which probably serve a defensive purpose in association with the warn¬ 
ing colouration. 
The family is not a large one and the majority of the species are 
referred to the genus Cicindela. Atkinson’s Catalogue (Asiat. Soc., 
Bengal, LIX, 1890), lists 119 Indian species, Cicindela (74), Pronyssa 
(1), Megalomma (2), Dromicidia (1), Jansenia( 2), Therates (1), Tricon- 
dyla (5), Collyris (32), Tetracha (1). Maindron has added others (Ann. 
Soc. Ent., France, 1899, p. 379) ; Bates described Lewis’ Ceylon forms 
(Ann. Nat. Hist., VI, 16, pp. 68, 143, 199). A revision of Collyris 
will be found in Ann. Soc. Ent., France, 1864, page 483. 
Horn has described others (De. Ent. Zeitschr.), Cicindela (17), 
Collyris (10), Tricondyla (4), Therates (3), Heptodonta (2), Neocollyris (4) ? 
Calochroa (4), Euryoda (1), Derocania (1), Frothysa (1), are included in 
these later papers. Horn is now monographing the family in Genera 
Insectorum. Of these less than 20 Cicindela and one Collyris 
( C . distincta Chd.), occur in tropical India generally. Cicindela sex- 
punctata, Linn., is a striking species, found in the rice fields where it 
preys on the rice bug, Leptocorisa varicornis. It appears in August and 
September. C. grammophora, Chd. (Plate XVI, Fig. 12), is abundant 
in the rains in Behar, the commonest of the small species and very active 
on wet ground. C. i-lineata, F., is a conspicuous insect with four stripes 
of yellow on the elytra, found abundantly on the seashore of Western 
India ; in May, it feeds on the Halohates germanus so abundantly thrown 
up on the beach in the strong South-West wind and is a very conspi¬ 
cuous insect. Cicindela 8-notata, Wied., is common on the banks of 
rivers in the plains, a very gaudily coloured and noticeable species. 
C. 20-guttata, Hbst., with ten yellow spots on each elytron is abundant 
in rice fields with C. sexpunctata, Linn. 
Collyris includes mainly metallic blue tree-haunting species which 
are difficult to distinguish ; nearly all are forest species, some living on 
trees and bushes in the plains. Therates , like Collyris , has a long neck 
but is apterous, and includes robuster brown insects, found also in 
forests. The Cicindelidce are often of curiously limited distribution 
with regard to individual species; the common forms of one part of 
India are limited to distinct areas and there appear to be few species 
really widely spread even over the plains. A number of our subtropical
