Taken in abundance by Mr. Champion in one spot, but he found it to be very local, by 
the side of a little stream in the forest at 4500 feet altitude. It emits a pale green 
bright light, and is rather rapid on the wing. 
LUCIDOTA (p. 34). 
12. Lucidota incompta. (Tab. XI. fig. 22.) 
Elongata, nigra, supra ochracea; prothoracis disco nigro-piceo utrinque miniato, scutello nigro-piceo. Long. 
14-16 millim. ¢ 9°. 
Mas. Antennis longius flabellato-pectinatis, segmentis duobus ultimis pallide flavis. 
Femina, Antennis acute serratis, segmento apicali flavo.

In form, and in the pectination of the antennae, this species is not like any we have 
before recorded ; it belongs to a section of the genus common in Brazil and other 
parts of South America, of which L. flabellicornis, F., is the type. It differs from any 
of that section known to me in its ochraceous or brown colour above. The head is 
black and shining, the whole of the body is black with the exception of the tips of the 
coxee and bases of the trochanters, the point of insertion of the antenne, the mandibles, 
the front margin of the metasternum, and apical segments mentioned, which are all 
yellowish. ‘The thorax is yellow, roughly punctured, the centre of the disc pitchy black, 
smooth and shining, with a distinct vermilion patch on each side; the basal part of the 
black portion is extended transversely a little along but not touching the base. The 
centre of the disc is obsoletely impressed, scarcely channelled. ‘The scutellum is pitchy 
black and shining. The elytra are generally unicolorous, rarely very faintly infuscate. 
A good series of these species was secured by Mr. Champion at a high elevation. Most 
of these specimens were captured either on the wing in the daytime in dark places in 
the forest, or by beating herbage along the forest margins. 
13. Lucidota fuscata. 
Oblonga, minus elongata, nigro-fusca, supra sordide testacea; prothorace lateribus pallide flavis, disco indeter- 
minate infuscato, obsolete canaliculato, utrinque miniato. Scutello elytrisque infuscatis, his marginibus 
dilutioribus, obsolete costatis. Long. 11-12 millim. ¢ @. 
Mas. Antennis compressis vix serratis; segmentis quinto et sexto rosaceis; apicalibus vel flavis vel medio 
infuscatis. 
Femina. Antennis brevioribus. 
Hab. Panama, Bugaba (Champion). 
This is one of the species which, by its obscure colours and general appearance, so 
simulates a variety of other species as to render its discrimination a perplexing matter 
unless its generic characters are grasped. ‘Thus it has a general and very close likeness
