Mexico, where dark-bronzed hues are the exception, whilst the reverse is the case in 

 Guatemala, where at Capetillo, judging from the very numerous specimens taken, 

 bronze-black is the general colour ; Capetillo examples are, moreover, distinguished from 

 the Mexican form, with very few exceptions, by the stria? of the outer side of the 

 posterior tibiae being much abbreviated, leaving a large apical space smooth or sparingly 

 punctured ; but there are all gradations in the extent of the smooth space. At Cerro 

 Zunil the prevailing colour is again different, the elytra being very dark greenish- 

 bronze, nearly black, and the head and thorax dark coppery; this form, which I 

 propose to call C. sejunctus, is also distinguished, but not quite in all the examples, by a 

 slight peculiarity of sculpture at the elytral apex, the acute submarginal carina not being 

 hooked behind, and also by the finer punctuation of the whole surface. As to the 

 general punctuation, it varies greatly both in strength and density, as in most of the 

 species of the genus, but the variation in this respect does not correspond with other 

 differential characters. 



The sculpture and tuberculation of the apical area of the elytra consists (1) in an 

 oblique row of about five oblong tubercles preceding an apical depression, the outer- 

 most of which is a short, but sharp, carina on the tenth interstice, (2) in a long 

 submarginal carina (on the twelfth interstice) sharply hooked at its apex, (3) in a 

 series of two or three tubercles, sometimes oblong, sometimes conical, and sometimes 

 connected as a wavy carina, on the apical part of the second interstice (i. e. the one 

 following the sulciform sutural stria), and (4) in a variable number of small rounded 

 warts on the intermediate space. This apical space is otherwise scored with sharp 

 striae, the interstices of which are flat and smooth. 



7. Cloeotus strigilateris. 



Parvus, 0. infantulo similis, sed differt elytris apice multituberculatis. JSTigro-aeneus vel laete seneus, politus ; 

 capite punctato, vertice laevi, fronte media tuberculato, cljpeo leviter sinuato ; thorace subtiliter (intra 

 latera grossius) punctulato ; scutello basi punctulato ; elytris subtilissime striato-punetatis, callo bumerali 

 vix prominente calloque elongato apud marginem dilatatum, carina submarginali valde elongata alta et 

 verticaliter flexuosa, carina apud interstitium 10 m acuta, area apicali 4- vel 5- tuberculata, interstitio 2° 

 interrupto, lateribus inter interstitium et marginem multistriatis ; tibiis posticis triangulariter dilatatis, 

 apice extus valde productis, compressis, extus irregulariter grosse insculptis.

Hab. Mexico, Cordova (Salle). 



The numerous strongly elevated carinae and tubercles of the apical area of the elytra 

 distinguish this species from C. infantulus and G. excisus, the latter having the usual 

 carinae very faintly elevated, and the former three continuous carinae, and being further 

 distinguished by the entire rounded edge of the clypeus. In one of the two examples 

 the apex of the hindmost tibiae is very widely and strongly emarginated, and the inner 

 angle (which carries one of the spurs) is very much shorter than the outer ; in the 

 other specimen the two spurs are nearly on the same level. The apical cross section
