2. Epirhyssa albolineata sp. n. 

 Bivak Island, September. 



Black, shining, a broad line on the inner orbits commencing at the ocelli and extending 

 to near the bottom of the eyes, narrowed, almost interrupted, at the antennae, a similar line 

 on the outer orbits, commencing near the top and extending to the outerside of the malar 

 space, a broad line across the scutellum, commencing at the top of the basai dépression and 

 reaching to less than its own width from the apex, a broad mark on either side of the apical 

 slope of the metanotum, narrowed and curving round as a narrow line round the top, the two 

 almost uniting, tubercles, a narrow line running down from near their base, an oblique conical 

 line on the metapleurae, and narrow lines on the apices of the basai 5 abdominal segments, 

 that on the ist narrower and not reaching to the outer edges, the apical two narrowly inter- 

 rupted, white; legs black, the anterior coxae, a longish, not very broad line, narrowed at 

 the apex, on the middle and almcst the apical two-thirds of the hinder, white; the fore femora 

 and the apical three-fourths of the middle, the 4 front tibiae and the apex of the hinder, 

 rufous; the calcaria and the palpi pale; wings hyaline, the stigma and nervures black, a 

 fuscous violaceous cloud at the apex, commencing close to the transverse cubital nervure and 

 extending to the end of the radius, the part beyond being white; the transverse médian 

 nervure is received shortly, but distinctly beyond the transverse basai ; the transverse médian 

 nervure in hind wings is broken quite near the top. Ç. 



Length 17 m. m., terebra 27 m. m. 



Smooth and shining, except the usual transverse striae on the mesonotum ; the striae 

 are strong; the basai slope is smooth; the parapsidal furrows are clearly defined, converge 

 towards the middle, which they do not reach. The apex of the propleurae is weakly punctured, 

 the base of the mesopleurae much more closely and strongly so, as are also the metapleurae 

 but still more strongly, so. Clypeus smooth ; there are some curved striae on eitherside of 

 the top; the middle on the lower half is bordered by wide furrows. The first abdominal 

 segment is about one quarter longer than the second. 



Certonotus, Kriechb. 

 1. Certonotus lorentzi sp. n. 



Bivak Island, January. 



Black, the face, clypeus, labrum, a line on the upper inner orbits not very broadly to 

 the lower ocellus, the outer orbits except for a broad line on the malar space, on the lower 

 three-fourths, a large mark, narrowed to a point, in the middle below, on the propleurae 

 above, not reaching to the apex, a mark, longer than wide, obliquely narrowed at the base, 

 rounded at the apex, which is narrower slightly than the base, a line round the apex of the 

 metanotum, narrower and trilobate at the base, a line on the mesopleurae, immediately below 

 the wings, a mark on the base above, its lower half distinctly narrower than the upper, the 

 sides of which are obliquely narrowed below, the top bluntly rounded, the bottom transverse, 

 a large oblique mark, twice longer than wide, slightly narrowed towards the apex, which is 

 obliquely truncated, the base bluntly rounded, and marks on the sides of the 2 n <l and following 

 abdominal segments, bright yellow; the basai 4 longer than they are wide at the base and
