CEDIONYCHIS. 421 



<E. bipunctata agrees in every particular with Von Harold's diagnosis. Some varieties have 

 the elytra, with the exception of the small apical spot, entirely testaceous, but the black 

 base of the head and the black scutellum seem constant. I must now refer to this species 

 my (E. insularis, in which the underside is ferrugineous, but the other characters the 

 same ; Chevrolat not mentioning the small apical spot, which probably was absent in the 

 type, made me think my species was a distinct one. The many intermediately marked 

 specimens now before me prove the great variability of (E. bipunctata.

Several similarly-coloured species to this have been described, and it is quite pos- 

 sible that the present one, which seems to be subject to more or less variation in colour, 

 is but another form of one or the other older species, of which, in many instances, 

 types must be compared for a certain identification. It is probable that (E. plebeja, 

 Klug, and the manuscript names of (E. dispar and (E. generosa, Chevr., refer to the 

 present insect. The large brown patches of the elytra change in some specimens 

 into dark bluish or black, and the transverse space dividing them varies a good deal 

 in width,- as do the spots themselves, which, however, never touch the lateral margin. 

 <E. honesta, Illig., and (E. humilis, Illig., seem also to be closely allied species, but the 

 former is described as having the second band of the elytra extending to the lateral 

 margin, which is not the case in (E. godmani, and the apices of the posterior femora 

 black, and (E. humilis with having a black spot on the middle of the elytra. 



36. (Edionychis illigeri. (Tab. XXIII. fig. 21.) 



FLavous ; base of the head and the intermediate joints of the antennae black ; thorax and elytra impunctate, the 

 latter with a broad transverse band at the base and a narrower one below the middle black. 



Length 3 lines. 



Head black, shining, impunctate, with a single puncture near each eye, the space between the latter not broader 

 than their diameter, with a deep transverse groove, the lower part of the face testaceous, the three lower 

 and the three terminal joints of the antennae testaceous ; thorax fulvous, the anterior and posterior margins 

 straight, the anterior angles scarcely visibly toothed, the surface impunctate ; scutellum fulvous ; elytra 

 impunctate on the dark part, scarcely punctured on the lighter portions, the anterior band extending to 

 nearly their middle, and separated from the posterior one by a narrow testaceous vitta, the posterior band 

 situated directly below the middle and narrower than the anterior one, leaving the apex broadly testaceous, 

 as well as the extreme lateral margin ; the posterior femora with a small piceous spot at their apices ; the 

 first joint of the posterior tarsi not longer than the second.
