78 SOME HEMIPTERA HETEROPTERA FROM N. W. BORNEO. 
Both in structural characters and in colouring very distinct 
from the six previously known species. 
One of the most remarkable characters of this genus, not 
mentioned by Dallas and Distant in their descriptions, consists 
in the structure of the second ventral segment. It is longitudinally 
grooved in the middle and angularly projecting over the basal half 
of the third segment, and each side of the groove is raised in a 
strong tubercle. The spiracles in this genus are placed in the- 
lateral margins of the abdomen. 
4. Carbula trinotata H. Sch. — Lundu, Sarawak. 
5. Menida schultheissi Bredd. — Lundu, Sarawak. 
This species has been redescribed from the Philippines bv C.. 
Banks under the name Apines grisea. 
6. Rhynchocoris margininotatus Bredd. — Matang Load, 
Sarawak. 
7. Hypencha ophthalmica Stal. — Sarawak. 
I have forgotten to make a note of the exact locality. 
8. Hypencha alata Bredd. — Marapok Mts. on the borders be- 
tween Sarawak and British North Borneo. 
Fam. COFTOSOMIDAE. 
9. Spathocrates neuter n. sp. 
Ovate, moderately convex, somewhat shining, black, smooth 
and almost im punctate, only the scutellum remotely and extremely 
finely punetulate, rostrum and antennae pitchy testaceous, last an- 
tennal joint and legs piceous. Head one-third broader than long, 
notched at apex, somewhat convex, especially clypeus together with 
adjacent parts of juga, interocular space about five times broader 
than an eve, first and third antennal joints subequal in length, 
fourth as long as second and third together (fifth wanting), ros- 
trum almost reaching middle of fourth ventral segment, the whole 
last joint lying behind the posterior coxae. Pronotum with a 
shallow transverse median impression, more distinct toward the 
sides but not nearly reaching the lateral margins, and with a dis- 
tinct node at the humeral angles. Scutellum with a transverse 
basal area posteriorly terminated by a shallow broadly arcuate im- 
pression. Fifth female ventral segment with its apical sinuosity 
forming a right angle for the reception of the sixth segment, which 
in the middle is almost as long as the three preceding segments 
together. Length, 9 5.7 mm., width 3.8 mm. 
Mt. Penrissen, Sarawak. 
Allied to S. histeroides Walk., but larger, not aeneous, very 
much less punctured, and with narrower head, much longer rostrum, 
and much darker legs.
