the rest strongly, closely reticulated. Upper basal half 

 of propleurae weakly, sparsely punctured ; the rest stoutly, closely 

 reticulated. Mesopleurae closely, but not strongly punctured ; the 

 metapleurae strongly punctured at the base above, the rest strongly 

 coarsely, irregularly reticulated ; the upper part coarsely, obliquely, 

 widely reticulated-punctured. Mesosternal furrow wide, crenulated. 

 Metasternal keel large, curved. Abdomen smooth, impunctate ; it 

 is not much longer than the head and thorax united. All the 

 tibite and tarsi are thickly covered with short spines. The middle 

 lobe of the mesonotum is narrowed to a sharp point. 2 •
