428 TRANSACTIONS OF THE 



described by Fabricius, as a native of the island of St. Thomas, 

 and I here subjoin his definition, " C viridi-asnea, elytris albis ; 

 suturu lunulaque viridi-ceueis. Syst. Eleiit." [417] 



[Ante, 1 ; afterwards described as C.d<jnataJ)Qi. — Leg.] 



6. C. MARGINATA. — Olivaccous, obscure, sometimes with cu- 

 preous reflections; cheeks, sides of the trunk and of the abdomen, 

 with short dense hair, each elytron with a whitish margin, 

 two abbreviate branches, an intermediate refracted one, and two 

 dots at base. 



C. marginata, viridis, elytris punctis quiuque, lunulaque apicis 

 albis. Fabr. Syst. Eleut. 1, p. 241. 



Length of the male more than half an inch. 



Desc. Head greenish, olivaceous varied with purple, and 

 edged with blue ; antennae purple at base, terminal joints brown; 

 front with prostrate hair ; labrum white, with several minute, 

 obtuse teeth, in the male, with a single more prominent one, and 

 about ten marginal punctures, lateral angles rounded; cheeks 

 covered with dense hair; palpi white, terminal joint of each 

 black at the tip. Trunk, on each side cupreous, concealed by short, 

 cinereous hair ; thorax bronze or olivaceous, posterior impressed 

 line green or reddish ; elytra olivaceous-obscure, or tinged with 

 cupreous, margin pale, uniting the anterior and posterior lunules, 

 the former with an accessary spot at the middle of the base, and a 

 smaller one interrupted from its tip, the latter continued a short 

 distance upon the sutural margin, intermediate band refracted in 

 a very acute angle, at the centre of the elytron elongated, and 

 dilated behind, terminating at the suture, in a transverse line 

 drawn from the tip of the posterior lunule ; trochanters testaceous. 

 Abdomen, venter very hairy each side, segments bronzed and 

 margined with purple ; tail testaceous, of the female blackish- 

 purple. [418] 



The markings of the elytra are in many specimens so far obso- 

 lete, as to be only distinguishable in a particular light; and they 

 are always less obvious than those of the vulgaris, hirticoUis, &e., 

 to the latter of which, this insect, in the distribution of its bands 

 and lunules, bears some resemblance.
