is synonymous with X. fallax, Mikl. Numerous allied forms, undescribed as yet, are 
known from South America.

Hab. Panama, Bugaba, Volcan de Chiriqui, David, Caldera, Tolé (Champion).— 
CoLomBiA, Cartagena! (coll. F. Bates). 
Found in abundance in Chiriqui in company with X. fulgidus and X. fallax. 
Chiriqui examples agree perfectly with an individual from Cartagena in Mr. F. Bates’s 
collection. This species is readily separated from X. fallax by its smaller size and 
posteriorly constricted thorax. 
CTEISA. 
Cteisa, Solier, Ann. Soc. Ent. Fr. iv. p. 242 (1835); Lacordaire, Gen. Col. v. p. 516 (1859). 
This Tropical-American genus contains three or four closely allied species ; two only 
have been described as yet, one of which extends northwards to the State of Panama. 
The three other species enumerated in Gemminger and Harold’s catalogue are doubtfully 
distinct from these. 
1. Cteisa pedinoides. (Tab. XXI. fig. 13.) 
Cteisa pedinoides (Dej.), Makl. Act. Soc. Fenn. x. p. 681°. 
Hab. Panama, Bugaba, Volcan de Chiriqui, Caldera, David, Tolé (Champion).— 
CotomBiaA!; VENEZUELA, Cumana. 
Found in plenty by myself in Chiriqui, chiefly in the savanna region of the low 
country. Miaklin’s description appears to have been made from an abraded example. 
C. pedinoides is closely allied to the Brazilian C. hérta, Sol.; it differs in its smaller 
size, shorter antennz, and in the sides of the thorax being rather straighter behind. 
The anterior tibiz are slightly dilated on the inner side about the middle in the male. 
The pubescence and sculpture of the upper surface is similar to that of C. hirta. 
Fam, OTHNIIDA. 
The single known genus of this family was placed by Pascoe in the Melandryide, 
and by Leconte (Class. Col. N. A. p. 102) as a separate family in the Clavicorn-series 
near the Cryptophagide. Leconte and Horn, however, in the second edition of the 
‘Classification of the Coleoptera of North America’ (p. 391), place the Othniide in the 
Heteromerous-series immediately after the Cistelide.
