obliquely narrowed towards the apex, that on the 4* wider than long, its apex lengthened 

 on the outerside, that on the 5 th transverse, of equal width, reaching to near the apex, that 

 on the 6 th wider, narrowed on the outer side, the ^th with 2 spots, the inner small, conical, 

 the outer much larger, longitudinal, longer than wide, the apex of the segment narrowly 

 laterally, more broadly in the centre. The anterior legs rufous, the coxae and basai joint of 

 the trochanters yellow, the tarsi blackish ; middle and hind legs black, the middle coxae and 

 the hinder above yellow, the apices of the femora and tibiae rufous, as are also the spurs. 

 Wings hyaline, the apex narrowly clouded, the stigma and nervures black; the areolet is 

 narrowed in front, the nervures almost touching there, the récurrent nervure is received near 

 the apex; the récurrent nervure is obliquely bent backwards, the anterior half broadly rounded, the 

 hinder straight and more oblique. On the base of the metanotum are 2 wider than long, areae, their 

 outer side rounded, the inner longer, straighter and more oblique, except narrowly, at the base. Q. 



Length 20 m. m., terebra 17 m. m. 



The face is obliquely narrowed below the eyes ; there is an inner row of foveae, com- 

 mencing shortly above the middle; outside them and shortly below their commencement 

 are 2 foveae. Clypeus large, extending to the eyes, depressed and striated above, its apex 

 slightly rounded inwardly ; its sides are almost straight. Labrum nearly as long as it, rounded 

 at the apex, its top striated. Malar space as long as the labrum. The transverse médian 

 nervure in hind wings broken shortly above the middle. The process on the 8 th abdominal 

 segment has the apex narrowed and separated, this apical part being about 3 times longer 

 than wide, its apex bluntly rounded. The ist abdominal segment is distinctly longer than the 

 2nd. The antennae hâve the basai joints brownish, the scape marked with yellow. 



2. Certonotus foveatus sp. n. 



Bivak Island, January. 

 Black, the face except for a line down the centre above, reaching near to the middle, 

 more than twice longer than wide and rounded below, clypeus, labrum, a line on the inner 

 orbits of equal width, commencing opposite the hinder ocelli, the greater part of the outer 

 orbits, the yellow commencing near the bottom of the upper fourth, narrowed above and to 

 a less extend, below, a pyriform mark on the basai three-fourths of the pronotum, the 

 narrowed end at the base, a squarish spot almost in the centre of the mesonotum, the apex 

 of the metanotum, the mark distinctly narrowed in the middle, largely dilated on the sides, 

 a longish line on the top of the mesopleurae, a large, longer mark immediately below it, 

 bluntly rounded at the base, roundly narrowed toward the apex above, a large, oblique mark 

 below this, about two-and a half times longer than wide, bluntly rounded at the base and 

 apex and of equal width, a longitudinal triangular spot on the 2 n(i abdominal segment, a 

 transverse triangular one on the 3 rci , narrow transverse lines of equal width on the 4 th and 5 'h, 

 thèse reaching nearer to the middle, a larger, wider line, narrowed on the outerside, reaching 

 not quite so near to the middle and 2 square marks near the middle on the 6 th and a line 

 on its apex, commencing at the outer edge and reaching near to the middle, pale yellow. 

 Four front legs fuscous, the coxae and basai joint of the trochanters yellow, the apices of the 

 femora and tibiae rufo-testaceous, the hind legs similarly, but darker coloured, the coxae 

 black, largely yellow on the innerside above. Wings hyaline, the nervures and stigma black,
