NOTULAE ENTOMOLOGICAE 1921. 
extensa, cellula interiore antrorsum usque ad medium marginis interioris 
corii protensa, cellula exteriore plus quam duobus trientibus cellulam 
interiorem superante et pone hanc parallela. Abdomen fere orbiculatum, 
subaeque latum ac longum, elytris clausis latius, ventre disco convexo, 
medio percurrenter anguste carinato, lateribus deplanato, connexivo 
inferiore a disco ventris carina humili separato. Pedes simplices, postici 
quam medii paullulo magis distantes; tarsi biarticulati, articulo secundo 
primo brevi multo longiore. 
This genus should be placed near Apocaucus Dist. and Afrodecius 
Jeann., but it is very distinct from both in the structure of the head 
and pronotum. It has strongly developed semitransparent bucculae like 
those of the Tingidae and the postocular part of the head is near the 
base furnished with a rugose membrane which is directed backwards, 
simulating a pronotal collar; this membrane is bent down on each side, 
covering the upper and lateral parts of the neck and ending in a tooth 
immediately behind the bucculae. I have seen nothing like this structure 
in any other hemipterous insect. 
Gastrogyrus monophleboides n. sp. 
Glaber, impunctatus, obscure testaceus, elytris fulvo-ochraceis, dirni- 
dio eorurn posteriore inordinate fusconigro-variegato. Bucculae fere 
pellucidae. Articuli duo primi antennarum subtus longissime pallido- 
pilosi, priirm supra glabro, secundo ibidem breviter et parce piloso. 
Cellula exterior membranae a margine interiore quam ab exteriore paul- 
lulo magis remota. Abdomen pronoto paullo minus quam duplo latius. 
Long. 3 5,3 mm., inch tegm. 6,7 mm. 
Borneo (Sandakan, C. F. Baker). The unique type bears no dup¬ 
licate number. 
On Apocaucus laneus Dist. An nan dale has observed that it „closely 
resembles a Monophlebus on the wing.” This remark is certainly also 
relevant to Gastrogyrus.
