of three as in the first mentioned genus ; besides this they have 

 the shoulders of the elytra nearly always well marked, because the- 

 wiugs are well developed ; the first three joints of the anterior 

 tarsi are dilated in the male, and spongy-pubescent beneath. The 

 type of Tetraclia is Cicindela Carolina, Linne. The species be- 

 longing to Tetraclia belong to the New World, those placed under 

 Megaceplicrta to the Old.

Horn and Annandale (Catalogue of Asiatic Beetles in the Indian 

 Museum, Part i, p. 5) say that the geographical area of the 

 priority-form of this species, the only representative of the group 

 in "the Palasarctic and Oriental regions, is very remarkable : — • 



obscure violaceous reflections, 

 labrum and mouth-parts mostly 

 testaceous, mandibles large and 

 powerful, dark towards apex; head 

 large, about as broad as pronotum, 

 not contracted behind, eyes large 

 and prominent ; sculpture of 

 head very fine, coarsely nlu- 

 taceous, stronger near the eyes 

 where it is striate ; antennas 

 slender, testaceous, with long 

 setae at the apex of the joints ; 

 pronotum widest in front, sub- 

 cordiform, gradually narrowed to 

 the base, with two transverse fur- 

 rows (angulate in the centre) and
