base of the elytra, connected by a longitudinal lateral stripe with 

 another band across the middle, black. 



Length 3 lines. 



Head impunctate, with only a few punctures round the eyes, and 

 the usual transverse groove ; antennae entirely pale testaceous. 

 Thorax with the sides broadly flattened, and the anterior angles pro- 

 duced into a short tooth, surface impunctate; scutellum testaceous; 

 elytra rather convex, distinctly margined, minutely punctured 

 throughout, of the same colour as the thorax, with a transverse sub- 

 quadrate black band at the base, the posterior margin of which is 

 obliquely cut, and including a small spot of the ground-colour ; a 

 narrow lateral stripe connects this band with another fascia placed 

 at the middle of each elytron, which has the inner margin slightly 

 hollowed out, and is in some specimens almost connected along the 

 suture with the basal band. The presternum is distinctly raised in 

 shape of a ridge, and, like the entire underside and the legs, of a 

 pale testaceous colour.

14. CEdionychis instjlaris, sp. nov. 



Ovate, convex; obscure ferruginous below; antennas, tibiae, and 

 the two pairs of anterior legs black. Thorax and elytra pale testa- 

 ceous, the latter with two spots below the middle and the apex 

 violaceous black. 



Length 3 lines. 



Head with several deep punctures near the eyes, and a well- 

 marked transverse groove between the antennae ; lower half of the 

 face testaceous, the vertex and the labrum and palpi blackish pice-

 testaceous below. Thorax of the usual shape, with the anterior 

 angles produced in form of a short tooth directed outwards; surface 

 impunctate, pale testaceous ; scutellum black ; elytra widened be- 

 hind, rather convex, distinctly punctate, the punctuations diminish- 

 ing in depth towards the apex, but strongly marked in two longi- 

 tudinal rows below the humeral callus, of the same colour as the 

 thorax, an irregularly shaped small roundish spot below the middle, 

 and a still smaller one at the extreme apex of each elytron, of a 

 violaceous black colour. 



Hab. Mexico. 



Approaching in colour and markings (E. bipunctata, Chev. ; but 

 this species has no apical spot on the elytra, and the legs and breast 

 are black.

 flavous-testaceous ; the base and shoulder of each elytron, two spots 

 below the base, and two transverse fasciae behind the middle dark
