thus resemble A. saliei, from which they differ, however, in the elytra being entirely 
fulvous and also in the smaller size. 
Agathomerus dubiosus (p. 24). 
To the locality Mexico, add :—Cuernavaca (Sal/é). 
In the typical specimens contained in my collection the scutellum is black; in the 
example from Cuernavaca it is fulvous. A. dudiosus differs from A. rufus, to which it 
is otherwise closely allied, in the lower surface of the femora and the underside being 
black ; but it is possible that these differences may be due to variation. 
MEGALOPUS (p. 26). 
2. Megalopus violaceo-fasciatus. (Tab. XXXVI. fig. 15.) 
Elongate, testaceous, the base of the head and the breast black ; thorax with two transverse grooves, impunc- 
tate; elytra very finely and remotely punctured, each with a triangular spot at the base, a transverse one 
before the middle, and a large ovate spot near the apex, dark violaceous; legs spotted with black. 
Length 43 lines. 
Head broad, punctured near the eyes, the upper portion to the antenne black, the lower portion flavous ; 
antenn extending to the base of the elytra, pale fulvous, the lower joints entirely, and the following three 
or four joints partly, black; thorax about one half broader than long, somewhat convex, the sides slightly 
rounded at the middle, the surface with a narrow, transverse anterior, and a similar posterior groove, 
impunctate, obscure testaceous ; scutellum partly black and partly testaceous ; elytra narrowed posteriorly, 
the base slightly raised, the surface remotely and finely punctured, testaceous, a triangular-shaped basal 
spot, a transverse oblique one before the middle, and a large subtriangular spot near the apex of each, 
dark violaceous-blue ; below testaceous, a spot near the anterior cox, the breast, the four anterior 
femora above, the outer edges of the tibiee, and the tarsi, black. 
Hab. Panama, Volcan de Chiriqui (Champion). 
A single specimen. The elytra have the shoulders very prominent, their anterior 
margin in the shape of an acute oblique ridge; the two anterior spots are placed close 
together, but the posterior ones are divided by a larger space; neither of the spots 
extend to the lateral margin. 
3, Megalopus armatus.

Many specimens, which agree perfectly with Lacordaire’s description. The small 
testaceous spot visible in the type near the apex of the elytra in the male is, however, 
absent in all the examples before me. All the females have three oblique testaceous 
bands on the elytra, as described by Lacordaire; the males possess only a very narrow 
single band, placed at the middle, the rest of the surface being black. The posterior 
tibie in the male are very strongly curved, in the female much less so. In some 
specimens the elytra are entirely black in the male.
