472 Mr. CuRTis's Descriptions of 



Moderately tapering : black, thickly and minutely punctured, and densely clothed with 

 short depressed blackish pubescence ; 7 apical joints of antennae a little dilated, obtri- 

 gonate : head globose : thorax broader, but long, the base somewhat lobed and mar- 

 gined with whitish silvery hairs ; scutel, a narrow space round it, and 2 spots on each 

 elytron of the same, one being oblique and before the middle, the other beyond it : the 

 elytra are more than twice as long as the thorax and expose only the apex of the stout 

 aculeus, the base of which, as well as 2 spots on each segment, are silvery : underside 

 and legs sericeous ash-colour, forming yellowish silvery spots in certain lights. 



This pretty species was found at Conception. 



Family CANTHARiDiE.

Nigra pube cinerea, puiictis nigris minutis sparsiin conspersa.

 Length 5 lines, breadth 2. 



This pretty species was apparently abundant at Gorrite, but I am unable to 

 ascertain whether it be Germar's and Klug's species, not knowing where it is 

 described. Dejean has included it in his genus Epicauta, which is distin- 

 guished from Lytta by its setaceous antennae.

Tetr. 4-maculatus, Fabr. Ent, Syst. i. part 2. p. 50? 



As Fabricius says the thighs are rufous, which is not entirely the case in 

 our insect, a good portion of the apex being black, I am led to doubt whether 

 the above be synonymous species, especially as our specimens come from Rio 

 Janeiro, and the Fabrician inhabits North America. 



*139. Tetraonyx 7-guttatus, Curt. 



Niger, suprk aurantiacus, capitis thoracisque macula elytrorum maculis 4 ba- 



salibus fasciaque postmediana irregulari nigris, femoribus basi rufis. 

 Length 5| lines, breadth 2\. 



Black, shining ; head and thorax punctured, hairy and rufous, the former with the clypeus, 

 margins of the eyes and a diamond spot on the face extending by a line to the base, 

 black ; the latter transverse, with a similar spot on the disc : scutel large and black.
