SOME HEMIPTERA HETEROPTERA FROM N. W. BORNEO. 87 
cons, the four anterior coxae (except apical margin) blackish, the 
larger spines of the fore femora whitish. Head a little shorter 
than pronotum, anteocular part as long as postocular part with 
the eyes, unarmed beneath, postocular part very distinctly longer 
than broad, first antennal joint as long as head, second joint more 
than half as long again as first, third about one-third the length 
of first, fourth one-half longer than third. Pronotum twice longer 
than broad, humeral node angular and subacuminate at apex. 
Elytra ( $ ) reaching base of last dorsal segment, the membrane 
pointed at apex, its interior margin more or less sinuate before the 
tip. Abdomen ( <J ) with the last dorsal segment parallel, its 
apical margin broadly sinuate, the apical angles subacute. Fore 
coxae not quite reaching posterior margin of prosternuni; fore 
femora as long as the distance between anterior margin of eyes 
and base of pronotum, a little incrassated, about, eight times longer 
than broad. Length, S 16.8 mm.

This species comes very near to S. bipunctata Bredd. ( nec 
Walk.), but the fore and middle tibiae are not blackish at base and 
the last male dorsal segment is sinuate, not truncate, at apex. It 
is remarkable by having the membrane pointed at apex owing to 
the inner margin being a little sinuate before the tip. This charac- 
ter occurs, as noted by Stal, in some Neotropical genera of the 
Pygolampinae, but it is also met with in certain Old World species, 
although not mentioned in the descriptions. 
The Bornean S. brevicornis Bredd. is represented in the Sara- 
wak Museum by specimens from Baram. 
I suppose Distant has correctly identified S. bipunctata 
Walk, with the South Asiatic species which he regarded as belong- 
ing to S. baerensprungi Stal, but in Rhynch. Brit. Ind. V, p. 185 
lie wrongly places also S. bipunctata Bredd. as a synonym of that 
species. The species described by Breddin is totally different both 
in its structural and colour-characters, being narrower with much 
longer basal antennal joint, longer pronotum with acuminate humeral 
nodes, longer and less incrassated fore femora, and quite differently 
constructed last male dorsal segment. As to S. baerensprungi 
Dist., it will probably prove to be distinct from the true South 
European baerensprungi (of which Reuter in Ofv. Finsk. Vet. Soc. 
Forh. LV, 14, pp. 64 — 65 has given a detailed redescription), but 
whether the Asiatic species should bear the name incerta Sign., or 
bipunctata Walk., or a new name, can be decided only after a 
thorough re-examination of Signoret’s and Walker’s types. S. 
bipunctata Bredd. must be renamed unless bipunctata Walk, proves 
to be the same species.
