MALACODERMATA. 249 
1. Lycinella opaca. (Tab. XI. fig. 15.) 
Nigra, opaca ; prothoracis margine laterali et frontali late elevato, sanguineo ; elytris costis duabus una humerali 
una discoidali elevatis ad apicem fere provectis, intervallis subrugosis. Long. 4-5 millim. 
Hab. Guatemata, San Juan in Vera Paz, Tamahu (Champion) ; Panama, Volcan de 
Chiriqui (Champion). 
This little species has at first sight apparently ten-jointed antenne, but a very small 
second joint really exists. It presents many points of resemblance to the species of the 
genus Taphes, which inhabits the Eastern Tropics, especially in the structure and 
pubescence of its antenne; but the thorax is quite differently formed. In addition to 
the two raised coste mentioned in the diagnosis, this species has the alternate interstice 
next the suture a little raised, especially at the base. 
Only four specimens have yet been seen by me, the one figured being from 
San Juan. | 
2. Lycinella parvula. (Tab. XI. fig. 16.) 
Nigra, opaca; prothoracis margine laterali sat late, frontali tenuissime rufo, disco antice carinato, carina postice 
minute diviso; elytris paullulum ampliatis, opacis, costis humerali et discoidali nisi ad basin vix elevatis. 
Long. 4-44 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
I at first thought a separate genus should be made for this insect, as it differs from 
the preceding species in many minute details. The carina is divided behind, making a 
very small open cell, but this is not always visible. The antenne are shorter, and quite 
simple. The elytra appear to be softer and expand more behind, but I now hesitate to 
give these differences more than specific rank. One specimen occurred in the hot low 
country at Bugaba, and is the one selected for the figure. The others were found 
at a higher elevation on the Volcan de Chiriqui. 
LAMPROCERA (p. 29). 
Lamprocera picta (p. 30). 
Var. Elytris basi usque ad medium flavescentibus, interdum macula magna subhumerali nigra. (Tab. XI. 
fig. 17.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Two specimens, one with a lateral spot near the base of the elytra, the other with 
the basal half entirely brownish yellow, were met with. The latter so closely resembles 
the species I have identified as L. castelnaui, Kirsch [cf. Trans. Ent. Soc. 1880, p. 4], 
that I think possibly that species is the southern form of LZ. picta. My specimens, 
which I suppose to be ZL. castelnaui, are from Colombia, and are larger and exhibit 
some minor differences of colour and pattern. Mr. Champion informs me that these 
insects are sometimes found on the wing in the forests in the daytime.
