zontal effects of distribution. I am studying the genus Lyccena and 
think many names will eventually have the same value as those under 
pseudargiolus , of which we now have nine names. They represent what 
many of the others will in the future—gradational geographical forms 
and seasonal variations. When people put date and locality on the 
pins we will be able to find out these things. I have expressed my 
views in regard to Pamphila. See Can. Ent., Vol. XXVII, p. 261. The 
variations of comma should not be entitled to specific value. The spe¬ 
cies in Nisoniades are in bad shape and need careful study. I believe 
we have some synonyms among them. The species of Aegiale are in¬ 
teresting, and may be modifications produced by season, condition of 
food plant, etc. Neumoegeni is a very distinct species. The others 
are more nearly related.

DESCRIPTION OF THE LARVAE OF SOME HETERO- 
MEROUS AND RHYNCHOPHORUS BEETLES. 
(Plate IV, figs. 1-6 ) 
By H. F. Wickham. 
The following descriptions have been written for the sake of mak¬ 
ing known to American students the immature stages of some of our 
beetles. In view of how little has been done in this country, it will not 
surprise most Coleopterists to hear that they all belong to genera in 
which none of the species peculiar to our continent have yet been 
studied in the larval state. 
Nearly all of the details are from camera-lucida drawings of balsam 
mounts ; they are, however, not all on the same scale, being made from 
time to time as leisure offered and with different instruments. 
Megeleates sequoiarum Casey. (Fig. 1.) 
Larva cylindrical, elongate, tapering slightly to each end. Color 
in spirits yellowish:, head somewhat darker, mouth parts castaneous. 
Length 16 mm. Head barely perceptibly narrower than the prothorax, 
sides rounded, front nearly vertical, flattened. A distinct ridge runs 
down on each side of the frontal declivity to the base of the mandibles. 
The ocelli are situated on the upper or posterior portion of this ridge 
and are connected with each other by a transverse, very tortuous raised 
line. Antennae situated exterior to the mandibles, apparently four-
