description closely. The prozonites are very dark brown, the meta- 

 zonites light brown or tan ; keels, antennae, legs, and last tergite yellow. 

 In the male the apical prongs of the gonopod are not bent to the extent 

 shown in Pocock's figure, but the difference in this respect is hardly 

 significant.

Guatemala: Chimaltenango, La Jolla Grande (Finca Monserrat), 

 northwest slope of Volcan de Fuego, 5,700 feet, May 3, 1948, K. L. Wen- 

 zel and E. D. Mitchell collectors (Chicago Natural History Museum).

 Walters collectors (Cliicago Natural History Museum). 



This species has previously been recorded from La Ceiba, Honduras 

 (the type locality) and Livingston, Guatemala. The following locali- 

 ties represent considerable range extensions for orphinus, which 

 appears to be one of the most abundant and widespread members of 

 the genus. The record from Chimaltenango, Guatemala, is of especial 

 interest in carrying the range up into the high mountains.
