1880.] PHYTOPHAGOUS COLEOPTERA. 179 



Collected by Mr. H. Belt and Mr. Rogers. 



Types in Messrs. Godman and Salvin's collection and my own. 



27. CEdionychis salvini, sp. nov. 



Broadly ovate. Dark brown below, above flavous testaceous ; 

 antennae and base of head black ; elytra closely and rather deeply 

 punctate, flavous ; a subquadrate sutural spot surrounding the scu- 

 tellum, a narrow streak at the shoulders, and two short transverse 

 bands behind the middle bluish black. 



Length 4 lines. 



Hab. Zapote, Gruatemala, and Costa Rica. 



Head with a few deep punctures at the vertex, the latter black ; 

 lower part of face flavous, stained more or less with piceous ; antennae 

 black, the first joint slender, stained with fulvous below. Thorax 

 rather convex, the sides straight at the extreme base, from there to 

 the apex rounded ; the anterior angles much thickened and strongly 

 produced outwards ; surface finely but distinctly punctured. Elytra 

 convex, subparallel, strongly and closely punctured, flavous, spotted 

 with black ; the sutural spot is broadest at the base, its sides deeply 

 concave ; the apex nearly straight ; the shoulder-spots consist of a 

 short narrow streak, while the transverse postmedian bands do not 

 quite touch the sutural nor lateral margins, the apical spot being 

 rather round. Entire underside and legs ferruginous. 



Var. The basal spot of broad and round shape, separated at the 

 apex, the shoulder-spot wanting, and the transverse bands united 

 into a large round spot. This variety I also possess from Costa Rica. 



Collected by Mr. Champion. 



Types in Messrs. Godman and Salvin's collection and my own. 



28. CEdionychis steinheili, sp. nov. (Plate XVIII. fig. 9.) 



Broadly ovate. Piceous, above fulvous ; elytra distinctly punctured, 

 a broad transverse band at the base and a large patch below the 

 middle dark violaceous blue. 



Length 5 lines. 



Hab. Columbia. 



Head very minutely punctured ; encarpse and carina rather 

 flattened and broad ; antennae long, filiform, third joint double the 

 length of the second and half the length of the fourth joint, 

 piceous. Thorax transversely convex, sides broadly flattened and 

 slightly excavated ; lateral margins very round, narrowed from base 

 to apex ; posterior margin straight ; anterior angles produced into 

 rather large teeth of square shape ; surface closely but scarcely more 

 strongly punctured than the head. Scutellum fulvous. Elytra 

 wider at the base than the thorax, much widened towards the 

 middle, distinctly margined, closely and a little more strongly puncr 

 tured than the head, the dark blue bands not touching the lateral 

 margins. Underside and legs piceous, abdomen fulvous. 



At once distinguished from OH. bifasciata, Baly, by its large size, 

 the dark underside and antennae. 



Two specimens in my collection.
