these forms. Prof. Riley has proved that to demonstration, if proof were 

 required to the statements of eadier writers. 



Genus Eupseudosoma Grt. 



1865 — Grt, Proc. Ent. Soc, Phil., 240. 



This genus I do not know autoptically. Mr. Grote, describing a 

 male, gives the character, from which the following notes are made : 

 Body stout; finely scaled, squammation close and short ; head prominent, 

 eyes large ; tongue moderate, palpi finely scaled, not exceeding the front ; 

 legs rather stout, finely scaled, provided with minute spurs ; antennae 

 long, biserrate, tapering to the tips, the serrations short, acute and rather 

 distant ; primaries large, triangulate, apices produced, costa very straight, 

 external margin oblique ; discal cell open ; veins 3, 4 and 5 very nearly 

 from one point, 2 not greatly removed from 3. 



Unfortunately, Mr, Grote does not describe the arrangement of the 

 costal series, but it is probably not different from Spilosotna. The vena- 

 tion of the secondaries is not described. Our only described species is : 

 E. floridum Grt. 



1882 — Grt, Can. Ent., XIV,, 187, Eupseudosoma. 

 Habitat — Flo rida. 

 Said to be closely allied to the Cuban E. niveum.

Pygarctia Grt. 



1871 — Grt, Can. Ent., HI., 124. 

 Head moderate or rather large, closely applied to the thorax; eyes 

 large, but not prominent. Palpi slender, not exceeding the middle of the 

 front; third joint moderate. Tongue long, corneous. Antennae long, in 

 the ^ rather lengthily bipectinated. Legs with rather close vestiture, 

 posterior but little the longer, spurs normal. Vestiture hairy, but rather 

 close. Abdomen exceeding secondaries, cylindric, obtusely terminated. 

 Primaries with 10 out of the subcostal before the end, 7 to 9 on the
