182 SJOSTEDTS KILIMANDJARO-HERTJ EXPEDITION. 8: (5. 



black; the 2nd cubital cellule distinctly appendiculated ; the 1st transverse cubital nervure 

 slightly curved downwards; the 1st recurrent nervure is received at a greater distance 

 from the base than is the 2nd from the apex. Abdominal petiole as long as the tho- 

 rax; the 2nd segment bell-shaped, longer than it is wide at the apex. Clypeus a little 

 wider than it is long, narrowed above, the apex broadly rounded. $. 



Total length 8 mm. 



Kilimandjaro: Kibonoto, 10001300 m.; 23 April. 



Antennae stout, the 2nd joint twice longer than wide, the 3rd and 4th almost equal 

 in length. Head a little wider than the thorax, roundly dilated in front of the eyes, the 

 lower part of which, below the incision, reaches almost to the antennae; the puncturation 

 on the front and vertex strong and close; on the clypeus it is weaker and with the 

 punctures more widely separated. Apex of mandibles brownish. Base of thorax trans- 

 verse; the puncturation on the pro-mesothorax and basal two-thirds of scutellum strong 

 and close; the apex of scutellum and the postscutellum opaque, aciculated; the latter 

 with a distinct furrow down the centre. Metanotum shagreened, opaque, and with scat- 

 tered shallow punctures; the basal half with a distinct middle furrow, the apical slope 

 depressed in the middle, the sides thickly covered with silvery pubescence; metapleune 

 aciculated and finely, closely striated. 



The tf has the legs almost entirely black, the clypeus and basal half of man- 

 dibles broadly pale yellow; the apex of the clypeus is black and broadly rounded, the 

 sides being also black; the yellow pronotal mark is smaller than it is in the ; the an- 

 tennal hook stout, curved, reaching to the base of the llth joint; the 4 hind legs are 

 black; the fore tibiae and tarsi are testaceous; the yellow apical line on the 2nd abdo- 

 minal segment extends to the ventral surface; in both sexes there is a crenulated furrow 

 on the apex of the 2nd ventral segment. 



Labus annulipes sp. nov. 



Black, the clypeus except the sides and apex, the outer edge of the pronotum, a 

 spot on the base and apex of tegulae, the 4 anterior tibiae except on the anterior side 

 and the posterior to shortly beyond the middle, the black part below being obliquely 

 narrowed; the apex of the 1st and 2nd abdominal segment above and 3 lines (the cen- 

 tral the longer) on the apex of the 2nd ventral, pale yellow. Wings hyaline, the stigma 

 and nervures black; the 2nd cubital cellule distinctly appendiculated; the 1st transverse 

 cubital nervure curved downwards, the 2nd roundly curved towards the apex; the radial 

 cellule smoky violaceous, except for an oblique narrow space at the base. The antennae 

 much dilated at the apex; there is no hook, the last joint is broad, a little longer than 

 broad, its apex rounded, from it a pale raised keel runs along the sides to the 10th joint; 

 the basal joints are as in L. maculicollis, there is no proper antennal hook. a 71 . 



The abdominal petiole in the above described 2 species is much longer than it 

 is in the normal species of Labus, it showing a distinct approach to Zdltus. In this 

 respect it agrees with L.? nxierosti/lus, KOHL (Denkschr. d. Math.-Natur. Klasse d. K. K.
