(EDIONYCHIS. 433 



the intermediate basal spots united in the shape of a transverse band ; the same is the 

 case with the apical ones, which, after forming a transverse band, are joined by a short 

 sutural stripe to a triangular apical spot. All the specimens differ from the type in 

 wanting the spots on the thorax and the short lateral stripe near the apex of the elytra, 

 which are, however, present in the specimen from Venezuela contained in my own 

 collection. 



63. (Edionychis hondurensis. (Tab. XXIV. fig. 25.) 



Ovate, widened behind, fulvous ; antennae black, the first two joints testaceous; head and thorax fulvous, 

 impunctate ; elytra finely punctured, reddish fulvous, the basal and lateral margins broadly black. 



Var. Elytra entirely fulvous. 



Length 1^ line. 



Head impunctate ; the eyes not closely approached ; antennas with the third joint scarcely longer than the 

 second, the following joint also rather short, the three lower, and often the apical one, testaceous ; thorax 

 more than twice as broad as long, the sides moderately rounded, the anterior angles short and tuberculi- 

 form, the surface entirely impunctate, with a rather distinct groove on each side near the base ; scutellum 

 fulvous ; elytra extremely minutely and not very closely punctured, a transverse broad band at the base, 

 connected with a narrower longitudinal band at the sides, not extending to the apex, black or piceous ; 

 the first joint of the posterior tarsi very short ; claw-joint strongly swollen. 



Hab. British Honduras, Belize {Blancaneaux). 



This is one of the smallest species of the genus, the size of which, together with the 

 short second and third joints of the antennae, will assist in its recognition. 



64. (Edionychis violaceomarginata. (Tab. XXIV. fig. 23.) 



Oblong, convex, fulvous ; antennas and the anterior legs piceous ; vertex of the head dark blue ; thorax^ pale 

 fulvous ; elytra testaceous, finely punctured, the basal and sutural, as well as the lateral margins anteriorly, 

 violaceous-blue . 



Length 3 lines. 



Head impunctate at the vertex, with a few punctures near the eyes, the latter widely separated, the frontal 

 tubercles rather broad and trigonate, the lower part of the face testaceous, the labrum and jaws piceous ; 

 antennas short, black, the two basal joints stained with fulvous below, the fourth joint longer than the 

 third ; thorax narrow, more than three times as broad as long, the sides straight at the base, rounded 

 towards the apex, narrowly flattened, the anterior angles thickened but not produced outwards, the surface 

 entirely impunctate, with a shallow transverse basal groove ; scutellum black ; elytra slightly narrowed 

 towards the apices, convex, and nearly subcylindrical, finely and closely punctured, of a paler colour than 

 the thorax, the basal margin enclosing the shoulders, as well as the suture and the lateral margin anteriorly, 

 metallic dark blue ; the underside and the posterior legs reddish fulvous, the anterior ones piceous ; the 

 first joint of the posterior tarsi very short. 



Eab. Mexico, Oaxaca (Edge). 



The two specimens obtained are alike in every particular ; the blue colour of the 

 suture and lateral margin is extremely narrow, and, in the case of the latter, does not 

 extend further than just below the middle, while the colour of the suture extends 

 slightly round the apices of the elytra; the latter have their epipleurse testaceous 

 without, piceous within.
