CICIKDELIDiE. 



(in C. davisoni it is quite truncate), and the central portion, which 

 in the last-named species is somewhat sloping, is fiat and even ; 

 the elytra, moreover, have no white spots and are longer, more 

 parallel-sided, and have the apex and the whole disc natter, being 

 more closely sculptured throughout, with the exception of the 

 marginal portion, which is more finely, though scarcely more 

 sparingly, punctured than the disc; the margins are, as a whole, 

 more sparingly punctured than in C. davisoni, being sloping and 

 obscurely cyaneous, as in Proihyma and Odontochila ; the series 

 of larger punctures near the suture is a little thicker than in 

 (J. davisoni, and punctures of the same character are irregularly 

 scattered here and there over the elytra; the lateral portions of 

 the pro- and meso-sternum as far as the coxa3 are sparingly pilose, 

 whereas in the preceding species they are without hairs, and the 

 whole of the episterna of the metasternum are more or less 

 sparingly and coarsely punctate-pilose ; the anterior margin of the 

 metasternum is narrowly, and the lateral portion broadly, punctate- 

 pilose, as well as the exterior half of the posterior coxae ; the femora 

 are coppery, shot with a greenish aeneous reflection and clothed 

 with testaceous hairs ; the upper surface is obscurely coppery red 

 and dull, whereas in C. davisoni it is browner and less coppery; 

 the punctures of the elytra are not greenish blue as in that species, 

 but concolorous with the disc, and the head and pronotum are 

 more plainly margined with purple ; the cheeks, the centre of the 

 prosteruum, the margins of the abdomen and part of the disc are 

 bright violaceous, and the episterna of the mesosternum are 

 obscurely aeneous, the whole of the metasternum and part of the 

 disc of the abdomen being variegated with brassy green ; tibiae 

 brownish testaceous, tarsi brownish, trochanters testaceous. 



Length 8-9 millim. (without labrum).

Horn (?. c.) speaks of the species as a very interesting one, 

 which with C. davisoni forms a compact group, deriving its origin 

 from the Frothy ma- Odontochila forms, and leading up to the 

 groups represented by C. chloropleura and viridicincta, rugosiceps 

 and corticata, and tetrastacta, which are all allied to C. germanica ; 

 he also appears to consider 0. davisoni as leading from O. prothy- 

 moides to C. belli, C. viridilabris and 0. triguttata. 



I have had the opportunity of seeing one of the few specimens 

 known ; superficially the insect is not unlike Cicindela belli, 

 W. Horn. 



Group 6. 



Only one species is included by Dr. Horn in this group ; it is 

 very small (6-7 mm.) and has the underside furnished with dis- 

 tinct, but scanty and not tomentose, pubescence at the sides ; the 

 sides of the pronotum are set with hairs or setae, and the genae 

 are scantily but distinctly pubescent. I have followed Dr. Horn 

 in retaining this species in a separate section, although it might, 

 perhaps, be referred to Group 5 as an exceptional case, like 

 C. imperfecta, which also has the genae more or less pubescent.
