CICIXDELIDvE. 



head is large and excavate between the eyes, which are very large 

 and prominent, and the vertex is long behind the eyes, gradually 

 contracted, and somewhat strangulate at the base ; the pronotum 

 is convex and smooth, globular or transversely globular, and the 

 elytra are parallel-sided, with the shoulders well marked and more 

 or less strongly raised on each side of the suture ; the legs are- 

 very long and slender. 



Genus THERATES. 



Therates, Latreille, Regn. Anim. (ed. 1) iii, 1817, p. 179; Lacordaire, 

 Gen. Col. i, 1854, p. 28. 



Type, Cicindela labiata, Eabr. 



Thirty-four species are contained in this genus, which range 

 from the Philippine Islands to New Guinea, and occur chiefly in 

 the islands of the Malay Archipelago, while three or four have 

 been described from Tonkin. The genus was not known to occur 

 in the Indian region until comparatively recently ; two species 

 only are recorded by Eleutiaux in his ' Catalogue of the Cicln- 

 DELiDiE,' published in 1892, but several species have since been 

 found by Doherfcy and others in Assam and Burma, and one is 

 recorded from Darjiling.
