Diaphanes marginella , Ho., Luciola Gorhami, Rits. and L. ovalis, 
Ho., are the light-emitting species so abundant in trees at night during 
the rainy months. The males have a larger luminous area (three seg¬ 
ments) than the females (two segments) and are extremely bright and 
vivid in some cases. 
Telephorince .—Over fifty species are described from the continent, 
but one of which occurs in the plains. This is Tylocerus bimaculatus , 
Ho., a yellow insect with a black blotch on each elytron, the male with 
the basal and apical segments of the antenna dilated. In Silis, the 
male antennae are beautifully pectinate, the beetle flying or walking 
with the antennoe stretched out, each branch very long and erect, 
giving the appearance of a frond of a delicate plant. Insects with such 
specially developed antennae are not uncommon in deep forest and 
presumably these structures are associated with special senses. 
By some authors, the name Cantharis is associated with an insect 
of this family, which would then be known as the Cantharidce ; this 
would create profound confusion in the mind of the student, who asso¬ 
ciates the term, in all literature up to now, with the blister-beetles 
below. To such authors, the Scolytidce are Ipidce , the Bruchidce are 
Lariidce or Mylahridce , the Trogositidce are Temnochilidce or Ostomidce, 
the Parnidce are Dryopidce , the Ptinidce are Anobiidce, the Cistelidce 
are Alleculidce , and so on. It is to be hoped that such alterations in 
the nomenclature will, by the general consent of Entomologists, be 
barred ; the tendency to change names long in use on account of some 
purist’s discoveries in priority is deplorable; the work of practical and 
teaching Entomologists is being burdened with an immense nomen¬ 
clature constantly increasing in complexity, and the difficulties of the 
student are greatly increased. To convert Heliothis armigera to Chlo- 
ridce obsoleta , to call Locustidce Phasgonuridce , to change the significance 
of such names as Mytilaspis, Dactylopius , Lecanium and Coccus , (each 
with a clear significance to the practical worker) are instances of this 
practice referred to elsewhere in these pages and which the student 
should clearlv understand.
