Cyllene erythropus (p. 47). . 
To the localities given, add :— Mexico, Alamos (Buchan- Hepburn), Ventanas (Forrer), 
Guanajuato (Sallé), Almolonga (Hége). 
The single example from Alamos is very large and fine (11 lines), with broad yellow 
thoracic fascie. 
Cyllene guttata (p. 47). 
To the localities given, add:—Mexico, Las Vigas, Almolonga (Hége); GuatTEMALa, 
La Gavia, Cahabon, Rio Maria Linda, Cerro Zunil, Mirandilla, Paraiso, El Reposo 
(Champion); Panama, Volcan de Chiriqui, Bugaba (Champion). 
Cyllene crinicornis (p. 47). 
To the localities given, add :—Mexico, Tuxtla, Izucar (Sallé), Guajuco in Nuevo 
Leon (Dr. Palmer); Guatemaua, San Isidro (Champion); Nicaracua (Sallé), Chontales 
(Belt); Panama, Tolé, San Feliz, Nancito, Bugaba (Champion). 
Common on felled or fallen timber in the more open parts of the forest-region of the 
“tierra caliente” of Chiriqui (Champion). 
The three preceding species are almost exactly alike in colours and markings, and are 
with difficulty distinguished. Of the characters mentioned by Chevrolat the chief are 
the number of the narrow yellow belts of the thorax, which are four in C. crinicornis, 
and three in C. erythropus and C. guttata ; the two last named are distinguished from 
each other by general form, C. erythropus being relatively much broader, especially 
at the base of the elytra. I find the shape of the yellow spot on the pygidium to be a 
good differentiating character; it is a narrow line in C. erythropus, and a large oval spot 
in C. guttata. 
The differences may be more readily seen in the following table :— 
Thorax fasciis flavis tribus. 
Elytra latiora, pygidium linea angusta flava . . . . . . . C. erythropus. 
Elytra angustiora, pygidium macula lata flava . . . . . . C. guttata. 
Thorax fasciis flavis quatuor . . . . 1. 1 eww ee Cu crinicornis. 
Cyllene mexicana (p. 47). 
This species is doubtful. Chevrolat, in his monograph, simply records it without 
remark, and it is not contained in the Sallé collection.
