shoulders, the latter not quite touching the sutural or lateral margins, the small spot placed close to but 

 below the scutellum. 



Eab. Mexico, Playa Vicente, Tuxtla (Salle), Jalapa {Edge); Beitish Hondukas, B, 

 Hondo (Blancaneaux) ; Guatemala, Panzos, San Geronimo (Champion); Nicaeagua, 

 Chontales (Belt) ; Panama, Bugaba (Champion). 



The narrow black basal margin of the elytra and the transverse band placed below 

 the middle will not allow (E. tenuicincta to be mistaken for any other described 

 species. 



48. (Edionychis championi. (Tab. XXIV. fig. 18.) 



Pale testaceous ; the last six or seven joints of the antennae black ; head and thorax impunctate ; elytra finely 

 and closely punctured, two spots at the base (one at the shoulder, the other near the scutellum), and three 

 behind the middle (placed transversely), black. 



Length 3 lines. 



Eab. Panama, Volcan de Chiriqui (Champion). 



The two specimens obtained do not differ in shape from (E. tenuicincta or (E. hume- 

 ralis, with the latter of which they have the two obliquely placed basal spots in 

 common, but differ in having three spots placed behind the middle, the sutural one of 

 which is placed a little lower than the other two, thus giving a convex shape to the 

 line of position ; the want of the black basal margin and the extra shoulder spot 

 separate (E. championi from (E. tenuicincta. The position and shape of the markings 

 of these insects seem to me a better guide for their classification than the number or 

 colour of the marks themselves. 



49. (Edionychis inscripta. (Tab. XXIV. fig. 21.) 



Subdepressed, testaceous ; the base of the head and the four terminal joints of the antennse black ; thorax 

 impunctate ; elytra very finely punctured, a transverse band at the base (enclosing four testaceous spots) 

 and a narrow band behind the middle, black. 



Length 3 lines. 



Eab. Mexico, Jalapa (Edge). 



In shape and coloration this species resembles somewhat (E. transversalis, Jac., but 

 the design of the elytral markings is different. The entire posterior part of the head 

 is black and impunctate; the basal band of the elytra does not extend to the lateral 

 margin, and is interrupted by four elongate testaceous spots regularly placed; the 

 posterior narrow band is placed below the middle, extends to the lateral and, in most 

 cases, sutural margin, and is curved or convex in shape. 



50. (Edionychis hypocrita. 



Pale testaceous ; antennae with the four or six last joints black ; elytra impunctate, a transverse dentate band 

 below the base (including three or four spots), and another deeply angulate band below the middle, obscure 

 fulvous. 



Length 2f-3 lines.
