The species may be listed as follows: 



^brevicollis (Sharp). 1887. Coatepeque, 1300 feet, Guatemala. 

 (Dalmodes) 



ensipes (Raffray). 1890. San Esteban, Venezuela. [Dalmodes) 



(May be the type of a new genus) 



humilis (Raffray). 1908. Guadeloupe, Leeward Islands. (Dalmodes) 



plicatulus (Schaufuss). 1882. Cayenne, French Guiana. (Trichonyx) 



punctipennis Raffray. 1908. Cayenne, French Guiana. Genotype. 



schaufussi (Raffray). 1896. Teapa, Mexico. [Dalmodes.) (Also 

 recorded with doubt from New Orleans, 

 Louisiana, and Yucatan, Mexico) 



venustulus (Schaufuss). 1872. Teapa, Mexico. [Trichonyx) 



HARMOPHOLA (Raffray, 1896) 



This is a monotypic genus in which the elytral flank has a longitudinal 

 sulcus and two basal elytral foveae and the pronotum has both a transverse sub- 

 basal sulcus and a lateral longitudinal sulcus on each side. The lateral pronotal 

 sulci differentiate the genus from its allies. 



clavata Raffray. 1896. Colonia Alpina, Brazil. Genotype. 



HARMOPHORUS (Schaufuss, 1886) 



This is a monotypic genus in which the elytra are similar to Harmophola, 

 but the pronotum lacks the longitudinal lateral sulci and has a well-formed 

 transverse subbasal sulcus. The eyes are very large but not visible from a dorsal 

 viewpoint because the sides of the head are dilated. The integuments are 

 strongly punctate. 



manticoroides Schaufuss. 1886. Brazil. Genotype. 

 * However, see Dalmoburis.
