20 AMERICAN ENTOMOLOGY. 



pressed puncture at base above : thorax sanguineous, with five 

 black spots, of wbicb two are on each side, the posterior one 

 larger, oblique, and generally confluent along the basal margin 

 with the opposite basal spot, the central spot is dilated and elon- 

 gated, fusiform : scutel black : elytra black, with punctured striae ; 

 interstitial lines flat, punctured, penultimate lateral one and ulti- 

 mate one at base sanguineous : thighs with a dull sanguineous 

 spot on the middle, obsolete on the posterior pair. 



Size of the preceding. 



I observed this species to be very abundant on the Southern 

 Sea Islands of (jeorgia ; many specimens also occurred in East 

 Florida, but I cannot learn that it has ever been taken further 

 north than that State, neither does it seem to inhabit the western 

 region. 



The upper right figure ; the natural size is exhibited by a line, 

 above which is an enlarged representation of the head. 



Calandra compressirostra. — Specific character. Castane- 

 ous black ; rostrum compressed ; a profound frontal puncture : 

 thorax with two punctured lines converging to the scutel. 



Calandra compressirostra nobis, Journ. Acad. Nat. Sciences, 

 vol. iii. p. 319. 



Desc. Body dark chestnut-brown, passing into blackish : head 

 with small distant punctures, larger ones on the base of the 

 rostrum, which decrease in size to the tip ; a profoundly impressed 

 large puncture between the eyes : rostrum very much compressed, 

 acutely carinate above : antennae at the tip rufous : thorax with 

 larger punctures on the side, on the anterior impressed submargin 

 and on two indented lines which originate each side of the 

 middle and converge to the suture : elytra with crenate striae ; 

 interstitial lines each with a series of punctures: tibia with a 

 very robust obtuse spine and setae below the anterior middle. 



Obs. This singular species occurred near the Rocky Mountains, 

 on the banks of the Arkansaw river. It is widely distinct from 

 either of the preceding species, as well by the much compressed 

 form of the rostrum, as by the more obvious dissimilarity of 

 color. 



The upper left figure ; the natural size is represented by a line, 

 and an enlarged view of the head and part of the thorax is 

 added.
