ETHRA (p. 32). 
Akthra despecta (p. 32). 
To the localities given, add:—Panama, Bugaba, Volcan de Chiriqui (Champion). 
All the specimens taken at Bugaba, and on the Volcan de Chiriqui, agree in having 
subpectinate antenne, and as far as I can see in the structure of the abdomen. 
Specimens from Colombia in my own collection, which have the antenne serrate and 
the disc of the thorax infuscate, are doubtfully a distinct species; one example quite 
agrees with the Chiriqui species. There remain but two specimens with simply serrate 
antennee, viz. those from Cache, Costa Rica, and I now incline to think these are not 
properly assigned to the present species. Hence the female is not certainly known. 
3. Aithra brunnipennis. (Tab. XI. fig. 19.) 
Aithra brunnipennis, Gorh. Trans. Ent. Soc. 1880, p. 13°. 
“Nigra, subnitida ; elytris brunneo-flavis, thorace canaliculato, semicirculari.” Long. 10-11 millim. ¢? 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
Head and thorax black, the former slightly impressed between the eyes, mandibles 
pitchy ; antenne nearly as long as the body, with their third to tenth joints acutely 
produced, so that the produced part is about equal to the joint in length. Thorax 
thickly punctured, margin reflexed and somewhat thickened, central channel ill-defined. 
Scutellum more shining than the thorax, its apex truncate. Elytra rusty yellow, almost 
exactly as in A. despecta. Legs black. 
A series of specimens only varying a little in size were taken. I have a species rather 
closely allied to this, but with nearly simple antenne, from Ecuador. This species was 
found on the wing in the daytime in the dense forest, and sometimes to be seen sitting 
on the leaves. 
DRILOLAMPADIUS (p. 33). 
Drilolampadius stolatus (p. 33). 
To the localities given, add :—Mextico, Jalapa (Hoge); Panama, Bugaba, Volcan de 
Chiriqui (Champion). 
Var. GuaTEMALA, Las Mercedes, San Isidro (Champion). 
Mr. Champion met with large numbers of both this and the following species in the 
State of Panama, from an examination of which I am able to supply the sexual differences 
and further details. In D. stolatus the antenne of the male have the filaments not more 
than twice the length of the joints; those of the female are very much shorter, with 
rudimentary filaments. In D. scutellaris the males have very long filaments three to 
four times the length of a joint; the terminal joint is generally yellow. The colour is
