PHOTURIS. 61 
11. Photuris mollis. (Tab. III. fig. 19, .) 
Photuris mollis, Gorh. Trans. Ent. Soc. 1880, p. 111. 
Hab. GuatEMALA, Chacoj, Zapote (Champion). 
Var. capite testaceo, prothorace fortius sparsim punctato. 
Hab. Mexico, Tuxtla (Sallé). 
The specimen figured is a male from Zapote. 
Smaller than P. fruticola, and with the disk of the thorax infuscate; the scutellum 
also fuscous. 
The specimens in Sallé’s collection are like P. frontalis in the yellow head and punc- 
tuation, but smaller in size, and with the disk of the thorax infuscate. 
12. Photuris lugubris. 
Elongata, aterrima, subopaca, prothorace flavo nitido. Long. 11-14 millim. ¢ @. 
Mas segmentis ventralibus tribus ultimis flavis, quinto et sexto longis eburatis. 
Femina segmentis tribus ultimis flavis. 
Var. a femoribus testaceis, coxis anterioribus et intermediis pallidis. 
Var. B capite, scutello et mesosterno flavis, pedibus brunneis basi testaceis. 
Hab. Mexico, Oaxaca, Juquila (Sallé).—Var. a. GuatemaLa, Purula (Champion).— 
Var. 6. Mexico (Sallé, coll. Sturm). 
The coloration of this species is common to several Coleoptera from the same region, 
and is so precisely repeated in a species of Telephoride that they are usually confounded. 
It is also almost exactly that of P. funestis, Gorham, a species occurring in Colombia 
and Ecuador; from the latter the three luminous segments at once distinguish it, 
P. funestis belonging to a section in which one segment (the fifth) in the female and 
two in the male are white. I should have been inclined to give specific value to the 
variety B, but that the variety « is as nearly as possible intermediate, and would in 
that case have also to be separated. In the male the fifth and sixth segments are 
angularly emarginate, but not always conspicuously so; the apical segment is cut out 
on each side, so as to form a lanceolate lobe in the middle; but this is not often very 
distinct, so that the best distinction is the large eyes and the lengthened, and smooth, 
shining yellow fifth and sixth plates. 
A further point of distinction between this and my P. funestis is that the thorax here 
is more elongate, narrowing to the front, while in the latter it is almost semicircular. 
13. Photuris simplex. 
Flava; antennis, palpis, ore, tibiis tarsisque infuscatis, prothorace nitido vix punctato. Long. 13 millim. 9. 
Hab. Costa Rica, Volcan de Ivazu, Rio Sucio (Rogers). 
The plain ochraceous-yellow colour of this species sufficiently distinguishes it, the only
