258 SUPPLEMENT. 
collected by Mr.Champion; they were probably not distinguished at the time from L. com- 
planata. The seventh ventral and the pygidial plates afford an opening, within which 
the genitalia lie concealed; but in this and its allies I think I recognize two curved 
style-shaped or filiform processes, which may act as claspers. ‘These parts are all very 
soft, and sufficient specimens are not available at present for ascertaining by dissection 
whether they will prove of any use in the formation of a genus. 
23. Lucidota comitata. 
Nigro-fumosa, subparallela ; prothorace albido, disco nigro-vittato, utrinque miniato; elytrorum limbo laterali 
pallido; antennis nigris leviter serratis. Long. 64-7 millim. ¢. 
Mas. Segmento ventrali septimo utrinque macula parva haud distincta albescente. 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
This is one of the smallest Lucidote, and as it precisely resembles in colour and size 
Photinus plumbeus and P. concinnus, it would be readily confused with them, unless 
the more compressed, broader, and more serrate antenne were noticed. On examining 
the underside a greater difference would be seen, as, instead of the abdomen being 
wholly white in its apical half, only two very inconspicuous spots are to be seen on 
the penultimate ventral plate. 
It appears to be not uncommon in the localities where it was found. 
Lucidota diaphanura (p. 36). 
To the Mexican localities given, add :—Misantla (Hoge, 3 ), Chiquishuita (coll. Sallé). 
The two males noticed in my description as differing slightly from the type are from 
the locality last named. Three males in Hoge’s collection are most intensely black in 
the dark parts, and have the margins of the thorax narrowly black. 
Lucidota discolor (p. 37). (Tab. XI. fig. 23, var.) 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
PHOTINUS (p. 38). 
1 (a). Photinus incongruus. 
Oblongus; elytris sat latis, fuscis, margine toto vittaque ante apicem abbreviata testaceis ; prothorace pallide 
testaceo disco nigro-fusco utrinque miniato ; scutello fusco, apice dilutiore; corpore subtus nigro (seg- 
mentis diaphanis exceptis) ; femoribus basi coxisque pallidis. Long. 16-18 millim. ¢ 9. 
Mas. Segmentis quinto et sexto ventralibus totis lete flavis, eburneis, septimo perbrevi pallido, genitali parvo, 
egre observando pallido, pygidio nigro. 
Femina. Segmento quinto in medio transversim diaphano; sexto, macula mediana pallida, margine apicali in 
medio minute exciso; apicali fusco apice exciso. 
Hab. Guatemata, Chinantla (coll. Sallé ¢ 2); Panama, Volcan de Chiriqui (Cham- 
pin). .
