Elytra yellow, with ferruginous clouds and black spots, strongly convex ; very delicately 

 punctate-striate, the punctures only distinct in the central part, and the sutural row 

 almost entire, but with this exception they are smooth; the black spots are— one 

 near the base (like a Hebrew character, with a small projection joining it to the base), 

 one median (like three oblong spots united), one subapical (heart-shaped), and one 

 in the middle of the suture, common to both elytra, oblong. Legs testaceous-red, the 

 extreme tips of the thighs and the tarsi dark pitchy-red, the tibiae almost black. 

 Underside testaceous. Two examples.

The synonymy quoted above will show that this is a very extensive genus whose 

 limits it is difficult to define. In treating of a local fauna it would be undesirable to 

 revive any of the above names. Lacordaire only notices them as subgenera. We 

 quote them as they have been so generally used in collections. Brachysphenus contains 

 about one hundred and eighty described species, but many more exist in collections. 

 They are all American, and are confined to the tropics. The species are generally of 

 moderate size, and very varied in colour and pattern.

The specimens which Mr. Champion collected of this beautiful species are con- 

 siderably larger than the two from Panama in Crotch's collection, being a little over 

 eight (instead of from six to seven) millimetres in length. It is distinguished from the 

 species which follows, and with which it might easily be confused, by the more oblong 

 form, by the different denticulations of the yellow fasciae (which a reference to the
