DESCKIPTIONS OF SOUTH AMERICAN CHRYS0MELIN.T5. 193 



Head impunctate ; labrum flavous ; antenure dark fulvous, the basal two 

 or three joints j)aler, terminal joint longer than broad, extending to the base 

 of the elytra only ; thorax nearly three times broader than long, the sides 

 straight at the base, slightly rounded in front, anterior angles produced 

 forward, surface very remotely and irregularly punctured ; elytra with rather 

 regular strise of fine punctm-es, those at the sides geminate, the sutural, 

 lateral, and apical margins dark brown ; a similarly coloured broad band is 

 placed across the elytra before and another one below the middle, the 

 former band does not extend to the lateral margin, but the posterior one is 

 joined to it by a small point ; mesosteruum impunctate at the sides ; claws 

 simple. 



Hah. Pernambuco. 



Of this species two specimens are contained in my collection : 

 one is marked as described ; in the other the posterior band is of 

 much broader, more triangular shape, narrowed at the suture, 

 and does not touch the lateral margin ; the apical joints of the 

 anteunse in this specimen are also black instead of brown ; other- 

 wise there is no dift'erence. 



*S'. nigrozonata, IStal, seems a closely-allied species, but the 

 antennae, tibiae, and tarsi are described as testaceous, and the 

 elytra as " confusely punctured at the sides"; the abdomen is 

 also said to have two testaceous spots. 



Cryptostetha cyaneo-fasciata, n. sp. 



Metallic blue ; head and thorax opaque, impunctate ; elytra deeply and 

 closely j)unctured, the interstices rugosely convex, tiavous, a deeply dentate 

 and broad transverse band at the base, a narrower one at the middle and 

 another near the apex, dark blue. Length, 5 lines. 



Head opaque, dark blue, the vertex with a fulvous spot, finely granulate, 

 with a few fine punctures anteriorly ; labrum and palpi black ; antennne 

 short, the terminal joints transversely widened, black, the lower joints 

 siimiug ; thorax three times broader than long, the sides very strongly 

 wiaened. and rounded at the middle, the surface sculptured like the head, 

 with a lew minute punctures at the sides ; scutellum blackish ; elytra very 

 deeply almost foveolate-punctate, the punctures irregularly distributed, the 

 interstices everywhere varioiose or convex, a sutural and lateral narrow band, 

 as well as three transverse very ileeply dentate bands, dark blue, separated 

 by narrow similarly dentate tiavous intervals ; the anterior two bands extend 

 to either margin, but the apical one is shorter and does not touch the suture ; 

 the first band is very broad and of even width, but intersected by the narrow 

 tiavous basal margin and a narrow similarly-coloured stripe near the suture ; 

 the second band at the middle is greatly narrowed at the sutural portion and 

 follows the first baud in its indentations ; lastly, the apical band is irregular 

 in outline and does not extend to the suture ; the under side and legs are 

 metallic blue ; the mesosternum is perpendicularly defiexed, as in all the 

 species ot this genus. 



Hab. liio grande do iial, Brazils. 



I have received two specimens of this handsome species 

 from Dr. IStaudinger ; the system of coloration resembles nearly 

 C. dolabrata, iStal, but the sculpture of the thorax and of the 

 elytra is quite different.
