probably U. orozimbo, Fairm., which he found some years 
ago in the western district. They have a thorn-like process 
on the pronotum, and were in numbers on the stem of a small 
shrub, which Dr. Davis thinks was unprovided with spines, 
but these insects, ranged down the stem, gave the appearance 
of a very prickly plant, and one dangerous to handle. They 
remained perfectly motionless, thus adding to the deception. 
There are two beetles which Mr. Champion has kindly 
identified for me. One of them, a Longicorn, Crioprosopus 
thoracicus, White, a very handsome insect, recorded in the 
“ Biologia’ from Honduras only, comes with the moths 
from Castile, and is the only specimen Dr. Davis has met 
with. The other, a Buprestid, EHuchroma goliath, Lap. and 
Gory, appears to be a commoner beetle of wider range. 
Appended is a list of the Syntomidae and Arctiadae collected 
by Dr. Davis at Castile, British Honduras, in June, 1912 :— 
SYNTOMIDAE.—Pheva albisigna, Walk., Loxophlebia masa, 
Druce, L. invtata, Druce, L. davisi, n. sp., Rhynchopyga 
flavicollis, Druce, Chrysostola (Dycladia) augusta, Druce, 
Macrocneme auripes, Walk., M. mgritarsia, Hampson, M. 
% jalapensis, Sch., Dinia aeagrus, Cram., Mesolasia haemor- 
rhoidalis, Stoll, Trichura druryt, Hb., Argyroeides minuta, 
Druce, Epanycles imperialis, Walk., Napata leucotelus, Butl., 
Aclytia punctata, Butl., and ab. 1, Hampson, Heliura rhodo- 
phila, Walk., Amycles anthracina, Walk., Eryphioides tracti- 
pennis, Butl. 
ARCTIADAE.—Belemia jovis, Butl., Agyrta dux, Walk. 
(Isostola superba, Druce). 
THe ForMs PICEA AND GAGATES OF Formica Fusca.—Mr. 
DonisTHoRPE exhibited ¢¢ and S38 of Formica fusca, var. 
picea, Nyl., from the New Forest, and a ? from Belgium, and 
pointed out that it was standing in the British lists as gagates, 
Latr. He gave a history of var. picea as British, and ex- 
hibited 8% and a ? of the true F. fusca, sub-sp. gagates, Latr., 
from Vienna, and illustrated the structural differences between 
the two forms on the blackboard. He pointed out that 
gagates has not occurred in Britain.
