Genus 3.— Pyragropsis, Bor. 
This is a monotypic genus founded by Borelli for F. 
tristani, from Costa Rica. It is a handsome species, of a 
strikingly contrasted black and yellow coloration. 
Genus 4.— Echinopsalis, Borm. 
This genus still contains only E. guttata, Bonn., as 
E. hrevihractea, Rehn, I consider to be a larva of Pyrogra 
fuscata (q. v., ante, p. 166). 
I have in my collection a single female from Peru, 
which may be referable to this genus; the head is de¬ 
pressed and brick-red in colour, the pronotum, tawuy, with 
black band, as also the elytra and wings; the tarsi are 
Possibly Fsalis thoracica, Serv., is referable here ; it is 
certainly a Pyragrid. The specimen figured by de Borman 
(1893, p. 4, PI. I, fig. 7) is a female ; it is very small, being 
only 6.5 mm. long. 
Sub-family Q.—FSALINAE. 
This sub-family includes those genera in which the 
metasternum is truncate posteriorly, but the mesosternum 
rounded, except in the monotypic genus Titanolahia, in 
which the metasternum is produced into a lobe, rounded 
at the extremity. All the genera include rather stoutly 
built species; the forceps are strong and trigonal, never 
very long, nor slender, often subcontiguous in the male,
