black bands as well as three basal and two apical spots ; in varieties from Cuernavaca 

 all the elytral bands are separated into spots placed transversely (3, 4, 4, 2), in others 

 the apical spots are wanting, as well as the thoracic band, but structural differences I 

 cannot see ; the legs are generally fulvous and the underside piceous, but sometimes 

 the reverse is the case, and several intermediate degrees in regard to the pattern of the 

 elytra and the colour of the underside are before me, thus proving the variability of the 

 species. Mr. Champion obtained nearly forty specimens of the same or an extremely 

 closely allied species, in which the underside and legs are nearly always dark and the 

 thorax rather narrower and more shining, without any dark markings ; but as all the 

 other characters seemed to be the same, I think the Guatemalan specimens may safely 

 be considered as identical with or as a local variety of the Mexican form.

 Hab. Mexico \ Michoacan (Flohr). 



This little species cannot be mistaken for any other on account of the position of the 

 spots, notably the one surrounding the scutellum. Two specimens from Mexico, as 

 well as two others kindly given to me by Mr. Flohr, are contained in my collection. 



59. (Edionychis signata. 



Subdepressed, testaceous ; intermediate joints of the antennae black ; thorax impunctate ; elytra extremely 



finely punctured, a dentate band before, another at, and a third behind the middle, fulvous, the shoulder 



with one, the lateral margin with two spots. 

 Var. a. Elytra with the posterior band absent ; each elytron with two extra spots, one before, the other behind 



the middle, the bands margined with piceous. 

 Var. b. No elytral bands ; each elytron with seven black spots, four placed obliquely anteriorly, a larger one 



below the middle, one at the lateral margin, and another near the apex. 

 Length 2-2| lines. 

 Head impunctate, with the exception of a few very fine punctures near the eyes, the latter rather closely 



approached ; antennae, with the first five or six and the two terminal joints, testaceous, the others black ; 



thorax impunctate. 



Hab. Mexico, Tuxtla, Cordova (Salle) ; British Honduras, E. Hondo, R. Sarstoon 

 (Blancaneaux) ; Guatemala, Chacoj, Chiacam, Sinanja (Champion). 



I have taken the banded form of this apparently very variable species for the type : 

 these bands have the black spots of the varieties more or less indicated at exactly the 

 same places ; in others spots and bands alternate till the latter entirely disappear, thus 

 proving the variation and identity of all these forms. 



60. (Edionychis conspurcata. (Tab. xxiv. fig. 8.) 



Ovate, slightly widened behind, black or piceous ; head closely punctured, above testaceous ; elytra wrinkled, 

 more or less costate, two transverse strongly dentate bands, a spot at the shoulder and another near the 

 apex of each elytron, black.
