ORTHOMEGAS (p. 5; to follow the genus Derobrachus). 
Orthomegas, Serville, Ann. Soc. Ent. Fr. 1832, p. 149. 
A tropical American genus, of which three species only are known—one from 
South Brazil, a second from the Guiana region, and a third from the larger West-India 
islands. 
1. Orthomegas cinnamomeus. 
Cerambyx cinnamomeus, Linn. Mus. Lud. Ulr. p. 66; Syst. Nat. ed. xii. p. 623. 
Prionus corticinus, Oliv. Ent. iv. no. 66, p. 21, t. 9. f. 34, 9°. 
Hab. Nicaraceva (ex coll. Cutter)—Sovutn America, Cayenne!, Amazons. 
CALLIPOGON (p. 5). 
Callipogon barbatum (p. 5). 
To the locality given, add :—Guatemata, Cerro Zunil, El Tumbador, San Isidro, San 
Juan in Vera Paz, El Reposo, Paraiso, Coban (Champion). 
A further series of examples from intermediate localities seems to confirm the specific 
distinctness of this form from C. senex ; but the chief distinguishing feature lies less in 
the length of the mandibles of the fully developed males than in the presence of a 
longish basal tooth on the inner side of each mandible in a large male C. barbatum, and 
its absence in C. senex of the same development. The largest male in the series from 
Guatemala has the tooth, though its mandibles are nearly as long as in the largest male 
C. senex. A much larger and apparently more fully developed male from Chontales 
has very much shorter mandibles, similar, in fact, to males of the lower development in 
C. senex. 
Callipogon senex (p. 6). 
To the locality given, add :—Mexico, Santecomapan (Sallé), Misantla (Hége); Britisn 
Hownpuras, Belize, River Sarstoon (Blancaneaua). 
Callipogon lemoinei (p. 6). 
To the localities given, add :—Panama, David, Bugaba, 800-1500 feet (Champion). 
This species, Mr. Champion informs me, is attracted by light; the few examples 
obtained were captured in this manner; in the forest he did not meet with it. 
STRONGYLASPIS (p. 6). 
Strongylaspis scobinatus (p. 6). 
Thomson, in the original description of this species, makes particular mention of the 
spinose or (in one place) “subspinose” humeral angles of the elytra. As this feature 
was not repeated in M. Chevrolat’s more careful subsequent description of the same
