in the Gangetic valley and delta. Urostylis punctigera, Westd., and Uro- 
chela quadripunctata , Dali., are also found rarely in the plains. 
Acanthosomatince. —Are distinguished by the tarsi being two-jointed. 
Microdeuterus is represented by two species, sparingly found. Acan- 
thosoma, Sastragala and Anaxandra have the pronotal angles prominent 
or spined ; there are a number of species, widely spread and rare. Elas- 
mostethus recurvum, Dali. (Plate LXXIV, fig. 12), and others of this genus 
will also be found. 
Collecting. —Pentatomids are obtained by sweeping and beating 
vegetation, by ordinary searching on plants, among grass and low her¬ 
bage, on the bark of trees, under dead leaves and decaying vegetation. 
Some come to light. Rearing is easy only if the living plant can be pro¬ 
vided and maintained in vigour to supply the plant sap. When cap¬ 
tured they may be killed in a Cyanide or B. C. bottle and pinned through 
the scutellum or right hemelytron. Wings need not usually be set. 
What is principally required in this family is accurate observation 
as to the food-plants of the nymphs and adults ; very little is known and 
prolonged observation is usually required to determine what the food 
really is. Another interesting problem is that connected with breeding 
and seasonal appearance ; very little is known as to the seasons at which 
these insects breed or what checks their increase, and since all the common 
species can readily be determined with the aid of Distant’s volume, there 
is here a large field for observation.

Antennce inserted above a tine drawn from, the eyes to the base of the 
rostrum. Scutellum small. Rostrum not curved. 
In almost all cases, this family is immediately recognisable from its 
very distinctive facies. In doubtful cases, such as the red Serinetha , 
the characters must be carefully verified. They are insects of moderate 
to large size for the order, with a length of one quarter to one and a half 
inches. Some are heavily built and massive, others slender. Colouring 
is nearly always dull, the “dead leaf” colour very common in the large' 
forms, green or dry grass colour in smaller forms. Serinetha and a few 
others are brightly coloured. 
The head is small, deeply set in the large prothorax, with four-joint¬ 
ed and moderately long antennae, and a straight four-jointed rostrum
