58 MALACODERMATA. 
5. Photuris collaris. (Tab. III. fig. 15.) 
Photuris collaris, Gorh. Trans. Ent. Soc. 1880, p. 107. 3 a: 
Hab. Muxico, Cuernavaca (Sallé); Guatemata, Zapote (Champion). 
The figure is that of a Zapote specimen, a rather small female. 
The thorax is wholly orange-red and shining; the genital segment of the abdomen 
and the produced lamella of the plate preceding are black, the fifth and sixth segments 
wholly yellow and eburate. Very few specimens have been sent. 
6. Photuris lucidicollis. (Tab. III. fig. 14.) 
Photuris lucidicollis, Gorh. loc. cit. p. 107. 
Hab. Guatemaua, Duefias, San Gerdénimo, Capetillo (Champion).—Var. MeExico, 
Cordova, ,Panistlahuca, Cuernavaca (Sal/é); GUATEMALA, Panima, San Gerdnimo, 
Capetillo, Duefias (Champion); Costa Rica. 
The specimen figured is from Duefias. 
A variable species, both as regards size and coloration, the latter being either quite 
dark fuscous, with paler margins to the elytra, or pale with a central obscure pale vitta ; 
this form has only occurred as yet at Duefias. The luminous portion of the abdomen, 
however, seems constant, the apical excised segment in the female being usually infus- 
cate, but sometimes quite yellow. The pale specimens resemble Lucidota apicicornis, 
and the darker ones Photinus cinctellus; but the generic characters, especially the 
form of the thorax, the structure of the abdomen in the male, and of the claws, will 
always suffice to prevent their being confounded. 
Section II. 8. Male with external claw split; female with the claws simple. 
7. Photuris amena. 
Photuris amena, Gorh. loc. cit. p. 108’. 
Hab. Mexico, Vera Cruz, Tepansacualco, Cordova (Sallé); GuatTEMALA, near the 
city, San Gerénimo! (Champion); Nicaragua (Sallé). 
A species with a very Photinoid aspect, and placed in that genus in M. Sallé’s and, 
no doubt, in most collections; the external claw, however, is split in the male; and 
although in the female the head is not more exserted than in many Photini, in the 
male it is incapable of being withdrawn and is visible from above. The elytra are 
almost parallel, and the thorax of nearly the same width, with acute hind angles, the 
head black, the antenne dark to the base. The body beneath is pale, excepting the 
basal segments of the abdomen. ‘The series of specimens in Sallé’s collection are paler 
than those from Guatemala. 
Apparently a very common species and widely distributed.
