spots and markings, a character specially mentioned by 

 the describer, who likens the species to C. aidica, Dej. 

 The hind trochanters are generally brassy ferruginous, 

 but they are sometimes clear red. The size given by 

 Chevrolat is 10^ mm., but the greater number of examples 

 measure 11 — 12 mm., or a little more. The labrum is 

 scarcely produced in the middle, unidentate in the 2 . 

 With some local variation it ranges over a wide area ; 

 Guatemala, Ceno de Plumas in Oaxaca {Hdr/e) ; Jala pa, 

 Chilpancingo, Iguala, and Mescala in Guerrero {H. H. 

 Smitli^ ; and Ventanas in Durango {Hoge). Its southern 

 varieties merge gradually into the following : — 



Var. Mellyi, Chaud., Bates, Biol. C.-A., Col., i., 1, 

 p. 8, t. 1, f. 7, in which the elytra is of a richer velvety 

 bluish black, and the head and thorax opaque coppery 

 red (Oaxaca, Guatemala), and 



Yar. ccdochro'ides, Motsch., in which the two (posterior) 

 marginal spots of the elytra have disappeared, and the 

 apical lunule is often reduced to a spot near the suture. 

 Chontales, Nicaragua. 



Cicindela hiidroplioJxi, Chevr. 



This species is very distinct from C. riifivcntris, in 

 general form, length, and convexity of the labrum, and 

 in the constant red colour of the hinder trochanters. It 

 seems to have nearly the same. range. The only addi- 

 tional lo( ality I have to record is Temax in North 

 Yucatan {Gaunter). Herr Hoge obtained a large series 

 of the beautiful variety 5-notata at Acapulco.
