Mr. Charles J. Gahan on the 
AcANTHODERES, Serville. 
179. AcantJioderes circumflexa, Duval, Sagra^s Hist. 
Cuba, Ins., p. 270 (1857). 
Hob. Cuba ; also Central America, from Mexico to 
Colombia. 
This species seems to me to be scarcely distinct from 
tbe North American A. quadrigibhaj Say, Boston Journ. 
i., p. 195 (1835). 
Lagochieus, Erichson. 
180. Lagochirus araneiformisj Linn. 
Cerambyx araneiformis, Linn., Syst. Nat., Ed. xii., 
p. 625 (1766) ; Drury, lUust. ii., p. 66, pi. 35, fig. 4. 
Hab. Grenada and St. Yincent (H. H. Smith), 
Guadeloupe, Antigua, St. Thomas, St. Bartholomew, 
Haiti, Cuba, Jamaica; and commonly distributed through- 
out Tropical America. 
This well-known species has been recorded also from 
the Sandwich Islands. 
181. Lagochirus obsoletusj Thoms., Essai Class, des 
Ceramb., p. 10 (1860). 
Lagochirus longipenmSj Bates, Biologia C. A. Col. v., 
p. 145. 
Hab. Cuba(Poey); Nicaragua, Honduras, Guatemala, 
and MexicOi 
A single example from Cuba, of Chevrolat^s collection, 
is referable to this species. There are examples also in 
the British Museum collection which have come from the 
Sandwich and Loo Choo Islands. 
The differences which Bates mentions as distinguishing 
longipennis from obsoletus must have sprung from the 
author's own imagination. At least, I must confess that, 
with examples named by Bates before me, I am quite 
unable to appreciate the distinction he has drawn 
between them. 
182. Lagochirus tuberculatus, Fabr. 
Cerambyx tuberculatus j Fabr., Mant. Ins. i., p. 131 
(1787) ; Oliv., Ent. iv.. No. 67, p. 109, pi. 16, fig. 114. 
Lamia tuberculata, Fabr., Ent. Syst. i., 2, p. 273.
