PENTATOMID/E,

leg. Like others of this division it is a predaceous insect, with a foreleg 
approaching in function and structure to that of the Mantidse. Canthe- 
cona furcellata , Wolff. (Plate LXXIV, fig. 2), is another form with some¬ 
what the appearance of Dolycoris indicus, but with the lateral angles of 
the pronotum spined. It is found upon crop plants in company with 
Dolycoris indicus, and Agonoscelis nubila, but is markedly predaceous 
and can readily be seen to suck out caterpillars and other small insects. 
We found it breeding abundantly in a plot of bariar (Sida rhombifolia) 
in which caterpillars were particularly abundant, and it is usually found 
breeding in such situations. In the intervals of such abundance of food, 
the imago appears to lead a precarious life of search for food. It has 
proved a very serious enemy to the cultivation of tussur silkworms in the 
open ; large numbers of the bugs came to the bushes on which the worms 
were and, in spite of constant destruction, managed to search out and kill 
many worms. It is probable they play a very important part in checking 
caterpillars generally. Andrallus (Audinetia) spinidens , Fabr., is a rarer 
insect, which feeds upon larvae of Thermesia rubricans and other cater¬ 
pillars, which is equally found among herbage and low crops (Plate 
LXXIV, fig. 5). Amyotea (Asopus) malabaricus, Fabr., is a bright red 
insect with black markings found occasionally upon cultivated plants. 
The life-history of Zicrona ccerulea is described by Kershaw and Kir- 
kaldy (Journ., Bombay Nat. Hist. Soc., XIX, No. 1, 1909) ; it is found in 
China to feed on the beetle Haltica coerulea, Oliv., the nymphs feeding 
on the larvae, the adults on the beetles. (The author’s use of Cimicidce 
for Pentatomidce in that paper will confuse the student unless he knows 
that Mr. Kirkaldy uses Cimicidce as the correct name for Pentatomidce 
and Khinophilos or Acanthia for Cimex, a practice followed by this 
author and a few others.) 
Tessaratomince.—Tessaratoma javanica, Thunb. (Plate LXXIV, fig. 
8), is a large brown bug over an inch long, found upon trees. Mr. Dixon 
has observed that it produces a loud shrill noise when seized. We figure 
it in its nymphal form when it is extremely flattened and leaflike 
(fig. 352) of the delicate red colour of many young leaves ; it is common in 
hill localities. The bug is remarkable as having a stridulating organ 
in both sexes. Its life-history and stridulating organ are figured and 
described by Kershaw and Muir (Trans. Ent. Soc., London, 1907, 
p. 253).
