Mexico, April 12, 1908, by Frederick Knab, and a male collected at 
Finca Trece Aguas, Alta Vera Paz, Guatemala, at an altitude of 900 
feet, April 9, 1906, by Schwarz and Barber. The specimen from

Genus BRACHYS Solier. 
Brachys Sou1ER, Ann. Soc. Ent. France, ser. 1, vol. 2, 1833, pp. 312-313. 
About 100 species have been described in this genus and their dis- 
tribution is confined to the Western Hemisphere. Of this large 
number of species, 9 have been described from the United States, 
13 from Mexico and Central America, and the remainder from South 
America. The species of this genus attain their highest develop- 
ment in the tropical parts of South America. 
Brachys chapuisi described by Dugés from Mexico * belongs to the 
genus Pachyschelus. 
The following species described from Mexico and Central America 
have been omitted from the key, as it has been impossible to corre- 
late the characters given in the original descriptions with those used 
in the key, and the writer has been unable to examine any specimens 
of these species: hexagonalis Dugés, from Mexico; scapulosus Chevy- 
rolat, from Mexico; suavis, taciturnus, and debilis, all described by 
Kerremans, from Guatemala.
