 NOTES ON A FEW OF THE ABOVE COLEOPTERA. 



It is extremely difficult, among many interesting groups, to 

 select a few for special notice; but I may mention the fireflies 

 (Lampyridce and Telephoridce), and the genus Lytta (Cantha- 

 rida}, which are used medicinally. " The genus Cyphus, 

 peculiar to South America, is one of the finest of the family ; some 

 of the species, e.g. Hancocki, are the largest and most magnificent 

 of known Curculionidse." * 



" Four splendid species constitute the genus Entimus ; they are 

 imperialis^ Fors., splendidus, Fabr., nobilis, Oliv., from Brazil, and 

 granulatus, Linn., from Cayenne. They have been known for a 

 long time, and are more or less common in collections. With the 

 exception of splendidus, which is adorned by patches partly 

 confluent, of a brilliant coppery green, all are uniformly covered 

 with scales of a beautiful golden green. They are peculiar to 

 South America, and are generally found together in more or less 

 numerous bands. I have several times seen, in Brazil, mimosas 

 loaded with specimens of imperialis, so that their branches bent 

 under the weight" f 



The beautiful little metallic blue beetle, Compsocerus jucundus, 

 Dej., is worth mentioning, as it has curious black hairy tufts in the 

 middle of its delicate long antennae. Mr. Bates \ refers to another 

 Longicorn, Coremia hirtipes, which has a tuft of hair on its hind 

 legs, and remarks, " It suggests curious reflections when we see 

 an ornament like the feather of a grenadier's cap situated on one
