20 Rev. H. S. Gorliam's materials for a 



being not so long as in Jlahellicornis, and equal to eacli 

 other, excepting that on the 10th joint, which is shorter. 

 Thorax, with the expanded lateral niargins, yellow : the 

 disc is pitchy-black from the base to near the apex, but 

 leaving the anterior margin yellow; hind angles acute. 

 Scutelhim black. Elytra black round the scutellum, as 

 far as the humerus, and the apical portion (rather less than 

 half) yellow in the central half, and lateral margin at the 

 base, dull. Abdomen, with the dorsal segments, acute 

 at the side, the sixth sublobate, the pygidial having the 

 apex truncate, emarginate sinuosely, the sixth ventral with 

 a luminous spot on each side, the seventh small, lobiform, 

 compressed at the apex. 



Brazil, Brus. M. ; a single specimen. 



Lucidota ajncicornis, n. sp. 



Fusco-nigra, thoracis limbo, elytrorum marglne laterali, 

 pedibus basi, et antennarum articulis tribus apicalibus 

 albis, thoracis disco nitido miniato in medioj et ad basin 

 infuscato. 



Long. lin. 5. 



The antennre are about the length of the body, the 

 intermediate joints triangular, longer than wide, com- 

 pressed, serrate ; the 9th white, but infuscate at its base, 

 the 10th and lltli entirely white. The thorax equal in 

 length and width at the base, Avhite, with the disc and 

 prosternal parts of a beautiful carmine, more or less infus- 

 cate in the centre. Abdomen white or yellowish at the 

 apex.

 p. 580. Columbia, Brus. M. ; Nicaragua, Chontales; 

 coll. Godman and Salvin. 



Obs. — The Nicaragua specimens differ from the type 

 in being smaller, in having the antennge less acutely 

 serrate and the upper surface duller: but as the type is 

 at present unique, it will be better not to separate them at 

 present. 



A second specimen in Guerin's Coll., Brus. M., is, I 

 think, to be doubtfully referred to this species ; it is from 

 Caraccas. 



Lucidota limhata, n. sp. 



Sordide nigro-picea, thorace elongato pilcato, rufo-flavo.
