fourth joint of the rostrum. Narnia is both Neotropical and Nearctic, one species being 
found in Central America, and another in Texas. This isthe present extent of the genus.

In his description Stal does not mention the presence of a white spot on the inner 
dilatation of the posterior tibisee, which is present in a Mexican specimen forwarded to 
me by Dr. Signoret, and also in two specimens from Guatemala, one of which is here 
figured.

This second division of the Coreine is distinguished from the preceding in having the 
posterior tibie simple. The femora are spined beneath. Four genera are comprised in 
this division, all of which are Neotropical. Three of these are found in Central America, 
one of which extends into the Nearctic Region, the fourth, according to our present 
knowledge, being confined to the Amazonian and Colombian subregions.

In this genus the abdominal spiracles are considerably wider apart at the base than 
at the apex of the abdomen. The apical angle of the corium is somewhat elongated 
and produced, but not beyond the basal half of the membrane. About a dozen species 
are known as belonging to this truly Neotropical genus, of which one only has been 
received from Central America : — 
1. Leptoscelis tricolor. (Tab. XIII. fig. 5.)

PHTHIA. 
Phthia, Stal, Stett. ent. Zeit. xxiii. p. 294 (1862) ; Ofv. Vet.-Ak. Férh. 1867, p. 545. 
Phthia differs principally from the preceding genus in having the abdominal spiracles 
only slightly wider apart at the base than at the apex of the abdomen. This is a
