On some Opisthoplatyinae (Hem., 
Reduviidae). 
By E. Bergroth. 
Opisthoplatys cinnamomeus Dist 
Prof. Baker has sent me a series of specimens (Nr. 14702 and 14703) 
of this insect from Sandakan (N. E. Borneo). Distant founded the genus 
Pangeranga upon it, but it cannot be separated generically from Opis¬ 
thoplatys Westw., the length of the first antennal joint being only of spe¬ 
cific importance in this genus. The corium is not »short and narrow», 
as Distant describes it, but slightly passes the middle of the tegminal 
costal margin and is not narrower than in the other species. The inte¬ 
rior cell of the membrane is said to be »transverse», but it is oblique 
and very much longer than broad. In the male the upper interocular 
space is very narrow, as indicated by Distant, but in the female it is 
conspicuously broader. 
Opisthoplatys pallens n. sp. 
Sordide ochraceus, modice longe et dense pilosus, pilositate antenna- 
rum longiore. Caput pronoto aeque longum, oculo (d) spatio intero- 
culari superiore vix triplo latiore, parte postoculari anteoculari aeque 
longa, a supero visa ab oculis ad collum cetero capite postoculari paullo 
brevius sensim rectilineariter fortiter angustata, articulo primo anten- 
narum capiti subaeque longo, plus duobus trientibus apicem hujus supe- 
rante, secundo primo paullo longiore, articulo primo rostri marginem 
posticum oculorum haud plene attingente, secundo primo paullo breviore. 
Lobus posticus pronoti antico duplo longior. Elytra ( 3 ) apicem abdo¬ 
minis longiuscule superantia. Abdomen ( 3 ) elytris clausis paullulo angus- 
tius. Long. 3 7,5 mm., inch tegm. 8,5 mm. 
Borneo (Sandakan, C. F. Baker). Nr. 14701. 
Not unlike the preceding species, but smaller, with less elongate post¬ 
ocular part of head, shorter collum, and shorter first antennal and 
rostral joint. 
Opisthoplatys paliidinervis n. sp. 
Testaceo-fuscus, breviter et modice dense pilosus, corio opacissime 
nigro-fusco, margine costali et apicali, venis atque angulo apicali (hoc 
late) pallidis, membrana fusco-nigra, venis basin versus leviter pallescen- 
tibus. Caput pronoto paullo longius, oculo ( 3 ) spatio interoculari supe¬ 
riore quintuplo latiore, parte postoculari quam anteoculari breviore, a 
supero visa ab oculis ad collum brevissimum rotundato-angustata, arti¬ 
culo primo antennarum capite paullo breviore, dimidio suo apicem capitis 
superante, secundo primo paruin longiore, articulo primo rostri medium 
oculorum attingente, secundo primo paullulo breviore. Lobus posticus 
pronoti antico minus quam duplo longior. Elytra ( 3 ) apicem abdominis 
attingentia. Abdomen ( 3 ) elytris clausis paullo latius. Long. 3 6,4 mm.
