LATERNARIA.—PHRICTUS. 28 
Laternaria is a truly Neotropical genus; and it was to one of its species that the 
attribute of luminosity was first applied. The evidence for and against the luminosity 
of the Fulgorine has been so thoroughly stated, and the negative evidence in the 
writer’s view so thoroughly established, that little need be added, save that Dr. Hagen 
(Ent. Mon. Mag. i. p. 250) has proposed the alternative hypothesis that the species are 
“only luminous at certain seasons, or, which is very credible, the luminosity may be 
confined to one sex.”

Lhave no hesitation in identifying these Panama specimens as belonging to Spinola’s 
species, owing to their agreement with Burmeister’s description of that species in 
several most important and essential particulars. Thus, of the head “supra utrinque 
nigro-maculato,” and “colore viridiore,” and “ventre sanguineo” are characteristic 
descriptions which prove most applicable to the specimens now before me, one of 
which is here figured. 
PHRICTUS. 
Phrictus, Spinola, Ann. Soc. Ent. Fr. viii. p. 216 (1839); Stal, Hem. Afr. iv. p. 1382 (1866) ; 
Stett. ent. Zeit. xxxi. p. 284 (1870). 
In this genus the head is very much produced, the prolongation ‘being porrect and 
dentate, the apex recurved and angularly or dentately lobate. 
Phrictus, according to our present knowledge, is a genus very small in extent, and 
quite confined to Tropical America, where apparently it is not found south of the 
Brazilian subregion, nor so far north as Mexico. 
Two species have at present been received from Central America.
