15. Photinus salvini. (Tab. IV. fig. 6.) 
Ater, opacus, subtus subnitidus, prothorace sanguineo, medio late nigro-vittato, elytris obsoletius costatis. 
Long. 15 millim. ¢ 9. 
Hab. Mexico, Durasnal, Parada (Sallé). 
This is perhaps the most beautiful of the Lampyride, the blood-red colour of the 
thorax contrasting with the opaque black elytra. It is allied to P. stwrmiz, but is more 
oblong than that species; the thorax is formed much as in the genus Phenolis, 
prominent in front, much rounded at the sides, and contracting to the hind angles, 
which are acute. The front and lateral margins incline to yellow, especially under- 
neath. The disk has a clearly defined black vitta from the base, where it is widest, to 
to the front; it is hardly carinate in front, and very obsoletely channelled in the 
middle. The antenne are compressed, widest in the middle, their second joint distinct, 
only half as long as the third. In neither sex is there the slightest trace of luminous 
spots. The male has the eighth or genital plate distinct, the seventh nearly as long 
as the sixth, and only little emarginate. The female has the apical plate notched, but 
neither of the preceding ones. 
There are two specimens of this in the British Museum; and these, with the male 
and female in M. Sallé’s collection, are all I have seen. 
The figure represents the female from Durasnal. 
16. Photinus guatemale. (Tab. III. fig. 10.) 
Photinus guatemale, Gorh. Trans. Ent. Soc. 1880, p. 26. 
Hab. GuateMALA, Calderas, Duefias (Champion). 
17. Photinus lunicollis. (Tab. III. fig. 9.) 
Photinus lunicollis, Gorh. loc. cit. p. 27°. 
Hab. Mexico, Puebla, Yolos (Sadlé); Guatnmata, Capetillo, Duefias (Champion). 
About twelve specimens of this pretty species have been received from Capetillo. I 
have only seen one from Duefas. The figure is that of a female from Capetillo. 
18. Photinus ruficollis. 
Photinus ruficollis, Gorh. loc. cit. p. 27°. 
Hab. Mexico, Cuernavaca (Sturm, coll. Sallé); GuateMaLa, Zapote (Champion) !. 
Similar in coloration to Lucidota bella, Photuris collaris, and other species; it may, 
however, be known by its /eaden-black depressed elytra, as well as by the almost totally 
pale abdomen. 
The specimens in M. Sallé’s collection, three in number, from Mexico, are much 
larger than the type, and are named awranticollis, Sturm. They are two males and a 
female, 14-16 millimetres in length; the former have the base of the fourth, the fifth,
