The determination of small species of Pelonium is a matter of great difficulty ; with- 
out a series of specimens it is impossible to know to what extent they may vary. There 
is only a single specimen of this among Champion’s captures; and it varies from the 
species figured by Spinola in having the head red with a black vitta on the crown ; the 
thorax is black, marked with testaceous in front on each side and on the tubercles; 
and the elytra are narrower; the thorax also is longer. But I think it better to refer 
it with some doubt to this species, than to make a type of a doubtful specimen. 
P. flavolimbatum is another nearly allied species. 
9. Pelonium quadrisignatum. 
Pelonium quadrisignatum, Spin. Mon. i. p. 365", t. 33. f. 3. 
Hab. Mexico, Cordova (Sallé); GuatemaLa, Chacoj, Chiacam, Volcan de Atitlan, 
Teleman, Zapote (Champion) ; British Honpuras, Rio Sarstoon (Blancaneaux); PANAMA, 
Bugaba (Champion).—Soutu AMErRicA, Colombia ?. 
Var.? Hlytris linea basali juxta suturam maculaque lineari subapicali nigris. 
Hab. Payama, Volcan de Chiriqui (Champion). 
Very closely allied to P. hwmerale, Spin., which, however, has the apex of the elytra 
black, whereas in this species the spot is subapical and separated at the suture and 
indented on the apical side. The antenne in this and allied species are ten-jointed, a 
fact not noticed by Spinola or Lacordaire. 
There is a closely allied species in Brazil, which has a shorter and much more finely 
punctured thorax. In the Bugaba specimen the humeral spot is wanting. 
10. Pelonium bilineicolle. (Tab. IX. fig. 12.) 
Pelonium bilineicolle, Chevr. Rev. et Mag. Zool. 1874, p. 76°. 
Hab. Mexico !, Cordova, Toxpam (Sallé); Guatemaa, Capetillo, Cerro Zunil, Pana- 
achel (Champion); Panama, David, Chiriqui (Champion). 
Scarcely distinct from the preceding. The humeral spot is wanting, and the subapical 
one is reduced to an angulated fascia; the thorax has two lines or the disk entirely 
black; in some specimens the club of the antenne is infuscate: but these trivial characters 
can scarcely be considered of specific value.
