colour, the base of coxae and more or less of the femora, black; 
wings hyaline, iridescent, the nervures and stigma black. ©. 
Lensth 5 mm; terebra 5 mm. 
Geylon (Nietner) Nr. 11927 and 11928. 
Opaque, alutaceous. Palpi black. The pubescence is longer and 
denser on the pleurae and metanotum than elsewhere. The keels on 
the metanotum, and the basal 2 abdominal segments are distinct. 
The suturiform artieulation is narrow, but clearly defined and is 
closely erenulated. In one example the rufous band on the 1% ab- 
dominal segment is very narrow, and the basal two-thirds of the 
2nd Hlack. 
Agathinae. 
Beognatha lineaticollis sp. nov. 
Black, shining, the labrum, base of mandibles, the base of 
prothorax, its pronotum broadly, and the pleurae more narrowly 
dark red; the 4 front legs rufo-testaceous, hind coxae black, the 
trochanters and femora dark rufous, the tibiae white to shortly beyond 
the middle, except for a pale brownish band near the base, the 
apical part black, the tarsı blackish; wings hyaline, the parastigma 
and stigma black, the nervures dark fuscous. Metanotum closely 
reticulated, the retieulations wider in the middle than on the sides, 
it being also more shining in the middle. Metapleurae closely, 
rugosely punctured. The base of the propleurae and the apex above 
closely, minutely punctured, the rest smooth, except for a few scatte- 
red punctures. Mesopleurae more strongly punctured, a smooth space 
below the wings; the lower part is depressed, almost furrowed, the 
depression rather wide, rounded below. Mesonotum trilobate, the 
middle lobe longer than wide, gradually narrowed from the base to 
the apex; it does not reach to the scutellum; the space at the 
apex is irregularly transversely striated. Scutellum more strongly 
punetured than the mesonotum; there are 4 stout keels on the basal 
depression. Abdomen very smooth and shining; the basal segment 
twice longer than wide, as long as the following 2 united; the 
basal 2 segments pale testaceous.
