Parnidae. 
Horn ( 1 . c . Feb. 1870, pp. 29-42) gives a Synopsis of the 
Parnidse of the United States/^ supplementing Leconte^s similar 
work. In the PsephenideSj individuals with 6 abdominal seg- 
ments and almost moniliform antennae are ? , the having an 
additional segment and subserrate antennae. 
Ilelichus foveotus, lLec.,=striatuSj id. ; gilensis and (squalis, id.,=suturalis^ 
id. : p. 33 ; lAmnius and JElmis are generically non-separable : p. 34 ; Sten- 
elmis linearis, Zimm., ?~humerosus, Mots. : Horn, 1. c. 
JElmis cenetiSj Miill. Laboulbene, Ann. Soc. Ent. Fr. (4) x. pp. 406-416, 
pi. 9, fully describes and figures with considerable detail the larva of this sp., 
of which former accounts seem to have been drawn up from dead and dried 
individuals. It appears to be closely allied to that of Potamophilus, and still 
more so to that of JMtacronychns, and to be readily distinguishable by the en- 
larged form of its thorax and the foliaceous fringes of the flattened lateral 
margins of the segments. The apex of its body is furnished with a respiratory 
apparatus, consisting of three fan-like bunches of branchice, starting each 
from a pedicle. E. ohscurus, Mull., suhparallelus, Fairm., and rimlaris, 
Rosenh., are recorded from Algeria by Fairmaire, ihid. p. 373.
