ZOOLOGICAL RESULTS OF A TOUR IN THE FAR EAST. 
AQUATIC HEMIPTBRA. 
By C. A. Paiva, Assistant, Zoological Survey of India. 
The water-bugs collected by Dr. N. Annandale, though few in number, con- 
stitute a very interesting collection. The specimens were all collected either from 
the inner lake of the Tale Sap system or from small creeks, pools or ditches on the 
shore of some part of the system. Among them there is a new species of Microvelia 
{Kirkaldya) represented by a few apterous specimens, one of which is a male. The 
majority of the remaining species are very widely distributed Oriental forms. 
Cercotmetus compositus has hitherto been known only from I^aos, and Halohates sexualis 
from the Siamese Peninsular province of Patani. All are true freshwater forms, 
except the last, which is probably estuarine. 
In all there are represented six families, nine genera and ten species, besides 
an immature form of another species. There are two species (2 genera) of Hydro- 
metridae, four species (3 genera) of Nepidae, two species (i genus) of Corixidae, while 
the Naucoridae and Belostomatidae have each a single species. The immature 
specimen belongs to the family Notonectidae. 
The most interesting feature of the collection is the fact that it includes speci- 
mens of a new species of the subgenus Kirkaldya (Genus Microvelia), which has 
hitherto been known only from North America.

One apterous male and four immature females, which I assign provisionally to 
the same species. From near shore of the lake among flood debris on the shore of the
