ZOOLOGY OF THE FAR EAST. 
Family BELOSTOMATIDAE. 
Sphaerodema rusticum (Fabr.) 
1906. sphaerodema rusticum, Distant, \V. L., Fauna of British India, Rhynchota, III, p. 36, 
text-fig. 23. 
One adult and two immature specimens from a small pool or ditch at the edge of 
the lake, Tale Sap, Patalung.

Family CORIXIDAE. 
Micronecta merope, Dist.

p. 345, text-fig. 213. 
One specimen from the mouth of Patalung River at I^ampam, Tale Sap, 15 i-i6. 
Compared with Indian specimens identified by Distant. 
Micronecta lucina, Dist. 
1910. Micronecta lucina, Distant, W. L., Fauna of British India, Rhynchota, V (Appen- 
dix), p. 345, text-fig. 207. 
Two specimens from the mouth of the Patalung River at Lampam, Tale Sap, 
i5-i-i6. 
This apparently is a very variable species. The anterior fuscous line on the 
pronotum in the typical form is broken only in the middle, but in the Siamese speci- 
mens it is broken up into four or five round spots. This also is the case in two speci- 
mens taken at light at Madhupur, Bengal, which have been identified by Distant. 
The length of the head also does not always appear to be nearly half the width be- 
tween the eyes; in some specimens it is as long, if not longer, than the space 
between the eyes. 
Family NOTONECTIDAE. 
Anisops sp. juv. 
One specimen from a small pool or ditch at the edge of the lake, Tale Sap, 
Patalung, i3-i-i6.
